PVO402P
HEXFET® POWER MOSFET PHOTOVOLTAIC RELAY
Microelectronic
Power IC Relay
Dual Pole, Normally Open + Ring Detector
0-400V, 120mA AC/DC
General Description
The PVO402P Photovoltaic Relay is a dual-pole,
normally open solid-state relay plus ring detec-
tor. By integrating these two functions in one
package it can replace two discrete components,
i.e., a relay and an AC-input opto-coupler. The
relay portion of PVO402P utilizes International
Rectifier’s HEXFET power MOSFET as the out-
put 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 opti-
cally isolated from the photovoltaic generator.
The ring detector portion of PVO402P has two
LEDs in inverse parallel connection as the input
sensing element and a silicon NPN photo-tran-
sistor as the output switch.
PVO402P is ideally suited for PCMCIA fax/mo-
dem cards. Its extremely low profile allows it to
be used in Type II cards whose outer shells are
only 5mm thick.
PVO402P Relays are packaged in an 8-pin,
molded ‘Thin-Pak’ DIP package with ‘gull-wing’
surface mount terminals. It is available in plastic
shipping tubes or on tape-and-reel. Please refer
to Part Identification (opposite) for details.
