PVO402继电器的固态继电器规格书PDF中文资料

Microelectronic Power IC Relay Dual 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’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 PVO402P has two LEDs in inverse parallel connection as the input sensing element and a silicon NPN photo-transistor as the output switch.
