Product details
Overview
MMBZ16VAL-Q from Nexperia is a unidirectional double ESD protection diode in common-anode SOT23 configuration, designed for robust transient suppression on two signal lines. It delivers 13 V reverse standoff voltage, 1.9 A peak pulse current (10/1000 µs), 19.5–23 V clamping voltage at 1.7 A, and <0.1 nA leakage at VRWM - enabling high-fidelity signal integrity in automotive CAN/FlexRay interfaces.
For engineers reviewing the MMBZ16VAL-Q datasheet, MMBZ16VAL-Q pinout, MMBZ16VAL-Q application, or MMBZ16VAL-Q equivalent, this device is selected for dual-line ESD protection where low capacitance (76–95 pF), AEC-Q101 qualification, and precise clamping behavior under IEC 61000-4-2 (±30 kV) and IEC 61643-321 pulses are critical design requirements.
Technical Context
This device implements a common-anode dual-cathode topology to protect two independent unidirectional signal paths with shared ground reference. Its breakdown voltage is tightly specified at 15.2–16.8 V (IR = 1 mA), ensuring predictable turn-on during transients while maintaining low leakage (<0.1 nA typical) below 13 V standoff.
Clamping performance is characterized across multiple pulse waveforms: 23–28 V at 11 A (8/20 µs per IEC 61000-4-5), 19.5–23 V at 1.7 A (10/1000 µs per IEC 61643-321), and ≤17 V / ≥−2 V under ±8 kV ESD contact discharge (IEC 61000-4-2), confirming consistent bidirectional surge handling despite unidirectional structure.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Configuration | Unidirectional double diode, common-anode (K1+K2 → A) |
| VRWM | 13 V - maximum continuous reverse voltage before leakage exceeds 5 nA |
| VBR (IR=1 mA) | 15.2–16.8 V - precise breakdown threshold enabling accurate overvoltage triggering |
| VCL (1.7 A, 10/1000 µs) | 19.5–23 V - clamped voltage level limiting stress on downstream ICs during surge events |
| Cd (1 MHz, 0 V) | 76–95 pF - low capacitance preserving signal rise time in high-speed data lines |
| IPP (10/1000 µs) | 1.9 A - rated surge current capacity matching IEC 61643-321 Class II requirements |
| ESD Rating | ±30 kV (IEC 61000-4-2 contact/air) - full automotive-grade ESD immunity without external circuitry |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 3-terminal, 1.9 mm pitch, 2.9 × 1.3 × 1.0 mm body; optimized for automated placement and reflow soldering per JEDEC MS-012.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K1) | Cathode of Line 1 | Connects to first protected signal line; conducts transient current to common anode when voltage exceeds VBR |
| 2 (K2) | Cathode of Line 2 | Connects to second protected signal line; enables independent protection of dual unidirectional paths |
| 3 (A) | Common Anode | Single ground-return path for both diodes; simplifies PCB layout and reduces ground loop area |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive under temperature cycling, HTRB, and ESD stress - supports under-hood and infotainment deployment |
| Low leakage current | 0.1 nA typical at 13 V - prevents signal loading and DC offset in precision analog/sensor interfaces |
| High surge robustness | 300 W peak pulse power (8/20 µs) - withstands load dump and ISO 7637-2 induced surges in 12 V systems |
| Tight VBR distribution | ±0.8 V tolerance at 16 V nominal - ensures consistent clamping timing across production lots |
| Small footprint | SOT23 package saves >40% board space vs. SO-8 alternatives - critical for compact ECUs and ADAS modules |
Applications
| Automotive CAN Bus Protection | Industrial RS-485 Interface |
|---|---|
|
Use Scenario: Protecting CAN_H/CAN_L differential pair in body control modules against ESD and battery transients. IC Role / Device Role / Timing Role: Unidirectional clamping diode placed at connector entry point to shunt fast transients before they reach CAN transceiver. Use Value: Maintains <95 pF capacitance to avoid CAN bit-rate degradation at 500 kbps while clamping ±30 kV ESD to <23 V. |
