MOC8104

Transistor, Photovoltaic Output Optoisolators Overview

The MOC8104 is a single-channel optoisolator featuring a gallium arsenide infrared emitting diode optically coupled to a phototransistor output. It provides high isolation voltage of 5300Vrms and supports a collector-emitter voltage of 30V with a maximum output current of 50mA per channel. The device operates within a temperature range of -55°C to 100°C. Typical switching characteristics include an on-time of 3µs and off-time of 2.3µs, with rise and fall times of 2µs each. The current transfer ratio ranges from 160% to 256% at a forward current of 10mA.
