MMBZ33VB-U

Low capacitance bidirectional dual line ESD protection diode

ESD protection device in a small SOT323 (SC-70) Surface-Mounted Device (SMD) plastic package, designed to protect two lines from the damage caused by ElectroStatic Discharge (ESD) and other transients.

Features and benefits

  • Reverse stand-off voltage: VRWM = 27 V

  • Low clamping voltage: VCL = 31 V at IPP = 3.9 A

  • ESD protection up to 30 kV (IEC 61000-4-2)

  • Low capacitance: Cd = 9 pF

  • High temperature capability: Tj = 175 °C

Applications

  • Computers and peripherals

  • Audio and video equipment

  • Cellular handsets and accessories

  • Portable electronics

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.
