DESCRIPTION

The LH1520 dual 1 Form A relays are SPST normally open

switches that can replace electromechanical relays in many

applications. They are constructed using a GaAIAs LED for

actuation control and MOSFET switches for the output. In

addition, the LH1520 SSRs employ current-limiting circuitry

to provide overvoltage protection.
