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, this device is selected for dual-line unidirectional ESD protection where low leakage (0.1 nA typ.), high surge robustness (14 A @ 8/20 µs), and AEC-Q101 qualification are required in space-constrained automotive and industrial PCB layouts.
Technical Context
The MMBZ16VAL integrates two identical unidirectional TVS diodes sharing a common anode (Pin 3), enabling independent protection of two signal paths referenced to ground. Its VBR = 15.2–16.8 V (IR = 1 mA) ensures reliable turn-on before system-level damage, while low 76–95 pF capacitance preserves signal integrity on data lines up to ~100 MHz.
Clamping performance is characterized under standardized pulse waveforms: 23–28 V at 11 A (8/20 µs per IEC 61000-4-5) and 19.5–23 V at 1.7 A (10/1000 µs per IEC 61643-321). Junction temperature operation up to 150 °C supports under-hood automotive deployment without derating.
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) | 15.2–16.8 V @ 1 mA - Confirmed turn-on threshold ensuring early clamping during transients. |
| Clamping Voltage (VCL) | 19.5–23 V @ 1.7 A, 10/1000 µs - Peak voltage seen by downstream IC during surge; limits stress on connected transceivers. |
| Peak Pulse Current (IPPM) | 14 A @ 8/20 µs - Withstands high-energy surges typical of load dump or inductive switching events. |
| ESD Withstand (IEC 61000-4-2) | ±30 kV contact / ±30 kV air - Meets automotive-grade ESD immunity requirements without external filtering. |
| Diode Capacitance (Cd) | 76–95 pF @ 0 V, 1 MHz - Low enough to avoid signal distortion on USB 2.0, I²C, or LIN bus interfaces. |
| Reverse Leakage (IRM) | 0.1 nA typ. @ 13 V - Negligible DC loading on high-impedance sensor or communication lines. |
Pinout & Package
Encapsulated in a standard SOT23 (TO-236AB) surface-mount plastic package measuring 2.9 mm × 1.3 mm × 1.0 mm with 1.9 mm lead pitch, the MMBZ16VAL uses a three-terminal common-anode configuration optimized for compact dual-line protection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (Cathode 1) | Connects to first signal line requiring unidirectional ESD protection; conducts transient current to common anode (Pin 3). |
| 2 | K2 (Cathode 2) | Connects to second independent signal line; enables simultaneous protection of two traces without shared cathode routing. |
| 3 | A (Common Anode) | Connected to system ground; serves as return path for surge current from either cathode during positive transients. |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional dual-line protection | Two independent cathodes (Pins 1 & 2) share one grounded anode (Pin 3), eliminating need for discrete diodes or complex layout. |
| AEC-Q101 qualification | Validated for automotive applications including engine control units, body electronics, and infotainment systems per stress test requirements. |
| Low clamping voltage tolerance | VCL = 19.5–23 V at 1.7 A ensures consistent overvoltage limiting across production lots and temperature range (−55 °C to 150 °C). |
| High ESD immunity | ±30 kV contact discharge rating exceeds ISO 10605 requirements for 150 pF/330 Ω network, reducing need for secondary protection layers. |
| Thermal robustness | Rated junction temperature up to 150 °C allows placement near heat sources (e.g., power regulators) without thermal derating. |
Applications
| Automotive CAN Bus Protection | Industrial Sensor Interface Protection |
|---|---|
|
Use Scenario: Protecting CAN_H and CAN_L lines in automotive ECUs against ESD events during assembly, service, or vehicle operation. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed between each bus line and chassis ground, responding within nanoseconds to suppress transients above 13 V. Use Value: Prevents latch-up or permanent damage to CAN transceivers (e.g., TJA1042) while maintaining <1% signal rise-time degradation due to 76–95 pF capacitance. |
