Overview
The FODM8801BR2V, part of the OptoHiT series from onsemi, is a high-temperature phototransistor optocoupler designed to operate in extreme conditions. This component 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. This design ensures high current transfer ratio (CTR) even at very low input currents, making it suitable for a variety of applications requiring reliable signal isolation and high temperature operation.
