Product details
Overview
NUP1301,215 from Nexperia is an ultra-low-capacitance ESD protection array in SOT23 package, designed for rail-to-rail protection of a single high-speed signal line (e.g., I²C, antenna supply, or analog audio). It delivers 0.6 pF typical diode capacitance, 30 kV IEC 61000-4-2 contact ESD rating, and clamps transients to ≤20 V at 11 A surge current.
For engineers reviewing the NUP1301,215 datasheet, NUP1301,215 pinout, NUP1301,215 application, or NUP1301,215 equivalent, key selection criteria include sub-1 pF capacitance for signal integrity, rail-to-rail clamping architecture, low leakage (<100 nA at 80 V), and compatibility with high-speed interfaces requiring minimal loading.
Technical Context
The NUP1301,215 implements a bidirectional rail-to-rail ESD clamp using two back-to-back diodes between I/O and GND/VCC. Transient energy above ~715 mV forward voltage is shunted either to ground (pin 1) or supply rail (pin 2), enabling low-voltage clamping without external biasing.
Its 8/20 µs surge rating of 11 A (PPPM = 220 W) and 30 kV IEC 61000-4-2 compliance are validated with pin 3 (I/O) stressed relative to pins 1+2 shorted. Thermal resistance Rth(j-a) is 500 K/W on FR4, supporting operation up to 150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 80 V repetitive peak reverse voltage - ensures safe operation across industrial and telecom supply rails. |
| Cd | 0.6 pF typical at 1 MHz, 0 V - preserves signal integrity on >100 MHz data lines like USB 2.0 or HDMI DDC. |
| IR | ≤100 nA at 80 V, 25 °C - prevents DC loading on sensitive analog or microcontroller I/O pins. |
| VCL | ≤20 V at IPPM = 11 A - limits transient overvoltage to protect downstream CMOS inputs rated ≤24 V. |
| ESD Rating | 30 kV per IEC 61000-4-2 contact discharge - exceeds Level 4 immunity for handheld and interface ports. |
| PPPM | 220 W at 8/20 µs - handles lightning-induced surges in telecom and antenna feed lines. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 3-terminal, 2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm pitch, standard footprint for reflow/wave soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Low-impedance return path for negative transients; must be connected directly to system ground plane. |
| 2 | VCC | Positive rail connection for clamping positive transients; requires stable local supply decoupling. |
| 3 | I/O | Protected signal line input/output; connects to connector or IC pin requiring ESD hardening. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail bidirectional clamping | Enables protection of unidirectional or bidirectional signals without polarity constraints or external bias. |
| 0.6 pF typical capacitance | Minimizes signal distortion and timing skew on high-speed serial buses including I²C, USB, and audio DAC links. |
| ≤30 nA reverse leakage at 25 °C | Prevents measurable DC offset or battery drain in always-on sensor or RF front-end applications. |
| Clamping voltage ≤20 V at 11 A | Ensures safe operation for 3.3 V, 5 V, and 12 V logic families by limiting overshoot below absolute maximum ratings. |
Applications
| Telecom Interface Protection | I²C Bus Protection |
|---|---|
|
Use Scenario: Protecting Ethernet PHY MDI-X lines and DSL line drivers from ESD events during plugging/unplugging. IC Role / Device Role / Timing Role: ESD transient suppressor placed at board edge connector, clamping ±30 kV discharges before reaching PHY IC.

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 ESD9B5.0ST5G | Unidirectional, 5.0 V VBR, 0.8 pF capacitance, 12 A 8/20 µs surge rating. | Requires separate GND and VCC connections only for bidirectional clamping; unsuitable for rail-to-rail signal lines without external bias. | Select when protecting 5 V-only unidirectional lines where lower VBR improves clamping but higher capacitance is acceptable. |
| Vishay VEML6030X01 | Not applicable - optical ambient light sensor, not an ESD protection device. | - | Excluded: VEML6030X01 is unrelated functionally and electrically; not a valid alternative. |
Compared with ESD9B5.0ST5G, NUP1301,215 offers true rail-to-rail operation and 0.2 pF lower capacitance critical for >50 MHz signals, while avoiding the need for external bias networks required by unidirectional alternatives.

FAQ
What is the maximum continuous reverse voltage the NUP1301,215 can withstand?
The NUP1301,215 has a repetitive peak reverse voltage (VRRM) of 80 V, verified per IEC 60134 Absolute Maximum Ratings. This allows safe DC blocking and transient suppression on 24 V industrial control lines and 48 V telecom power feeds without breakdown or accelerated aging.
Can NUP1301,215 protect bidirectional data lines without external components?
Yes - its internal rail-to-rail diode configuration enables direct protection of bidirectional buses like I²C or USB D+/D− without pull-up resistors, bias voltages, or additional capacitors. Pins 1 (GND) and 2 (VCC) provide symmetrical clamping paths for both polarities of ESD stress on pin 3 (I/O).
How does the 0.6 pF capacitance impact high-frequency signal integrity?
At 0.6 pF typical, the NUP1301,215 introduces negligible impedance above 100 MHz (Zc ≈ 2.7 kΩ at 100 MHz), preserving rise times and eye diagrams on interfaces such as HDMI DDC, MIPI I3C, and audio DAC outputs. Measured insertion loss remains <0.1 dB up to 500 MHz.
Is NUP1301,215 qualified for automotive applications?
No - the 14 April 2023 datasheet explicitly states this part is non-automotive qualified. It lacks AEC-Q200 stress testing and automotive-grade process controls. For automotive use, Nexperia recommends the NUP1301-Q series variants, which undergo full qualification per AEC-Q200 Rev D.
