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.

FEATURES

• Dual channel

• Current limit protection

• Isolation test voltage 5300 VRMS

• Typical RON 22 Ω

• Load voltage 350 V

• Load current 140 mA

• Clean bounce free switching

• Low power consumption

• Material categorization: for definitions of compliance
