SFH620AA, SFH620AGB product information

Optocoupler, Phototransistor Output, AC Input, 5300 VRMS

 SFH620AA, SFH620AGB Datasheet


  • The SFH620AA, SFH620AGB features a high current transfer ratio, low coupling capacitance and high isolation voltage. These couplers have a GaAs infrared emitting diode emitter, which is optically coupled to a silicon planar phototransistor detector,.
  • The coupling devices are designed for signal transmission between two electrically separated circuits.
  • The couplers are end-stackable with 2.54 mm lead spacing. This version complies with IEC 60950 (DIN VDE 0805) for reinforced insulation up to an operation voltage of 400 VRMS or DC.
