Product details
Overview
NZL6V8AXV3T3G from onsemi is a dual common-anode unidirectional ESD protection diode in SC−89 package, rated for 6.8 V breakdown voltage (min 6.46 V, max 7.14 V), 1.0 µA max reverse leakage at 4.5 V VRWM, and 11.9 V clamping voltage at 1.0 A surge current. It delivers Class N ESD protection (>16 kV HBM) and meets IEC61000−4−2 Level 4 for USB, HDMI, and I/O line protection in space-constrained consumer and industrial interfaces.
For engineers reviewing the NZL6V8AXV3T3G datasheet, pinout, applications, or equivalent options, key selection criteria include working peak reverse voltage (4.5 V), low clamping voltage (11.9 V @ 1 A), dual-line common-anode topology, SC−89 footprint compatibility, and AEC−Q101 qualification for automotive-adjacent designs.
Technical Context
The NZL6V8AXV3T3G integrates two monolithic silicon Zener junctions sharing a single anode terminal (Pin 3), enabling independent protection of two signal lines with minimal PCB area. Its unidirectional configuration supports polarity-sensitive interfaces such as UART, SPI, and GPIO where ground-referenced transient suppression is required.
Designed for IEC61000−4−2 Level 4 compliance, it sustains 8 kV contact and 15 kV air discharge events while maintaining <1.0 µA leakage at 4.5 V and clamping transients to ≤11.9 V at 1.0 A (8/20 µs pulse). Thermal resistance is 525 °C/W, limiting steady-state power dissipation to 240 mW on FR−5 board at 25°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 4.5 V - Maximum continuous reverse operating voltage before significant leakage; sets upper limit for protected signal swing. |
| VBR (min/typ/max) | 6.46 / 6.8 / 7.14 V - Breakdown threshold at 5 mA test current; defines onset of clamping action. |
| VC @ IPP = 1.0 A | 11.9 V - Clamping voltage during 8/20 µs surge; determines maximum stress seen by downstream IC. |
| IR @ VRWM | ≤1.0 µA - Reverse leakage at rated working voltage; ensures negligible DC loading on high-impedance lines. |
| ESD Rating (HBM) | >16 kV - Human Body Model rating per JESD22−A114; exceeds Class N requirement for robust handling. |
| IEC61000−4−2 Level | Level 4 - Supports 8 kV contact / 15 kV air discharge immunity; validated for industrial and medical equipment. |
| Package | SC−89 (Case 463C, Style 4) - 3-lead surface-mount package with 1.6 mm × 0.8 mm footprint; MSL 1, 260°C reflow compatible. |
Pinout & Package
SC−89 package: void-free thermosetting epoxy case (UL 94 V−0), matte tin lead finish, 100% Pb−free and RoHS compliant. Mounting position unrestricted; qualified for 260°C peak reflow (MSL 1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode (Line 1) | Connects to first protected signal line (e.g., USB D+); conducts during positive transients relative to shared anode. |
| Pin 2 | Cathode (Line 2) | Connects to second protected signal line (e.g., USB D−); operates independently but shares Pin 3 anode reference. |
| Pin 3 | Common Anode | Single ground or supply rail connection point; enables dual-line protection without discrete anode routing. |
Key Features
| Feature | Design Value |
|---|---|
| Dual common-anode topology | Reduces component count and PCB area by 50% vs. two discrete diodes; eliminates separate anode traces. |
| Low clamping voltage (11.9 V @ 1 A) | Minimizes voltage overshoot on protected lines, preserving margin for 5 V-tolerant interface ICs. |
| 1.0 µA max reverse leakage @ 4.5 V | Prevents signal distortion or bias shift in high-impedance analog or digital I/O paths. |
| AEC−Q101 qualified | Validated for automotive-adjacent applications including infotainment I/O, telematics ports, and body control modules. |
| SC−89 footprint compatibility | Enables drop-in replacement for other SC−89 ESD diodes (e.g., NZL5V6AXV3T1G, NZL7V5AXV3T1G) without layout change. |
Applications
| USB 2.0 Interface Protection | HDMI DDC Line Protection |
|---|---|
|
Use Scenario: Protecting differential data pairs (D+/D−) in portable USB peripherals against ESD events during hot-plug insertion. IC Role / Device Role: Unidirectional transient voltage suppressor placed between connector and USB transceiver IC.

