BZX8450-B43-Q

Low-current voltage regulator diodes

Low-current voltage regulator diodes in a small SOT23 Surface-Mounted Device (SMD) plastic package.

Features and benefits

  • Total power dissipation: ≤ 250 mW

  • Two tolerance series: ± 2 % and approximately ± 5 %

  • Working voltage range: nominal 1.8 V to 51 V

  • Specified at a low test current (50 μA), ideal for low bias and portable battery-powered applications

  • BZX8450-B11-Q to -C51-Q: Intentional minor rise of leakage current for optimized fast switching and noise reduction [AN90031]

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

Applications

  • Low-current 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.
