Series PVT312PbF
Microelectronic Power IC
HEXFET® Power MOSFET Photovoltaic Relay
Single Pole, Normally Open, 0-250V, 190mA AC/DC
General Description
The PVT312 Photovoltaic Relay is a sin gle-pole,
normally open solid-state re lay that can replace
electromechani cal re lays in many applications. It util-
izes International Rectier’s proprietary 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.
This SSR is specically designed for tele com applica-
tions. PVT312L employs an active cur rent-limiting cir-
cuitry enabling it to withstand current surge transients.
PVT312 Relays are packaged in a 6-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 the
Part Identica tion in formation opposite.
