DESCRIPTION

The LH1550 is a single channel solid-state relay in a 6 pin

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.
