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.
