Description

Dual 1 Form A Solid State Relay

The LH1556FPTR is robust, ideal for telecom and ground fault applications. It contains two SPST normally open switches (1 Form A) that replace electromechanical relays in many applications. It is constructed using a GaAs LED for actuation control and an integrated monolithic die for the switch output. The die, fabricated in a high-voltage dielectrically isolated BCDMOS technology, is comprised of a photodiode array, switch control circuitry and MOSFET switches. In addition, LH1556FPTR employs current-limiting circuitry which meets FCC 68.302 and other regulatory voltage surge requirements when overvoltage protection is provided.
