Voltage regulator diodes

Low-power voltage regulator diodes in hermetically sealed leaded glass SOD27 (DO-35) packages. The diodes are available in the normalized E24 +- 2 pct. (BZX79-B) and approx. +- 5 pct. (BZX79-C) tolerance range. The series consists of 37 types with nominal working voltages from 2.4 to 75 V.


  • Total power dissipation: max. 500 mW
  • Two tolerance series: +- 2pct. , and approx. +- 5pct.
  • Working voltage range: nom. 2.4 to 75 V (E24 range)
  • Non-repetitive peak reverse power dissipation: max. 40 W.

Target applications

  • Low voltage stabilizers or voltage references.
