DESCRIPTION
Load Voltage Rating
The SR75-2 solid-state relay utilizes a
power FET switch that is protected
against overload and short-circuit
currents. The short-circuit protection
feature not only provides protection
should a short or overload occur while
the relay is on, but will also provide
protection should the relay be switched
into a short. Once the protection trips
the relay, it will remain off until reset by
cycling the input control line. Using the
SR75-2 to switch power sources and
loads can prevent fires, damage to
system assemblies and system wiring.
The power FET output offers low “ON”
resistance and can switch loads in
either the high or the low side of the
power line. The SR75-2 is packaged in
a 16-pin DIP package with either
surface-mount or through-hole mounting
available.

NOTES:
1. The input voltage is 5.0 Vdc for all tests unless otherwise
specified.
2. Reversing the output polarity when the relay is in overload or
is sustaining a short circuit may cause permanent damage.
3. Inductive loads must be diode suppressed.
4. Loads may be switched in either the high side or the low side
of the power source.
5. Continuous load current rating is determined with relay
mounted on a printed circuit card.
6. For input voltage greater than 6.0 Vdc a series resistor must
be used to limit the power dissipation on the input of the
relay. The resistor value should be selected using the
following equation:
R = (VBIAS - 6 volts)/11mA
7. Input transitions are to be less than 1 msec.
8. Tested at 25°C ambient.
