Zener voltage regulator diodes
General-purpose Zener diodes in a SOD323 (SC-76) very small Surface-Mounted Device (SMD) plastic package.
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]

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.
