DESCRIPTION

The LH1546AD is a single channel solid state relay in a

4 pin SMD package. It is a SPST normally open switch

(1 Form A) that replaces electromechanical relays in many

applications. It is constructed using a GaAlAs LED for

actuation control and MOSFET switches for the output.

In addition, it employs current-limiting circuitry to provide

overvoltage protection.
