High-speed double diode

The BAS28 consists of two high-speed switching diodes, fabricated in planar technology, and encapsulated in the small plastic SMD SOT143 package. The diodes are not connected.


  • Small plastic SMD package
  • High switching speed: max. 4 ns
  • Continuous reverse voltage: max. 75 V
  • Repetitive peak reverse voltage: max. 85 V
  • Repetitive peak forward current: max. 500 mA .
  • AEC-Q101 qualified

Target applications

  • High-speed switching in e.g. surface mounted circuits.
