Microelectronic Power IC
HEXFET Power MOSFET Photovoltaic Relay
®
Single Pole, Normally Open
0-60V DC, 1.5A
General Description
The PVDZ172N Photovoltaic Relay is a single-pole,
normally open solid state relay that can replace elec-
tromechanical relays used for general purpose switch-
ing of DC loads. It utilizes International Rectifier’s HEX-
FET power MOSFET as the output switch, driven by
an integrated circuit photovoltaic generator of novel con-
struction. The output switch is controlled by radiation
from a GaAlAs light emitting diode (LED) which is opti-
cally 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 con-
tact bounce, long operational life, insensitivity to exter-
nal magnetic fields, shock and vibration, and high reli-
ability 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.
