Product details
Overview
NZ8D16V4MX2WT5G from onsemi is a bidirectional Zener ESD protection diode designed for single-line transient voltage suppression in automotive and IVN systems. It features a 13.0 V working peak reverse voltage, 16.8 V typical breakdown voltage at 1 mA, 18.0 V clamping voltage at 1.0 A pulse, ±30 kV IEC 61000-4-2 contact ESD rating, and ultra-low 1.0 nA reverse leakage at 13 V.
For engineers reviewing the NZ8D16V4MX2WT5G datasheet, pinout, applications, or equivalent options, key selection criteria include bidirectional clamping performance, wettable flank X2DFNW2 package compatibility with AOI, and AEC-Q101 qualification for automotive ECU use.
Technical Context
This device implements a symmetric dual-Zener structure enabling bidirectional transient clamping between pins 1 and 2. Its design targets fast response to ESD events per IEC 61000-4-2 (8/20 µs) and ISO 10605 (330 pF/330 Ω), with guaranteed clamping below 18.0 V at 1.0 A and sustained energy handling up to 4.5 A peak pulse current.
The X2DFNW2 package integrates wettable flanks for reliable solder-joint inspection and supports high-density PCB layouts. Thermal resistance is 400°C/W (junction-to-ambient), and operation is specified from −55°C to +150°C - meeting under-hood automotive requirements without derating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Peak Reverse Voltage | 13.0 V - defines maximum continuous DC or AC RMS voltage the device blocks before conduction begins |
| Breakdown Voltage | 16.8 V typ @ 1 mA - precise voltage threshold where Zener conduction initiates in either polarity |
| Clamping Voltage | 18.0 V @ 1.0 A - maximum voltage seen by protected circuit during standardized 8/20 µs surge event |
| ESD Rating | ±30 kV contact per IEC 61000-4-2 - ensures robustness against direct human-body ESD discharge |
| Reverse Leakage | 1.0 nA @ 13 V - negligible standby current that avoids loading sensitive signal lines |
| Package | X2DFNW2 (1.0 × 0.6 × 0.37 mm) - ultra-compact, AOI-compatible footprint with wettable flanks |
Pinout & Package
The NZ8D16V4MX2WT5G is housed in an X2DFNW2 surface-mount package (Case 711BG), measuring 1.0 mm × 0.6 mm × 0.37 mm with 0.65 mm pitch and wettable flank terminations for automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |

| Pin 2 | Cathode/Anode (bidirectional) | Complementary terminal forming dual-Zener pair; connects to ground or reference rail |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal lines without polarity constraints |
| Wettable flank terminations | Supports automated optical inspection of solder joints - critical for automotive production traceability |
| AEC-Q101 qualification | Validated for automotive electronics including ECUs and in-vehicle networking (IVN) subsystems |

Applications
| Automotive Engine Control Unit (ECU) | In-Vehicle Networking (IVN) |
|---|---|
Use Scenario: Protecting CAN FD or LIN bus transceiver I/O pins from ESD events during vehicle assembly or service. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed directly at connector interface. Use Value: Maintains signal integrity with 18.0 V clamping at 1.0 A while surviving ±30 kV contact ESD per IEC 61000-4-2. | Use Scenario: Safeguarding low-voltage sensor inputs (e.g., temperature, pressure) in ADAS domain controllers. IC Role / Device Role / Timing Role: Standoff protection device shunting transients to ground before they reach precision analog front-ends. Use Value: 1.0 nA leakage prevents offset drift in microvolt-level sensor signals; AEC-Q101 ensures reliability over 15-year vehicle life. |
| Voltage-Sensitive Analog Circuits | Infotainment System USB Interfaces |
Use Scenario: Shielding ADC reference inputs or op-amp feedback networks from board-level ESD coupling. IC Role / Device Role / Timing Role: Low-capacitance (<15 pF, per datasheet) shunt protector preserving bandwidth and settling time. Use Value: 13.0 V VRWM allows use on 12 V rails; 16.8 V VBR ensures clean turn-on without false triggering during normal operation. | Use Scenario: Adding secondary ESD protection on USB 2.0 D+/D− lines downstream of integrated transceiver ESD cells. IC Role / Device Role / Timing Role: Discrete Zener clamp augmenting built-in protection to meet ISO 10605 150 pF / 2 kΩ requirements. Use Value: ±30 kV air and contact ratings exceed automotive infotainment test limits; X2DFNW2 footprint minimizes layout area. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SZ1.5SMC15AT3G | Unidirectional, higher 15 V VRWM, SMC package (4.5 × 3.2 mm) | Requires separate devices per polarity; unsuitable for bidirectional AC lines | Select only when unidirectional clamping and larger board space are acceptable |
| ESD9B5.0ST5G | Bidirectional, 5.0 V VRWM, same X2DFNW2 package, lower clamping (8.5 V @ 1 A) | Optimized for 3.3 V/5 V logic; insufficient for 12 V automotive supply rail protection | Prefer for low-voltage digital interfaces; not suitable as drop-in replacement for NZ8D16V4MX2WT5G |
Compared with SZ1.5SMC15AT3G and ESD9B5.0ST5G, the NZ8D16V4MX2WT5G uniquely combines bidirectional 13 V operation, automotive-grade AEC-Q101 qualification, and ultra-compact wettable-flank packaging - making it the only option qualified for direct placement on 12 V IVN signal lines requiring ±30 kV ESD immunity.

FAQ
What is the clamping voltage specification for NZ8D16V4MX2WT5G?
The NZ8D16V4MX2WT5G has a clamping voltage of 18.0 V at 1.0 A peak pulse current (8/20 µs waveform), as measured per IEC 61000-4-2. This value ensures protected circuits experience no more than 18.0 V during standardized ESD transients, preserving functionality of downstream 12 V–rated components. The NZ8D16V4MX2WT5G maintains this performance across its full operating temperature range.
Is NZ8D16V4MX2WT5G qualified for automotive applications?
Yes, NZ8D16V4MX2WT5G is AEC-Q101 qualified and PPAP capable. It is explicitly rated for automotive ECU and in-vehicle networking use, with guaranteed operation from −55°C to +150°C, ±30 kV ESD immunity, and wettable flank packaging supporting automotive manufacturing traceability requirements. The "SZ" prefix variant (SZNZ8D16V4MX2WT5G) meets additional site-control requirements.
What package type does NZ8D16V4MX2WT5G use?
NZ8D16V4MX2WT5G uses the X2DFNW2 package (Case 711BG), a 2-terminal, ultra-compact 1.0 mm × 0.6 mm × 0.37 mm leadless package with wettable flanks. This footprint enables high-density routing and automated optical inspection - essential for automotive PCB assembly. The device ships in 8,000-unit tape-and-reel format.
Does NZ8D16V4MX2WT5G support bidirectional protection?
Yes, NZ8D16V4MX2WT5G provides true bidirectional ESD protection via an internal symmetric dual-Zener structure. It clamps transients equally in both directions between pins 1 and 2, making it suitable for AC-coupled lines, differential buses (e.g., CAN, LIN), and floating signal paths where polarity is undefined. This eliminates the need for two discrete unidirectional devices.
What is the maximum reverse leakage current of NZ8D16V4MX2WT5G?
The maximum reverse leakage current of NZ8D16V4MX2WT5G is 10.0 nA at VRWM = 13 V and TA = 25°C, with a typical value of 1.0 nA. This ultra-low leakage prevents loading of high-impedance nodes such as sensor outputs, reference voltages, or precision analog inputs - a critical requirement in automotive and industrial measurement systems.
