Product details
Overview
NUP4114UCLW1T2G 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, 8.3–10 V clamping voltage at 1–8 A pulse current, and operates across −40°C to +125°C.
For engineers reviewing the NUP4114UCLW1T2G 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 layouts, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
The NUP4114UCLW1T2G integrates four steering diodes and one bidirectional ESD clamp in a single TSOP-6 package, enabling protection of four independent I/O lines referenced to either ground or VCC. Its architecture supports three configuration modes: VCC-referenced, resistor-isolated, or fully isolated using the internal ESD diode as reference.
Clamping behavior is defined by forward voltage of steering diodes plus ESD diode voltage drop (VC = VF + VESD), with sub-1 ns response time and minimal parasitic inductance dependence due to optimized internal layout. The device meets IEC 61000-4-2 Level 4 (±8 kV contact / ±15 kV air) and ISO 10605 (±10–±30 kV) standards.

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, ±12 kV contact ESD rating, SOT-23-6 package (larger footprint than TSOP-6) | Higher ESD rating but higher package height (1.45 mm vs. 0.90 mm) limits use in ultra-thin devices | Preferred when ±12 kV system-level ESD margin is required and board height permits larger package |
| ESD5451N | 0.35 pF capacitance, 5.0 V VRWM, SC-70-6 package, no VCC pin (ground-referenced only) | Lacks VCC-referencing capability; unsuitable for configurations requiring bias-controlled clamping | Selected for lowest possible capacitance in space-constrained USB 3.0 Gen1 designs where VCC referencing is unnecessary |
Compared with TPD4E001DQAR and ESD5451N, the NUP4114UCLW1T2G uniquely balances ultra-low capacitance (0.6 pF), VCC/GND dual-reference flexibility, and automotive-grade qualification in the smallest profile TSOP-6 package-making it optimal for high-reliability, high-speed interface protection where board height and thermal robustness are critical.

FAQ
What is the primary function of the NUP4114UCLW1T2G?
The NUP4114UCLW1T2G is a unidirectional ESD protection diode array that safeguards four high-speed data lines from electrostatic discharge events. It uses integrated steering diodes and an ESD clamp to divert transient currents to ground or VCC, limiting clamping voltage to 8.3–10 V while maintaining ultra-low 0.6 pF capacitance. This ensures signal integrity on USB 2.0, HDMI, and LVDS interfaces without degrading timing margins. The NUP4114UCLW1T2G is especially suited for applications demanding AEC-Q101 qualification and compact TSOP-6 packaging.
How does the NUP4114UCLW1T2G differ from generic TVS diodes?
Unlike standard TVS diodes, the NUP4114UCLW1T2G features four independent I/O terminals (Pins 1,3,4,6) with dedicated ground (Pin 2) and optional VCC reference (Pin 5), enabling configurable clamping topologies. Its 0.6 pF I/O-to-GND capacitance is substantially lower than most TVS devices (>10 pF), making it viable for >480 Mbps data rates. The NUP4114UCLW1T2G also provides guaranteed ±8 kV IEC 61000-4-2 contact immunity and AEC-Q101 qualification-attributes rarely found together in general-purpose TVS components.
Can the NUP4114UCLW1T2G be used for power line protection?
Yes-the NUP4114UCLW1T2G protects both data and power lines via its Pin 5 (VCC) connection. When Pin 5 is tied to the supply rail, the internal ESD diode clamps overvoltage transients on the power line to VCC + VF, preventing damage to regulators and downstream ICs. This dual-role capability eliminates the need for separate power-rail TVS devices in space-constrained designs. The NUP4114UCLW1T2G's 5.5 V VRWM and 12 A peak pulse current rating further support robust power-line transient suppression in USB and HDMI applications.
What is the significance of the "W1" suffix in NUP4114UCLW1T2G?
"W1" denotes the TSOP-6 package variant (Case 318G) with Pb-free finish and tape-and-reel packaging (3000 units per reel). This suffix distinguishes it from other NUP4114 variants like "UCL" (SC-88) or "PXV6" (SOT-563). The W1 package measures 3.00 mm × 1.50 mm × 0.90 mm with 0.95 mm lead pitch, optimized for fine-pitch automated assembly and thermal performance in high-density layouts. The NUP4114UCLW1T2G's W1 marking ensures mechanical and electrical compatibility with existing TSOP-6 footprints and reflow profiles.
Does the NUP4114UCLW1T2G require external biasing components?
No external biasing is required for basic ground-referenced operation: Pins 1,3,4,6 connect to protected lines, Pin 2 to ground, and Pin 5 left open. However, connecting Pin 5 to VCC lowers effective capacitance and improves clamping symmetry-no resistor needed. For isolation, a 10 kΩ resistor between Pin 5 and VCC is recommended per the datasheet. These configuration options are intrinsic to the NUP4114UCLW1T2G's architecture and do not rely on external passive components for core ESD functionality.
