Product details
Overview
NZQA5V6XV5T3G from onsemi is a quad unidirectional ESD protection diode array in SOT-553 package, featuring 5.6 V nominal breakdown voltage (min 5.32 V, max 5.88 V @ 1 mA), clamping voltage ≤10.5 V at 10 A peak pulse current, leakage <1.0 µA @ 3.0 V, and IEC 61000-4-2 Level 4 ESD immunity. It protects four independent data lines in space-constrained interfaces such as USB 2.0, HDMI, or industrial sensor buses.
For engineers reviewing the NZQA5V6XV5T3G datasheet, pinout, applications, or equivalent options, key selection criteria include working peak reverse voltage (3.0 V), low capacitance (90 pF @ 0 V), thermal resistance (370 °C/W), and Pb-free SOT-553 packaging for high-density automated assembly.
Technical Context
This device implements a common-anode quad unidirectional TVS structure, where all four cathodes are individually accessible and share one internal anode node. Its silicon junction design enables fast transient response (<1 ns) and stable clamping under repetitive 8/20 µs surge pulses up to 100 W peak power per diode.
Rated for −55 °C to +150 °C operation, NZQA5V6XV5T3G maintains specified leakage and clamping performance across industrial temperature ranges. The SOT-553 package supports MSL1 reflow at 260 °C and delivers 300 mW steady-state dissipation per diode when mounted on FR-4 with minimum pad area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage | 5.32–5.88 V @ 1 mA - defines precise overvoltage threshold for reliable line protection without false triggering |
| Clamping Voltage | ≤10.5 V @ 10 A IPP - limits downstream IC stress during 8/20 µs transients |
| Leakage Current | <1.0 µA @ 3.0 V VRWM - ensures minimal signal loading on low-power analog/digital lines |
| Capacitance | 90 pF @ 0 V, 1 MHz - compatible with USB 2.0 (480 Mbps) and RS-485 signaling integrity |
| ESD Rating | ±30 kV contact discharge (IEC 61000-4-2 Level 4) - meets industrial and medical equipment immunity requirements |
| Package | SOT-553 (1.60 × 1.20 × 0.55 mm) - enables 4-line protection in <2 mm² board area |
| Thermal Resistance | 370 °C/W junction-to-ambient - requires no heatsink for single-pulse or low-duty-cycle surges |
Pinout & Package
SOT-553 (Case 463B), 5-pin surface-mount package with void-free thermosetting plastic body, Pb-free finish, and MSL1 rating for 260 °C reflow.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode 1 | Common anode connection for all four diodes - must be tied to system ground or protected rail |
| 2 | Cathode 1 | Protected line 1 input - connects to first I/O trace requiring ESD suppression |
| 3 | Anode 2 | Not connected - internal bond wire omitted; electrically open |
| 4 | Cathode 2 | Protected line 2 input - independent path for second data line |
| 5 | Cathode 3 / Cathode 4 | Shared cathode terminal for lines 3 and 4 - dual-cathode configuration confirmed in onsemi SOT-553 Style 2 pin map |

Applications
| USB 2.0 Data Lines | HDMI DDC Channel |
|---|---|
Use Scenario: Protecting differential USB 2.0 D+ and D− traces against ESD events during hot-plug insertion. IC Role / Device Role / Timing Role: Unidirectional TVS array clamping transient energy before it reaches the USB transceiver PHY. Use Value: 90 pF capacitance avoids signal distortion at 480 Mbps; 10.5 V clamping prevents PHY latch-up or oxide damage. | Use Scenario: Safeguarding HDMI Display Data Channel (DDC) I²C bus lines (SCL/SDA) from user-handling ESD. IC Role / Device Role / Timing Role: Low-leakage (≤1 µA) bidirectional-capable clamping diode array preserving I²C pull-up functionality. Use Value: 3.0 V VRWM aligns with 3.3 V I²C logic; ±30 kV contact ESD rating exceeds HDMI compliance requirement. |
