Product details
Overview
MMBZ5V6AL 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 ≤280 pF capacitance - enabling high-speed data line protection in space-constrained portable electronics.
For engineers reviewing the MMBZ5V6AL datasheet, MMBZ5V6AL pinout, MMBZ5V6AL application, or MMBZ5V6AL equivalent, key selection criteria include its dual-line unidirectional clamping capability, low-leakage (5 µA max at 3 V), AEC-Q101 qualification, and compatibility with USB 2.0, HDMI, and automotive infotainment I/O interfaces.
Technical Context
This device implements a common-anode dual-cathode topology, allowing independent unidirectional protection of two signal paths to ground while supporting bidirectional protection on a single line via differential clamp behavior. Its 5.6 V nominal breakdown voltage (VBR) and 8 V clamping voltage (VCL) at 3 A ensure robust surge suppression without compromising signal integrity.
Thermal resistance from junction to ambient is 460 K/W in free air, and it operates across –55 °C to +150 °C ambient range. The 210–280 pF capacitance at 1 MHz and 0 V bias enables use on high-frequency interfaces up to ~300 MHz without significant signal degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 3 V - maximum continuous operating voltage before conduction begins; defines safe signal swing range for protected lines. |
| Breakdown Voltage | 5.6 V (typ) at 1 mA - precise threshold where avalanche conduction initiates to divert transients. |
| Clamping Voltage | 8 V at 3 A, 10/1000 µs - maximum voltage seen by protected circuit during worst-case surge event. |
| Diode Capacitance | 210–280 pF at 1 MHz, 0 V - low enough to avoid signal distortion on USB 2.0 or audio I²S lines. |
| Peak Pulse Power | 24 W - energy-handling capacity per line under IEC 61643-321 10/1000 µs waveform. |
| ESD Rating | 30 kV contact discharge (IEC 61000-4-2 Level 4) - exceeds industrial and automotive ESD immunity requirements. |
| Leakage Current | 0.24–5 µA at 3 V - ensures minimal DC loading on sensitive analog or low-power sensor inputs. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 3-terminal, 1.9 mm pitch, 2.9 × 1.3 × 1.0 mm body. Optimized for automated placement and reflow soldering on FR4 PCBs with standard footprint (Fig. 11).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K1) | Cathode 1 | Connects to first protected signal line; conducts transient current to common anode (pin 3) during positive overvoltage events. |
| 2 (K2) | Cathode 2 | Connects to second protected signal line; provides independent unidirectional clamping path identical to pin 1. |
| 3 (A) | Common Anode | Connected to system ground; serves as shared return path for both cathodes during ESD/surge events. |
Key Features
| Feature | Design Value |
|---|---|
| Common-anode dual-cathode architecture | Enables compact two-line protection in single SOT23 footprint - reduces board area vs. discrete diode pairs. |
| AEC-Q101 qualification | Validated for automotive ECU applications including infotainment, ADAS sensors, and body control modules. |
| Ultra-low leakage (≤5 µA) | Maintains signal fidelity on battery-powered sensor interfaces and high-impedance analog inputs. |
| 24 W peak pulse power rating | Supports IEC 61000-4-5 surge immunity up to Level 3 (1 kV line-to-ground) when properly laid out. |
| 210–280 pF capacitance | Preserves signal rise time on 480 Mbps USB 2.0 D+/D− lines without requiring series impedance tuning. |
Applications
| USB 2.0 Interface Protection | HDMI CEC Channel Protection |
|---|---|
|

Use Scenario: Safeguarding HDMI Consumer Electronics Control (CEC) bus lines in TV mainboards and set-top boxes. IC Role / Device Role / Timing Role: Dual-line ESD clamp on bidirectional CEC signal (shared pull-up), referenced to chassis ground. Use Value: Enables reliable CEC command transmission after repeated 8 kV air discharge events without communication timeout or reset. |
| Automotive Infotainment I/O | Portable Audio Codec Interface |
|
Use Scenario: Protecting analog audio input/output lines (e.g., AUX-IN, LINE-OUT) in vehicle head units exposed to human-body-model ESD. IC Role / Device Role / Timing Role: Low-capacitance shunt protector on unidirectional audio paths, grounded via common anode to shield plane. Use Value: Eliminates audible pop/click artifacts during ESD events while preserving THD+N <0.01% across 20 Hz–20 kHz bandwidth. |
Use Scenario: Shielding I²S digital audio data and word clock lines between codec and SoC in wireless earbuds and smart speakers. IC Role / Device Role / Timing Role: High-speed ESD clamp on differential clock/data pairs, minimizing inter-pair skew (<5 ps) and jitter accumulation. Use Value: Ensures bit-error-free transmission at 3.072 MHz sample rates even after 30 kV contact discharge applied to adjacent PCB traces. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-line ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NUP4202MR6T1G | Higher capacitance (350 pF typ), lower clamping voltage (6.5 V), same SOT23-3 package. | Better for low-voltage logic (1.8 V I/O) but less suitable for 3.3 V USB due to tighter margin above VRWM. | Select when lower clamping is prioritized over bandwidth preservation; verify layout-induced parasitic inductance does not degrade response. |
| Vishay ESDE05C1-2 | Lower standoff (5 V), higher ESD rating (30 kV air), 120 pF capacitance, SOT23-3 package. | Optimized for 5 V systems with stricter capacitance limits (e.g., MIPI D-PHY), not rated for automotive AEC-Q101. | Prefer for mobile display interfaces; avoid in automotive designs requiring temperature cycling validation. |
Compared with NUP4202MR6T1G and ESDE05C1-2, MMBZ5V6AL uniquely balances 3 V standoff, AEC-Q101 compliance, and sub-280 pF capacitance - making it the only option qualified for dual-line protection in automotive infotainment and industrial USB peripherals requiring extended temperature operation.

FAQ
What is the maximum recommended trace length between MMBZ5V6AL and the protected connector?
For optimal ESD performance, the trace from the protected line to pin 1 or pin 2 must be ≤5 mm, and the ground path from pin 3 to the system ground plane must be direct and ≤3 mm. Longer traces increase inductive impedance, raising clamping voltage during fast transients and risking downstream IC damage.
Can MMBZ5V6AL protect bidirectional data lines like I²C without additional components?
Yes - when used with external pull-up resistors to VCC, MMBZ5V6AL provides bidirectional protection on a single line by clamping both positive and negative transients to ground via its common-anode structure. No series resistors or additional diodes are required for basic I²C SDA/SCL protection at 400 kHz.
Does the 30 kV ESD rating apply to both pins 1 and 2 simultaneously?
No - the 30 kV rating is per pin measured individually from K1 or K2 to the common anode (pin 3). Simultaneous 30 kV stress on both cathodes exceeds thermal limits and may cause permanent parametric shift; system-level testing must follow IEC 61000-4-2 single-pin discharge protocols.
How does thermal resistance affect derating of peak pulse power at elevated ambient temperatures?
At 85 °C ambient, the junction temperature rise during a 10/1000 µs pulse causes PPPM to derate to ~16 W (per Fig. 4). Designers must reduce expected surge repetition rate or add local copper pour to maintain Tj ≤150 °C during sustained transient activity in enclosed automotive enclosures.
