DESCRIPTION
The IL356 is a single pole single throw (SPST), nor-
mally open (NO), solid state relay. The relay can con-
trol AC or DC loads currents up to 100 mA, with a
supply voltage up to 400 V. The device is packaged in
a eight pin 2 mm surface mount package. This pack-
age offers an insulation dielectric withstand of 2500
VRMS.
The coupler consists of an AlGaAs LED that is opti-
cally coupled to a dielectrically isolated photodiode
array which drives two series connected high voltage
MOS transistors. The typical ON-Resistance is 25 W at
25 mA lead current and is linear up to 50 mA. The
incremental resistance drops to less than 20 W
beyond 50 mA while reducing internal power dissipa-
tion at high load currents. There is built-in current limit-
ing circuitry in the detector chip.
