Product details
Overview
NSPM0061MUT5G from onsemi is a unidirectional ESD protection diode in UDFN2 (1.6 mm × 1.0 mm) package, rated for ±30 kV IEC 61000−4−2 contact discharge, 70 A IEC 61000−4−5 lightning surge, and 6.3 V working reverse voltage - deployed to safeguard high-speed USB 2.0, HDMI, and audio data lines against electrostatic damage.
For engineers reviewing the NSPM0061MUT5G datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage at 70 A (11.5 V), junction capacitance (12 pF @ 0 V), dynamic resistance (0.04 Ω), operating temperature range (−65 °C to +150 °C), and unidirectional polarity configuration.
Technical Context
This device operates as a single-channel, cathode-to-anode unidirectional TVS diode optimized for low-capacitance signal line protection. Its TLP-characterized turn-on behavior ensures rapid response (<1 ns) to ESD transients while maintaining sub-12 pF capacitance to preserve signal integrity on 480 Mbps USB 2.0 and 1.65 Gbps HDMI interfaces.
The NSPM0061MUT5G uses silicon avalanche structure with controlled breakdown at 6.5–9.0 V (VBR, IT = 1 mA), delivering stable clamping from 7.5 V (at 1 A) up to 11.5 V (at 70 A), and exhibits 0.04 Ω dynamic resistance per TLP measurement - enabling robust voltage limiting without signal distortion under multi-amp surge conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Reverse Voltage | 6.3 V - maximum continuous DC or peak AC voltage the diode blocks without leakage degradation |
| Breakdown Voltage | 6.5–9.0 V @ 1 mA - defines reliable conduction onset during transient overvoltage events |
| Clamping Voltage | 11.5 V @ 70 A, 8/20 µs - peak voltage seen by protected IC during worst-case lightning surge |
| Junction Capacitance | 12 pF @ 0 V, 1 MHz - low enough to avoid signal attenuation or rise-time degradation on USB 2.0 lines |
| Dynamic Resistance | 0.04 Ω - ensures minimal voltage overshoot and tight clamping control across current range |
| ESD Rating | ±30 kV contact per IEC 61000−4−2 Level 4 - exceeds industrial and consumer immunity requirements |
| Operating Temperature | −65 °C to +150 °C - supports automotive under-hood and industrial extended-range deployments |
Pinout & Package
NSPM0061MUT5G is housed in a 2-terminal UDFN2 package (Case 517CZ), measuring 1.6 mm × 1.0 mm × 0.55 mm, with side-wettable flanks for automated optical inspection. The package is Pb-free, halogen-free, and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode | Connected to system ground or low-impedance return path; conducts transient current into ground during ESD event |
| Pin 2 | Anode | Connected to protected signal line (e.g., USB D+, HDMI TMDS+); reverse-biased during normal operation |
Key Features
| Feature | Design Value |
|---|---|
| IEC 61000−4−2 Level 4 ESD protection | ±30 kV contact discharge - eliminates need for secondary board-level shielding in handheld and portable designs |
| Low dynamic resistance | 0.04 Ω - minimizes clamping voltage overshoot and improves energy handling consistency across pulse amplitudes |
| Ultra-low junction capacitance | 12 pF - preserves signal edge rate and eye diagram integrity on 480 Mbps USB 2.0 and 720p HDMI links |
| High surge current rating | 70 A @ 8/20 µs - withstands multiple IEC 61000−4−5 lightning surges without parametric shift or failure |
| Extended temperature operation | −65 °C to +150 °C - qualified for under-dash automotive infotainment and industrial motor drive I/O protection |
Applications
| USB 2.0 Interface Protection | HDMI Signal Line Protection |
|---|---|
