Product details
Overview
NUP4114UCLW1T1G 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 junction capacitance (I/O to GND), ±8 kV IEC 61000-4-2 contact ESD immunity, and clamps at 8.3 V @ 1 A peak pulse current - enabling robust signal integrity in compact portable electronics.
For engineers reviewing the NUP4114UCLW1T1G datasheet, pinout, applications, or equivalent options, key selection criteria include ultra-low capacitance for >480 Mbps USB 2.0 compliance, low clamping voltage under fast transients (<1 ns response), and SC-88 package compatibility with space-constrained PCB layouts.
Technical Context
The NUP4114UCLW1T1G integrates four unidirectional steering diodes and one bidirectional ESD clamp in a single SC-88 (Case 419B) package. Its internal topology routes transient currents from I/O pins (1, 3, 4, 6) to ground (Pin 2) or VCC (Pin 5), depending on configuration - supporting both supply-referenced and isolated protection schemes.
It operates across −40°C to +125°C junction temperature, sustains 12 A peak pulse current (8/20 µs), and achieves <1.0 ns response time due to optimized silicon geometry and low-parasitic packaging - critical for preserving edge fidelity in high-speed serial links.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Peak Reverse Voltage | 5.5 V - sets maximum steady-state signal swing before leakage rises significantly; matches USB 2.0 and HDMI DC bias levels. |
| Junction Capacitance (I/O–GND) | 0.6 pF typical - ensures minimal signal attenuation and phase distortion on 480 Mbps USB 2.0 differential pairs. |
| Clamping Voltage @ 1 A | 8.3 V - limits transient overvoltage seen by protected ICs during ESD events, staying below typical 10 V I/O absolute max ratings. |
| ESD Immunity (IEC 61000-4-2) | ±8 kV contact - exceeds Level 4 requirement, enabling drop-in use in consumer-grade USB/HDMI ports without additional staging. |
| Response Time | <1.0 ns - enables effective suppression of sub-nanosecond ESD rise times, preventing latch-up or gate oxide damage in sensitive receivers. |
| Operating Junction Temp | −40°C to +125°C - supports deployment in automotive infotainment displays and industrial USB peripherals with extended thermal envelopes. |
Pinout & Package
Package: SC-88 (Case 419B), 6-pin surface-mount, 2.00 mm × 1.25 mm × 0.90 mm body, 0.65 mm pitch, Pb-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | I/O Line 1 | Protected high-speed data input/output; connected to USB D+, HDMI TMDS+, or LVDS+ trace. |
| 2 | Ground (GND) | Low-inductance return path for ESD current; must connect directly to solid ground plane to minimize clamping voltage overshoot. |
| 3 | I/O Line 2 | Second protected data line; used for complementary signal (e.g., USB D−, HDMI TMDS−). |
| 4 | I/O Line 3 | Third protected line; supports multi-lane interfaces like dual-channel LVDS or auxiliary DDC lines. |
| 5 | VCC Reference | Optional positive rail connection; enables supply-referenced clamping (VC = VCC + VF) for lower capacitance and tighter voltage control. |
| 6 | I/O Line 4 | Fourth protected line; commonly assigned to USB ID, HDMI CEC, or panel power enable signals. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low I/O-to-GND capacitance | 0.6 pF typical - preserves signal integrity on 480 Mbps USB 2.0 and 1.65 Gbps HDMI 1.4 channels without equalization. |
| Low clamping voltage | 8.3 V @ 1 A - keeps transient stress below 10 V absolute maximum ratings of most USB PHYs and HDMI receivers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD4E001DQAR | 0.5 pF capacitance, 5.5 V VRWM, ±12 kV contact ESD rating - slightly lower capacitance but higher clamping voltage (12 V @ 1 A). | Better for ultra-high-speed (>1 Gbps) SerDes where capacitance dominates; less suitable for 3.3 V I/O with tight margin to 10 V abs max. | Choose TPD4E001DQAR when minimizing capacitive loading is primary; verify clamping headroom with downstream IC specs. |
| ESD5V3U2U | 0.8 pF capacitance, 5.0 V VRWM, ±8 kV contact rating - higher capacitance, lower working voltage, same package (SC-88). | Optimized for 5 V tolerant logic; less ideal for USB 2.0 where 5.5 V VRWM provides safety margin against VBUS ripple. | Prefer ESD5V3U2U only if system uses strict 5.0 V signaling and requires lower cost; NUP4114UCLW1T1G offers superior VRWM margin. |
Compared with TPD4E001DQAR and ESD5V3U2U, the NUP4114UCLW1T1G strikes a balanced trade-off: its 0.6 pF capacitance and 5.5 V VRWM support USB 2.0 timing margins, while 8.3 V clamping ensures compatibility with common 3.3 V/5 V interface ICs - making it the most broadly applicable choice for mixed-signal portable designs.

FAQ
What is the maximum operating temperature range for the NUP4114UCLW1T1G?
The NUP4114UCLW1T1G has an operating junction temperature range of −40°C to +125°C, validated per its datasheet maximum ratings table. This allows reliable deployment in automotive infotainment systems, industrial USB peripherals, and thermally demanding notebook environments where ambient temperatures exceed 85°C. The NUP4114UCLW1T1G maintains specified clamping performance and leakage current across this full range.
Does the NUP4114UCLW1T1G require external biasing to function correctly?
No, the NUP4114UCLW1T1G operates unidirectionally without external bias; its steering diodes conduct automatically when I/O voltage exceeds either ground or VCC by one forward voltage drop. Pin 5 (VCC) is optional - leaving it unconnected enables ground-referenced clamping (VC = VF + VESD), while connecting it to the supply rail lowers capacitance and tightens clamping. The NUP4114UCLW1T1G functions correctly in either configuration.
Can the NUP4114UCLW1T1G protect both data and power lines simultaneously?
Yes - the NUP4114UCLW1T1G protects up to four data lines (Pins 1, 3, 4, 6) and optionally the VCC rail (Pin 5) using its integrated ESD diode. When Pin 5 connects to the supply, transient energy on data lines is steered to VCC, and the internal ESD diode clamps overvoltage on the rail itself. This dual-role capability eliminates need for separate power-rail TVS devices in compact USB/HDMI port designs using the NUP4114UCLW1T1G.
Is the NUP4114UCLW1T1G compatible with automated SMT assembly processes?
Yes, the NUP4114UCLW1T1G is supplied in Pb-free SC-88 tape-and-reel packaging (3000 units per reel) and rated for lead solder temperature up to 260°C for 10 seconds - fully compliant with IPC/JEDEC J-STD-020 moisture sensitivity level (MSL) requirements for standard reflow profiles. Its 0.65 mm pitch and defined land pattern ensure reliable placement and solder joint formation in high-volume manufacturing using the NUP4114UCLW1T1G.
How does the NUP4114UCLW1T1G achieve <1.0 ns response time?
The NUP4114UCLW1T1G achieves sub-nanosecond response through optimized silicon junction design and low-parasitic SC-88 packaging - minimizing total device capacitance and series inductance. Its internal structure uses fast-switching steering diodes with low forward voltage and tightly controlled avalanche characteristics, enabling conduction onset within 0.8 ns of ESD voltage rise. This speed is verified via oscilloscope waveform analysis per IEC61000-4-2 testing in the NUP4114UCLW1T1G datasheet.
