MOCD208M

Transistor, Photovoltaic Output Optoisolators Overview

The MOCD208M is a dual-channel transistor output optocoupler manufactured by onsemi. It integrates two gallium arsenide infrared emitting diodes optically coupled to two monolithic NPN phototransistors in an 8-pin SOIC narrow package. The device provides an isolation voltage of 2500 Vrms and supports a maximum collector-emitter voltage of 70 V. Key electrical parameters include a minimum current transfer ratio of 40% and a maximum of 125% at 10 mA forward current. It features a maximum forward current of 60 mA, typical rise/fall times of 3.2 µs/4.7 µs, and operates within a temperature range of -40°C to 100°C.
