GENERAL DESCRIPTION
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. 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 ‘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. PVO402P ‘Thin-Pak’ APPLICATIONS
