Product details
Overview
NSPM0051MUT5G from onsemi is a unidirectional ESD protection diode in UDFN2 package, rated for ±30 kV IEC 61000−4−2 contact discharge, 70 A IEC 61000−4−5 lightning surge, 5.0 V working reverse voltage, and 11.5 V clamping voltage at 70 A. It protects high-speed USB 2.0, HDMI, and audio data lines in portable electronics.
For engineers reviewing the NSPM0051MUT5G datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage at 70 A (11.5 V), junction capacitance (16 pF), dynamic resistance (0.04 Ω), and UDFN2 footprint compatibility with space-constrained PCB layouts.
Technical Context
This device operates as a single-channel, cathode-to-anode unidirectional TVS diode. Its low 16 pF junction capacitance and 0.04 Ω dynamic resistance enable minimal signal distortion on 480 Mbps USB 2.0 differential pairs while maintaining sub-12 V clamping under full 70 A IEC 61000−4−5 stress.
The UDFN2 package (1.6 mm × 1.0 mm, 0.4 mm height) places anode (Pin 2) and cathode (Pin 1) on opposite ends of the die edge, supporting direct series placement in signal paths. Thermal performance is specified across −65 °C to +150 °C junction temperature range, enabling use in automotive infotainment and industrial HMI front panels.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Reverse Voltage | 5.0 V - Maximum continuous DC voltage before leakage exceeds 0.1 µA; sets upper limit for protected signal rail voltage. |
| Clamping Voltage @ 70 A | 11.5 V - Peak voltage seen by downstream IC during full 70 A 8/20 µs surge; ensures safe margin below typical 13.2 V USB PHY abs max. |
| Junction Capacitance | 16 pF - Measured at 0 V, 1 MHz; enables <0.5 dB insertion loss on 480 Mbps USB 2.0 signals with proper layout. |
| Dynamic Resistance | 0.04 Ω - Low impedance during transient conduction; reduces voltage overshoot and improves energy handling linearity. |
| ESD Rating | ±30 kV contact per IEC 61000−4−2 Level 4 - Validated protection level for handheld device touch surfaces and exposed ports. |
| Package | UDFN2 (Case 517CZ), 1.6 mm × 1.0 mm - Enables placement directly at connector entry point without routing detours. |
Pinout & Package
NSPM0051MUT5G uses a 2-terminal UDFN2 package (Case 517CZ) with exposed pad not electrically connected. Pin 1 is cathode; Pin 2 is anode. The compact 1.6 mm × 1.0 mm outline supports high-density routing adjacent to USB/HDMI connectors.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode | Connected to protected signal line; conducts surge current toward ground when voltage exceeds VRWM + VBR. |
| Pin 2 | Anode | Connected to system ground; completes low-inductance return path for ESD current during clamping event. |
Key Features
| Feature | Design Value |
|---|---|
| IEC 61000−4−2 Level 4 ESD protection | ±30 kV contact discharge capability ensures robustness against user-handling ESD in consumer handhelds. |
| Low 16 pF junction capacitance | Preserves signal integrity on 480 Mbps USB 2.0 and 1.65 Gbps HDMI 1.4a data lanes without equalization. |
| 0.04 Ω dynamic resistance | Minimizes voltage overshoot during fast-rising ESD transients, improving clamping consistency across pulse amplitudes. |
| UDFN2 footprint (1.6 × 1.0 mm) | Enables placement within 2 mm of USB micro-B or HDMI Type A connector pads, reducing loop inductance. |

Use Value: −65 °C to +150 °C operating range meets AEC-Q200 Grade 2 requirements for under-dash mounting locations. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD1E05U06DPYR | Lower 5.5 V clamping at 1 A; higher 22 pF capacitance; same UDFN2-2 package. | Better for lower-voltage 3.3 V I/O; less suitable for 480 Mbps USB due to higher capacitance. | Select when clamping voltage priority outweighs bandwidth; verify 22 pF impact on eye diagram. |
| SMAJ5.0A | DO-214AC package; 9.2 V clamping at 70 A; 200 pF capacitance; higher leakage (1 µA). | Only viable for low-speed DC power/signal lines; incompatible with high-speed data interfaces. | Use only for non-high-speed applications where board space allows larger SMC footprint. |
Compared with TPD1E05U06DPYR and SMAJ5.0A, NSPM0051MUT5G delivers optimal balance of low clamping (11.5 V @ 70 A), ultra-low capacitance (16 pF), and miniature UDFN2 packaging-making it uniquely suited for USB 2.0 and HDMI interface protection where signal fidelity and board area are critical.

FAQ
What is the maximum clamping voltage of NSPM0051MUT5G under full IEC 61000−4−5 stress?
The NSPM0051MUT5G exhibits a maximum clamping voltage of 11.5 V when subjected to a 70 A, 8/20 µs IEC 61000−4−5 lightning surge waveform at 25 °C ambient. This value is measured across the device terminals and represents the peak voltage seen by downstream circuitry during worst-case surge conditions, ensuring compatibility with 13.2 V absolute maximum ratings of common USB PHYs.
Does NSPM0051MUT5G support bidirectional signal lines like USB D+ and D−?
NSPM0051MUT5G is a unidirectional ESD protection diode, meaning it conducts only when the cathode is positive relative to the anode. For true bidirectional protection of differential USB 2.0 lines, two NSPM0051MUT5G devices must be used-one per line-with cathodes tied to the signal and anodes grounded. It does not replace a dedicated bidirectional TVS array.
What is the junction capacitance of NSPM0051MUT5G and how does it affect USB 2.0 performance?
The NSPM0051MUT5G has a junction capacitance of 16 pF measured at 0 V and 1 MHz. At USB 2.0's 480 Mbps data rate (240 MHz fundamental), this adds negligible insertion loss (<0.5 dB) when placed with short traces, preserving eye diagram integrity without requiring receiver equalization-unlike higher-capacitance alternatives exceeding 20 pF.
Is NSPM0051MUT5G compliant with automotive reliability standards?
NSPM0051MUT5G operates across −65 °C to +150 °C junction temperature and is RoHS-compliant, Pb-free, and halogen-free. While not AEC-Q200 certified as a standalone component, its thermal and electrical specs meet Grade 2 requirements for under-hood infotainment interfaces; system-level qualification is required for automotive deployment.
How is the UDFN2 package of NSPM0051MUT5G mounted and what soldering profile is recommended?
The NSPM0051MUT5G UDFN2 package (Case 517CZ) uses standard reflow soldering with a peak temperature of 260 °C for ≤30 seconds. Its 1.6 mm × 1.0 mm body and 0.4 mm height require stencil aperture matching per onsemi's SOLDERINGRM/D manual; no thermal pad connection is needed as the exposed copper is non-functional.
