PVO402P

Microelectronic

Power IC Relay

Dual Pole, Normally Open + Ring Detector

0-400V, 120mA AC/DC

(HEXFET is the registered trademark for International Rectifier Power MOSFETs)

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.