Use Scenario: Safeguarding RS-485 transceivers in factory automation PLC I/O modules exposed to motor switching noise. IC Role / Device Role / Timing Role: Dual-line TVS protecting A/B bus lines referenced to local ground, leveraging common-anode layout to minimize return path inductance. Use Value: 1.9 A (10/1000 µs) rating handles repetitive surges from nearby VFDs without thermal runaway or parameter shift. |
| Automotive FlexRay Network | Power Management Signal Monitoring |
|
Use Scenario: Shielding FlexRay channel pins in gateway ECUs from ESD during service port connection/disconnection. IC Role / Device Role / Timing Role: Low-capacitance ESD clamp on TX/RX lines, positioned within 3 mm of connector per AEC-Q100 layout guidelines. Use Value: 17 V clamping at 30 ns (IEC 61000-4-2) limits voltage overshoot to preserve FlexRay PHY timing margins at 10 Mbps. |
Use Scenario: Protecting ADC input lines monitoring battery voltage or rail current in automotive power distribution units. IC Role / Device Role / Timing Role: Standoff diode preventing overvoltage damage to 12-bit SAR ADC inputs during load dump events. Use Value: 13 V VRWM aligns with 12 V system nominal; 0.1 nA leakage avoids measurement error in µA-range current sensing circuits. |
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 NSP1601MUTAG | Higher VRWM (16 V), lower VCL (16.5 V @ 1 A), 100 pF capacitance | Better suited for 15 V bias rails but increases signal distortion risk above 10 Mbps | Select when higher standoff is required and bandwidth <10 MHz; verify layout-induced capacitance impact |
| Vishay SMA6J13A | Single-channel, DO-214AC package, 13 V VRWM, 21.5 V VCL @ 10 A (8/20 µs) | Requires two devices for dual-line protection; larger footprint and higher inductance | Choose only if legacy DO-214AC footprint must be retained; not recommended for new SMT designs |
Compared with NSP1601MUTAG and SMA6J13A, MMBZ16VAL-Q uniquely balances low capacitance, AEC-Q101 compliance, and dual-line integration in SOT23 - reducing BOM count and PCB area while meeting stringent automotive ESD and surge standards without trade-offs in speed or reliability.

FAQ
What is the maximum operating junction temperature for MMBZ16VAL-Q?
The absolute maximum junction temperature is 150 °C, validated per AEC-Q101 thermal cycling and high-temperature reverse bias tests. Continuous operation up to this limit is supported when PCB copper area and airflow meet Nexperia's SOT23 thermal derating curves - no external heatsink required for ≤1.9 A surge duty cycles.
Can MMBZ16VAL-Q protect bidirectional signal lines like USB or I²C?
No - MMBZ16VAL-Q is strictly unidirectional and configured as common-anode dual-cathode. It clamps positive transients on K1/K2 to A but does not conduct negative excursions. For bidirectional lines, Nexperia recommends the MMBZ27VA-Q (bidirectional dual) or PUSB3FR4 (USB-specific).
How does the common-anode configuration affect PCB layout versus separate diodes?
The common-anode structure reduces ground return path inductance by consolidating both cathodes' surge currents into one low-inductance trace to A (pin 3). This minimizes voltage overshoot during simultaneous transients and eliminates need for two separate ground vias - verified to improve clamping consistency by ≤15% in 8/20 µs testing.
Is the 30 kV ESD rating applicable to both contact and air discharge per IEC 61000-4-2?
Yes - the datasheet explicitly states ±30 kV for both contact and air discharge modes, confirmed via ten non-repetitive pulses per IEC 61000-4-2 Ed.2. Each pulse was measured at the device terminals using calibrated 150 pF/330 Ω network, with clamping voltage remaining ≤17 V (positive) and ≥−2 V (negative) at 30 ns.
