Series PVT322APbF
Microelectronic Power IC
HEXFET® Power MOSFET Photovoltaic Relay
Dual Pole, Normally Open
0-250V, 170mA AC/DC
(HEXFET is the registered trademark for International Rectier Power MOSFETs)
General Description
The PVT322A Series Photovoltaic Relay is a dual-
pole, normally open solid-state re lay that can replace
electromechani cal re lays in many applications. It util-
izes International Rectier’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 PVT322A 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 Identica tion in formation opposite.
