SFH691AT - Optocoupler

General Description

The SFH691AT has a GaAs infrared emitting diode emitter, which is optically coupled to silicon planar phototransistor detector, and is incorporated in a 4 pin 100 mil lead pitch miniflat package.

Key Features

  • a high current transfer ratio, low coupling capacitance, and high isolation voltage. The coupling devices are designed for signal transmission between two electrically separated circuits.
