Product details
Overview
NZQA6V8XV5T1 from onsemi is a quad unidirectional ESD protection diode array in SOT-553 package, featuring 6.8 V breakdown voltage (VBR @ 1 mA), 12.5 V clamping voltage (VC) at 8 A peak pulse current, and 0.1 µA reverse leakage at 4.3 V working voltage - deployed for USB data line, HDMI interface, and portable display port surge suppression.
For engineers reviewing the NZQA6V8XV5T1 datasheet, pinout, applications, or equivalent options, key selection criteria include IEC 61000-4-2 Level 4 ESD rating, 70 pF typical capacitance per diode at 0 V, low forward voltage (1.3 V @ 200 mA), and common-anode quad configuration enabling compact four-line protection without discrete layout overhead.
Technical Context
This device implements a monolithic silicon quad ESD suppressor with common-anode topology, where pins 2–5 serve as cathodes and pin 1 as shared anode - enabling simultaneous transient clamping across four independent signal paths. Its design targets fast response to sub-nanosecond ESD events while maintaining low capacitance to preserve high-speed signal integrity.
It meets IEC 61000-4-2 Level 4 (±15 kV air / ±8 kV contact) and MIL-STD-883C Method 3015-6, with thermal derating defined by RJA = 370 °C/W and TJmax = 150 °C. Peak power dissipation is rated at 100 W (8/20 µs pulse), supporting robust transient immunity in space-constrained interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR @ 1 mA | 6.46–7.14 V - ensures reliable turn-on before downstream IC damage threshold in 5 V–6 V logic systems |
| VC @ IPP = 8 A | 12.5 V max - limits voltage seen by protected IC during 8 A transient, compatible with 13.2 V absolute max ratings |
| CJ @ 0 V, 1 MHz | 70 pF typical per diode - low enough for <1 Gbps differential signaling without measurable eye degradation |
| IR @ VRWM = 4.3 V | 0.1 µA max - negligible loading on high-impedance sensor or reference lines |
| ESD Rating | IEC 61000-4-2 Level 4 (±15 kV air / ±8 kV contact) - satisfies industrial and consumer end-equipment compliance requirements |
| PPK | 100 W (8/20 µs) - handles single-event surges up to 100 W without failure under specified waveform |
| Package | SOT-553 (Case 463B) - 1.6 × 1.2 × 0.6 mm footprint enables placement adjacent to connectors on dense PCBs |
Pinout & Package
SOT-553 is a 5-lead surface-mount plastic package (Case 463B) with void-free transfer-molded construction, MSL1 rating, and lead-free finish - optimized for automated reflow assembly and high-density routing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Common Anode | Shared anode connection for all four diodes; must be tied to system ground or local reference plane |

Applications
| USB 2.0 Data Lines | HDMI TMDS Channels |
|---|---|
Use Scenario: Protecting D+ and D− lines of USB 2.0 ports against ESD events during cable insertion or handling. IC Role / Device Role / Timing Role: Transient voltage suppressor placed directly at connector, clamping fast-rising ESD pulses before they reach USB transceiver IC. Use Value: 70 pF capacitance avoids signal rise-time degradation; 12.5 V clamping ensures USB PHY remains within its 13.2 V absolute maximum rating. | Use Scenario: Shielding three TMDS data pairs and one clock pair in HDMI 1.4 interfaces from contact discharge near panel connectors. IC Role / Device Role / Timing Role: Quad ESD clamp applied per TMDS lane using shared-anode grounding to minimize ground bounce during multi-line discharge. Use Value: Common-anode topology reduces ground loop inductance; 6.8 V VBR aligns with HDMI receiver input thresholds for early conduction. |
| Portable DisplayPort Interfaces | Industrial Sensor Signal Lines |
