DESCRIPTION
.100 (2.54) Typ.
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

RMS
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 Ω 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.
