Product details
Overview
NZL5V6AXV3T1G from onsemi is a dual common-anode ESD protection diode in SC-89 package, rated for 5.6 V breakdown voltage (VBR), 7.0 V clamping voltage (VC) at 1.0 A surge, and 16 kV HBM ESD rating. It protects two I/O lines simultaneously in space-constrained interfaces such as USB, keyboard, or microprocessor data buses.
For engineers reviewing the NZL5V6AXV3T1G datasheet, pinout, applications, or equivalent options, key selection criteria include unidirectional dual-line clamping capability, low leakage (<5.0 µA), SC-89 footprint compatibility, and IEC61000-4-2 Level 4 compliance for industrial and computing systems.
Technical Context
This device implements a monolithic dual-junction silicon structure with shared anode (Pin 3) and separate cathodes (Pins 1 and 2), enabling independent protection of two signal lines without cross-coupling. Its unidirectional configuration supports forward-biased transient suppression on each line while maintaining low capacitance (typ. 4.8 pF at 0 V).
The NZL5V6AXV3T1G operates within −55 °C to +150 °C junction temperature range, features 525 °C/W thermal resistance, and delivers 10.1 W peak pulse power (8/20 µs waveform) with 7.0 V clamping at 1.0 A. It meets AEC-Q101 stress test requirements when marked with "SZ" prefix, though NZL5V6AXV3T1G itself is non-automotive grade.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VBR) | 5.32–5.88 V @ IT = 1 mA - defines precise turn-on threshold for transient suppression |
| Clamping Voltage (VC) | 7.0 V @ IPP = 1.0 A - limits maximum voltage seen by protected IC during ESD event |
| Working Peak Reverse Voltage (VRWM) | 5.0 V - maximum continuous DC voltage before significant leakage begins |
| Reverse Leakage (IR) | <5.0 µA @ VRWM - ensures minimal signal loading and power loss in standby |
| ESD Rating (HBM) | >16 kV - exceeds Class N requirement for robust handling in manufacturing and field use |
| IEC61000-4-2 Level | Level 4 (±8 kV contact / ±15 kV air) - certified for high-immunity industrial/commercial equipment |
| Package | SC-89 (Case 463C, 1.60 × 0.85 × 0.70 mm) - enables ultra-compact dual-line protection on dense PCBs |
Pinout & Package
SC-89 package: 3-lead, surface-mount, void-free thermosetting plastic case (UL 94 V-0), matte tin lead finish, MSL 1 rated for 260 °C reflow.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode (Line 1) | Connects to first protected signal line; reverse-biased during normal operation, conducts during overvoltage |
| Pin 2 | Cathode (Line 2) | Connects to second protected signal line; electrically isolated from Pin 1, shares common anode |
| Pin 3 | Anode | Common return path to ground or supply rail; establishes dual-unidirectional topology |
Key Features
| Feature | Design Value |
|---|---|
| Dual common-anode architecture | Enables independent protection of two signals in one SC-89 footprint, reducing component count and board area by 50% vs. discrete diodes |
| Low clamping voltage (7.0 V @ 1 A) | Ensures downstream logic ICs (e.g., 5 V tolerant microcontrollers) remain within safe operating voltage during ESD transients |
| Typical capacitance: 4.8 pF @ 0 V | Minimizes signal distortion and timing skew on high-speed lines like USB 2.0 or SPI clock/data pairs |
| Pb-free, halogen-free, RoHS-compliant | Meets global environmental regulations and eliminates hazardous material handling concerns in production and end-of-life recycling |
Applications
| USB 2.0 Data Line Protection | Keyboard/Mouse Interface Protection |
|---|---|
Use Scenario: Protecting D+ and D− lines of embedded USB peripherals against ESD events during hot-plug or handling. IC Role / Device Role / Timing Role: Unidirectional transient voltage suppressor placed between connector and USB transceiver IC.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD5Z5.0T1G | Single-channel SOD-523; 5.0 V VRWM; 13.5 V VC @ 1 A; higher clamping voltage | Requires two devices for dual-line protection; larger total footprint than NZL5V6AXV3T1G | Select when single-line protection suffices or when higher surge current rating (20 A) is prioritized over board space |
| CM1213A-03SR | Three-channel SC-70; 3.3 V VRWM; 10.5 V VC @ 1 A; integrated ESD + EMI filtering | Designed for low-voltage (3.3 V) I/O; includes 15 pF filtering capacitance not present in NZL5V6AXV3T1G | Choose for mixed-signal interfaces needing simultaneous ESD suppression and noise attenuation, but verify voltage compatibility |
Compared with ESD5Z5.0T1G and CM1213A-03SR, the NZL5V6AXV3T1G uniquely balances dual-line integration, 5.6 V Zener precision, and sub-7 V clamping in the smallest possible footprint-making it optimal for space-limited 5 V systems where predictable turn-on and minimal parasitic capacitance are critical.

FAQ
What is the exact pin configuration of NZL5V6AXV3T1G?
The NZL5V6AXV3T1G uses SC-89 package with Pin 1 = Cathode (Line 1), Pin 2 = Cathode (Line 2), and Pin 3 = Common Anode. This dual-cathode/common-anode layout enables independent unidirectional clamping on two signal paths sharing one ground or supply reference. The marking diagram on page 2 of the onsemi datasheet confirms Style 4 pinout.
Does NZL5V6AXV3T1G support bidirectional ESD protection?
The NZL5V6AXV3T1G is fundamentally unidirectional due to its common-anode structure, but it can be used in bidirectional configurations by connecting both cathodes to the protected lines and the anode to ground. In that arrangement, each cathode-anode junction clamps positive transients, while negative transients are blocked-so true bidirectional suppression requires external circuitry or complementary devices.
What is the maximum surge current rating for NZL5V6AXV3T1G?
The NZL5V6AXV3T1G is rated for 1.0 A peak pulse current (IPP) under the standard 8/20 µs waveform, delivering 10.1 W peak pulse power. At this current, clamping voltage remains at 7.0 V. Higher surge currents (e.g., 4.8 A) are supported only at reduced clamping performance (VC = 10.1 V), as specified in the datasheet's electrical characteristics table.
Is NZL5V6AXV3T1G compliant with automotive standards?
No, NZL5V6AXV3T1G is not AEC-Q101 qualified. The "SZ" prefix variants (e.g., SZNZL5V6AXV3T1G) are automotive-grade and PPAP-capable, but the base NZL5V6AXV3T1G is intended for commercial and industrial applications. Its qualification covers IEC61000-4-2 Level 4 and HBM >16 kV, but not full automotive stress testing.
How does NZL5V6AXV3T1G compare to NZL6V8AXV3T1G in terms of voltage ratings?
The NZL5V6AXV3T1G has a lower breakdown voltage (5.32–5.88 V) and working voltage (5.0 V) than NZL6V8AXV3T1G (6.46–7.14 V VBR, 4.5 V VRWM), making it suitable for 5 V logic systems. NZL6V8AXV3T1G targets 6–7 V rails or higher-threshold interfaces. Both share identical SC-89 packaging, pinout, and clamping behavior-but selecting the correct variant depends strictly on the protected line's operating voltage margin.
