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 signal lines. It delivers 13 V reverse standoff voltage, 16 V breakdown voltage (±2% tolerance), and clamps to ≤23 V at 1.7 A (10/1000 µs), with <0.1 nA leakage at VRWM - used in automotive CAN/LIN bus line protection.
For engineers reviewing the MMBZ16VTAL datasheet, MMBZ16VTAL pinout, MMBZ16VTAL application, or MMBZ16VTAL equivalent, key selection criteria include bidirectional vs. unidirectional configuration support, clamping voltage under 10/1000 µs surge, ESD robustness (30 kV contact/air), junction temperature rating (150 °C), and AEC-Q101 qualification for automotive deployment.
Technical Context
This device implements a dual-cathode, single-common-anode TVS topology optimized for low-capacitance (76–95 pF) ESD suppression on high-speed signal lines. Its tight ±2% VBR tolerance ensures predictable turn-on across production lots, while the 1.9 mm pitch SOT23 footprint enables compact routing near connectors or IC I/O pins.
The clamping behavior is characterized for both 8/20 µs (IEC 61000-4-5) and 10/1000 µs (IEC 61643-321) transients, with measured VCL = 23 V at IPP = 11 A (8/20 µs) and VCL = 23 V at IPP = 1.7 A (10/1000 µs). ESD immunity is validated per IEC 61000-4-2 to ±30 kV (contact/air).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 13 V - Maximum continuous reverse voltage before leakage exceeds 5 µA; defines safe operating margin for 12 V automotive systems. |
| VBR @ 1 mA | 15.68–16.32 V - Tight ±2% tolerance ensures consistent ESD trigger point across temperature and lot variation. |
| VCL @ 1.7 A (10/1000 µs) | 19.5–23 V - Clamping voltage limits downstream IC stress during slow surges like load dump coupling. |
| IPP (10/1000 µs) | 1.9 A - Peak pulse current rating aligned with IEC 61643-321; supports industrial transient immunity testing. |
| Cd @ 0 V, 1 MHz | 76–95 pF - Low capacitance preserves signal integrity on data lines up to ~100 Mbps (e.g., LIN, UART). |
| ESD Rating | ±30 kV (IEC 61000-4-2) - Validated for ten non-repetitive contact/air discharges; meets automotive ESD requirements. |
| AEC-Q101 Qualified | Yes - Certified for automotive-grade reliability including temperature cycling, HTRB, and mechanical shock per AEC standard. |
Pinout & Package
Encapsulated in TO-236AB (SOT23), a 3-terminal surface-mount plastic package measuring 2.9 × 1.3 × 1.0 mm with 1.9 mm lead pitch. The small outline supports high-density PCB layouts and automated reflow assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (Cathode 1) | Connects to first protected signal line; conducts transient current to common anode during positive ESD events. |
| 2 | K2 (Cathode 2) | Connects to second protected signal line; independent cathode enables dual-line unidirectional protection. |
| 3 | A (Common Anode) | Connected to system ground or reference plane; serves as shared return path for both cathodes during clamping. |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional dual-line protection | Single device protects two independent signal paths (e.g., LIN bus + sensor supply enable) without cross-talk. |
| Tight VBR tolerance (±2%) | Reduces design margin uncertainty and eliminates need for binning or post-production calibration. |
| Low IRM (0.1 nA typ.) | Minimizes standby power loss and avoids signal offset in high-impedance analog sensing circuits. |
| AEC-Q101 qualification | Validates suitability for under-hood automotive applications including temperature cycling (-55 °C to +150 °C). |
| 30 kV ESD immunity | Exceeds ISO 10605 requirements for vehicle-level ESD testing, reducing need for secondary protection layers. |
Applications
| Automotive LIN Bus Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting LIN transceiver I/O pins against ESD events during vehicle assembly or service. IC Role / Device Role: Unidirectional TVS clamp placed between LIN bus line and ground, with common anode tied to chassis ground. Use Value: Limits clamped voltage to ≤23 V during 1.7 A transients, ensuring LIN PHY remains within ABSOLUTE MAX ratings per ISO 17987-4. |
Use Scenario: Safeguarding 4–20 mA current loop inputs in PLC analog input modules exposed to field wiring surges. IC Role / Device Role: Dual-cathode ESD suppressor applied across signal and return lines, sharing ground reference. Use Value: Withstands 1.9 A (10/1000 µs) surges per line while adding only 95 pF capacitance - no impact on loop bandwidth. |
| Automotive Power Management Enable Lines | Consumer USB Data Line Protection |
Use Scenario: Shielding microcontroller GPIOs driving high-side power switches in battery management systems. IC Role / Device Role: Common-anode dual diode clamps each enable signal to ground, preventing latch-up from board-level ESD. Use Value: 0.1 nA leakage avoids false triggering of enable logic; ±30 kV ESD rating covers handling during module integration. |
Use Scenario: Adding secondary ESD protection on USB 2.0 D+/D− lines behind integrated port protection ICs. IC Role / Device Role: Two independent cathodes protect D+ and D− individually, with common anode grounded to minimize ground bounce. Use Value: 76–95 pF capacitance maintains USB 2.0 eye diagram integrity; 13 V VRWM avoids interference with 3.3 V signaling. |
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 | Same VBR (16 V), but wider VBR tolerance (±5%), higher Cd (120 pF), and no AEC-Q101 qualification. | Limited to industrial/commercial use; unsuitable for automotive due to missing qualification and higher capacitance. | Select when cost sensitivity outweighs automotive compliance and signal integrity requirements. |
| Vishay SMAJ13A | Single-line unidirectional TVS, 13 V VRWM, 200 W PPPM (8/20 µs), but requires two devices for dual-line protection. | Higher board area, increased BOM count, and no common-anode advantage for shared ground routing. | Choose only if legacy design uses SMA package or requires higher 8/20 µs surge rating (>11 A). |
Compared with SZMMBZ16VALT1G, MMBZ16VTAL offers tighter VBR control and automotive qualification; versus SMAJ13A, it reduces component count and layout area by integrating dual protection into one SOT23 device.

FAQ
What is the maximum junction temperature rating for MMBZ16VTAL?
The absolute maximum junction temperature (Tj) is 150 °C, verified per IEC 60134 limiting values. This rating supports operation in under-hood automotive environments and industrial enclosures with limited airflow, provided thermal resistance from junction-to-ambient is maintained below calculated limits using PCB copper pour and layout guidelines in the datasheet.
Can MMBZ16VTAL protect bidirectional signal lines?
No - MMBZ16VTAL is strictly unidirectional (common-anode configuration) and protects only positive-going transients on two separate lines. For bidirectional protection of a single line, a dedicated bidirectional TVS such as PESD5V0S1BA must be used instead.
How does the 10/1000 µs clamping voltage compare to the 8/20 µs rating?
VCL is 19.5–23 V at 1.7 A (10/1000 µs), versus 23–28 V at 11 A (8/20 µs). The slower 10/1000 µs waveform produces lower peak clamping voltage due to thermal time constant effects, making it more relevant for sustained surges like inductive kickback in relay drivers.
Is the SOT23 footprint compatible with standard reflow soldering profiles?
Yes - Nexperia provides validated reflow soldering footprints (Fig. 17) and recommends JEDEC J-STD-020-compliant profiles. The TO-236AB package withstands peak temperatures up to 260 °C for 10 seconds, supporting lead-free assembly without delamination or voiding when solder paste volume and stencil aperture match recommended dimensions.
