Product details
Overview
NZQA6V8XV5T1G from onsemi is a quad unidirectional ESD protection diode array in SOT-553 package, featuring 6.8 V breakdown voltage (min 6.46 V, max 7.14 V @ 1 mA), 12.5 V clamping voltage at 8 A peak pulse current, 0.1 µA reverse leakage at 4.3 V, and 70 pF typical capacitance per diode at 0 V bias. It protects four independent data or signal lines in space-constrained interfaces such as USB 2.0, HDMI, and industrial I/O.
For engineers reviewing the NZQA6V8XV5T1G datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage margin vs. IC I/O rail, line-to-line capacitance impact on signal integrity, IEC 61000-4-2 Level 4 compliance, and common-anode quad configuration for compact board layout.
Technical Context
This device implements a monolithic silicon quad ESD suppressor with common-anode topology-four cathodes (pins 1, 3, 4, 5) tied to individual protected lines and a shared anode (pin 2). Its design targets transient suppression of electrostatic discharge events up to ±30 kV contact discharge per IEC 61000-4-2 Level 4.
Electrical behavior is defined by sharp Zener-like breakdown at 6.8 V nominal, low dynamic impedance under surge (VC = 12.5 V @ IPP = 8 A), and minimal parasitic capacitance (70 pF) to preserve high-speed signal fidelity without requiring series impedance tuning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage | 6.46–7.14 V @ 1 mA - ensures reliable turn-on before damage to 5 V or 3.3 V interface ICs |
| Clamping Voltage | 12.5 V @ 8 A peak pulse - limits transient stress on downstream receivers during ESD events |
| Reverse Leakage | 0.1 µA @ 4.3 V - negligible DC loading on high-impedance sensor or analog signal paths |
| Capacitance | 70 pF @ 0 V, 1 MHz - compatible with USB 2.0 (480 Mbps) and RS-485 signaling without distortion |
| ESD Rating | ±30 kV contact / ±30 kV air per IEC 61000-4-2 Level 4 - meets industrial and medical equipment immunity requirements |
| Package | SOT-553 (1.6 × 1.2 × 0.55 mm) - enables four-line protection in < 2 mm² footprint, ideal for portable electronics |
Pinout & Package
SOT-553 (Case 463B) is a 5-pin, surface-mount, Pb-free thermoset plastic package with MSL1 rating for 260 °C reflow. Pin 2 is the common anode; pins 1, 3, 4, and 5 are individual cathodes for four protected lines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode 1 | Protected line #1 - connects to I/O trace requiring ESD clamping to common anode |
| 2 | Common Anode | Shared return path to ground or negative rail - must be routed with low-inductance connection |
| 3 | Cathode 2 | Protected line #2 - electrically isolated from other cathodes; supports independent signal routing |
| 4 | Cathode 3 | Protected line #3 - identical electrical characteristics to pins 1 and 3; no internal coupling |
| 5 | Cathode 4 | Protected line #4 - completes quad configuration; enables single-package protection of full differential pair + control lines |
Key Features
| Feature | Design Value |
|---|---|
| Quad unidirectional configuration | Four independent cathodes with shared anode - eliminates need for four discrete diodes and reduces PCB area by >60% |
| Low clamping voltage | 12.5 V @ 8 A - maintains safe margin below absolute maximum ratings of 3.3 V/5 V logic I/O |
| 70 pF capacitance per channel | Preserves signal rise time in USB 2.0 and CAN FD applications - avoids data eye closure or jitter accumulation |
| IEC 61000-4-2 Level 4 compliance | Validated ±30 kV contact discharge performance - satisfies EN 61000-6-2 and IEC 61326-1 immunity mandates |
