Power MOSFET Relay
Single 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 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
PVO402P utilizes International Rectifier鈥檚 HEXFET
power MOSFET as the output switch, driven by an
integrated circuit photovoltaic generator of novel
construction. The output switch is controlled by ra-
diation from a GaAlAs light emitting diode (LED)
which is optically isolated from the photovoltaic gen-
erator. The ring detector portion of PVO402P has two
LEDs in inverse parallel connection as the input sens-
ing element and a silicon NPN photo-transistor as
the output switch.
PVO402P 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.
PVO402P Relays are packaged in an 8-pin, molded
鈥楾hin-Pak鈥?DIP package with 鈥榞ull-wing鈥?surface mount
terminals. It is available in plastic shipping tubes or
on tape-and-reel. Please refer to Part Identification
(opposite) for details.
