DESCRIPTION

The AQY214S is a single pole throw (SPST), normally open (NO), Mos Relay. The relay can control AC or DC loads currents up to 130 mA, with a supply voltage up to 400 V. The device is packaged in a 4 pin SO package. This package offers an insulation dielectric withstand of 11500 VACRMS.

The coupler consists of a AIGaAs LED that is optically coupled to a dielectrically isolated photodiode array which drivers two series connected high voltage MOS transistors. The typical ON-Resistance is 20Ω at 25 mA and is linear up to 50mA. The incremental resistance drops to less than 20Ω beyond 50 mA while reducing internal power dissipation at high load currents.
