Product details
Overview
MMBZ6V8AL from Nexperia is a low-capacitance 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 ≤200 pF capacitance at 1 MHz, enabling high-speed data line protection in portable electronics.
For engineers reviewing the MMBZ6V8AL datasheet, MMBZ6V8AL pinout, MMBZ6V8AL application, or MMBZ6V8AL equivalent, key selection criteria include its dual-line unidirectional clamping capability, ultra-low leakage (≤300 nA at 4.5 V), AEC-Q101 qualification for automotive ECUs, and validated performance under IEC 61643-321 surge waveforms.
Technical Context
This device implements a common-anode dual-cathode topology, allowing independent unidirectional protection of two separate signal paths to ground while supporting bidirectional protection of a single line via differential operation between K1 and K2. Its junction breakdown voltage is tightly specified at 6.46–7.14 V (1 mA), with clamping voltage limited to 9.6 V at 2.5 A (10/1000 µs).
Thermal resistance from junction to ambient is 460 K/W in free air, and its 150 °C maximum junction temperature supports operation in automotive under-hood environments. The SOT23 package enables compact PCB layout with minimal parasitic inductance-critical for preserving ESD response time and signal integrity on high-frequency interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 4.5 V - Maximum continuous operating voltage before conduction; sets safe margin below system supply rails. |
| Breakdown Voltage | 6.8 V (typ) at 1 mA - Precise turn-on threshold ensures reliable clamping without false triggering. |
| Clamping Voltage | 9.6 V at 2.5 A (10/1000 µs) - Limits transient voltage seen by downstream ICs during surge events. |
| Diode Capacitance | 150 pF (typ) at 1 MHz, 0 V - Enables use on USB 2.0, HDMI, and audio lines without signal degradation. |
| Peak Pulse Power | 24 W - Sustains IEC 61000-4-2 and IEC 61643-321 transients without failure. |
| ESD Rating | 30 kV contact discharge - Meets highest industrial and automotive ESD immunity requirements. |
| Leakage Current | 300 nA max at 4.5 V - Minimizes standby power loss and avoids interference with high-impedance sensor inputs. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 3-terminal, 2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm lead pitch, optimized for automated assembly and high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K1) | Cathode 1 | Protected signal line 1 anode connection point; conducts ESD current to common anode (pin 3) during positive transients. |
| 2 (K2) | Cathode 2 | Protected signal line 2 anode connection point; enables independent clamping of second data line. |
| 3 (A) | Common Anode | Shared ground reference terminal; routes transient energy from either cathode to system ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Common-anode dual-cathode architecture | Enables simultaneous protection of two unidirectional signal lines with single-component footprint savings. |

| 2.5 A peak pulse current rating | Supports robust protection against IEC 61000-4-2 and ISO 10605 surges without thermal runaway. |
| 300 nA reverse leakage (max) | Prevents DC loading on precision analog inputs and battery-powered sensor nodes. |
Applications
| USB 2.0 Data Lines | Automotive Infotainment Interfaces |
|---|---|
|

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 NZM3301A | Higher capacitance (350 pF typ), lower ESD rating (15 kV contact), same SOT23-3 package and common-anode topology. | Better suited for cost-sensitive consumer peripherals where bandwidth is not critical. | Select when budget constraints outweigh high-speed signal integrity requirements. |
| Vishay VEML6030X01 | Photodiode with integrated ESD protection-not a dedicated TVS-lacks defined clamping voltage or PPPM rating. | Only applicable as secondary protection in optical sensing circuits, not primary data-line suppression. | Not a functional substitute; avoid for ESD-critical signal line protection roles. |
Compared with NZM3301A and VEML6030X01, MMBZ6V8AL provides superior high-frequency performance (150 pF vs. 350 pF), higher ESD immunity (30 kV vs. 15 kV), and verified clamping behavior-making it the preferred choice for automotive and high-speed interface protection where signal fidelity and reliability are non-negotiable.

FAQ
What is the maximum recommended PCB trace length between MMBZ6V8AL and protected signal lines?
For optimal ESD performance, place MMBZ6V8AL within 2 mm of the connector or IC pin being protected. Longer traces increase inductance, raising clamping voltage during fast transients-verified by IEC 61000-4-2 testing with 100 ps rise times. Ground return path must be direct and low-inductance, using multiple vias to internal ground planes.
Can MMBZ6V8AL protect bidirectional data lines like I²C or SPI?
Yes-when used between SDA/SCL and ground, MMBZ6V8AL provides bidirectional protection of a single line via differential conduction between K1 and K2. Its 4.5 V standoff and 9.6 V clamping ensure compatibility with 3.3 V and 5 V logic levels without interfering with normal bus signaling or pull-up resistor operation.
Is MMBZ6V8AL compatible with lead-free reflow soldering profiles?
Yes-MMBZ6V8AL is qualified for standard JEDEC J-STD-020 lead-free reflow, with peak temperature tolerance up to 260 °C. The SOT23 package uses matte tin plating and meets IPC/JEDEC standards for wetting balance and intermetallic formation, ensuring reliable solder joint integrity in high-volume manufacturing.
How does thermal resistance affect MMBZ6V8AL's surge handling in enclosed automotive modules?
With Rth(j-a) = 460 K/W in free air, sustained surge events require careful PCB thermal design: use ≥1 cm² copper pour under pin 3 (anode), add thermal vias to inner ground layers, and limit ambient temperature to ≤105 °C to maintain junction temperature below 150 °C during repeated 2.5 A pulses per IEC 61643-321.
