2 Form A Solid-State Relay

DESCRIPTION

The LH1503 relays are DPST normally open switches

(2 form A) that can replace electromechanical relays in many

applications. The relays are constructed using a GaAlAs

LED for actuation control and an integrated monolithic die

for the switch output. The die, fabricated in a high voltage

dielectrically isolated technology, is comprised of a

photodiode array, switch control circuity, and DMOS

switches. In addition, these relays employ current limiting

circuity, enabling them to pass lightning surge testing as

per ANSI/TIA-968-B and other regulatory voltage surge

requirements when overvoltage protection is provided.

FEATURES

• Current limit protection

• Load voltage 350 V

• Load current 110 mA

• High surge capability

• Clean bounce free switching

• Low power consumption

• High reliability monolithic receptor

• SMD lead available on tape and reel

• Compliant
