Voltage regulator diodes

Low-power voltage regulator diodes in a small SOD323 (SC-76) Surface-Mounted Device (SMD) plastic package.

The diodes are available in the normalized E24 ±1 % (BZX384-A), ±2 % (BZX384-B) and approximately ±5 % (BZX384-C) tolerance range. The series includes 37 breakdown voltages with nominal working voltages from 2.4 V to 75 V.

Features and benefits

  • Total power dissipation: ≤300 mW

  • Three tolerance series: ±1 %, ±2 % and approximately ±5 %

  • Working voltage range: nominal 2.4 V to 75 V (E24 range)

  • Non-repetitive peak reverse power dissipation: ≤ 40 W

  • Qualified according to AEC-Q101 and recommended for use in automotive applications


  • General regulation functions

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.
