PVO402AP
Microelectronic Power IC
HEXFET® Power MOSFET Relay
Single Pole, Normally Open + Ring Detector
0-400V, 150mA AC/DC
Features
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 components, i.e., a relay and an
AC-input opto-coupler. The relay portion of PVO402AP
utilizes International 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 optically isolated from
the photovoltaic generator. The ring detector portion of
PVO402AP has two LEDs in inverse parallel connec-
tion as the input sensing element and a silicon NPN
photo-transistor as the output switch.

PVO402AP is ideally suited for PCMCIA fax/modem
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 (oppo-
site) for details.
