Product details
Overview
MMBZ16VTAL from Nexperia is a unidirectional double ESD protection diode in common-anode SOT23 (TO-236AB) package, designed for transient overvoltage protection of two independent signal lines. It delivers 13 V reverse standoff voltage, 16 V nominal breakdown (±2% tolerance), and clamps to ≤23 V at 1.7 A (10/1000 µs), with <0.1 nA leakage at VRWM - enabling robust ESD hardening in automotive CAN/LIN bus interfaces.
For engineers reviewing the MMBZ16VTAL datasheet, MMBZ16VTAL pinout, MMBZ16VTAL application, or MMBZ16VTAL equivalent, this device is selected for dual-line unidirectional protection where low capacitance (76–95 pF), AEC-Q101 qualification, and high surge robustness (14 A @ 8/20 µs) are critical for in-vehicle network reliability and industrial I/O port hardening.
Technical Context
This device implements a common-anode dual-cathode TVS structure optimized for bidirectional line protection using a single unidirectional configuration per cathode. Its tight ±2% VBR tolerance ensures predictable clamping onset across temperature, while its 76–95 pF capacitance at 0 V supports high-speed data lines up to ~100 Mbps without signal integrity degradation.
The 1.9 mm pitch SOT23 footprint enables compact placement near connectors or IC I/O pins. Thermal derating follows a typical 0.4 W/°C slope above 25 °C junction temperature, with maximum Tj = 150 °C and rated peak pulse power of 45 W (10/1000 µs) and 300 W (8/20 µs).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage (VRWM) | 13 V - Maximum continuous operating voltage before conduction; defines safe signal swing range for protected lines. |
| Breakdown Voltage (VBR) | 15.68–16.32 V @ 1 mA - Tight ±2% tolerance ensures consistent turn-on across production lots and temperature. |
| Clamping Voltage (VCL) | 19.5–23 V @ 1.7 A (10/1000 µs) - Limits transient energy delivered to downstream ICs during surge events. |
| Peak Pulse Current (IPPM) | 14 A @ 8/20 µs - Supports IEC 61000-4-5 Level 4 surge immunity testing on protected lines. |
| Diode Capacitance (Cd) | 76–95 pF @ 1 MHz, 0 V - Enables use on USB 2.0, LIN, and low-speed CAN without excessive signal attenuation. |
| ESD Withstand (IEC 61000-4-2) | ±30 kV contact / ±30 kV air - Meets automotive-grade ESD immunity requirements for exposed ports. |
| Leakage Current (IRM) | 0.1 nA typical @ 13 V - Minimizes DC loading on high-impedance sensor or reference lines. |
Pinout & Package
Encapsulated in a standard SOT23 (TO-236AB) plastic surface-mount package measuring 2.9 × 1.3 × 1.0 mm, with 1.9 mm lead pitch and gull-wing terminations compatible with reflow and wave soldering per IPC-7095 guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K1) | Cathode 1 | Connects to first protected signal line; conducts transient current to common anode during positive overvoltage events. |
| 2 (K2) | Cathode 2 | Connects to second protected signal line; operates independently from K1 under unidirectional surge conditions. |
| 3 (A) | Common Anode | Connected to system ground or local reference plane; serves as shared return path for both cathodes' surge currents. |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional dual-line protection | Single SOT23 device protects two independent signal paths with separate cathodes and shared anode - reduces board area vs. discrete diodes. |
| Tight VBR tolerance (±2%) | Ensures uniform clamping behavior across batches and temperatures, critical for predictable system-level ESD margin allocation. |
| AEC-Q101 qualification | Validated for automotive applications including engine control modules, body electronics, and infotainment I/O protection. |
| Low leakage (0.1 nA typ.) | Preserves accuracy in high-impedance analog sensing circuits and avoids false triggering in low-power wake-up lines. |
| High surge robustness (14 A @ 8/20 µs) | Withstands multiple IEC 61000-4-5 surges without parameter shift, supporting long-term field reliability in industrial environments. |
Applications
