MCT210SD

Transistor, Photovoltaic Output Optoisolators Overview

The MCT210SD is a phototransistor optocoupler manufactured by Fairchild Semiconductor, now part of onsemi. It features a single channel with a gallium arsenide infrared emitting diode coupled to a silicon phototransistor output with a base terminal. The device provides high isolation voltage of 5300Vrms and operates within a temperature range of -55°C to 100°C. Packaged in a 6-SMD Gull Wing configuration, it supports DC input and transistor output types. Key electrical parameters include a maximum collector-emitter breakdown voltage of 30V and a typical current transfer ratio ranging from 63% to 125% at 10mA forward current.