Use Scenario: Safeguarding DisplayPort AUX CH and HPD lines in thin client docking stations exposed to frequent hot-plug cycles. IC Role / Device Role / Timing Role: Low-capacitance ESD protector mounted within 3 mm of DP connector, preserving AUX channel timing margins. Use Value: 0.1 µA leakage prevents false HPD detection; 1.3 V forward voltage ensures minimal impact on 3.3 V logic levels. | Use Scenario: Protecting 4–20 mA current-loop sensor outputs and analog voltage inputs in factory automation modules. IC Role / Device Role / Timing Role: Bidirectional clamping (via external series resistor + NZQA6V8XV5T1) for overvoltage transients on isolated analog front-ends. Use Value: 6.8 V breakdown matches typical 5 V rail-based op-amp supply headroom; low leakage avoids offset error accumulation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD5V3U4-2/TR | Lower VBR (5.3 V min), higher CJ (100 pF), same SOT-553 package | Better suited for 3.3 V I/O rails; less ideal for 5 V tolerant interfaces due to earlier conduction | Select when protecting 3.3 V logic with tighter clamping margin and acceptable capacitance trade-off |
| TPD4E001DPYR | Higher VBR (6.9 V typ), lower CJ (5.5 pF), same 4-channel common-anode SOT-553 | Optimized for >3 Gbps differential links (e.g., USB 3.2 Gen 1); requires tighter layout control for ESD return path | Select when ultra-low capacitance is mandatory and 12.8 V clamping is acceptable for downstream IC rating |
Compared with ES5V3U4-2/TR and TPD4E001DPYR, NZQA6V8XV5T1 offers balanced clamping voltage (12.5 V), moderate capacitance (70 pF), and proven compatibility with 5 V–6 V interface rails - making it optimal for cost-sensitive industrial and consumer USB/HDMI designs where strict GHz-speed constraints do not apply.

FAQ
What is the breakdown voltage range of NZQA6V8XV5T1?
The NZQA6V8XV5T1 has a guaranteed breakdown voltage (VBR) range of 6.46 V to 7.14 V at 1 mA test current, with a nominal value of 6.8 V. This specification ensures consistent turn-on behavior across production lots and temperature ranges, allowing designers to confidently size upstream series impedance and verify margin against protected IC absolute maximum ratings. The NZQA6V8XV5T1's VBR is validated per the onsemi datasheet Rev. 1 (April 2005).
Does NZQA6V8XV5T1 support IEC 61000-4-2 Level 4 ESD protection?
Yes, NZQA6V8XV5T1 is certified to meet IEC 61000-4-2 Level 4 for both air discharge (±15 kV) and contact discharge (±8 kV). This rating is confirmed in the official onsemi datasheet and verified through standardized testing per the specification. The NZQA6V8XV5T1 achieves this performance using monolithic silicon junction design and optimized package parasitics - no external components required for basic compliance.
What is the maximum clamping voltage of NZQA6V8XV5T1 at 8 A peak pulse current?
The maximum clamping voltage (VC) of NZQA6V8XV5T1 is 12.5 V when subjected to an 8 A peak pulse current (IPP) under 8/20 µs waveform conditions. This value defines the upper voltage limit imposed on protected lines during worst-case ESD events and is critical for ensuring downstream ICs remain within their absolute maximum ratings. The NZQA6V8XV5T1 maintains this clamping performance across its full operating temperature range.
Can NZQA6V8XV5T1 be used for bidirectional signal lines like RS-485?
No, NZQA6V8XV5T1 is a unidirectional ESD suppressor with common-anode configuration - it conducts only when cathodes are driven positive relative to the anode. For true bidirectional protection (e.g., RS-485 differential pairs), external series resistors and back-to-back diode arrangements or purpose-built bidirectional arrays are required. The NZQA6V8XV5T1 datasheet explicitly specifies unidirectional operation and does not characterize reverse conduction behavior.
What is the typical junction capacitance of NZQA6V8XV5T1 per channel?
The typical junction capacitance (CJ) of NZQA6V8XV5T1 is 70 pF per diode at 0 V bias and 1 MHz, as measured per the onsemi datasheet. This value is critical for high-speed interface design - it allows safe deployment on USB 2.0 (480 Mbps) and HDMI 1.4 TMDS lanes without measurable eye diagram closure. The NZQA6V8XV5T1's capacitance remains stable across process and temperature variations due to monolithic integration.
