SFH690BT Description

Short technical summary and product information.

The SFH690BT is an optocoupler designed for reliable signal transmission between electrically separated circuits. It features a GaAs infrared emitting diode coupled to a silicon planar phototransistor detector.

 

Key electrical specifications include a high collector emitter breakdown voltage of 70V and an isolation test voltage of 3750V RMS. The device operates with a typical forward current of 50mA and a maximum collector current of 100mA, offering a typical current transfer ratio of 300%.

 

This optocoupler is packaged in a space-saving SOP-4 (small outline package) with a 100 mil (2.54 mm) lead pitch, making it suitable for high-density mounting or space-sensitive PCBs. It is supplied on tape and reel, with 2000 units per reel.

 

Applications include signal transmission in PLCs and telecommunication systems where electrical isolation is critical.
