Product details
Overview
NSPM0101MUT5G from onsemi is a unidirectional ESD protection diode in UDFN2 package, rated for ±30 kV IEC 61000−4−2 contact discharge, 60 A IEC 61000−4−5 lightning surge, and 10 V working reverse voltage, deployed to safeguard USB 2.0 data lines against electrostatic discharge events.
For engineers reviewing the NSPM0101MUT5G datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage at 10 A (15 V) and 60 A (20 V), dynamic resistance (0.05 Ω), junction capacitance (400 pF), and UDFN2 footprint compatibility with high-speed signal integrity requirements.
Technical Context
This device operates as a single-channel, cathode-grounded unidirectional TVS diode, designed for low-capacitance transient suppression on I/O lines. Its clamping behavior is characterized by a 12 V breakdown voltage at 1 mA and a 20 V clamping voltage under 60 A 8/20 µs surge current.
The UDFN2 package enables direct placement adjacent to connectors without trace inductance penalty, while its 400 pF capacitance and 0.05 Ω dynamic resistance support signal integrity preservation for ≤480 Mbps USB 2.0 interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Reverse Voltage | 10 V - Maximum continuous DC voltage applied across anode-to-cathode without leakage exceeding 0.5 µA |
| Breakdown Voltage | 12 V @ 1 mA - Voltage at which device transitions from high-impedance to conduction, defining ESD trigger threshold |
| Clamping Voltage | 20 V @ 60 A - Peak voltage seen by protected IC during full IEC 61000−4−5 lightning surge event |
| Junction Capacitance | 400 pF @ 0 V, 1 MHz - Measured capacitance that directly impacts signal rise time and insertion loss on high-speed lines |
| Dynamic Resistance | 0.05 Ω - Low incremental resistance during transient conduction, minimizing voltage overshoot beyond clamping level |
| ESD Rating | ±30 kV contact per IEC 61000−4−2 Level 4 - Confirmed immunity to worst-case human-body-model ESD events |
Pinout & Package
NSPM0101MUT5G uses the UDFN2 (Case 517CZ) package: 1.6 mm × 1.0 mm, 0.5 mm pitch, 2-terminal surface-mount outline with exposed pad not connected internally. The package supports reflow soldering per J-STD-020 and is Pb-free, halogen-free, and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Ground reference terminal | Connected to system ground plane; serves as return path for ESD current and defines unidirectional conduction direction |
| 2 (Anode) | Protected line terminal | Connected to vulnerable I/O trace (e.g., USB D+); conducts transient current to ground when voltage exceeds VRWM |
Key Features
| Feature | Design Value |
|---|---|
| IEC 61000−4−2 Level 4 compliance | ±30 kV contact discharge capability ensures robustness against real-world handling ESD in consumer electronics assembly and field use |
| Low dynamic resistance | 0.05 Ω limits voltage overshoot during fast-rising transients, reducing stress on downstream IC ESD structures |
| Controlled junction capacitance | 400 pF enables integration on USB 2.0 differential pairs without violating eye diagram mask requirements |
| UDFN2 footprint | 1.6 mm × 1.0 mm size allows placement within 2 mm of connector pins, minimizing PCB trace inductance and improving clamping efficacy |
Applications
| USB 2.0 Interface Protection | Mobile Device Charging Port |
|---|---|
Use Scenario: Protecting D+ and D− lines of USB 2.0 host/device ports against user-handling ESD and cable-discharge events. IC Role / Device Role: Unidirectional shunt clamp placed between each data line and ground, triggered only above 10 V reverse bias.

IC Role / Device Role: Single-channel ESD suppressor mounted directly at connector footprint, with cathode tied to chassis ground. Use Value: 400 pF capacitance avoids signal degradation at 480 Mbps, while ±30 kV rating exceeds IEC 61000−4−2 Level 4 requirement for handheld devices. |
| Industrial Human-Machine Interface | Automotive Infotainment USB Port |
Use Scenario: Securing front-panel USB ports on PLCs and HMIs exposed to factory-floor ESD risks.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD9X5.0ST5G | 5.0 V VRWM, 12 V VBR, 14 V VC @ 1 A - lower clamping but higher capacitance (650 pF) | Better suited for 3.3 V logic rails; less suitable for 5 V-tolerant USB 2.0 due to premature conduction | Select when protecting lower-voltage interfaces where tighter clamping margin is prioritized over bandwidth |
| CM1213A-04SO | 12 V VRWM, 15 V VBR, 25 V VC @ 60 A - higher clamping voltage, 300 pF capacitance | Quad-channel SOIC-8 package - occupies more board area, requires routing through package leads | Choose when multi-line protection is needed and layout space permits larger footprint with lead inductance penalty |
Compared with ESD9X5.0ST5G and CM1213A-04SO, NSPM0101MUT5G delivers optimal balance of 10 V working voltage headroom, 20 V clamping at full lightning surge, and minimal 400 pF loading-making it preferred for compact, high-speed USB 2.0 implementations where board space and signal fidelity are constrained.

FAQ
What is the maximum clamping voltage of NSPM0101MUT5G under IEC 61000−4−5 surge conditions?
The NSPM0101MUT5G exhibits a clamping voltage of 20 V when subjected to a 60 A, 8/20 µs lightning surge per IEC 61000−4−5. This value is measured at the device terminals under standardized test conditions and represents the peak voltage imposed on the protected circuit during worst-case surge events. The NSPM0101MUT5G maintains this performance across its specified operating temperature range without derating.
Does NSPM0101MUT5G support bidirectional ESD protection?
No, NSPM0101MUT5G is a unidirectional ESD protection diode, configured with cathode grounded and anode connected to the protected line. It conducts only during negative transients relative to ground and blocks positive voltage up to 10 V. For bidirectional protection, two NSPM0101MUT5G devices may be used in series opposition, though this increases capacitance and footprint-alternatives like NUP4201MR6T1G are purpose-built for bidirectional operation.
What is the junction capacitance of NSPM0101MUT5G and how does it affect USB 2.0 signal integrity?
The NSPM0101MUT5G has a junction capacitance of 400 pF at 0 V and 1 MHz. This value is measured under small-signal AC conditions and directly impacts high-speed differential signaling: at 480 Mbps USB 2.0 data rates, 400 pF introduces minimal insertion loss and jitter when placed close to the connector. Layout best practices-such as symmetric trace routing and ground plane continuity-ensure the NSPM0101MUT5G maintains signal eye opening within USB specification limits.
Is NSPM0101MUT5G qualified to AEC-Q200 for automotive use?
Yes, NSPM0101MUT5G is AEC-Q200 qualified per onsemi's product documentation and qualification reports. It meets stress test requirements including temperature cycling, humidity bias, mechanical shock, and ESD robustness for passive components. While not an active IC, its qualification confirms suitability for automotive infotainment USB ports where ISO 10605 and IEC 61000−4−2 compliance are mandatory. The NSPM0101MUT5G operates reliably from −40°C to +125°C ambient.
How does the dynamic resistance of NSPM0101MUT5G influence its clamping performance?
The NSPM0101MUT5G features a dynamic resistance of 0.05 Ω, measured using 100 ns TLP pulses between I/O pin and ground. This low value minimizes voltage overshoot during rapid transient onset-ensuring the actual clamped voltage stays near the specified 20 V at 60 A rather than spiking significantly higher. As a result, the NSPM0101MUT5G provides predictable, repeatable protection for sensitive transceivers without requiring additional series impedance to limit diode current.
