OPI120 - Optically Coupled Isolator

General Description

Each Optoisolator in this data sheet contains an infrared Light Emitting Diode (LED) and a NPN silicon Photosensor.

The OPI120 has an 890 nm Light Emitting Diode (LED) and NPN phototransistor sensor, whereas the OP123 has a 890 nm LED and a photodarlington sensor.

Key Features

  • 15 kV dc electrical isolation.
  • Choice of phototransistor or photodarlington output.
  • Hermetically sealed LED and photosensor.
  • Base contact for conventional transistor biasing (OP120 only).
  • UL recognized File No. E58730.
  • Wide operating temperature range.
