Data Sheet No. PD 10038 revL
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 single-pole,
normally open solid-state relay that can replace
electromechanical relays in many applications. It util
izes International Rectifier’s proprietary 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.
This SSR is specifically designed for telecom applica-
tions. PVT312L employs an active current-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”) terminals. It is available in standard plastic
shipping tubes or on tape-and-reel. Please refer to the
Part Identification information opposite.
