Overview
The FODM8801A, part of the OptoHiT series from onsemi, is a cutting-edge phototransistor optocoupler designed to operate at high temperatures up to 125°C. This device utilizes onsemi's proprietary process technology to achieve superior performance. 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 (CTR) at very low input currents and its high input-output isolation voltage of 3750 VACRMS.
