Description

In the OptoHiT™ series, the FODM8801 is a first-of-kind phototransistor, utilizing Fairchild’s leading-edge proprietary process technology to achieve high operating temperature characteristics, up to 125°C. The opto coupler consists of an aluminum gallium arsenide (AlGaAs) infrared light-emitting diode (LED) optically coupled to a phototransistor, available 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.
