ESD, lightning, and other voltage-induced transient
events. They are available with operating voltages of
5V, 12V, 15V and 24V.

IEC 61000-4-2 (ESD) 15kV (air), 8kV (contact)
IEC 61000-4-4 (EFT) 40A (5/50ns)
IEC 61000-4-5 (Lightning) 12A (8/20µs)
u Small package for use in portable electronics
u Two devices will protect one line
u Low capacitance for high-speed data lines
u Working voltages: 5V, 12V, 15V and 24V
u Solid-state silicon avalanche technology
TVS diodes are solid-state devices designed specifically
for transient suppression. They offer desirable charac-
teristics for board level protection including fast re-
sponse time, low operating and clamping voltage and
no device degradation. The SL series devices feature
a low capacitance, fast switching compensation diode
in series with a standard TVS diode. This effectively
reduces the overall capacitance of the device to less
than 5pF making it an integrated, low capacitance
solution for use on high-speed interfaces.

Applications Information
Device Connection for Protection of One High-Speed
Data Line
SL Connection Options
The SL series devices are designed to protect high-
speed data lines. The SLxx utilizes a low capacitance
compensation diode in series with, but in opposite
polarity to a TVS diode in each line to achieve an
effective capacitance of less than 5pF per device.
During a transient event, the internal rectifier must be
forward biased (TVS is reversed biased). Therefore,
each device will only suppress transient events in one
polarity. To achieve protection in both positive and
negative polarity, a second device is connected in anti-
parallel to the first. On unidirectional lines, a fast
switching steering diode may be used as an alternative
to using two SL devices.
Two Devices : Bidirectional or
Unidirectional Line
The options for connecting the devices are as follows:
l
Low capacitance protection of one high-speed
line: Protection of one unidirectional or bidirec-
tional high-speed line is achieved by connecting two
devices in anti-parallel. Pin 1 of the first device is
connected to the line and pin 2 is connected to
ground (or to a second line for differential protec-
tion). Pin 2 of the second device is connected to
line 1 and pin 1 is connected to ground (or line 2)
as shown. Pin 3 is not connected. During positive
duration transients, the first device will conduct
from pin 1 to 2. The steering diode conducts in the
forward direction while the TVS will avalanche and
conduct in the reverse direction. During negative
transients, the second device will conduct in the
same manner. For optimum protection, the ground
connections should be made directly to the ground
plane for best results. The path length is kept as
short as possible to reduce the effects of parasitic
inductance in the board traces. The path length
between the TVS and the protected line should
also be minimized.
One Devices with Steering Diode :
Unidirectional Line Only
I/O Line Protection
l
Connection Option for Unidirectional Lines Only:
An optional method for protecting unidirectional
(normal signal polarities above ground) lines is to
add a fast switching steering diode in parallel to the
SL TVS. Input/outputs are connected to pin 1 of
the SL device and the cathode of the rectifier. The
anode of the diode and pin 2 of the SL TVS are
connected to ground.
