PZU4.3B

Zener voltage regulator diodes in a SOD323F package

General-purpose Zener diodes in a SOD323F (SC-90) very small and flat lead Surface Mounted Device (SMD) plastic package.

Features and benefits

  • Total power dissipation: 550 mW

  • Tolerance series: B: approximately 5 %; B1, B2, B3: sequential, approximately 2 %

  • Small plastic package suitable for surface mounted design

  • Wide working voltage range: nominal 2.4 V to 51 V

  • Very low leakage current for a given reverse voltage for types PZU5.1B - PZU10B

  • PZU5.1B2 - 10B: Very low dynamic impedances at low currents, very low leakage current, hard breakdown knee

  • PZU11B2 - 51B: Intentional minor rise of leakage current for optimized fast switching and noise reduction [Ref. AN90031]

  • AEC-Q101 qualified

Applications

  • General regulation functions

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.
