Product details
Overview
NUP1301QAZ from Nexperia is an ultra-low-capacitance ESD protection array in a DFN1010D-3 (SOT1215) package, designed for rail-to-rail protection of a single high-speed signal line. It delivers 2.3 pF typical diode capacitance, 30 kV IEC 61000-4-2 contact ESD robustness, and 11 A peak pulse current (8/20 µs), making it suitable for I²C-bus, antenna power supply, and analog audio interface protection.
For engineers reviewing the NUP1301QAZ datasheet, NUP1301QAZ pinout, NUP1301QAZ application, or NUP1301QAZ equivalent, key selection criteria include rail-to-rail clamping configuration, sub-3 pF capacitance across pins 1–3 and 2–3, low 30 nA reverse leakage at 25 V, AEC-Q101 qualification, and DFN1010D-3 footprint compatibility with high-density PCB layouts.
Technical Context
The NUP1301QAZ integrates two back-to-back diodes in a common-cathode/anode configuration (Pin 3 = shared terminal; Pins 1 & 2 = opposing terminals), enabling bidirectional transient clamping between signal line and both rails (GND and VCC). Its architecture supports fast response to ±8 kV ESD pulses per IEC 61000-4-2 while maintaining low dynamic resistance (0.3–0.55 Ω) under 10 A TLP stress.
Clamping occurs at ≤10 V under 11 A surge (IEC 61000-4-5, 8/20 µs), with breakdown voltage ≥100 V and forward voltage ≤855 mV at 10 mA. The device operates across −55 °C to +150 °C ambient and is qualified to AEC-Q101 for automotive-grade reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

IC Role / Device Role / Timing Role: Point-of-entry ESD guard on MCU pins connected to door handle sensors or LIN bus transceivers. Use Value: AEC-Q101 qualification guarantees operation at −40 °C to +125 °C; 11 A surge rating covers load-dump coupling events. |
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 | Single-line, 3.3 V clamping; 0.5 pF capacitance; SOD-923 package (larger footprint) | Optimized for 3.3 V logic only; lacks rail-to-rail configuration - requires separate GND/VCC connections | Select when lower capacitance (<0.6 pF) is critical and system uses fixed 3.3 V rails with dedicated ground return. |
| Vishay VEML6030X01 | Not applicable - optical sensor IC, not ESD protection device | N/A | Not a valid alternative; excluded due to functional mismatch. |
Compared with ESD9X3.3S, NUP1301QAZ provides rail-to-rail clamping flexibility and AEC-Q101 qualification but trades 0.2 pF higher capacitance for broader voltage range (up to 80 V reverse) and integrated dual-diode topology - ideal for mixed-voltage automotive subsystems.

FAQ
What is the maximum continuous reverse voltage rating for NUP1301QAZ?
The absolute maximum reverse voltage (VR) is 80 V at 25 °C ambient, verified per IEC 60134 limiting values. This allows safe integration into 24 V automotive systems and 48 V telecom power domains without risk of steady-state breakdown. Derating applies above 25 °C per the datasheet's thermal characteristics curve.
Can NUP1301QAZ protect bidirectional data lines like I²C without external biasing?
Yes - its internal back-to-back diode structure (Pin 3 as common terminal, Pins 1 and 2 tied to GND and VCC) enables true rail-to-rail clamping. No external bias resistors or voltage references are needed, preserving I²C pull-up functionality while suppressing ±30 kV ESD transients on both SDA and SCL simultaneously.
How does the DFN1010D-3 package impact PCB layout and thermal performance?
The 1.1 × 1.0 mm DFN1010D-3 package features solderable side pads that enhance thermal dissipation and mechanical reliability. Layout requires strict adherence to Nexperia's recommended footprint (0.75 mm pad width, 0.3 mm spacing), placement within 2 mm of the protected connector, and direct connection to internal ground/power planes via multiple vias to minimize inductance in the transient return path.
Is NUP1301QAZ compatible with lead-free reflow profiles?
Yes - it is qualified for standard JEDEC J-STD-020D lead-free reflow, with peak temperature up to 260 °C. The DFN1010D-3 package supports both Type 3 and Type 4 solder pastes, and Nexperia provides detailed stencil design guidelines (0.125 mm thickness, 1:1 area ratio) to ensure void-free solder joints and optimal thermal transfer during assembly.
