LH1546ADF

VISHAY LH1546AD/ ADF/ ADFTR Vishay Semiconductors 1 Form A Solid State Relay Features Current Limit Protection Isolation Test Voltage 5300 VRMS Typical RON 28 Ω Load Voltage 350 V Load Current 120 mA High Surge Capability Linear, AC/DC Operation Clean Bounce Free Switching Low Power Consumption High Reliability Monolithic Receptor A 1 K 2 4 S S i179058 S' 3 S1 SMT Lead Available on Tape and Reel Description The LH1546AD (4 Pin DIP) 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 GaAs LED for actuation control and an integrated monolithic die for the switch output. The die, fabricated in a high-voltage dielectrically isolated BCDMOS 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.
