Product details
Overview
NZQA6V2XV5T1 from onsemi is a quad unidirectional ESD protection diode array in SOT-553 package, featuring 6.2 V nominal breakdown voltage (VBR), 4.0 V working peak reverse voltage (VRWM), 11.5 V clamping voltage at 9 A peak pulse current (IPP), and 0.5 µA max reverse leakage at VRWM. It protects four I/O lines in space-constrained interfaces such as USB 2.0 data lines in portable medical monitors.
For engineers reviewing the NZQA6V2XV5T1 datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage margin vs. IC I/O rail, capacitance impact on signal integrity, IEC 61000-4-2 Level 4 compliance, and common-anode quad layout for compact PCB routing.
Technical Context
This device implements a monolithic silicon quad Zener-based transient voltage suppressor with common-anode configuration - all four cathodes are individually accessible while sharing one internal anode node. Each channel provides unidirectional ESD clamping without series resistance or integrated capacitance tuning.
It meets IEC 61000-4-2 Level 4 (±8 kV contact, ±15 kV air) and delivers 100 W peak pulse power (8/20 µs waveform) with thermal derating to 2.7 mW/°C above 25°C ambient. Junction temperature remains within safe limits up to +150°C under single-diode power dissipation of 300 mW.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR @ 1 mA | 5.89–6.51 V: Ensures reliable turn-on before damage to 3.3 V or 5 V logic I/O pins |
| VRWM | 4.0 V: Maximum continuous reverse voltage tolerated without leakage degradation |
| VC @ IPP=9 A | 11.5 V max: Clamping level that keeps protected IC pins below absolute maximum ratings |
| IR @ VRWM | 0.5 µA max: Negligible DC loading on high-impedance sensor or reference lines |
| CJ @ 0 V, 1 MHz | 80 pF typical per diode: Low enough for USB 2.0 (480 Mbps) signal integrity with proper layout |
| PPK | 100 W (8/20 µs): Handles multiple ESD strikes without parametric shift or failure |
| TJmax | +150°C: Supports operation in sealed industrial enclosures with limited airflow |
Pinout & Package
SOT-553 (Case 463B) is a 5-lead surface-mount plastic package measuring 1.50–1.70 mm × 1.10–1.30 mm × 0.50–0.60 mm, lead-free, MSL1 rated for 260°C reflow, optimized for automated placement and high-density routing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode 1 | ESD clamp path for first protected line (e.g., USB D+) |
| 2 | Anode (common) | Shared return node tied to system ground or low-impedance chassis plane |
| 3 | Cathode 2 | ESD clamp path for second protected line (e.g., USB D−) |
| 4 | Cathode 3 | ESD clamp path for third protected line (e.g., UART TX) |
| 5 | Cathode 4 | ESD clamp path for fourth protected line (e.g., UART RX) |
Key Features
| Feature | Design Value |
|---|---|
| Quad unidirectional configuration | Four independent clamping paths share one anode terminal, reducing board area by ~75% vs. discrete diodes |
| IEC 61000-4-2 Level 4 compliance | Validated for ±8 kV contact and ±15 kV air discharge - meets end-equipment immunity requirements for Class B medical devices |
| Low 80 pF junction capacitance | Enables use on 480 Mbps USB 2.0 differential pairs without measurable eye diagram degradation |
| 0.5 µA leakage @ 4.0 V | Preserves accuracy in precision analog front-ends (e.g., thermistor or RTD measurement circuits) |
| SOT-553 footprint | Compatible with standard 0.5 mm pitch pick-and-place equipment and reflow profiles; no special assembly process required |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD5Z6.0T1G | Single-channel SOD-523; 6.0 V VBR, 12.5 V VC @ 5 A, 100 pF | Requires four separate placements; higher capacitance limits USB 2.0 use | Prefer when board area allows discrete layout or only one line needs protection |
| CM1224-04SO | Quad SOT-23-6; 5.5 V VRWM, 14 V VC @ 8 A, 15 pF per line | Lower capacitance but higher clamping voltage; different pinout (anode not shared) | Choose when ultra-low capacitance is critical and layout supports non-common-anode routing |
Compared with ESD5Z6.0T1G and CM1224-04SO, NZQA6V2XV5T1 offers the tightest VBR tolerance (±5%), lowest clamping voltage among quad common-anode arrays, and optimal balance of leakage, capacitance, and surge robustness for cost-sensitive industrial USB designs.

FAQ
What is the exact breakdown voltage range for NZQA6V2XV5T1?
The NZQA6V2XV5T1 has a specified breakdown voltage (VBR) range of 5.89 V to 6.51 V at 1 mA test current, with a nominal value of 6.2 V. This range ensures consistent triggering behavior across manufacturing lots and temperature variations, supporting reliable protection of 3.3 V and 5 V logic rails without premature conduction.
Does NZQA6V2XV5T1 support bidirectional ESD protection?
No, NZQA6V2XV5T1 is a unidirectional ESD protection device with a common-anode configuration. It clamps positive transients on cathode lines to ground but does not protect against negative-going surges beyond the forward voltage drop (~1.3 V). For bidirectional protection, a complementary array or external series resistor must be used.
What is the maximum clamping voltage of NZQA6V2XV5T1 under ESD stress?
The maximum clamping voltage (VC) of NZQA6V2XV5T1 is 11.5 V at 9 A peak pulse current (IPP), measured using the 8/20 µs waveform. This value defines the upper voltage limit imposed on protected lines during IEC 61000-4-2 Level 4 contact discharge events, ensuring downstream ICs remain within safe operating voltage margins.
Can NZQA6V2XV5T1 be used on high-speed differential signals like HDMI or PCIe?
No - NZQA6V2XV5T1 is not recommended for HDMI or PCIe due to its 80 pF typical junction capacitance per diode, which would severely degrade signal integrity at multi-Gbps data rates. It is validated for USB 2.0 (480 Mbps) and lower-speed interfaces such as UART, I²C, and RS-232 where capacitance impact is manageable with proper layout.
Is NZQA6V2XV5T1 RoHS-compliant and lead-free?
Yes, NZQA6V2XV5T1 is 100% lead-free and complies with RoHS Directive 2011/65/EU. Its SOT-553 package is rated MSL1 with a peak reflow temperature of 260°C, making it compatible with standard lead-free assembly processes without moisture sensitivity concerns.