Use Scenario: Safeguarding analog outputs (4–20 mA) and digital I/O (RS-485) of PLC modules exposed to field wiring surges. IC Role / Device Role / Timing Role: Dual-cathode ESD suppressor mounted at connector entry point, shunting fast transients before reaching isolation barriers or ADC front-ends. Use Value: Enables single-component protection of both signal polarity directions without bidirectional diode trade-offs in leakage or capacitance. |
| Automotive LIN Bus Protection | Power Management Signal Line Protection |
|
Use Scenario: Shielding LIN transceiver pins (e.g., MC33662) in door modules and seat controllers from ESD during manufacturing handling. IC Role / Device Role / Timing Role: Common-anode configuration allows direct connection of LIN bus and wake-up line to respective cathodes, with shared ground return. Use Value: Reduces BOM count versus two discrete SOD-323 diodes while maintaining 0.1 nA leakage to avoid false wake-up triggers. |
Use Scenario: Protecting enable, fault, and feedback signals in DC-DC converter modules used in ADAS camera power supplies. IC Role / Device Role / Timing Role: Clamps voltage spikes induced by MOSFET switching noise or inductive coupling on low-voltage control lines. Use Value: 13 V VRWM aligns with 12 V nominal supply rails, allowing safe operation during cold-crank (6.5 V) and load-dump (up to 40 V) conditions. |
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 NSPU3051MR6T1G | Lower VRWM = 3.3 V; higher Cd = 120 pF; same SOT-23 package and common-anode topology. | Targeted at 3.3 V logic-level interfaces (e.g., USB, HDMI), not 12 V automotive buses. | Select when protecting low-voltage digital signals where tighter clamping (VCL = 9 V @ 1 A) outweighs capacitance penalty. |
| Vishay SMAJ13A | Single-line unidirectional TVS; higher IPPM = 25 A @ 8/20 µs but requires two devices for dual-line coverage; DO-214AC package. | Used in high-energy surge environments (e.g., power input stages), not signal-line ESD. | Choose only if peak current >14 A is mandatory and board area permits larger package and duplicated components. |
Compared with NSPU3051MR6T1G and SMAJ13A, the MMBZ16VAL uniquely balances 13 V standoff, dual-line integration, AEC-Q101 compliance, and 76–95 pF capacitance-making it optimal for cost- and space-sensitive 12 V automotive signal protection where single-device simplicity and reliability are critical.

FAQ
What is the maximum operating temperature for MMBZ16VAL?
The MMBZ16VAL is rated for junction temperatures up to 150 °C and ambient temperatures from −55 °C to 150 °C, validated per AEC-Q101 stress testing. This enables direct placement on engine control unit PCBs near power stages without thermal derating, provided PCB copper area and airflow meet datasheet thermal resistance guidelines (RthJA = 375 K/W).
Can MMBZ16VAL protect bidirectional signal lines like RS-485?
No-MMBZ16VAL is strictly unidirectional and configured for common-anode operation, making it unsuitable for bidirectional lines without external circuitry. For RS-485, a bidirectional TVS such as PESD5V0S1BA (common-cathode dual diode) or dedicated RS-485 ESD array is required to clamp both positive and negative transients symmetrically.
How does the common-anode configuration affect PCB layout?
The common-anode (Pin 3) must be connected directly to a low-impedance system ground plane; Pins 1 and 2 route independently to protected signal lines. This avoids shared cathode routing that could couple transients between lines and eliminates need for separate ground vias per diode-reducing layout complexity and parasitic inductance in high-speed protection paths.
Is MMBZ16VAL compatible with lead-free reflow soldering profiles?
Yes-MMBZ16VAL is qualified for standard lead-free reflow per JEDEC J-STD-020, with peak temperature up to 260 °C. The recommended footprint matches Nexperia's SOT23 reflow land pattern (Fig. 17), using 0.6 mm solder paste stencil apertures and 3× 0.5 mm solder lands to ensure mechanical reliability and void-free joints under automotive thermal cycling.
