BAS21J-Q

Single high-speed switching diode

High-speed switching diode, encapsulated in a SOD323F (SC-90) very small and flat lead Surface-Mounted Device (SMD) plastic package.

Features and benefits

  • High switching speed: trr ≤ 50 ns

  • Low capacitance: Cd ≤2 pF

  • Low leakage current

  • Reverse voltage: VR ≤ 300 V

  • Repetitive peak reverse voltage: VRRM ≤ 300 V

  • Very small and flat lead SMD plastic package

  • Excellent coplanarity and improved thermal behavior

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

Applications

  • High-speed switching

  • Voltage clamping

  • General-purpose switching

  • Reverse polarity protection

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.
