PVO402AP

Microelectronic Power IC

Single Pole, Normally Open + Ring Detector

0-400V, 150mA AC/DC

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

General Description

The PVO402AP Photovoltaic Relay is a single

pole, normally open solid-state relay plus ring

detector. By integrating these two functions in

one package it can replace two discrete compo-

nents, i.e., a relay and an AC-input opto-coupler.

The relay portion of PVO402AP utilizes Interna-

tional Rectifier’s 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 opti-

cally isolated from the photovoltaic generator.

The ring detector portion of PVO402AP has two

LEDs in inverse parallel connection as the input

sensing element and a silicon NPN photo-tran-

sistor as the output switch.

PVO402AP 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.

PVO402AP 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.
