Alternatives

Features and benefits

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

  • Total power dissipation: Ptot ≤ 320 mW

  • Tolerance series:

    • B: approximately ±5 %

    • B1, B2, B3: approximately ±2 %

  • Wide working voltage range: nominal 2.4 V to 51 V (E24 range)

  • Low reverse current IR range

  • Small plastic package suitable for surface-mounted design

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

  • PZU11B2A-51BA: Intentional minor rise of leakage current for optimized fast switching and noise reduction [Ref. AN90031]

Applications

  • General regulation functions

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.
