HEXFET Power MOSFET Photovoltaic Relay
Data Sheet No. PD 10037 revI
Series PVT422PbF
Microelectronic Power IC
?
Dual Pole, Normally Open
0-400V, 120mA AC/DC
General Description
Features
The PVT422 Series Photovoltaic Relay is a dual-
pole, normally open solid-state relay that can replace
electromechanical relays in many applications. It util-
izes International Rectifier’s HEXFET power MOSFET
as the output switch, driven by an inte grated circuit
photovoltaic gen erator of novel construction. The
output switch is con trolled by radiation from a GaAlAs
light emit ting diode (LED) which is optically isolated
from the photovol taic generator.
Series PVT422 Relays are packaged in an 8-pin,
molded DIP package with either thru-hole or surface
mount (gull-wing) termi nals. It is avail able in standard
plastic ship ping tubes or on tape-and-reel. Please refer
to Part Identifica tion in formation opposite.
