Microelectronic
Power IC Relay
Dual Pole, Normally Open
0-400V, 120mA AC/DC
General Description
The PVT422 Series Photovoltaic Relay is a
dual-pole, normally open solid-state relay that can
replace electromechanical relays in many
applications. 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 radiation from a GaAlAs light
emitting diode (LED) which is optically isolated
from the photovoltaic generator.
Series PVT422 Relays are packaged in an 8-
pin, molded DIP package with either thru-hole or
"gull-wing" surface mount terminals. It is available
in standard plastic shipping tubes or on tape-and-
reel. Refer to Part Identification information.
