FODM8801B: OptoHiT™ Series, High-Temperature Phototransistor

The OptoHiT™ FODM8801 is a first-of-its-kind phototransistor, utilizing Fairchild’s leading-edge, 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, in a compact half pitch, mini-flat, 4-pin package. It delivers high current transfer ratio at very low input current. The input-output isolation voltage, VISO, is rated at 3750 VACRMS.
