1 Form A, Dual 1 Form A
SOP Solid-State Relays
FEATURES
DESCRIPTION
The LH1525 relay is an SPST normally open switche (1 Form A
and Dual 1 Form A respectively) in small-outline packages (SOP).
They require a minimal amount of LED drive current to operate,
making them ideal for battery powered and power consumption
sensitive applications.
• High-speed operation
• 1500 Vrms I/O isolation
• Current-limit protection
• High surge capability
• Linear, ac/dc operation
• Clean, bounce-free switching
• Extremely low power consumption
• High-reliability monolithic receptor
• Surface-mountable
The relays are constructed using a GaAlAs LED for actuation
control and an integrated monolithic die for the switch output.
The die, fabricated in a high-voltage dielectrically isolated
BCDMOS technology, is comprised of a photodiode array, switch-
control circuitry, and MOSFET switches. In addition, the relays
employ current-limiting circuitry enabling it to pass FCC 68.302
and other regulatory surge requirements when overvoltage
protection is provided.
APPLICATIONS
• PCMCIA Type 2 cards
• Battery powered switch applications
• General telecom switching
• Telephone line interface
– On/off hook
The LH1525 (1 Form A) is packaged in an 8-pin, plastic SOP
(LH1525ACD). Available in sticks or on tape and reel.

Functional Description
In a 1 Form A relay, to turn the relay on, forward current
is applied to the LED. The amount of current applied
determines the amount of light produced for the photo-
diode array. This photodiode array develops a drive-
voltage for the MOSFET switch outputs. For high-
temperature or high-load current operations, more LED
current is required.
Figure 3 shows the switch characteristics of the relays.
The relay exhibits an ON-resistance that is exception-
ally linear through the origin and up to the knee current
(Ik). Beyond Ik, the incremental resistance decreases,
minimizing internal power dissipation. Overload
currents are clamped at ILMT by the internal current-limit
circuitry. The current-limiting circuitry exhibits a nega-
tive temperature coefficient, thereby reducing the
current-limit value when relay temperature is increased.
An extended clamp condition, which increases relay
temperature, decreases the current-limit value,
resulting in a current foldback characteristic. When the
overload is removed, the relay resumes its normal ON-
resistance characteristic.
Thermal Considerations
To minimize thermal resistance, pins 6 and 7 of the
LH1525ACD are formed into a tab. This tab should be
soldered to a printed circuit board land pattern of equal
or greater size. Do Not run metal underneath the
device or the input-to-output isolation could be jeopar-
dized.

DESCRIPTION
The LH1533 (Dual 1 Form A) relays are SPST normally open
switches that can replace electromechanical relays in many appli-
cations. The relays are constructed using a GaAlAs LED for actua-
tion control and an integrated monolithic die for the switch output.
The die, fabricated in a high-voltage dielectrically isolated

DESCRIPTION
The LH1525 and LH1526 relays as SPST normally open switches
(1 Form A) that can replace electromechanical relays in many
applications. The relays require a minimal amount of LED drive
current to operate, making it ideal for battery-powered and power
consumption sensitive applications. The relay is constructed using
a GaAIAs LED for actuation control and an integrated monolithic
die for the switch output. The die, fabricated in a high-voltage
dielectrically isolated BCDMOS technology, comprised of a photo-
diode array, switch-control circuitry, and MOSFET switches. In
addition, the relay employs current-limiting circuitry, enabling it to
pass FCC 68.302 and other regulatory surge requirements when
overvoltage protection is provided. The relay can be configured for
ac/dc or dc-only operation.

