Product Summary
The LH1546ADF (4 pin DIP) is a kind of 1 Form A Solid-State Relay. It is an 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, the LH1546ADF 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. The LH1546ADF is ideal for General telecom switching, Instrumentation and Industrial controls.
