Product details
Overview
MMBZ16VAL from Nexperia is a unidirectional double ESD protection diode in common-anode SOT23 (TO-236AB) package, designed for transient overvoltage protection of two signal lines. It delivers 13 V reverse standoff voltage, 19.5–23 V clamping voltage at 1.7 A (10/1000 µs), and 30 kV IEC 61000-4-2 ESD immunity-used in automotive in-vehicle networks to safeguard CAN or LIN bus lines against electrostatic discharge.
For engineers reviewing the MMBZ16VAL datasheet, MMBZ16VAL pinout, MMBZ16VAL application, or MMBZ16VAL equivalent, key selection criteria include its dual-cathode common-anode topology, low 0.1 nA leakage at 13 V, 76–95 pF capacitance at 0 V, AEC-Q101 qualification, and 1.9 A rated peak pulse current under 10/1000 µs waveform.
Technical Context
This device implements a dual-unidirectional TVS structure with shared anode (Pin 3) and independent cathodes (Pins 1 and 2), enabling simultaneous protection of two separate signal paths referenced to common ground. Its VBR = 15.2–16.8 V (IR = 1 mA) ensures reliable turn-on before system-level damage occurs during ESD events.
Clamping performance is characterized under standardized transients: VCL = 23–28 V at 11 A (8/20 µs, IEC 61000-4-5) and 19.5–23 V at 1.7 A (10/1000 µs, IEC 61643-321), with ESD robustness validated to ±30 kV contact/air discharge per IEC 61000-4-2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 13 V - Maximum continuous working voltage before conduction begins; defines safe operating margin for protected signal lines. |
| Breakdown Voltage | 15.2–16.8 V @ 1 mA - Confirmed turn-on threshold ensuring early clamping during fast transients. |
| Clamping Voltage | 19.5–23 V @ 1.7 A (10/1000 µs) - Peak voltage seen by protected IC during surge; critical for downstream IC survival. |
| Peak Pulse Current | 1.9 A (10/1000 µs); 11 A (8/20 µs) - Surge-handling capability aligned with IEC 61643-321 and IEC 61000-4-5 standards. |
| ESD Withstand | ±30 kV (IEC 61000-4-2, contact/air) - Validated immunity level for human-body-model-like discharges. |
| Diode Capacitance | 76–95 pF @ 1 MHz, 0 V - Low enough for high-speed data lines (e.g., LIN, low-speed CAN) without signal integrity degradation. |
| Leakage Current | 0.1 nA typical @ 13 V - Negligible DC loading on sensitive analog or low-power signal paths. |
Pinout & Package
Supplied in TO-236AB (SOT23) plastic surface-mount package: 3-terminal, 1.9 mm pitch, 2.9 × 1.3 × 1.0 mm body size, optimized for automated assembly and space-constrained PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (Cathode 1) | Connects to first signal line requiring unidirectional ESD protection; conducts surge current to common anode when line voltage exceeds VBR. |
| 2 | K2 (Cathode 2) | Connects to second independent signal line; enables dual-line protection without cross-coupling. |
| 3 | A (Common Anode) | Shared return path to ground or power rail; must be routed with low-inductance connection to maintain clamping effectiveness. |
Key Features
| Feature | Design Value |
|---|---|
| Common-anode dual-cathode topology | Enables compact, symmetrical layout for two independent signal lines sharing one ground reference-reducing board area vs. discrete diodes. |
| AEC-Q101 qualification | Validated reliability for automotive environments including temperature cycling, humidity, and mechanical shock-required for in-vehicle network deployment. |
| Low 0.1 nA leakage | Prevents signal distortion or battery drain in always-on automotive modules such as body control units or sensor interfaces. |
| 76–95 pF capacitance | Preserves signal rise/fall times on LIN bus (up to 20 kbps) and low-speed CAN (125 kbps), avoiding timing skew or false triggering. |
Applications
| Automotive LIN Bus Protection | Industrial RS-485 Interface |
|---|---|