| Automotive CAN Bus Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting CAN_H and CAN_L lines in automotive ECUs against ESD from connector handling and load dump transients. IC Role / Device Role / Timing Role: Unidirectional TVS diode providing fast clamping (<1 ns response) to limit voltage excursions below transceiver absolute max ratings. Use Value: Maintains CAN signal integrity during ±30 kV ESD events while adding only 95 pF per line - no bitrate degradation at 500 kbps. |
Use Scenario: Shielding 4–20 mA current loop inputs and analog sensor outputs (e.g., pressure, temperature) in PLC I/O modules. IC Role / Device Role / Timing Role: Dual-cathode ESD clamp placed at PCB edge to shunt transients before reaching precision op-amps or ADC front-ends. Use Value: 0.1 nA leakage prevents offset errors in µA-level current loops; 13 V VRWM aligns with 24 V industrial supply rails. |

Use Scenario: Safeguarding D+ and D− lines of USB 2.0 host/device ports in infotainment head units and telematics gateways. IC Role / Device Role / Timing Role: Low-capacitance ESD suppressor placed adjacent to USB connector to minimize stub length and preserve signal rise time. Use Value: 76–95 pF capacitance meets USB 2.0 eye diagram mask requirements; clamps to ≤23 V at 1.7 A to protect PHY transceivers. |
Use Scenario: Hardening LIN bus master/slave nodes (e.g., door modules, seat controllers) against ESD during vehicle assembly and service. IC Role / Device Role / Timing Role: Common-anode dual-diode configured to clamp both LIN bus and wake-up line against ±30 kV contact discharge. Use Value: Single-device solution reduces BOM count; AEC-Q101 qualification ensures compliance with ISO 11898-4 and OEM ESD test plans. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-line unidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor SZMMBZ16VALT1G | Same 16 V VBR, but ±5% tolerance (vs. ±2%); 100 pF max capacitance (vs. 95 pF); not AEC-Q101 qualified. | Lacks automotive qualification; higher capacitance may affect >48 Mbps data lines. | Select when cost sensitivity outweighs AEC-Q101 requirement and signal bandwidth is ≤20 Mbps. |
| Vishay SMAJ13A | Single-line 13 V TVS in SMA package; 100 W (10/1000 µs) rating; 100 pF; no dual-cathode topology. | Requires two devices for dual-line protection; larger footprint (4.5 × 2.7 mm vs. 2.9 × 1.3 mm). | Choose only if existing design uses SMA footprints or requires higher 100 W pulse power than MMBZ16VTAL's 45 W. |
Compared with SZMMBZ16VALT1G and SMAJ13A, MMBZ16VTAL offers tighter VBR control, lower capacitance, and automotive qualification in a space-saving SOT23 - making it optimal for new automotive and high-density industrial designs requiring dual-line ESD hardening.

FAQ
What is the maximum clamping voltage under IEC 61000-4-2 ESD stress?
Under ±8 kV IEC 61000-4-2 contact discharge, MMBZ16VTAL clamps to +17 V (positive pulse) and −2 V (negative pulse) at 30 ns, as measured per the standard test setup with 150 pF/330 Ω network. This performance is verified in Figures 13 and 14 of the official Nexperia datasheet.
Can MMBZ16VTAL protect bidirectional signal lines like RS-485?
No - MMBZ16VTAL is unidirectional and configured for common-anode dual-cathode operation, suitable only for lines referenced to ground with positive-only transients. For true bidirectional protection (e.g., RS-485), a dedicated bidirectional TVS such as PESD5V0S1BA must be used instead.
Is thermal derating required for continuous operation at 125 °C ambient?
Yes - at Tamb = 125 °C, the maximum allowable power dissipation drops to approximately 50% of the 25 °C rating due to junction-to-ambient thermal resistance. Derating curves in Figure 5 show PPPM falls to ~20 W at 125 °C, requiring layout attention to copper area and airflow.
How does the common-anode configuration affect PCB routing?
The common-anode (pin 3) must be routed to a low-inductance ground plane or local ground pour, while cathodes (pins 1 and 2) connect directly to protected signal traces with minimal stub length. Separating K1/K2 traces prevents crosstalk, and grounding pin 3 before routing cathodes minimizes loop inductance during surge events.
