Overview
The Nexperia MMBZ6V2AT-QR is a low capacitance unidirectional double ESD protection diode in a common anode configuration, encapsulated in a SOT23 (TO-236AB) small Surface-Mounted Device plastic package. Designed for ESD and transient overvoltage protection of up to two signal lines, it features a reverse stand-off voltage of 3 V and an ultra-low leakage current below 1 nA. The device provides bidirectional ESD protection for one line or unidirectional protection for two lines, with clamping voltages reaching 12 V at peak pulse currents of 8.8 A.
Feature Summary
- Unidirectional ESD protection capability for two independent signal lines
- Bidirectional ESD protection capability for a single signal line
- Ultra-low leakage current performance under rated reverse voltage conditions
- Qualified according to AEC-Q101 standards for automotive applications
Applications
- Computers and peripherals
- Automotive electronic control units
- Cellular handsets and accessories
- Audio and video equipment
- Portable electronics
Procurement Notes
Verify the specific suffix 'QR' against official Nexperia documentation to confirm reel packaging specifications and ensure compliance with regional RoHS directives. Confirm that the AEC-Q101 qualification status aligns with target automotive reliability requirements before finalizing procurement orders.
Selection Notes
Select this component when protecting dual signal lines requiring unidirectional clamping within a compact SOT23 footprint. Ensure the application operates within the specified -55 °C to 150 °C ambient temperature range and respects the 17 W peak pulse power rating during surge events.
Part Context
This part belongs to Nexperia's family of low capacitance ESD protection devices designed for high-speed data lines. It utilizes a monolithic structure to provide robust transient suppression while maintaining signal integrity through minimal parasitic capacitance effects on protected interfaces.
Replacement Considerations
Verify pinout compatibility and electrical parameters against existing designs. Check if alternative Nexperia parts like MMBZ9V1AL offer similar protection levels with different capacitance profiles.