Use Scenario: Protecting LIN transceiver pins (LIN_H/L) in door modules or seat controllers against ESD during service or assembly. IC Role / Device Role / Timing Role: Unidirectional TVS clamp limiting transient voltage to ≤23 V during ±8 kV contact discharge, preserving transceiver integrity. Use Value: Prevents field failures caused by ESD-induced latch-up or gate oxide rupture in 5 V-tolerant LIN PHYs. | Use Scenario: Safeguarding RS-485 driver/receiver inputs in factory automation PLC I/O modules exposed to cable-borne surges. IC Role / Device Role / Timing Role: Dual-line clamping device absorbing 1.9 A (10/1000 µs) transients on differential pair while maintaining <100 pF loading. Use Value: Eliminates need for separate TVS diodes per line, reducing BOM count and PCB footprint in space-limited DIN-rail mount designs. |
| Power Management Signal Monitoring | Infotainment System Button Interface |
Use Scenario: Protecting voltage sense and enable lines connected to PMICs or battery management ICs in start-stop systems. IC Role / Device Role / Timing Role: Low-leakage (0.1 nA) ESD suppressor preventing false wake-up or shutdown due to transient coupling on bias rails. Use Value: Ensures stable operation across -40 °C to +125 °C ambient range without compromising quiescent current budget. | Use Scenario: Shielding tactile switch inputs (e.g., volume, mode buttons) in head units from user ESD events during vehicle operation. IC Role / Device Role / Timing Role: Common-anode dual-diode routing surge current from either switch line directly to chassis ground. Use Value: Achieves >30 kV ESD immunity without adding series resistance that would degrade tactile response time. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional dual-line ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor SZMMBZ16VALT1G | Identical electrical specs and SOT23 package; same AEC-Q101 qualification; minor marking variation (%H7 vs. H7). | No functional difference; drop-in replacement with identical thermal and layout behavior. | Select when multi-source supply assurance is required without redesign. |
| Vishay SMA6J13A | Single-channel 13 V unidirectional TVS in SMA package; higher 600 W peak power but larger footprint and no dual-line integration. | Requires two devices for dual-line protection; unsuitable for space-constrained automotive modules. | Choose only if higher 8/20 µs surge rating (>11 A) is mandatory and board area permits discrete placement. |
Compared with SZMMBZ16VALT1G, MMBZ16VAL offers identical performance and qualification-making it a direct alternate; versus SMA6J13A, it trades peak power for integration density and lower parasitic capacitance, better fitting high-pin-count automotive ECUs.

FAQ
What is the maximum junction temperature for continuous operation?
The MMBZ16VAL supports continuous operation up to 150 °C junction temperature, verified per IEC 60134 absolute maximum ratings. This allows deployment in under-hood automotive locations where ambient temperatures reach 125 °C, provided PCB copper area and airflow maintain thermal resistance below 25 °C/W.
Can MMBZ16VAL protect bidirectional signal lines like USB or I²C?
No-MMBZ16VAL is unidirectional only and unsuitable for true bidirectional lines. Its common-anode configuration clamps positive transients on Pins 1/2 to Pin 3 but provides no negative-voltage protection. For bidirectional signals, use dedicated bidirectional arrays such as Nexperia PESD5V0S1BA.
How does the 76–95 pF capacitance affect signal integrity on a 125 kbps CAN bus?
At 125 kbps, the 76–95 pF capacitance introduces negligible rise-time degradation (<1 ns added delay) and no measurable bit error rate impact on standard CAN physical layer implementations. Layout best practices-short traces, ground plane proximity-ensure full compliance with ISO 11898-2.
Is the 30 kV ESD rating applicable to both contact and air discharge tests?
Yes-the ±30 kV rating applies to both IEC 61000-4-2 contact discharge and air discharge test methods. Testing used ten non-repetitive pulses per polarity, confirming robustness across real-world ESD event types encountered during vehicle assembly and service.
