DESCRIPTION

The LH1518 is an SPST normally open switch (1 Form A)

that can replace electromechanical relays in many

applications. The relay is constructed using a GaAlAs LED

for actuation control and high reliable MOSFETs for the

output switch. In addition, it employs current-limiting

circuitry to provide overvoltage protection. The LH1518

provides current limiting also for unidirectional DC

applications.
