Product details
Overview
NZL5V6AXV3T1 from onsemi is a dual common-anode unidirectional ESD protection diode in SC−89 package, rated for 5.6 V breakdown voltage (min 5.32 V), 7.0 V clamping voltage at 1 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 bus lines.
For engineers reviewing the NZL5V6AXV3T1 datasheet, pinout, applications, or equivalent options, key selection criteria include working peak reverse voltage (3.0 V), low leakage (<5.0 µA), bidirectional configuration capability, IEC61000−4−2 Level 4 compliance, and SC−89 footprint compatibility with high-density PCB layouts.
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 paths without cross-coupling. Its unidirectional operation supports DC-biased lines requiring asymmetric clamping.
The SC−89 package delivers thermal resistance of 525°C/W and supports reflow up to 260°C (MSL 1), while its 100% matte tin lead finish ensures solderability and RoHS compliance. The device meets AEC−Q101 qualification for automotive-grade reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VBR) | 5.32–5.88 V @ IT = 5.0 mA - defines precise overvoltage triggering threshold for line protection |
| Clamping Voltage (VC) | 7.0 V @ IPP = 1.0 A - limits transient voltage seen by downstream ICs during ESD events |
| Working Peak Reverse Voltage (VRWM) | 3.0 V - maximum continuous DC bias before leakage rises significantly; sets usable voltage margin |
| ESD Rating (HBM) | >16 kV - exceeds Class N requirement, suitable for handheld and peripheral equipment handling |
| Leakage Current (IR) | <5.0 µA @ VRWM - ensures minimal signal loading and power loss in battery-powered systems |
| IEC61000−4−2 Level | Level 4 (±8 kV contact / ±15 kV air) - certified immunity for industrial and medical end-equipment |
| Package | SC−89 (Case 463C, Style 4) - 3-lead surface-mount package with 1.6 mm × 0.8 mm footprint for ultra-compact layout |
Pinout & Package
SC−89 package: void-free thermosetting plastic, UL 94 V−0 rated, 100% matte Sn lead finish, MSL 1 compliant, 260°C max reflow temperature.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode (Line 1) | Connects to first protected signal line; reverse-biased during normal operation, conducts during positive transients |
| Pin 2 | Cathode (Line 2) | Connects to second protected signal line; electrically isolated from Pin 1, shares common anode path |
| Pin 3 | Anode | Common return node tied to system ground or negative rail; enables dual-line protection in single footprint |
Key Features

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 | Same SC−89 package, 5.0 V VRWM, 13.5 V VC @ 1 A, higher clamping voltage | Less effective for 3.3 V systems due to tighter voltage margin between VRWM and VC | Prefer NZL5V6AXV3T1 when clamping below 7.5 V is required for 3.3 V logic protection |
| CM1213A-03SO | 3-pin SOT-23, 3.3 V VRWM, 12 V VC @ 1 A, higher capacitance (15 pF) | Higher signal distortion risk on high-speed lines due to larger junction capacitance | Choose NZL5V6AXV3T1 for lower 5.0 pF typical capacitance in bidirectional mode and tighter VC spec |
Compared with ESD5Z5.0T1G and CM1213A-03SO, NZL5V6AXV3T1 offers superior voltage margin (3.0 V VRWM → 7.0 V VC) and lower parasitic capacitance, making it optimal for noise-sensitive 3.3 V digital interfaces where signal fidelity and low leakage are critical.

FAQ
What is the maximum clamping voltage of NZL5V6AXV3T1 under 1 A ESD surge?
The NZL5V6AXV3T1 has a maximum clamping voltage (VC) of 7.0 V when subjected to a 1.0 A peak pulse current (IPP), as specified in the Electrical Characteristics table. This value is measured using the 8/20 µs waveform per IEC61000−4−2, ensuring predictable voltage limiting during real-world ESD events. The NZL5V6AXV3T1 maintains this performance across its operating temperature range of −55°C to +150°C.
Can NZL5V6AXV3T1 be used in bidirectional signal lines like USB D+ and D−?
Yes, NZL5V6AXV3T1 supports bidirectional configuration by connecting both cathodes (Pins 1 and 2) to the protected lines and the common anode (Pin 3) to ground-effectively forming two back-to-back diodes. Its SC−89 package and dual-junction design allow this mode without external components. The NZL5V6AXV3T1 achieves ~5.0 pF typical capacitance in bidirectional mode, making it suitable for USB 2.0 full-speed applications.
Is NZL5V6AXV3T1 qualified for automotive applications?
Yes, the SZNZL5V6AXV3T1G variant (ordering part number referenced in the datasheet) is AEC−Q101 qualified and PPAP capable, meeting automotive reliability standards. While NZL5V6AXV3T1 itself carries the standard industrial grade, the SZ-prefix version is explicitly validated for automotive use. For automotive designs, specify SZNZL5V6AXV3T1G to ensure full qualification coverage. The NZL5V6AXV3T1 shares identical electrical specs and package with its automotive counterpart.
What is the thermal resistance (RJA) of NZL5V6AXV3T1 on FR-5 board?
The NZL5V6AXV3T1 has a junction-to-ambient thermal resistance (RJA) of 525°C/W when mounted on an FR-5 board per the datasheet's Maximum Ratings table. This value assumes minimum recommended copper pad layout. At 25°C ambient, the device supports 240 mW total power dissipation, derating linearly above that temperature. This RJA confirms suitability for low-power, intermittent surge duty-not continuous power dissipation. The NZL5V6AXV3T1 must be applied within these thermal limits to maintain reliability.
Does NZL5V6AXV3T1 meet IEC61000−4−2 Level 4 for both contact and air discharge?
Yes, NZL5V6AXV3T1 meets IEC61000−4−2 Level 4: ±8 kV contact discharge and ±15 kV air discharge. This is explicitly stated in the Specification Features section and verified in Figures 6 and 7 of the datasheet. The device's 16 kV Human Body Model (HBM) rating further reinforces its robustness. When implementing NZL5V6AXV3T1 in a system, proper PCB layout-including short traces to ground and minimized loop area-is required to achieve full Level 4 performance. The NZL5V6AXV3T1 delivers certified protection without requiring additional external components.
