The relay can control 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 package offers an insulation dielectric withstand of 2500 VRMS. The coupler consists of an AlGaAs LED that is optically 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 dissipation at high load currents. There is built-in current limiting circuitry in the detector chip.
