Description

LH1550AT1/ LH1550AAB1 LH1550AAB1TR – 1 Form A High-Voltage Solid State Relay – Vishay Solid State Relays LH1550AT1 The LH1550 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 similar to the LH1540 but has a characteristically higher On resistance. It is con- structed using a GaAIAs LED for actuation control and an integrated monolithic die for the Switch output. The die, fabricated in a High-Voltage dielectrically iso- lated technology, is comprised of a Photodiode array, Switch control circuitry and MOSFET switches. In addition, it employs current-limiting circuitry which meets FCC 68.302 and other regulatory voltage surge requirements when overvoltage protection is provided. By Vishay Intertechnology
