DESCRIPTION
APPLICATIONS
• General telecom switching
Vishay solid state relays (SSRs) are miniature, optically
coupled relays with high-voltage MOSFET outputs. The
LH1518 relays are capable of switching AC or DC loads from
as little as nanovolts to hundreds of volts.
• Instrumentation
• Industrial controls
The relays can switch currents in the range of nanoamps to
hundreds of milliamps. The MOSFET switches are ideal for
small signal switching and are primarily suited for DC or
audio frequency applications.
The LH1518 relays feature a monolithic output die that
minimizes wire bonds and permits easy integration of
high-performance circuits such as current limiting 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.
