BAS31

General purpose controlled avalanche (double) diodes

General purpose switching diodes fabricated in planar technology, and encapsulated in small rectangular plastic SMD SOT23 packages. The BAS29 consists of a single diode. The BAS31 has two diodes in series. The BAS35 has two diodes with a common anode.

Features and benefits

  • Small plastic SMD package

  • Switching speed: max. 50 ns

  • General application

  • Continuous reverse voltage: max. 90 V

  • Repetitive peak reverse voltage: max. 110 V

  • Repetitive peak forward current: max. 600 mA

  • Repetitive peak reverse current: max. 600 mA.

  • AEC-Q101 qualified

Applications

  • General purpose switching in e.g. surface mounted circuits.

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.
