Power MOSFET Relay
Single Pole, Normally Open + Ring Detector
0-400V, 150mA AC/DC
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 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
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 (oppo-
site) for details.
