Product details
Overview
MMBZ15VAL from Nexperia is a low-capacitance unidirectional double ESD protection diode in SOT23 package, configured as common-anode dual cathodes for simultaneous protection of two signal lines against ESD transients up to 30 kV (contact discharge), with 12 V reverse standoff voltage, ≤105 pF capacitance, and 40 W peak pulse power - used in high-speed USB and audio data line protection.
For engineers reviewing the MMBZ15VAL datasheet, MMBZ15VAL pinout, MMBZ15VAL application, or MMBZ15VAL equivalent, key selection criteria include bidirectional/single-line vs. unidirectional/dual-line protection mode, clamping voltage under 1.9 A IPPM, ultra-low 5 nA leakage at 12 V, and SOT23 footprint compatibility with high-density portable PCB layouts.
Technical Context
This device implements a common-anode dual-diode topology enabling either unidirectional protection of two independent signal-to-ground paths (pins 1–3 and 2–3) or bidirectional protection of one differential or AC-coupled line (pins 1–2). Its IEC 61000-4-2 Level 4 compliance and 30 kV contact ESD rating are achieved via optimized junction design and low-inductance SOT23 layout.
Clamping occurs at ≤21 V under 1.9 A 10/1000 µs surge (IEC 61643-321), with breakdown voltage tightly specified at 14.25–15.75 V (1 mA test current). Thermal resistance to ambient is 460 K/W, requiring careful PCB copper area allocation for sustained pulse handling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 12 V - maximum continuous operating voltage before leakage rises significantly; sets upper limit for protected line DC bias. |
| Breakdown Voltage | 15 V (typ) - voltage at which diode enters avalanche conduction; defines onset of transient clamping action. |
| Clamping Voltage | 21 V (max at 1.9 A) - maximum voltage seen by protected circuit during worst-case 10/1000 µs surge; critical for IC I/O survival. |
| Diode Capacitance | 85–105 pF at 1 MHz - low enough for USB 2.0 (480 Mbps) and audio interfaces without signal integrity degradation. |
| Peak Pulse Power | 40 W - energy-handling capability for standardized ESD/surge waveforms; enables robust front-end protection. |
| ESD Rating | 30 kV contact discharge - exceeds IEC 61000-4-2 Level 4; qualifies for handheld device button, port, and touchscreen interface protection. |
| Leakage Current | 5 nA max at 12 V - negligible loading on high-impedance sensor or reference lines; preserves battery life in portable devices. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 3-terminal, 1.9 mm pitch, 2.9 × 1.3 × 1.0 mm body, standard footprint per Fig. 10 (reflow) and Fig. 11 (wave).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Diode 1) | Connects to first signal line requiring unidirectional ESD protection to ground (pin 3); anode-shared configuration. |
| 2 | Cathode (Diode 2) | Connects to second independent signal line; enables dual-line protection without discrete components. |
| 3 | Common Anode | Connected to system ground; serves as shared return path for both protection diodes; must be low-inductance. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-line unidirectional protection | Single SOT23 device replaces two discrete TVS diodes - saves board space and reduces BOM count in multi-signal interfaces. |
| Bidirectional single-line mode | Pins 1 and 2 used differentially (e.g., USB D+/D−) with pin 3 grounded - provides symmetrical ±21 V clamping for AC-coupled signals. |
| Low 85 pF typical capacitance | Preserves signal rise/fall times in 480 Mbps USB 2.0 and 24-bit audio I²S buses without measurable jitter or attenuation. |
| 40 W rated peak pulse power | Handles repeated 10/1000 µs surges per IEC 61643-321 - suitable for industrial docking stations and peripheral hubs. |
| 30 kV contact ESD immunity | Validated for direct human touch events on exposed connectors and buttons - meets EN 61000-4-2 for Class A/B equipment. |
Applications
| USB 2.0 Data Lines | Smartphone Audio Jack |

IC Role / Device Role: Unidirectional clamp per line (pins 1–3 and 2–3), with fast response to ESD events from operator finger contact. Use Value: 5 nA leakage prevents I²C pull-up current error; 12 V VRWM matches 3.3 V logic rail with 20% margin for noise spikes. | Use Scenario: ESD safeguard for momentary push-button inputs (volume up/down, play/pause) on Bluetooth earbud charging case PCB. IC Role / Device Role: Single-device dual-line protection of two independent GPIO lines, each referenced to system ground. Use Value: SOT23 footprint fits tight 5 mm × 5 mm button layout; 30 kV rating withstands repeated pocket insertion/removal discharges. |
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 | Same SOT23-3, 12 V VRWM, but higher 150 pF capacitance and 25 V clamping at 1.9 A. | Less suitable for >100 Mbps data lines due to higher capacitance; better for lower-speed GPIO or power rails. | Select when cost sensitivity outweighs signal integrity needs and clamping voltage margin is acceptable. |
| Vishay ESDE0402-12 | 0402 chip-scale package (0.6 × 0.3 mm), 12 V VRWM, 100 pF, but rated only for 20 W PPPM and 15 kV ESD. | Enables ultra-compact placement at connector entry point but lacks MMBZ15VAL's 30 kV robustness for handheld use. | Choose for space-constrained wearables where 15 kV ESD suffices and thermal derating is managed. |
Compared with NUP4202MR6T1G and ESDE0402-12, MMBZ15VAL delivers superior high-speed signal integrity (85 pF), highest ESD robustness (30 kV), and balanced clamping (21 V), making it optimal for USB/audio interfaces where both speed and ruggedness are required.

FAQ
What is the maximum recommended PCB trace length between MMBZ15VAL and the protected connector?
Per Nexperia application guidance (Fig. 8), the device must be placed within 2 mm of the protected input terminal or connector. Longer traces increase inductance, degrading clamping performance during sub-nanosecond ESD events - verified by 30 kV testing with <1 cm path length to ground.
Can MMBZ15VAL protect bidirectional data lines like RS-485 or CAN?
No - MMBZ15VAL is not rated for RS-485 or CAN bus protection. Its 12 V VRWM and 21 V clamping are insufficient for ±7 V or ±12 V common-mode ranges; dedicated bidirectional TVS arrays (e.g., PESD5V0S1BA) are required for such protocols.
Does MMBZ15VAL require external series impedance for optimal ESD performance?
No external resistor is needed. The diode's low dynamic resistance (<1 Ω during clamping) and integrated common-anode structure provide effective transient shunting directly to ground. Adding series resistance would delay response and raise clamped voltage beyond 21 V.
Is MMBZ15VAL qualified for automotive applications?
No - this variant is non-automotive qualified (per Revision History, Section 14). For automotive use, Nexperia offers the -Q qualified MMBZ15VAL-Q version, which undergoes AEC-Q101 stress testing and supports extended temperature range (−40 °C to +125 °C).
