Vishay, LH1540AAB MOSFET Output Optocoupler, Surface Mount, 6-Pin SMD

The LH1540 is robust, ideal for telecom and ground fault applications. It is an SPST normally open switch (1 Form A) that replaces electromechanical relays in many applications. It is constructed using a GaAlAs LED for actuation control and MOSFETs for the switch output. In addition, it employs current-limiting circuitry to provide overvoltage protection.