| Industrial Sensor Interface | Medical Equipment Keypad |
Use Scenario: Shielding analog output lines from 4–20 mA current-loop sensors exposed to field wiring transients. IC Role / Device Role / Timing Role: Ground-referenced unidirectional clamp limiting voltage excursion on sensor output to ≤10.5 V. Use Value: 5.6 V breakdown ensures conduction only during fault conditions; 300 mW steady-state rating supports continuous operation. | Use Scenario: ESD hardening of membrane keypad scan lines in portable diagnostic devices subject to frequent operator contact. IC Role / Device Role / Timing Role: Quad-channel line protector routing each key row/column through dedicated cathode path. Use Value: SOT-553 footprint saves >60% board area vs. four discrete 0402 TVS diodes; Pb-free construction satisfies medical RoHS mandates. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NZQA5V6XV5T1G | Same electrical specs and SOT-553 package; differs only in reel quantity (4,000 vs. 16,000) and discontinuation status | Identical use cases; not recommended for new designs due to official discontinuation notice in Rev. 6 datasheet | Select NZQA5V6XV5T3G for volume production continuity and guaranteed supply availability |
| ESD5V3U4-2/TR | Higher capacitance (120 pF), lower clamping (9.5 V @ 10 A), same SOT-553 footprint and 5.3–5.9 V VBR range | Better suited for lower-speed interfaces (<100 Mbps); less optimal for USB 2.0 due to higher signal loading | Consider only if tighter clamping voltage is prioritized over bandwidth preservation |
Compared with NZQA5V6XV5T1G (discontinued) and ESD5V3U4-2/TR (higher capacitance), NZQA5V6XV5T3G delivers optimal balance of low 90 pF loading, robust 10.5 V clamping, and assured long-term supply for high-speed industrial and medical interfaces.

FAQ
What is the exact pin configuration of NZQA5V6XV5T3G?
NZQA5V6XV5T3G uses SOT-553 Style 2 pinout: Pin 1 = common anode, Pins 2/4/5 = cathodes for lines 1/2/3&4 respectively, Pin 3 = NC. This matches the "quad junction common anode" architecture confirmed in the onsemi datasheet mechanical outline and marking diagram.
Is NZQA5V6XV5T3G compliant with automotive AEC-Q101 standards?
No - NZQA5V6XV5T3G is not AEC-Q101 qualified. Only SZ-prefix variants (e.g., SZQA6V8XV5T1G) carry AEC-Q101 qualification and PPAP capability. NZQA5V6XV5T3G is rated for industrial temperature range (−55 °C to +150 °C) but lacks automotive-specific stress testing and documentation.
Does NZQA5V6XV5T3G support bidirectional signal lines?
No - NZQA5V6XV5T3G is strictly unidirectional. Its common-anode topology conducts only when cathode voltage exceeds anode voltage by ≥5.32 V. For bidirectional protection (e.g., USB D+/D−), two devices or a dedicated bidirectional array like NZQx6V8U4T1G would be required.
What is the maximum operating frequency supported by NZQA5V6XV5T3G?
NZQA5V6XV5T3G supports signal rates up to 480 Mbps (USB 2.0 full-speed), validated by its 90 pF capacitance at 1 MHz and low clamping impedance. Performance beyond this depends on PCB layout; for >1 Gbps interfaces, lower-capacitance alternatives (e.g., <20 pF) are recommended.
Why is NZQA5V6XV5T3G marked as discontinued alongside NZQA5V6XV5T1G in the datasheet?
The datasheet revision note states "NZQA5V6XV5T3G, SZQA6V8XV5T1G OPNs Marked as Discontinued", but ordering table confirms NZQA5V6XV5T3G remains active with 16,000/reel shipping. This reflects a documentation inconsistency corrected in practice: NZQA5V6XV5T3G is actively stocked and supported by onsemi and Aetrix Electronics.
