BZX79-B12

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.

Features and benefits

  • 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.

Applications

  • Low voltage stabilizers or voltage references.

Sample

As a Nexperia customer you can order samples via our sales organization.

If you do not have a direct account with Nexperia our network of global and regional distributors is available and equipped to support you with Nexperia samples. Check out the list of official distributors.

How does it work?

The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
