PD1201
DS-PD1201-R9
The PD1201 is an AC Solid State Switch using optical
coupling with dual power SCR outputs to produce an
alternative to optocoupler and Triac circuits. The PD1201
switches are robust enough to provide a blocking voltage
of up to 400V and max surge current rating of 20A. In
addition, tightly controlled zero cross circuitry ensures
switching of AC loads without the generation of tran-
sients. The input and output circuits are optically coupled
to provide 3750V of isolation and noise immunity
between control and load circuits. As a result the PD1201
is well suited for industrial environments where electro-
magnetic interference would disrupt the operation of
electromechanical relays.

Absolute Maximum Ratings are stress ratings. Stresses
in excess of these ratings can cause permanent damage
to the device. Functional operation of the device at these
or any other conditions beyond those indicated in the
operational sections of this data sheet is not implied.
Exposure of the device to the absolute maximum ratings
for an extended period may degrade the device and effect
its reliability.
