LH1500AAB

The LH1500AAB is a SMD 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
