The relay can control AC or DC loads currents up to 100 mA, with a supply voltage up to 350 V. The device is packaged in a six pin 0.3 inch dual-in line package. This package offers an insulation dielectric withstand of 7500 VACPK. The coupler consists of a 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 30 Ω at 25 mA and is linear up to 50 mA. The incremental resistance drops to less than 20 Ω beyond 50 mA while reducing internal power dissipation at high load currents. There is built-in current limiting circuitry in the detector chip. 2 5 3 4 S NC S' .300 (7.62) Typ. .130 (3.30) .150 (3.81) 18° Typ. .020 (.051) Min. .031 (0.80) .035 (0.90) .100 (2.54) Typ.
