Voltage regulator diodes

Medium-power voltage regulator diodes in a SOT89 plastic SMD package.

The diodes are available in the normalized E24 approx. +-5pct tolerance range. The series consists of 37 types with nominal working voltages from 2.4 to 75 V (BZV49-C2V4 to BZV49-C75).


  • Total power dissipation: max. 1 W
  • Tolerance series: approx. +-5pct
  • Working voltage range: nom. 2.4 to 75 V (E24 range)
  • Non-repetitive peak reverse power dissipation: max. 40 W.
  • AEC-Q101 qualified

Target applications

  • General regulation functions.
