Overview
The FODM8801AV, part of the OptoHiT series from onsemi, is a high-temperature phototransistor optocoupler designed to operate in extreme conditions. This device utilizes onsemi’s proprietary process technology to achieve high operating temperature characteristics, up to 125°C. The optocoupler consists of an aluminum gallium arsenide (AlGaAs) infrared light-emitting diode (LED) optically coupled to a phototransistor, packaged in a compact half-pitch, mini-flat, 4-pin package. It is notable for its high current transfer ratio at very low input current and its high input-output isolation voltage of 3750 VACRMS.
