FOD2742BR1V

Overview

The FOD2742BR1V is a transistor output optocoupler manufactured by onsemi. It features a single channel with 2500Vrms isolation voltage and operates within a temperature range of -25°C to 85°C. The device utilizes an 8-SOIC package. Key electrical parameters include a collector-emitter saturation voltage of 400mV maximum, a forward voltage of 1.2V typical, and a current transfer ratio ranging from 100% to 200% at 10mA input current. The output can handle up to 50mA per channel with a maximum output voltage of 70V.

Feature Summary

Provides galvanic isolation between input and output circuits
Utilizes a gallium arsenide infrared LED coupled with a silicon phototransistor
Designed for high-speed signal transmission applications

Applications
