General Description
LH1540 General Description
The LH1540 is a single pole single throw (SPST), normally open (NO), solid state relay. 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 3750 VACRMS.
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 20 at 25 mA and is linear up to 50 mA.There is built-in current limiting circuitry in the detector chip,enabling it to pass FCC 68-302 and other regulatory voltage surge requirements when over voltage protection is provided
