Description

Vishay Solid State Relays (SSRs) are miniature, opti-

cally- coupled relays with high-voltage MOSFET out-

puts. The LH1518 relays are capable of switching AC

or DC loads from as little as nanovolts to hundreds of

volts.

The relays can switch currents in the range of nano-

amps to hundreds of milliamps. The MOSFET

switches are ideal for small signal switching and are

primarily suited for dc or audio frequency applica-

tions.

The LH1518 relays feature a monolithic output die

that minimizes wire bonds and permits easy integra-

tion of high-performance circuits such as current lim-

iting in normally-open switches. The output die

integrates the photodiode receptor array, turn-on and

turn-off control circuitry, and the MOSFET switches.

The optically-coupled input is controlled by a highly

efficient GaAlAs infrared LED.
