Product details
Overview
SNUP2114UCMR6T1G from onsemi is a unidirectional ESD protection diode designed for high-speed data line protection in USB 2.0, HDMI, and DVI interfaces. It delivers 0.8 pF typical junction capacitance, 5.0 V working peak reverse voltage, and clamps to 9.0 V at 5 A peak pulse current - enabling signal integrity preservation in <480 Mbps data paths.
For engineers reviewing the SNUP2114UCMR6T1G datasheet, pinout, applications, or equivalent options, key selection criteria include IEC 61000-4-2 Level 4 compliance (±15 kV air/±13 kV contact), AEC-Q101 qualification, and TSOP-6 package compatibility with high-density PCB layouts.
Technical Context
The SNUP2114UCMR6T1G implements a single-channel unidirectional TVS structure optimized for low-capacitance transient suppression. Its clamping behavior is characterized under IEC 61000-4-2 waveforms and 8×20 μs surges, with breakdown voltage specified at 5.5–7.5 V (IT = 1 mA) and leakage limited to 1.0 μA at 5 V.
This device operates across −40 °C to +125 °C junction temperature and supports Pb-free reflow up to 260 °C (10 s). Its TSOP-6 footprint enables dual I/O line protection per package with dedicated VP (anode), VN (cathode), and NC terminals - distinct from bidirectional or multi-channel variants in the NUP2114 family.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Peak Reverse Voltage | 5.0 V - sets maximum continuous DC bias before conduction; matches USB 2.0 VBUS and DVI/HDMI signal swing limits. |
| Junction Capacitance | 0.8 pF @ VR = 0 V, 1 MHz - ensures minimal signal distortion on 480 Mbps USB 2.0 differential pairs. |
| Clamping Voltage | 9.0 V @ IPP = 5 A - limits transient overvoltage to safe levels for downstream PHY ICs during ESD events. |
| ESD Rating | ±15 kV air / ±13 kV contact per IEC 61000-4-2 Level 4 - exceeds industrial and automotive system-level immunity requirements. |
| Breakdown Voltage | 5.5–7.5 V @ IT = 1 mA - guarantees reliable turn-on margin above 5 V operating rails without false triggering. |
| Leakage Current | ≤1.0 μA @ VRWM = 5 V - prevents measurable power loss or signal degradation in always-on high-speed links. |
Pinout & Package
SNUP2114UCMR6T1G uses the TSOP-6 (Case 318G) package: 3.00 × 1.50 × 0.90 mm body, 0.95 mm pitch, Pb-free, RoHS-compliant. Pin 1 is marked with microdot or "P2M" top-side marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | I/O (Anode) | Input/output terminal connected to protected data line; conducts surge current toward ground when VP exceeds VN by >VBR. |
| 2 | VN (Cathode) | Ground reference node; ties to system GND plane to complete ESD current path with minimal inductance. |
| 3 | NC | No internal connection; must be left floating or tied to GND per layout guidelines - no electrical function. |
| 4 | I/O (Anode) | Second independent I/O terminal; enables dual-line protection (e.g., D+ and D−) within one TSOP-6 package. |
| 5 | VP (Anode) | Primary anode node shared with Pin 1; confirms unidirectional topology - only protects against positive transients on I/O lines. |
| 6 | NC | No internal connection; electrically isolated - avoids unintended coupling or parasitic paths in routing. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low capacitance | 0.8 pF typical - preserves signal rise/fall times and eye diagram integrity in USB 2.0 and DVI channels. |
| AEC-Q101 qualified | Validated for automotive applications including infotainment and ADAS display interfaces requiring PPAP support. |
| IEC 61000-4-2 Level 4 compliant | Withstands ±15 kV air and ±13 kV contact discharge - meets end-equipment certification requirements without external filtering. |
| Low clamping voltage | 9.0 V @ 5 A - reduces stress on 3.3 V or 5 V interface ICs during ESD events, improving system-level robustness. |
| Pb-free and RoHS-compliant | Meets global environmental regulations and supports lead-free reflow profiles up to 260 °C. |
Applications
| USB 2.0 Interface Protection | HDMI/DVI Data Line Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD5Z5.0T1G | Same SOT-553 package; 0.6 pF capacitance but lower 5.0 V standoff and 12 V clamping at 1 A. | Optimized for ultra-low-capacitance USB 3.0 applications; less robust clamping for high-energy USB 2.0 surges. | Select when minimizing capacitance is critical and peak surge current remains below 3 A. |
| TPD2EUSB30DRYR | 0.5 pF, dual-channel, 5.5 V standoff, but requires 0.65 mm pitch DRY package and higher layout complexity. | Targeted at USB 3.0 SuperSpeed lanes; not rated to AEC-Q101 and lacks IEC 61000-4-2 Level 4 validation. | Choose for next-gen interfaces needing sub-0.6 pF performance, accepting non-automotive qualification. |
Compared with ESD5Z5.0T1G and TPD2EUSB30DRYR, SNUP2114UCMR6T1G provides the optimal balance of IEC Level 4 compliance, AEC-Q101 qualification, and 0.8 pF capacitance in a manufacturable TSOP-6 package - making it the preferred choice for cost-sensitive, high-volume USB 2.0 and HDMI designs requiring automotive traceability.

FAQ
What is the primary function of the SNUP2114UCMR6T1G?
The SNUP2114UCMR6T1G is a unidirectional ESD protection diode designed to safeguard high-speed data lines from electrostatic discharge events. It operates by clamping transient voltages to safe levels - such as 9.0 V at 5 A - while maintaining ultra-low 0.8 pF junction capacitance to preserve signal integrity. Its role is strictly protective, not signal conditioning or voltage regulation.
Does the SNUP2114UCMR6T1G support bidirectional ESD protection?
No, the SNUP2114UCMR6T1G is explicitly unidirectional, as confirmed by its electrical characteristics table and pin configuration (VP/VN polarity). It protects only against positive transients on I/O lines relative to ground. For bidirectional protection, onsemi offers the NUP4201MR6T1G or NUP4105MR6T1G - neither of which share pinout or electrical equivalence with SNUP2114UCMR6T1G.
Is the SNUP2114UCMR6T1G qualified for automotive use?
Yes, the SNUP2114UCMR6T1G carries the "S" prefix designation and is AEC-Q101 qualified, with PPAP capability documented in the datasheet. It is rated for operation from −40 °C to +125 °C junction temperature and validated for automotive infotainment and display applications where ESD immunity and long-term reliability are required.
What does the "UCMR6T1G" suffix indicate in SNUP2114UCMR6T1G?
The "UCMR6T1G" suffix identifies the TSOP-6 package (CM), tape-and-reel packaging (R6), 3,000-unit reel quantity (T1), and Pb-free/RoHS compliance (G). This distinguishes it from the SOT-553 variant NUP2114UPXV5T1G and confirms mechanical compatibility with automated pick-and-place systems using standard TSOP-6 feeders.
Can the SNUP2114UCMR6T1G be used for USB 3.0 or higher-speed interfaces?
No - the SNUP2114UCMR6T1G is characterized and validated for USB 2.0 (480 Mbps) and HDMI 1.4 (up to 3.4 Gbps) applications. Its 0.8 pF capacitance and clamping response are not optimized for USB 3.0 SuperSpeed (5 Gbps) or PCIe Gen3+ signaling, where sub-0.5 pF devices like TPD2EUSB30DRYR are recommended instead.
