Phototransistor Optocouplers

Realize increased design margins and stable parameters in high temperature environments with ON Semiconductor's new FODM8801 OptoHiT™ high temperature phototransistor optocoupler. Achieve high noise immunity and reliable isolation at high operating temperatures, up to 125°C, as this new series implements ON Semiconductor's proprietary OPTOPLANAR® coplanar packaging technology. In addition, the FODM8801 offers excellent CTR linearity and operates at a very low input current (IF). The optocoupler consists of an aluminum gallium arsenide (AlGaAs) infrared light emitting diode optically coupled to a phototransistor.

Because the FODM8801 is packaged in a compact, half-pitch, mini-flat, 4-pin package (1.27mm lead pitch), benefits also include board space savings and design flexibility, ultimately allowing for overall reductions in system cost.