Figure 1. Input Control Circuit
APPLICATIONS
Input Control
VS
The LH1525 low turn-on current SSR has highly sensi-
tive photo-detection circuits that will detect even the
most minute currents flowing through the LED. Leakage
current must be considered when designing a circuit to
turn on and off these relays.
R1
2700 W
R2
100 kW
ANY TTL OR
BUFFERED CMOS
LOGIC
Figure 23 shows a typical logic circuit for providing LED
drive current. R1 is the input resistor that limits the
amount of current flowing through the LED. For 5 V
operation, a 2700 W resistor will limit the drive current to
about 1.4 mA. Where high-speed actuation is desire-
able, use a lower value resistor for R1. An additional RC
peaking circuit is not required with the LH1525 relay.
SSR
R2 is an optional pull-up resistor which pulls the logic
level high ouput (V ) up toward the V potential. The
OH
S
pull-up resistance is set at a high value to minimize the
overall current drawn from the V . The primary purpose
S
of this resistor is to keep the differential voltage across
the LED below its turn-on threshold. LED dropout
voltage is graphed vs. temperature in the Typical
Performance Characteristics section. When the logic
gate is high, leakage current will flow through R . R will
2
2
draw up to 8 mA before developing a voltage potential
which might possibly turn on the LED.
Many applications will operate satisfactorily without a
pull-up resistor. In the logic circuit in Figure 1 the only
path for current to flow is back into the logic gate. Logic
leakage is usually negligible. Each application should
be evaluated, however, over the full operating tempera-
ture range to make sure that leakage current through
the input control LED is kept to a value less than the
minimum LED forward current for switch turn-off
specification.

LH1191
High-Voltage Solid State Relay
FEATURES
DESCRIPTION
The LH1191 High-Voltage, Solid State Relay is a single pole,
normally open switch (1 Form A) that can replace electromechan-
ical relays in many applications. The relay features logic-level input
control of isolated high-voltage switch outputs. The output is rated
at 280 V and can handle loads up to 120 mA. The relay can switch
both ac and dc loads and is ideal for audio frequency or dc appli-
cations. Typical ON-resistance at 25 mA is 25 W.
• 1500 Vrms input/output isolation
• High-surge capability
• Low ON-resistance
• Clean, bounce-free switching
• dv/dt typically better than 500 V/ms
• Low power consumption
• Monolithic IC reliability
The LH1191 relay consists of a GaAIAs LED that optically couples
control signals to a monolithic integrated circuit. Optical coupling
provides 1500 Vrms of input/output isolation. The integrated circuit
is a dielectrically isolated, high-voltage die comprised of photo-
diode arrays, switch control circuitry, and high-voltage DMOS tran-
sistor switches.
APPLICATIONS
• Telecom switching
• Transducer driver
• High-voltage testers
• Industrial controls
• Triac predriver
In operation, the device is exceptionally linear up to 55 mA.
Beyond 55 mA, the incremental resistance decreases, thereby
minimizing internal power dissipation. Overload currents are
clamped at 210 mA by internal current limiting. An extended clamp
condition, which increases relay temperature, results in a reduction
in clamp current, thereby further reducing internal power dissipa-
tion and preserving the relay’s integrity. The relay is packaged
in a 6-pin, plastic DIP (LH1191AT1) or in a 6-pin, surface-mount,
gull-wing configuration (LH1191AAB1).

LH1085
High-Voltage Solid State Relay
FEATURES
DESCRIPTION
The LH1085 High-Voltage, Solid State Relay is a single pole,
normally open switch (1 Form A) that can replace electromechan-
ical relays in many applications. The relay features logic-level input
control of isolated high-voltage switch outputs. The output is rated
at 350 V and can handle loads up to 135 mA. The relay can switch
both ac and dc loads and is ideal for audio frequency or dc appli-
cations. Typical ON-resistance at 25 mA is 30 W.
• 1500 Vrms input/output isolation
• Low ON-resistance
• Clean, bounce-free switching
• dv/dt typically better than 500 V/ms
• Low power consumption
• Monolithic IC reliability
The LH1085 relay consists of a GaAIAs LED that optically couples
control signals to a monolithic integrated circuit. Optical coupling
provides 1500 Vrms of input/output isolation. The integrated circuit
is a dielectrically isolated, high-voltage die comprised of photo-
diode arrays, switch control circuitry, and high-voltage DMOS tran-
sistor switches.
APPLICATIONS
• High-voltage testers
• Industrial controls
• Telecom switching
• Triac predriver
• Isolation switching
In operation, the device is exceptionally linear up to 45 mA.
Beyond 45 mA, the incremental resistance decreases, thereby
minimizing internal power dissipation. Overload currents are
clamped at 300 mA by internal current limiting. An extended clamp
condition, which increases relay temperature, results in a reduction
in clamp current, thereby further reducing internal power dissipa-
tion and preserving the relay’s integrity. The relay is packaged
in a 6-pin, plastic DIP (LH1085AT1) or in a 6-pin, surface-mount,
gull-wing configuration (LH1085AAB1).
