Product details
Overview
NZL7V5AXV3T1G from onsemi is a dual common-anode ESD protection diode in SC-89 package, rated for 7.5 V breakdown voltage (VBR), 13.5 V clamping voltage (VC) at 1.0 A surge, and 5.0 nA reverse leakage at 5.0 V VRWM. It delivers Class N ESD immunity (>16 kV HBM) and meets IEC61000-4-2 Level 4 (±10 kV contact/air), protecting two I/O lines in space-constrained interfaces like USB or GPIO.
For engineers reviewing the NZL7V5AXV3T1G datasheet, pinout, applications, or equivalent options, key selection criteria include unidirectional dual-line clamping performance, SC-89 footprint compatibility, low capacitance (<15 pF at 0 V), and automotive-grade AEC-Q101 qualification via SZ-prefix variants.
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 paths without cross-talk. Its unidirectional configuration supports line-to-ground transient suppression while maintaining <5.0 nA leakage at rated VRWM.
The SC-89 package enables board-level integration with 0.5 mm pitch, 1.60 × 0.85 mm footprint, and MSL 1 reflow capability up to 260 °C. Thermal resistance RJA is 525 °C/W on FR-5 board, limiting steady-state power dissipation to 240 mW at 25 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VBR) | 7.12–7.88 V @ IT = 5.0 mA - defines minimum trigger threshold for ESD clamping |
| Clamping Voltage (VC) | 13.5 V @ IPP = 1.0 A - maximum voltage seen by protected IC during 8/20 µs surge |
| Working Peak Reverse Voltage (VRWM) | 5.0 V - maximum continuous DC voltage applied without significant leakage |
| Reverse Leakage Current (IR) | <1.0 nA @ VRWM = 5.0 V - ensures minimal signal loading on high-impedance lines |
| ESD Rating (HBM) | >16 kV - exceeds Class N requirement for robust handling in manufacturing and field use |
| IEC61000-4-2 Level | Level 4 (±10 kV contact, ±10 kV air) - certified for industrial and medical equipment immunity |
| Capacitance (CJ) | 12 pF @ 0 V bias - low enough for USB 2.0 and SPI bus protection without signal integrity loss |
Pinout & Package
SC-89 (Case 463C, Style 4) is a 3-lead surface-mount package measuring 1.60 × 0.85 × 0.70 mm with 0.50 mm lead pitch and matte tin plating. It is void-free, UL 94 V-0 rated, and qualified for MSL 1 reflow.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode (Line 1) | Protected signal path #1 - connects to I/O line requiring clamping to ground |
| Pin 2 | Cathode (Line 2) | Protected signal path #2 - independent clamping node for second I/O line |
| Pin 3 | Anode | Common ground reference - ties both cathodes to system GND or TVS return path |
Key Features
| Feature | Design Value |
|---|---|
| Dual-line common-anode topology | Reduces PCB real estate by 50% vs. discrete diodes - one SC-89 replaces two SOD-523 devices |
| Low clamping voltage (13.5 V) | Ensures protected ICs remain within absolute maximum ratings during 1 A transients |
| Sub-1 nA leakage at 5 V | Preserves battery life and signal fidelity in always-on sensor and IoT interface circuits |
| AEC-Q101 qualified variant available | SZNZL7V5AXV3T1G supports automotive infotainment and ADAS subsystems with PPAP documentation |
| Pb-free, Halogen-free, RoHS compliant | Meets global environmental compliance mandates without derating or reliability trade-offs |
Applications
| USB 2.0 Data Line Protection | Industrial GPIO Interface |
|---|---|
Use Scenario: Protecting D+ and D− lines of embedded USB peripherals against ESD events during hot-plug or handling. IC Role / Device Role: Unidirectional line-to-ground transient voltage suppressor placed immediately before USB PHY. Use Value: Clamps surges to ≤13.5 V while adding only 12 pF capacitance - preserves signal rise time and eye diagram integrity. |

IC Role / Device Role: Dual-channel ESD clamp isolating two independent digital inputs from shared ground return. Use Value: Eliminates need for two separate diodes - reduces BOM count and layout complexity in dense control modules. |