Use Scenario: Protecting D+ and D− lines of USB 2.0 ports in smartphones, tablets, and docking stations against user-hand ESD events. IC Role / Device Role / Timing Role: Unidirectional transient voltage suppressor placed in series between connector and PHY IC input pins. Use Value: 12 pF capacitance avoids signal rise-time degradation; 11.5 V clamping at 70 A prevents PHY latch-up or oxide damage during surge events. | Use Scenario: Safeguarding TMDS+ and TMDS− differential pairs in HDMI 1.4 receivers and transmitters against hot-plug and cable-discharge ESD. IC Role / Device Role / Timing Role: Low-capacitance shunt protector mounted directly at HDMI connector, referenced to local ground plane.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD2E001DRYR | Bi-directional configuration; 10 pF capacitance; 3.6 V VRWM; lower clamping (6.5 V @ 1 A) | Better suited for bidirectional data lines like I²C or low-voltage GPIO where polarity reversal occurs | Select when protecting symmetric, low-voltage busses requiring equal positive/negative clamping |
| SMAJ6.0A | DO-214AC package; 600 W peak power; 100 pF capacitance; 6.0 V VRWM; higher leakage (5 µA) | Targeted at power rail or low-frequency analog line protection, not high-speed digital interfaces | Choose only for non-signal-line applications where capacitance and speed are non-critical |
Compared with TPD2E001DRYR and SMAJ6.0A, the NSPM0061MUT5G delivers optimal trade-off for high-speed unidirectional signal lines: lowest capacitance among unidirectional UDFN options, precise 6.3 V working voltage alignment with 3.3 V I/O rails, and industry-leading 0.04 Ω dynamic resistance for consistent clamping performance across surge amplitudes.

FAQ
What is the polarity configuration of the NSPM0061MUT5G?
The NSPM0061MUT5G is a unidirectional ESD protection diode, with Pin 1 as cathode and Pin 2 as anode. It conducts only when the anode voltage exceeds the cathode voltage by the breakdown threshold (6.5–9.0 V), making it suitable for protecting signal lines referenced to ground - such as USB D+ or HDMI TMDS+ - where polarity is fixed and reverse conduction must be blocked during normal operation. This configuration ensures no DC leakage path is created across the protected line.
Does the NSPM0061MUT5G meet automotive qualification standards?
The NSPM0061MUT5G is not AEC-Q200 qualified as a standalone passive component, but it is AEC-Q101 stress-tested and widely used in automotive infotainment systems due to its −65 °C to +150 °C operating range, 70 A IEC 61000−4−5 surge capability, and robust package construction. For full automotive qualification, system-level validation per ISO 10605 and vehicle-specific EMC testing is required - the NSPM0061MUT5G provides the foundational ESD suppression layer in such validated designs.
What is the clamping voltage of the NSPM0061MUT5G at 35 A?
The NSPM0061MUT5G has a specified clamping voltage of 9.5 V at 35 A (8/20 µs pulse), per its Electrical Characteristics table. This value reflects the maximum voltage developed across the device terminals during a mid-amplitude surge event and is critical for ensuring downstream ICs remain within their absolute maximum input voltage ratings - especially for 3.3 V logic interfaces where margin above VCC is limited.
Can the NSPM0061MUT5G be used for bidirectional signal lines like I²C?
No - the NSPM0061MUT5G is unidirectional and will not protect against negative transients on bidirectional lines. For I²C, SMBus, or other bidirectional buses, a bi-directional ESD diode such as the TPD2E001DRYR is required. Using NSPM0061MUT5G on such lines would leave the line vulnerable to ESD events occurring when the signal swings below ground, as the device remains non-conductive in that direction.
What is the thermal resistance (RθJA) of the NSPM0061MUT5G in standard PCB layout?
The NSPM0061MUT5G does not specify RθJA in its datasheet because it is not intended for continuous power dissipation; it operates only during transient events lasting nanoseconds to microseconds. Its thermal design relies on short-pulse energy absorption rather than steady-state heat sinking. Therefore, RθJA is not characterized or guaranteed - thermal performance is validated via TLP and IEC 61000−4−2/−5 testing, confirming no degradation after repeated 70 A surges.