IC Role / Device Role: Dual-line ESD clamp referenced to system ground, installed adjacent to HDMI connector. Use Value: Provides bidirectional-like protection via dual cathodes sharing one anode, meeting IEC61000−4−2 Level 4 without increasing trace count. |
| Industrial Keypad Interface | Medical Sensor I/O Protection |
|
Use Scenario: Shielding membrane keypad scan lines in factory HMIs exposed to operator touch-induced ESD. IC Role / Device Role: Common-anode dual diode routing each row/column line to ground through dedicated cathode pins. Use Value: Enables compact 3-pin solution for 2-line protection, reducing BOM cost and routing complexity in tight 4-layer PCBs. |
Use Scenario: Guarding analog sensor inputs (e.g., temperature, pressure) in portable diagnostic equipment. IC Role / Device Role: Low-leakage (≤1.0 µA) ESD shunt placed at front-end connector to prevent latch-up in precision ADC drivers. Use Value: Maintains signal integrity with sub-nA leakage at 4.5 V bias, avoiding offset errors in µV-level biomedical measurements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NZL6V8AXV3T1G | Same electrical specs, but supplied in 3,000-piece tape-and-reel vs. 10,000-piece for NZL6V8AXV3T3G; identical SC−89 package and marking (L2). | Preferred for prototyping and low-volume production due to smaller reel size and faster fulfillment. | Select NZL6V8AXV3T1G when demand volume is under 5k units/year or when minimizing initial inventory investment is critical. |
| SZNZL6V8AXV3T3G | Adds SZ prefix indicating automotive-specific traceability, PPAP documentation, and extended temperature validation per AEC−Q101. | Required for Tier 1 automotive subsystems (e.g., center stack displays, ADAS sensor hubs) needing full PPAP submission. | Choose SZNZL6V8AXV3T3G only when OEM mandates automotive-grade documentation; otherwise NZL6V8AXV3T3G suffices for industrial/medical use. |
Compared with NZL6V8AXV3T1G and SZNZL6V8AXV3T3G, the NZL6V8AXV3T3G offers identical electrical performance and SC−89 packaging but targets high-volume industrial and medical applications requiring 10k/reel logistics and standard AEC−Q101 qualification-without automotive documentation overhead.

FAQ
What is the maximum working peak reverse voltage (VRWM) for NZL6V8AXV3T3G?
The NZL6V8AXV3T3G has a VRWM of 4.5 V, meaning it can continuously block up to 4.5 V in reverse bias without exceeding its specified leakage current of 1.0 µA. This value is confirmed in the Electrical Characteristics table on page 2 of the official datasheet and defines the highest steady-state voltage the device tolerates before entering breakdown during normal operation.
Does NZL6V8AXV3T3G support bidirectional ESD protection?
No, NZL6V8AXV3T3G is a unidirectional ESD protection diode with dual cathodes and a common anode. It protects two lines against positive transients only (relative to the shared anode). For true bidirectional protection, external circuitry or a dedicated bidirectional device like the ESD9B5.0ST5G would be required.
What is the clamping voltage (VC) of NZL6V8AXV3T3G at 1.0 A surge current?
The clamping voltage VC of NZL6V8AXV3T3G is 11.9 V when subjected to a 1.0 A (8/20 µs) surge current, as specified in the Electrical Characteristics table. This value represents the maximum voltage that appears across the protected line during transient suppression and is critical for ensuring downstream ICs remain within their absolute maximum ratings.
Is NZL6V8AXV3T3G qualified for automotive applications?
The NZL6V8AXV3T3G is AEC−Q101 qualified and PPAP capable, making it suitable for automotive-adjacent applications such as infotainment I/O and telematics ports. However, for full automotive subsystems requiring OEM-mandated PPAP documentation, the SZNZL6V8AXV3T3G variant-with explicit SZ-prefix traceability-is required instead.
What package type does NZL6V8AXV3T3G use, and what are its key mechanical features?
NZL6V8AXV3T3G uses the SC−89 package (Case 463C, Style 4), a 3-lead surface-mount outline measuring 1.6 mm × 0.8 mm. Key features include void-free thermosetting epoxy (UL 94 V−0), 100% matte tin lead finish, MSL 1 rating, and compatibility with 260°C peak reflow soldering-enabling reliable automated assembly in high-volume manufacturing.
