Product details
Overview
SZNUP4114HMR6T1G 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 features 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 V clamping voltage at 1 A, and operates across −40°C to +125°C junction temperature range.
For engineers reviewing the SZNUP4114HMR6T1G datasheet, pinout, applications, or equivalent options, key selection criteria include ultra-low capacitance for signal integrity, automotive-grade AEC-Q101 qualification, TSOP-6 package layout compatibility, and verified clamping performance under IEC 61000-4-2 Level 4 ESD stress.
Technical Context
The SZNUP4114HMR6T1G integrates four low-capacitance steering diodes and one bidirectional ESD protection diode in a single TSOP-6 package. Its internal configuration supports three reference modes: VCC-referenced (pin 5 tied to supply), resistor-isolated VCC (10 kΩ), or floating-reference using the internal ESD diode (pin 5 open).
During transient events, the device routes ESD current via low-inductance paths - either to ground (pin 2) or to VCC (pin 5) - achieving clamping voltages as low as 8.3 V at 1 A. The 1 ns typical response time and sub-0.6 pF I/O-to-GND capacitance preserve signal fidelity on 480 Mbps USB 2.0 and multi-Gbps video interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Peak Reverse Voltage | 5.5 V - Sets maximum steady-state DC bias before leakage increases significantly. |
| Clamping Voltage @ 1 A | 8.3 V typical - Limits voltage seen by protected IC during fast ESD transients. |
| Junction Capacitance (I/O to GND) | 0.6 pF typical - Enables use on USB 2.0 and HDMI data lines without signal degradation. |
| IEC 61000-4-2 Contact ESD | ±8 kV - Meets Level 4 immunity requirement for handheld and portable electronics. |
| Operating Junction Temp | −40°C to +125°C - Supports automotive cabin and industrial ambient environments. |
| Response Time | <1.0 ns typical - Ensures protection activation before sensitive circuitry sustains damage. |
| Breakdown Voltage @ 1 mA | 5.5–6.5 V - Defines sharp turn-on threshold for reliable overvoltage detection. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD5V3U2U-2/TR | 0.5 pF capacitance, 5.3 V working voltage, ±12 kV air discharge, SOT-23-3 package (3-pin, single-channel). | Single-line protection only; requires four units for quad-line coverage; lacks integrated VCC reference pin. | Choose for cost-sensitive, space-tolerant designs where discrete placement and higher air ESD rating are prioritized over integration. |
| TPD4E001DRYR | 0.5 pF capacitance, 5.5 V working voltage, ±8 kV contact, 6-pin SON package, same quad-channel topology. | Non-automotive grade (no AEC-Q101); slightly higher 9.5 V clamping at 1 A; identical pinout but different marking and thermal pad design. | Choose for non-automotive industrial or computing applications requiring drop-in layout reuse and TI ecosystem support. |
Compared with SZNUP4114HMR6T1G, ES5V3U2U-2/TR offers superior air ESD rating but requires four placements and lacks VCC referencing, while TPD4E001DRYR matches pin count and capacitance but omits automotive qualification and delivers higher clamping voltage - making SZNUP4114HMR6T1G optimal for space-constrained, AEC-Q101-compliant high-speed data protection.

FAQ
What is the primary function of the SZNUP4114HMR6T1G?
The SZNUP4114HMR6T1G is a unidirectional ESD protection diode array that safeguards up to four high-speed data lines from electrostatic discharge events. It achieves this through low-capacitance steering diodes and an integrated ESD clamp, delivering 8.3 V clamping at 1 A while maintaining 0.6 pF I/O-to-GND capacitance. Its TSOP-6 package and AEC-Q101 qualification make it ideal for automotive and portable USB/HDMI interfaces.
Does the SZNUP4114HMR6T1G support VCC-referenced clamping?
Yes, the SZNUP4114HMR6T1G supports VCC-referenced clamping via pin 5. When connected to a stable 3.3 V or 5 V supply rail, the internal steering diodes route positive transients to VCC and negative transients to ground (pin 2), lowering effective clamping voltage compared to ground-only operation. This configuration is explicitly validated in the datasheet's Application Information section and improves protection margin for powered interfaces.
What is the maximum operating temperature range for the SZNUP4114HMR6T1G?
The SZNUP4114HMR6T1G has a specified operating junction temperature range of −40°C to +125°C. This range is confirmed in the Maximum Ratings table of the official datasheet (Rev. 8, December 2021) and aligns with its AEC-Q101 qualification, enabling deployment in under-hood automotive modules, industrial control panels, and outdoor-connected devices without derating.
Can the SZNUP4114HMR6T1G be used for HDMI TMDS line protection?
Yes, the SZNUP4114HMR6T1G is explicitly recommended for HDMI and DVI applications in its Typical Applications list and Applications Information section. Its 0.6 pF I/O-to-GND capacitance ensures minimal distortion of 165 MHz TMDS signals, and its ±8 kV IEC 61000-4-2 contact rating meets HDMI compliance requirements for hot-plug and user-handling ESD events. Layout guidelines emphasize short traces to pin 2 (GND) and optional VCC tie to pin 5 for optimal performance.
Is the SZNUP4114HMR6T1G pin-compatible with other NUP4114 variants?
No - the SZNUP4114HMR6T1G uses the TSOP-6 package (Case 318G), while other variants like NUP4114UCLW1T1G use SC-88 (Case 419B) and NUP4114UPXV6T1G use SOT-563 (Case 463A). These packages have different pin counts, footprints, and pin assignments. The TSOP-6 variant has six pins with defined I/O, GND, and VCC roles; SC-88 and SOT-563 versions differ in both mechanical layout and internal connectivity, so they are not interchangeable without PCB redesign.
