LH1546ADF Datasheet PDF - Vishay Semiconductor

●The LH1546ADF is a Solid State Relay with SPST-NO contact and surface-mount terminals. This 1-form-A relay 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. 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.
