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

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.
