LH1500AT Datasheet PDF - Vishay Semiconductor

●The LH1500AT is a through-hole robust Solid-State Relay 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. The die, fabricated in a high-voltage dielectrically isolated technology, is comprised of a photodiode array, switch control circuitry and MOSFET switches. In addition, it employs current-limiting circuitry which meets lightning surge testing as per ANSI/TIA-968-B and other regulatory voltage surge requirements when overvoltage protection is provided.

● Current limit protection

● High surge capability

● Clean bounce free switching

● Low power consumption
