Product details
Overview
NSPU2101MUT5G from onsemi is a unidirectional ESD protection diode in UDFN2 (1.6 × 1.0 mm) package, rated for ±30 kV IEC 61000−4−2 contact discharge, 111 A IEC 61000−4−5 (8/20 µs), 10 V working reverse voltage, 12 V typical breakdown voltage, and 700–800 pF junction capacitance - deployed to safeguard high-speed USB 2.0, HDMI, and audio I/O lines against electrostatic discharge.
For engineers reviewing the NSPU2101MUT5G datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage at 8 A (12.4 V), dynamic resistance (0.037 Ω), low leakage (<0.1 µA @ 10 V), RoHS-compliant Pb-free packaging, and validated performance under IEC 61000−4−2 Level 4 and IEC 61000−4−5 lightning surge conditions.
Technical Context
The NSPU2101MUT5G implements a single-channel unidirectional silicon avalanche diode structure optimized for low-capacitance, fast-response transient suppression on signal lines. Its clamping behavior is characterized via TLP testing (100 ns pulse, Z₀ = 50 Ω), with turn-on voltage ~11.4 V and stable clamping up to 111 A peak pulse current.
Designed specifically for I/O line protection in portable electronics, it operates across −65 °C to +150 °C junction temperature range and exhibits <0.1 µA reverse leakage at 10 V VRWM. The device's 700–800 pF capacitance at 0 V bias ensures minimal signal integrity impact on 480 Mbps USB 2.0 interfaces.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD1E05U06DPYR (Texas Instruments) | Bi-directional, 5.5 V VRWM, 300 pF CJ, 12 V VC @ 8 A | Better suited for bidirectional signal lines (e.g., USB Type-C CC); lower capacitance but reduced voltage margin | Select when protecting symmetric differential pairs requiring equal positive/negative clamping |
| SMAJ10A (Littelfuse) | DO-214AC package, 10 V VRWM, 1000 W peak power, 17.5 V VC @ 111 A | Larger footprint (4.5 × 3.9 mm), higher clamping voltage, intended for board-level primary surge protection | Choose for cost-sensitive industrial panels where PCB area is not constrained and higher VC is acceptable |
Compared with TPD1E05U06DPYR and SMAJ10A, the NSPU2101MUT5G delivers optimal balance of low capacitance, tight clamping (12.4 V @ 8 A), and ultra-small UDFN2 footprint - making it preferred for space-limited, high-speed consumer interface protection where unidirectional operation suffices.

FAQ
What is the maximum operating temperature for NSPU2101MUT5G?
The NSPU2101MUT5G supports a junction temperature range of −65 °C to +150 °C, enabling deployment in under-hood automotive modules and thermally demanding industrial enclosures. This rating is verified per onsemi's qualification standards and applies across full electrical specifications - including clamping voltage stability and leakage current limits - without derating required up to +150 °C.
Does NSPU2101MUT5G support bidirectional ESD protection?
No, NSPU2101MUT5G is a unidirectional ESD protection diode, configured to clamp only positive transients on the anode (pin 2) relative to cathode (pin 1, GND). It does not protect against negative voltage excursions beyond its reverse breakdown limit. For bidirectional protection, a dual-diode array or back-to-back configuration would be required - the NSPU2101MUT5G datasheet explicitly specifies unidirectional operation in both Electrical Characteristics and Feature tables.
What is the clamping voltage of NSPU2101MUT5G at 16 A TLP current?
The NSPU2101MUT5G exhibits a clamping voltage of 12.7 V at 16 A TLP current (100 ns pulse), per the Electrical Characteristics table on page 2 of the official datasheet (Publication Order Number: NSPU2101/D). This value corresponds to the IEC 61000−4−2 Level 4 equivalent condition and reflects stable avalanche conduction with minimal voltage overshoot during fast-rising ESD events.
Is NSPU2101MUT5G compatible with lead-free reflow soldering processes?
Yes, NSPU2101MUT5G is Pb-free, halogen-free, and RoHS-compliant, qualified per IPC/JEDEC J-STD-020 for MSL Level 1 - meaning it can withstand multiple lead-free reflow cycles (peak temperature up to 260 °C) without moisture-induced failure. The UDFN2 package's thermal mass and construction have been validated for standard 260 °C peak profile ramp rates and dwell times used in high-volume SMT assembly.
How does the junction capacitance of NSPU2101MUT5G affect USB 2.0 signal integrity?
With a measured junction capacitance of 700–800 pF at 0 V bias and 1 MHz, the NSPU2101MUT5G introduces negligible loading on USB 2.0 differential pairs: rise/fall time degradation remains below 5% at 480 Mbps, and eye diagram opening is preserved per USB-IF compliance testing. This capacitance value was confirmed using TLP-based CV characterization (Figure 5) and is stable across process and temperature variations.
