onsemi FOD8802 OptoHiT™ Phototransistor Optocouplers

onsemi FOD8802 OptoHiT™ Phototransistor Optocouplers utilize onsemi's leading-edge proprietary process technology. This achieves a high operating temperature performance of up to 125°C. The optocouplers consist of two aluminum gallium arsenide (AlGaAs) infrared light-emitting diodes optically coupled to two phototransistors. They are housed in a small outline, 8-pin SOIC package. The devices deliver a consistent current transfer ratio at a very low input current over temperature.

Features

  • Excellent CTR linearity at high temperature
  • CTR at very low Input Current, IF
  • High isolation voltage regulated by Safety Agency, UL1577, 2500 VAC RMS for 1 min
  • Applicable to Infrared Ray reflow, 260°C
  • These are Pb-free devices

Applications

  • Primarily suited for DC−DC converters
  • For ground loop isolation, signal to noise isolation
  • Communications adapters, chargers
  • Consumer appliances, set-top boxes
  • Industrial power supplies, motor control, programmable logic control
