Product details
Overview
NUP1301QA-Q from Nexperia is an ultra-low-capacitance ESD protection array in a DFN1010D-3 (SOT1215) package, designed to protect a single high-speed signal line in rail-to-rail configuration. It delivers 2.3 pF typical diode capacitance, 30 kV IEC 61000-4-2 contact ESD robustness, and clamps transients to ≤10 V at 11 A (8/20 µs), making it suitable for I²C-bus, antenna power supply, and Class-D amplifier interfaces.
For engineers reviewing the NUP1301QA-Q datasheet, NUP1301QA-Q pinout, NUP1301QA-Q application, or NUP1301QA-Q equivalent, this device is selected for high-frequency signal integrity preservation, automotive-grade transient immunity, and minimal PCB footprint in space-constrained layouts.
Technical Context
The NUP1301QA-Q integrates two back-to-back diodes in a three-terminal rail-to-rail topology: Pin 1 (A1) connects to GND, Pin 2 (K2) to VCC, and Pin 3 (K1/A2) to the protected signal line. Transient energy above the forward voltage (~0.715 V at 1 mA) is shunted either to ground or supply rail depending on polarity.
Its dynamic resistance is 0.55 Ω (positive TLP) and 0.3 Ω (negative TLP), enabling fast clamping response with low voltage overshoot. The device meets AEC-Q101 qualification and supports operation from −55 °C to +150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Diode capacitance (Pin 3 to Pins 1 & 2) | 2.3 pF typ - preserves signal integrity on high-speed lines like I²C and audio interfaces |
| ESD rating (IEC 61000-4-2 contact) | ±30 kV - exceeds Level 4 immunity for automotive and industrial connectors |
| Clamping voltage (IPPM = 11 A) | ≤10 V - limits voltage stress on downstream ICs during surge events |
| Reverse leakage current (VR = 25 V) | 7–30 nA - negligible loading on low-power analog or sensor circuits |
| Peak pulse current (8/20 µs) | 11 A - handles high-energy surges per IEC 61000-4-5 |
| Breakdown voltage | 100 V min - ensures stable operation under 80 V reverse bias conditions |
| AEC-Q101 qualified | Yes - validated for automotive electronics including infotainment and ADAS sensor interfaces |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor ESD9X3.3S | 3.3 V working voltage; 12 pF capacitance; 3 A peak pulse rating | Higher capacitance limits use to sub-MHz signals; lower surge rating suits consumer-grade USB ports | Select when lower clamping voltage (5.5 V @ 1 A) is prioritized over high-speed signal fidelity |
| Vishay VEML6030X01 | Photodiode + integrated ESD protection; 15 pF capacitance; not AEC-Q101 qualified | Designed specifically for ambient light sensing; lacks rail-to-rail topology and automotive validation | Only applicable where combined optical sensing and basic ESD protection are required in non-automotive designs |
Compared with ESD9X3.3S and VEML6030X01, the NUP1301QA-Q uniquely combines automotive qualification, rail-to-rail architecture, and sub-3 pF capacitance-enabling robust protection of high-speed automotive interfaces without signal degradation.

FAQ
What is the maximum recommended PCB trace length between NUP1301QA-Q and the protected connector?
For optimal ESD suppression, place the NUP1301QA-Q within 2 mm of the connector entry point. Longer traces increase inductance, raising clamping voltage during fast transients. Layout guidelines specify minimizing the loop area between Pin 1 (GND), Pin 2 (VCC), and Pin 3 (signal) to preserve sub-10 V clamping performance at 30 kV ESD events.
Can NUP1301QA-Q be used to protect differential high-speed lines like USB 2.0 or HDMI?
No-NUP1301QA-Q is a single-line rail-to-rail protector with asymmetric internal diode pairing (Pin 1→GND, Pin 2→VCC). It lacks matched capacitance and common-mode rejection needed for differential pairs. For USB 2.0, use dedicated dual-channel arrays such as NUP4201MR6T1G with matched 0.8 pF channels.
Does NUP1301QA-Q require external decoupling capacitors on VCC?
No external capacitor is required for ESD function, but a local 100 nF ceramic capacitor between Pin 2 (VCC) and Pin 1 (GND) is strongly recommended. This stabilizes the supply rail during high-current clamping events and prevents voltage droop that could affect upstream regulators or logic thresholds.
How does thermal performance change when operating near the 150 °C junction limit?
At Tj = 150 °C, reverse leakage rises to 150 µA (vs. 30 nA at 25 °C), increasing standby power in battery-critical applications. Dynamic resistance also increases slightly, raising clamping voltage by ~0.5 V at 11 A. Derating is advised above 125 °C ambient for sustained surge duty cycles.
