MMBZ33VAT-Q

Low capacitance unidirectional double ESD protection diode

Unidirectional double ElectroStatic Discharge (ESD) protection diode in a common anode configuration, encapsulated in a SOT23 (TO-236AB) small Surface-Mounted Device (SMD) plastic package. The device is designed for ESD and transient overvoltage protection of up to two signal lines.

Features and benefits

  • Unidirectional ESD protection of two lines

  • Bidirectional ESD protection of one line

  • Very low diode capacitance: Cd ≤ 25 pF

  • Reverse stand-off voltage: VRWM = 26 V

  • Low clamping voltage: VCL = 49 V typ. at IPP = 2.8 A

  • ESD protection up to 20 kV (IEC 61000-4-2)

  • Ultra low leakage current: IRM < 1 nA

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

Applications

  • Computers and peripherals

  • Audio and video equipment

  • Cellular handsets and accessories

  • Automotive electronic control units

  • 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.
