Product details
Overview
MMBZ10VAL-Q 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), 14.2 V clamping voltage at 1.7 A, and ultra-low 130–170 pF capacitance - enabling high-speed data line protection in automotive ECUs and portable electronics.
For engineers reviewing the MMBZ10VAL-Q datasheet, MMBZ10VAL-Q pinout, MMBZ10VAL-Q application, or MMBZ10VAL-Q equivalent, key selection criteria include its dual-line unidirectional topology, 6.5 V reverse standoff voltage, AEC-Q101 qualification, and low-leakage (20 nA) performance under bias.
Technical Context
This device implements a common-anode dual-cathode structure, allowing independent unidirectional protection of two separate signal paths to ground while supporting bidirectional protection of a single line via differential operation. Its junction design ensures fast response (<1 ns rise time) to ESD pulses per IEC 61000-4-2.
Thermal resistance from junction to solder point is 340 K/W, and it sustains 24 W peak pulse power (10/1000 µs waveform) with clamping limited to 14.2 V - critical for safeguarding 3.3 V and 5 V logic interfaces without rail collapse.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 6.5 V - defines maximum continuous operating voltage before leakage exceeds 1 µA; sets upper limit for protected I/O rails. |
| Clamping Voltage | 14.2 V at 1.7 A - limits transient voltage seen by downstream ICs during 10/1000 µs surge events. |
| Diode Capacitance | 130–170 pF at 1 MHz - low enough for USB 2.0, HDMI, and audio line protection without signal integrity degradation. |
| ESD Rating | 30 kV contact discharge - exceeds IEC 61000-4-2 Level 4, ensuring robustness against human-body ESD events. |
| Peak Pulse Power | 24 W - supports high-energy transients without thermal runaway when mounted on standard FR4 PCB. |
| Leakage Current | 20 nA at 6.5 V - minimizes standby power loss and avoids false triggering in high-impedance sensor or analog front-end circuits. |
Pinout & Package
Encapsulated in a SOT23 (TO-236AB) surface-mount plastic package measuring 2.9 mm × 1.3 mm × 1.0 mm with 1.9 mm lead pitch, the MMBZ10VAL-Q uses a standardized 3-terminal footprint compatible with automated assembly and reflow processes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K1) | Cathode of Diode 1 | Connects to first protected signal line; conducts transient current to common anode (pin 3) during overvoltage. |
| 2 (K2) | Cathode of Diode 2 | Connects to second protected signal line; enables independent ESD clamping for dual-line interfaces. |
| 3 (A) | Common Anode | Connected to system ground; serves as shared return path for both diodes' surge current. |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional dual-line protection | Enables discrete ESD hardening of two independent signal paths (e.g., USB D+ and D−) using one component. |
| AEC-Q101 qualification | Validated for automotive environments including temperature cycling (−55 °C to +150 °C) and humidity exposure. |
| Low capacitance (130–170 pF) | Preserves signal edge rate and bandwidth in high-speed digital interfaces up to 480 Mbps. |
| Ultra-low leakage (20 nA) | Prevents DC loading on precision analog inputs or battery-powered sensor nodes. |
Applications
| Automotive ECU Protection | USB 2.0 Interface 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 capacitance (300 pF), lower clamping voltage (12.5 V), same SOT23-3 package and common-anode topology. | Better for low-voltage 1.8 V systems but unsuitable for >100 Mbps data rates due to higher Cd. | Select when clamping voltage margin is prioritized over bandwidth preservation. |
| Vishay ESDE05C1-2 | Lower standoff (5.0 V), identical 30 kV ESD rating, and 120 pF capacitance; also AEC-Q101 qualified. | Optimized for 5 V USB and HDMI applications where tighter voltage tolerance is required. | Choose for designs needing tighter VRWM matching to 5 V supply rails with minimal capacitance penalty. |
Compared with NUP4201MR6T1G and ESDE05C1-2, the MMBZ10VAL-Q offers the best balance of low capacitance (130–170 pF), 6.5 V standoff, and automotive qualification - making it optimal for dual-line protection in 3.3 V/5 V mixed-signal automotive and portable systems.

FAQ
What is the maximum operating temperature for MMBZ10VAL-Q?
The MMBZ10VAL-Q has a specified junction temperature range of −55 °C to +150 °C and an ambient operating range of −55 °C to +150 °C. Its thermal resistance from junction to solder point is 340 K/W, enabling reliable operation in under-hood automotive environments when properly mounted on FR4 PCB with recommended pad layout.
Can MMBZ10VAL-Q protect bidirectional data lines like RS-485?
Yes - when used with both cathodes (pins 1 and 2) connected to differential signal lines and the common anode (pin 3) grounded, the device provides bidirectional ESD protection for one differential pair. This configuration leverages its inherent symmetry and meets IEC 61000-4-2 Level 4 for both polarities without external components.
Is MMBZ10VAL-Q suitable for USB Type-C connector protection?
No - while MMBZ10VAL-Q supports USB 2.0 speeds, it lacks the channel count and ultra-low capacitance (<10 pF) required for USB Type-C SuperSpeed (5 Gbps+) differential lanes. It is appropriate for legacy USB 2.0 D+/D− lines but not for SS TX/RX or CC pin protection in Type-C implementations.
How does the common-anode configuration affect PCB layout?
The common-anode layout requires grounding pin 3 directly to a low-inductance ground plane, with pins 1 and 2 routed separately to their respective protected signals. Trace lengths must be minimized (<5 mm), and ground vias placed within 2 mm of pin 3 to preserve ESD response speed and avoid impedance discontinuities that degrade clamping performance.
