LH1540AAB - 1 Form A Solid State Relay

Download the LH1540AAB datasheet PDF. This datasheet also covers the LH1540AT variant, as both devices belong to the same 1 form a solid state relay family and are provided as variant models within a single manufacturer datasheet.

General Description

The LH1540 is robust, ideal for telecom and ground fault applications.

It is a SPST normally open switch (1 Form A) that replaces electromechanical relays in many applications.

It is constructed using a GaAIAs LED for actuation control and an integrated monolithic die for the switch output.
