PVDZ172NPbF
Microelectronic Power IC
HEXFET ? Power MOSFET Photovoltaic Relay
Single Pole, Normally Open
0-60V DC, 1.5A
4,000 V RMS I/O Isolation
General Description
The PVDZ172N Photovoltaic Relay is a single-pole,
normally open solid state relay that can replace
electromechanical relays used for general purpose
switching of DC loads. It utilizes International Rectifier’s
HEXFET power MOSFET as the output switch, driven
by an integrated circuit photovoltaic generator of novel
construction. The output switch is controlled by radia-
tion from a GaAlAs light emitting diode (LED) which
is optically isolated from the photovoltaic generator.
These units overcome the limitations of both electro-
mechanical and reed relays by offering the solid-state
advantages of high sensitivity, miniaturization, no
contact bounce, long operational life, insensitivity to
external magnetic fields, shock and vibration, and high
reliability inherent with solid state technology. They are
ideally suited for switching high currents or low level
signals without distortion or injection of electrical noise.
These relays are packaged in 8-pin, molded DIP pack -
ages and available with thru-hole and surface-mount
(gull-wing) leads, in plastic shipping tubes.
