Features

  • Glass passivated junction.
  • 1500W Peak Pulse Power capability at 1.0 ms.
  • Excellent clamping capability.
  • Low incremental surge resistance.
  • Fast response time; typically less than 1.0 ps from 0 volts to BV for unidirectional and 5.0 ns for bidirectional.
  • Typical IR less than 1.0 µA above 10V. DEVICES FOR BIPOLAR APPLICATIONS - Bidirectional types use CA suffix. - Electrical Characteristics apply in both directions. DO-201AE COLOR BAND DENOTES CATHODE *These ratings are limiting values above which the serviceability of any semiconductor device may be impaired.