| Medical Sensor Interface | Automotive Infotainment I/O |
Use Scenario: Shielding analog front-end inputs (e.g., ECG electrode connections) from electrostatic discharge in handheld diagnostic tools. IC Role / Device Role: Low-leakage (≤1 nA) bidirectional-capable clamp used in unidirectional mode for precision signal paths. Use Value: Prevents baseline shift or offset errors caused by leakage current while meeting IEC61000-4-2 Level 4 immunity. |
Use Scenario: Protecting touch controller I/O lines and display data buses in automotive center consoles exposed to human contact. IC Role / Device Role: AEC-Q101-compliant variant (SZNZL7V5AXV3T1G) deployed in harsh temperature environments (−40 to +125 °C). Use Value: Delivers validated reliability over full automotive temperature range with no derating required for clamping performance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NZL6V8AXV3T1G | Lower VBR (6.46–7.14 V), lower VC (11.9 V), same SC-89 package and pinout | Better suited for 3.3 V I/O rails where tighter clamping margin is critical | Select when protecting 3.3 V logic with stricter voltage headroom requirements |
| ESD5Z7.0T1G | Single-channel, same VBR/VC specs, SOD-523 package (larger footprint, higher inductance) | Requires two devices for dual-line protection; less space-efficient than NZL7V5AXV3T1G | Choose only if existing layout uses SOD-523 or requires asymmetric channel routing |
Compared with NZL6V8AXV3T1G and ESD5Z7.0T1G, the NZL7V5AXV3T1G provides optimal balance of 5.0 V VRWM headroom, dual-line integration, and 13.5 V clamping for 5 V tolerant interfaces - making it preferred for USB, HDMI CEC, and industrial control bus protection where board area and channel count are constrained.

FAQ
What is the maximum working voltage supported by NZL7V5AXV3T1G?
The NZL7V5AXV3T1G has a working peak reverse voltage (VRWM) of 5.0 V, meaning it can safely block up to 5.0 V DC or peak AC signals without entering conduction. This makes it ideal for protecting 5 V logic lines while providing sufficient margin below its 7.5 V nominal breakdown voltage. Exceeding 5.0 V continuously risks increased leakage and premature wear.
How does NZL7V5AXV3T1G differ from NZL5V6AXV3T1G in circuit behavior?
The NZL7V5AXV3T1G features a higher breakdown voltage (7.12–7.88 V) and clamping voltage (13.5 V) compared to NZL5V6AXV3T1G (5.32–5.88 V VBR, 10.1 V VC), making it better suited for 5 V systems with larger voltage margins. Both share identical SC-89 pinout and dual-cathode/common-anode topology, allowing direct layout reuse when upgrading protection level.
Is NZL7V5AXV3T1G suitable for bidirectional signal lines like USB D+ and D−?
Yes - although configured as unidirectional per channel, the NZL7V5AXV3T1G's dual-cathode/common-anode structure allows each cathode-to-anode path to clamp positive transients to ground. For true bidirectional protection, external series resistors or complementary placement may be needed, but its 12 pF capacitance and fast response make it widely deployed on USB 2.0 differential pairs without signal degradation.
Does NZL7V5AXV3T1G meet automotive qualification standards?
The base NZL7V5AXV3T1G is not AEC-Q101 qualified; however, its automotive-grade variant SZNZL7V5AXV3T1G is fully AEC-Q101 qualified and PPAP capable. That version includes enhanced process controls, extended temperature validation (−40 to +125 °C), and automotive-specific traceability - all documented in onsemi's official automotive product release.
What is the thermal derating behavior of NZL7V5AXV3T1G above 25 °C ambient?
The NZL7V5AXV3T1G dissipates 240 mW at 25 °C ambient on FR-5 board, with linear derating of 1.9 mW/°C above that temperature. At 85 °C ambient, usable power drops to approximately 126 mW. This must be considered when sizing traces and copper pour for sustained surge duty cycles or high-frequency transient repetition rates.
