DESCRIPTION
The SFH690ABT, SFH690AT, SFH690BT, SFH690CT,
SFH690DT 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 SFH690
series is available only on tape and reel. There are
2000 parts per reel. Marking for SFH690AT is 690A;
SFH690BT is 690B; SFH690CT is 690C; SFH690DT is 690D;
SFH690ABT will be marked as 690A or 690B.
