Product details
Overview
NZL6V8AXV3T1 from onsemi is a dual common-anode unidirectional ESD protection diode in SC−89 package, featuring 6.8 V breakdown voltage (VBR), 4.5 V working peak reverse voltage (VRWM), and 11.9 V clamping voltage (VC) at 1 A surge current. It delivers 73 W peak pulse power and meets IEC61000−4−2 Level 4 for robust system-level ESD immunity in space-constrained I/O line protection.
For engineers reviewing the NZL6V8AXV3T1 datasheet, pinout, applications, or equivalent options, key selection criteria include VRWM margin vs. signal rail voltage, bidirectional configuration capability, low leakage (<1.0 µA), SC−89 footprint compatibility, and AEC−Q101 qualification status for automotive-grade designs.
Technical Context
This device implements a monolithic dual-junction silicon structure with shared anode (Pin 3) and separate cathodes (Pins 1 & 2), enabling independent protection of two signal lines in one compact package. Its unidirectional Zener clamping behavior operates only when cathode-to-anode voltage exceeds VBR, with fast response to ESD transients per IEC61000−4−2.
The SC−89 package supports both discrete unidirectional configurations (e.g., Pin 1–3 and Pin 2–3) and a single bidirectional mode using external circuitry. Thermal resistance (RJA = 525 °C/W) and 240 mW power dissipation rating are specified on FR−5 board with minimum recommended pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 4.5 V - Maximum continuous reverse voltage before significant leakage; sets upper limit for protected signal rail (e.g., 3.3 V or 5 V I/O). |
| VBR @ IT=5 mA | 6.46–7.14 V - Breakdown onset range; ensures reliable clamping above normal operating voltage but below IC damage thresholds. |
| VC @ IPP=1 A | 11.9 V - Clamping voltage during 8/20 µs surge; defines maximum transient voltage seen by downstream IC pins. |
| IR @ VRWM | <1.0 µA - Ultra-low reverse leakage preserves signal integrity and battery life in always-on interfaces. |
| Ppk | 73 W - Peak pulse power handling per IEC61000−4−2 contact discharge; determines survivability under 8 kV ESD events. |
| ESD Rating | Class N (>16 kV HBM) - Exceeds JEDEC JS-001 human-body model requirements for high-reliability end equipment. |
| Package | SC−89 (Case 463C) - 3-pin surface-mount package with 1.6 mm × 0.8 mm footprint; MSL 1 rated for lead-free reflow up to 260 °C. |
Pinout & Package
SC−89 package: void-free thermosetting epoxy case (UL 94 V−0), 100% matte tin lead finish, 260 °C max reflow, MSL 1 compliant. Dimensions: 1.60 mm (L) × 0.80 mm (W) × 0.70 mm (H); pin pitch 0.65 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode (Line 1) | Connects to first protected signal line; reverse-biased during ESD event to clamp voltage to VBR/VC. |
| Pin 2 | Cathode (Line 2) | Connects to second protected signal line; electrically isolated from Pin 1 except through shared anode. |
| Pin 3 | Common Anode | Reference node tied to ground or supply rail; completes conduction path for both cathodes during overvoltage events. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-line protection in single SC−89 package | Reduces PCB area by ~50% vs. two discrete SOD-323 diodes; enables routing flexibility in tight I/O zones. |
| IEC61000−4−2 Level 4 compliance | Guarantees 8 kV contact / 15 kV air discharge immunity without external filtering or layout changes. |
| Low 1.0 µA max reverse leakage | Minimizes standby current draw in battery-powered USB, UART, or I²C interfaces with long sleep cycles. |
| AEC−Q101 qualified | Validated for automotive infotainment, body control, and ADAS sensor interfaces requiring zero-failure reliability. |
| Pb-free, Halogen-free, RoHS compliant | Meets global environmental regulations and enables direct use in consumer, medical, and industrial final assemblies. |

IC Role / Device Role / Timing Role: Low-leakage transient suppressor referenced to clean analog ground, placed before input RC filters. Use Value: Ensures <1.0 µA leakage prevents DC offset errors in high-impedance sensor paths, critical for sub-mV signal accuracy. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD5Z6.8T5G | Same SC−89 package, identical VRWM (4.5 V) and VBR (6.46–7.14 V), but lower Ppk (56 W) and higher VC (12.5 V @ 1 A). | Suitable for non-automotive consumer electronics where 8 kV ESD margin is sufficient and cost is prioritized. | Select when full 73 W surge rating is not required and BOM consolidation with existing ESZ-series parts is preferred. |
| CM1213A-03SO | 3-pin SOT-23 package, same dual common-anode topology, VRWM = 3.3 V, VBR = 4.5–5.1 V, VC = 11.5 V @ 1 A, Ppk = 60 W. | Better suited for 3.3 V logic rails; larger SOT-23 footprint increases PCB area by ~2.5× vs. SC−89. | Choose for legacy designs already using SOT-23 footprints or where tighter VRWM margin for 3.3 V systems is needed. |
Compared with ESD5Z6.8T5G and CM1213A-03SO, NZL6V8AXV3T1 provides the highest peak pulse power (73 W) and lowest leakage (<1.0 µA) in the smallest SC−89 footprint-making it optimal for next-gen automotive and space-constrained industrial I/O protection where reliability and miniaturization are co-prioritized.

FAQ
What is the maximum working voltage supported by NZL6V8AXV3T1?
The NZL6V8AXV3T1 has a working peak reverse voltage (VRWM) of 4.5 V, meaning it can safely protect signal lines operating continuously up to this voltage without entering breakdown. This makes NZL6V8AXV3T1 ideal for 3.3 V systems with margin, but unsuitable for unprotected 5 V rails unless derated per thermal conditions.
Does NZL6V8AXV3T1 support bidirectional ESD protection?
The NZL6V8AXV3T1 is inherently unidirectional due to its common-anode architecture, but can be used in bidirectional configurations with external biasing-e.g., connecting Pin 3 to VCC instead of GND. However, its specified parameters (VBR, VC, IPP) apply only to unidirectional operation; true bidirectional performance requires verification per application circuit.
Is NZL6V8AXV3T1 qualified for automotive applications?
Yes, NZL6V8AXV3T1 is AEC−Q101 qualified and PPAP capable, with full test documentation available from onsemi. Its construction, thermal performance, and ESD robustness meet automotive requirements for modules deployed in cabin, chassis, and powertrain domains where ambient temperatures reach +125°C.
What is the clamping voltage of NZL6V8AXV3T1 during an ESD event?
The NZL6V8AXV3T1 clamps to a maximum of 11.9 V at 1 A peak surge current (IPP), per IEC61000−4−2 8/20 µs waveform. This value is measured with 5 mA DC test current for VBR and confirmed across production lots; actual clamping may vary slightly depending on PCB layout parasitics and trace inductance.
Can NZL6V8AXV3T1 replace NZL5V6AXV3T1 in the same PCB layout?
Yes, NZL6V8AXV3T1 shares identical SC−89 package dimensions, pinout (Pin 1 cathode, Pin 2 cathode, Pin 3 anode), and solder footprint with NZL5V6AXV3T1, enabling drop-in replacement. However, its higher VBR (6.46–7.14 V vs. 5.32–5.88 V) and VRWM (4.5 V vs. 3.0 V) require validation against the protected signal's voltage margins and noise tolerance.
