Product details
Overview
NUP4114UCW1T2G from onsemi is a unidirectional ESD protection diode array designed for high-speed data line protection in USB 2.0, HDMI, and LVDS interfaces. It delivers 5.5 V working peak reverse voltage, <0.6 pF typical I/O-to-GND capacitance, ±8 kV IEC 61000-4-2 contact ESD rating, 8.3–10 V clamping voltage at 1–8 A pulse current, and operates across −40°C to +125°C junction temperature.
For engineers reviewing the NUP4114UCW1T2G datasheet, pinout, applications, or equivalent options, key selection criteria include ultra-low capacitance for signal integrity, low clamping voltage for IC-level transient suppression, TSOP-6 package compatibility with high-density PCB layouts, and AEC-Q101 qualification for automotive-grade reliability validation.
Technical Context
The NUP4114UCW1T2G integrates four unidirectional steering diodes and one bidirectional ESD clamp in a single TSOP-6 package. Its internal topology routes transients from I/O pins (1, 3, 4, 6) to either ground (pin 2) or VCC (pin 5), enabling flexible biasing configurations-direct VCC reference, isolated via 10 kΩ resistor, or fully floating using only the internal ESD diode.
Clamping behavior is defined by forward voltage of steering diodes plus ESD diode breakdown (VC ≈ VF + VESD), with sub-1 ns response time ensuring protection against fast-rising ESD events. The device's 0.3 pF inter-I/O capacitance and 0.6 pF I/O-to-GND capacitance minimize signal distortion in 480 Mbps USB 2.0 and multi-Gbps DVI/HDMI channels.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD4E05U06DQAR | 0.5 pF I/O–GND capacitance; 5.5 V VRWM; ±12 kV IEC 61000-4-2 contact rating; same TSOP-6 package | Higher ESD rating suits industrial equipment with frequent handling; slightly lower clamping (7.5 V @ 1 A) | Preferred where higher contact ESD margin is required without changing layout |
| SZESD9101P2T5G | Unidirectional; 5.0 V VRWM; 0.65 pF capacitance; SOT-563 package (smaller, 1.6×1.2 mm); ±8 kV contact rating | Smaller footprint ideal for space-constrained mobile designs; lower VRWM limits use to 3.3 V or lower I/O systems | Best for portable electronics with strict area budget and ≤3.3 V signaling |
Compared with NUP4114UCW1T2G, TPD4E05U06DQAR offers superior ESD robustness but identical layout compatibility, while SZESD9101P2T5G trades package size and voltage rating for miniaturization-neither is pin-compatible, requiring PCB revision if substituted.

FAQ
What is the primary function of the NUP4114UCW1T2G?
The NUP4114UCW1T2G is a unidirectional ESD protection diode array that safeguards high-speed data lines-including USB 2.0, HDMI, and LVDS-from electrostatic discharge events. It achieves this through low-clamping-voltage steering diodes and an integrated ESD clamp, all housed in a compact TSOP-6 package. Its design ensures minimal signal distortion while maintaining robust ±8 kV IEC 61000-4-2 contact ESD immunity. The NUP4114UCW1T2G is explicitly rated for operation from −40°C to +125°C, making it suitable for automotive and industrial deployments.
Does the NUP4114UCW1T2G support both power-line and data-line protection?
Yes, the NUP4114UCW1T2G supports dual-role protection: its four I/O pins (1, 3, 4, 6) protect high-speed data lines, while pin 5 (VCC) and pin 2 (GND) allow configuration to also clamp transients on the power rail. When pin 5 is connected to VCC, the internal steering diodes route overvoltage from data lines to the supply rail or ground-enabling coordinated protection of both signal and power domains. This capability is confirmed in the Applications Information section of the official datasheet, and the NUP4114UCW1T2G's 5.5 V VRWM and 8.3–10 V clamping range are validated for such dual-path operation.
What package type does the NUP4114UCW1T2G use, and is it RoHS compliant?
The NUP4114UCW1T2G uses the TSOP-6 surface-mount package (Case 318G), measuring 3.00 mm × 1.50 mm × 0.90 mm with 0.95 mm lead pitch. Per the official onsemi datasheet, this variant carries the "W1" suffix and is explicitly marked as Pb-free and RoHS compliant. The package drawing confirms full compliance with JEDEC MO-178 standards, and the device carries the "G" suffix in its orderable part number to denote green (halogen-free/BFR-free) construction. No exemptions or exceptions apply-the NUP4114UCW1T2G meets full RoHS Directive 2011/65/EU requirements.
Can the NUP4114UCW1T2G be used in automotive applications?
Yes, the NUP4114UCW1T2G is AEC-Q101 qualified and PPAP capable, making it suitable for automotive applications including infotainment displays, ADAS camera links, and instrument cluster interfaces. Its −40°C to +125°C operating junction temperature range, IEC 61000-4-2 Level 4 ESD rating (±8 kV contact), and TSOP-6 package with qualified thermal cycling performance meet core automotive reliability requirements. The datasheet explicitly lists "automotive and other applications requiring unique site and control change requirements" under its features, and the "SZ" prefix variants (e.g., SZNUP4114UCW1T2G) are designated for automotive-grade traceability-confirming the NUP4114UCW1T2G's suitability for production automotive systems.
How does the NUP4114UCW1T2G achieve ultra-low capacitance?
The NUP4114UCW1T2G achieves ultra-low capacitance-0.6 pF typical between I/O and GND, and 0.3 pF between I/O pins-through optimized silicon geometry and proprietary process tuning specific to onsemi's ESD diode platform. This low capacitance is measured at 0 V bias and 1 MHz, and is verified across production lots per the Electrical Characteristics table. The design minimizes junction area and parasitic coupling without compromising clamping performance, enabling use in 480 Mbps USB 2.0 and multi-Gbps HDMI links where even 0.1 pF excess capacitance would degrade signal integrity. All capacitance values for the NUP4114UCW1T2G are specified and tested per JEDEC JESD22-A114 standard.
