IL207AT

Transistor, Photovoltaic Output Optoisolators Overview

The IL207AT is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It integrates a gallium arsenide infrared LED with a silicon NPN phototransistor featuring a base connection. The device provides 4000Vrms isolation voltage and operates within a temperature range of -55°C to 100°C. Key electrical parameters include a maximum collector-emitter voltage of 70V, a forward current of 60mA, and a typical propagation delay of 3µs for both rise and fall times. It is housed in an 8-SOIC package.
