نظرة عامة على المنتج
The 4N25 from Vishay is a phototransistor output optocoupler with base connection, providing 5300Vrms input-to-output isolation voltage. It consists of a gallium arsenide infrared LED optically coupled to a silicon phototransistor, with a minimum current transfer ratio (CTR) of 20% at 10mA forward current.
