Overview
The FODM8801AR2, part of the OptoHiT series from onsemi, is a high-temperature phototransistor optocoupler. 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 designed to deliver a high current transfer ratio at very low input current and features high input-output isolation voltage rated at 3750 VACRMS.
