Overview
The FODM8801AR2V, part of the OptoHiT series from onsemi, is a high-temperature phototransistor optocoupler. This device is designed to operate at temperatures up to 125°C, making it suitable for a wide range of industrial and high-reliability applications. The optocoupler features an aluminum gallium arsenide (AlGaAs) infrared light-emitting diode (LED) optically coupled to a phototransistor, housed in a compact half-pitch mini-flat 4-pin package. This configuration ensures high current transfer ratio at very low input current and provides excellent electrical isolation with a rated input-output isolation voltage of 3750 VACRMS.
