DESCRIPTION
The SFH690xT family has a GaAs infrared emitting diode
emitter, which is optically coupled to a silicon planar phototransistor
detector, and is incorporated in a 4 pin 100
mil lead pitch miniflat package. It 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.
The SFH690xT will be offered in tape and reel format
only. There are 2000 parts per reel. For the SFH690AT,
the product will be marked as SFH690A and the
SFH690BT will be marked as SFH690B. The
SFH690ABT will be marked as SFH690A or SFH690B.
