HEXFET Power MOSFET Photovoltaic Relay
®
Microelectronic Power IC
PVAZ172NPbF
Single Pole, Normally Open
0-60V AC, 1.0A
The PVAZ172N Photovoltaic Relay is a single-pole,
normally open solid state relay that can replace
electromechanical relays used for general purpose
switching of DC and AC loads. It utilizes International
Rectifier’s HEXFET power MOSFETs as the output
switches, driven by an integrated circuit photovoltaic
generator of novel construction. The output switch
is controlled by radiation from a GaAlAs light emit-
ting 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 either thru-hole or surface-
mount (“gull-wing”) leads, in plastic shipping tubes.
