Product details
Overview
MMBZ6V2AL from Nexperia is a unidirectional double ESD protection diode in common-anode SOT23 configuration, designed for transient overvoltage protection of two signal lines. It delivers 30 kV contact ESD immunity (IEC 61000-4-2 Level 4), 24 W peak pulse power, and ultra-low 175–230 pF capacitance - enabling high-speed USB 2.0 and HDMI interface protection in portable electronics.
For engineers reviewing the MMBZ6V2AL datasheet, MMBZ6V2AL pinout, MMBZ6V2AL application, or MMBZ6V2AL equivalent, key selection criteria include reverse standoff voltage (3 V), clamping voltage (8.7 V at 2.76 A), low leakage (200 nA), and AEC-Q101 qualification for automotive ECU designs.
Technical Context
This device implements a dual-cathode, single-common-anode topology to support either unidirectional protection of two independent lines (e.g., D+ and D−) or bidirectional protection of one line via series-connected cathodes. Its low 175 pF typical capacitance minimizes signal distortion on high-frequency data paths up to 480 Mbps.
The 6.2 V nominal breakdown voltage (VBR) and 8.7 V clamping voltage (VCL) at IPPM = 2.76 A ensure robust transient suppression while maintaining compatibility with 3.3 V logic rails. Thermal resistance Rth(j-a) is 460 K/W in free air, supporting operation across −55 °C to +150 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 3 V - Maximum continuous working voltage before conduction; ensures no interference with 3.3 V signal integrity during normal operation. |
| Breakdown Voltage | 6.2 V (typ) - Trigger point for avalanche conduction; enables precise ESD response without premature turn-on. |
| Clamping Voltage | 8.7 V at 2.76 A - Peak voltage seen by protected IC during 10/1000 µs surge; limits stress on downstream 3.3 V transceivers. |
| Diode Capacitance | 175 pF (typ) at 1 MHz - Low enough to avoid signal attenuation or timing skew on USB 2.0 or audio I²S lines. |
| Peak Pulse Power | 24 W - Sustains IEC 61643-321-compliant surges without degradation; validated per 10/1000 µs waveform. |
| ESD Rating | 30 kV contact discharge - Meets IEC 61000-4-2 Level 4; protects against human-body-model discharges in handheld devices. |
| Leakage Current | 200 nA max at 3 V - Prevents DC loading on high-impedance sensor or analog input circuits. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 3-terminal, 1.9 mm pitch, 2.9 mm × 1.3 mm × 1.0 mm body; optimized for automated placement and reflow soldering on FR4 PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K1) | Cathode 1 | Connects to first protected signal line (e.g., USB D+); conducts ESD current to common anode when line voltage exceeds 3 V. |
| 2 (K2) | Cathode 2 | Connects to second protected signal line (e.g., USB D−); operates independently but shares anode return path. |
| 3 (A) | Common Anode | Connected to system ground; provides single-point surge return path for both cathodes - simplifies PCB layout and reduces loop inductance. |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional dual-line protection | Enables simultaneous safeguarding of two independent 3.3 V data lines (e.g., HDMI TMDS pairs) without cross-talk or shared impedance. |
| Bidirectional single-line mode | Supports high-voltage transient suppression on one AC-coupled line (e.g., audio jack) by connecting cathodes in series between line and ground. |
| AEC-Q101 qualification | Validated for automotive ECU environments including temperature cycling, humidity bias, and mechanical shock - suitable for infotainment and ADAS interfaces. |
| Low thermal resistance | Rth(j-sp) = 150 K/W to solder point - facilitates rapid heat dissipation during repetitive ESD events on densely populated PCBs. |
| Standard SOT23 footprint | Compatible with industry-standard pick-and-place equipment and IPC-7351B land patterns - eliminates custom stencil or placement tooling. |
Applications
| USB 2.0 Interface Protection | HDMI TMDS Line Protection |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NUP4201MR6T1G | Higher 12 V clamping voltage (at 1 A), 30 pF lower capacitance (145 pF typ), bidirectional-only dual-diode architecture. | Requires separate ground return for each line; unsuitable for common-anode routing constraints in space-constrained layouts. | Select when lowest possible capacitance is critical and board layout allows independent grounding. |
| Vishay ESDE0402-3.3 | 3.3 V standoff, 12 pF capacitance, 12 kV ESD rating - optimized for RF front-end protection, not automotive-grade reliability. | Lacks AEC-Q101 qualification and fails IEC 61000-4-2 Level 4; limited to consumer-grade portable devices only. | Choose only for cost-sensitive non-automotive applications where ESD threat level is ≤15 kV. |
Compared with NUP4201MR6T1G and ESDE0402-3.3, MMBZ6V2AL uniquely balances automotive qualification, common-anode flexibility, and 30 kV ESD immunity - making it the preferred choice for dual-line protection in safety-critical ECUs and high-reliability portable systems.

FAQ
What is the maximum recommended PCB trace length between MMBZ6V2AL and the protected connector?
For optimal ESD performance, place MMBZ6V2AL within 3 mm of the connector pin. Longer traces increase inductance, raising clamped voltage during fast transients. The device's common-anode layout further demands short, symmetric paths from pins 1 and 2 to the protected lines and a direct low-inductance connection from pin 3 to chassis ground.
Can MMBZ6V2AL protect bidirectional data lines like I²C or SPI?
No - MMBZ6V2AL is unidirectional and requires the protected line to remain positive relative to ground. For bidirectional buses, use two devices in back-to-back configuration or select a dedicated bidirectional ESD array. Its common-anode structure does not support symmetrical clamping across positive/negative voltage excursions.
Does MMBZ6V2AL require external series resistance for USB 2.0 protection?
No external resistor is required. Its 3 V reverse standoff voltage and 8.7 V clamping voltage align with USB 2.0 electrical specifications. Adding series resistance would degrade signal rise/fall times and violate USB eye diagram requirements; layout optimization (short traces, ground plane) suffices for compliance.
How does thermal derating affect MMBZ6V2AL's 24 W peak pulse power rating?
The 24 W rating applies at Tj = 25 °C. Above this, power must be reduced per Fig. 4: at 100 °C junction temperature, rated peak pulse power drops to ~65% (≈15.6 W). Ensure adequate copper area under pin 3 and maintain ambient below 85 °C for sustained surge duty cycles.
