IL213AT

Transistor, Photovoltaic Output Optoisolators Overview

The IL213AT is a single-channel optocoupler manufactured by Vishay Semiconductor Opto Division. It features a Gallium Arsenide infrared LED coupled to a silicon NPN phototransistor with base access. The device provides 4000Vrms isolation voltage and operates within a temperature range of -55°C to 100°C. Key electrical parameters include a maximum forward current of 60 mA, a typical forward voltage of 1.3 V, and a minimum current transfer ratio of 100% at 10 mA input. The collector-emitter saturation voltage is maximized at 400 mV, with a maximum output voltage of 30 V. Switching times are typically 3 µs for both turn-on and turn-off.
