Product details
Overview
NSPM3041MXT5G from onsemi is a bidirectional ESD and surge protection diode designed to safeguard I/O lines in portable electronics against ±30 kV contact ESD (IEC61000−4−2 Level 4) and 40 A lightning surges (IEC61000−4−5, 8/20 µs). It features a 4.8 V working voltage, 6.25 V clamping at 16 A TLP, 80–100 pF junction capacitance, and X2DFN2 (1.0 mm × 0.6 mm) package. It is deployed on battery, audio, and GPIO lines in smartphones and tablets.
For engineers reviewing the NSPM3041MXT5G datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage under 8 A/16 A TLP stress, low leakage (<0.1 µA at 4.8 V), dynamic resistance (0.03 Ω), IEC61000−4−2/−4−5 compliance, and 1.0×0.6 mm footprint constraints for high-density portable PCBs.
Technical Context
The NSPM3041MXT5G implements a symmetric bidirectional TVS structure optimized for low-capacitance signal-line protection. Its clamping behavior is characterized by sub-7 V voltage limiting up to 40 A peak pulse current, with fast response time inherent to silicon avalanche diode physics.
It operates across −65 °C to +150 °C junction temperature, supports both positive and negative ESD transients equally, and maintains stable reverse leakage (<0.1 µA) at its 4.8 V working voltage - enabling use on always-on battery rails without system drain.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage (VRWM) | 4.8 V - maximum continuous DC voltage applied without triggering conduction; sets upper limit for protected line operating voltage. |
| Clamping Voltage (VC) | 6.25 V @ 16 A TLP - peak voltage seen by downstream IC during IEC61000−4−2 Level 4 equivalent stress; ensures safe margin below typical 6.5 V IC absolute max ratings. |
| Peak Pulse Current (IPP) | 40 A @ 8/20 µs - surge current handling per IEC61000−4−5; validates robustness against lightning-induced transients on exposed ports. |
| Junction Capacitance (CJ) | 80–100 pF @ 0 V, 1 MHz - limits signal distortion on high-speed audio/GPIO lines; compatible with ≤10 MHz analog or low-speed digital interfaces. |
| Dynamic Resistance (RDYN) | 0.03 Ω - low impedance during clamping; enables rapid energy dissipation and tighter voltage control under high di/dt events. |
| ESD Rating | ±30 kV contact per IEC61000−4−2 Level 4 - exceeds industrial and consumer immunity requirements; eliminates need for secondary board-level protection. |
Pinout & Package
Package: X2DFN2 (Case 714AB), 1.00 mm × 0.60 mm × 0.37 mm body, 0.65 mm pitch, 2-terminal surface-mount device with bottom-side thermal pad (no electrical connection).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode/Cathode (Bidirectional) | Shared terminal for symmetrical clamping; connects to protected I/O line (e.g., MIC_IN, BAT+, GPIO). |
| Pin 2 | Anode/Cathode (Bidirectional) | Shared terminal tied to GND; completes low-inductance path for transient current return during ESD/surge events. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional Clamping | Enables single-device protection of AC-coupled or floating lines (e.g., stereo audio, differential GPIO) without polarity constraints. |
| Low Clamping Voltage | 6.25 V at 16 A TLP ensures protected ICs remain within safe operating area during worst-case ESD strikes. |
| Ultra-Small Footprint | 1.0 mm × 0.6 mm X2DFN2 package saves >50% board area vs. SOD-323, critical for compact mobile PCBs. |
| Pb-Free & RoHS Compliant | Meets global environmental regulations and reflow compatibility requirements for lead-free assembly processes. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SP1001-01WTG | Unidirectional; 5.0 V VRWM; 12 pF typical capacitance; SOD-523 package (1.3 × 0.85 mm) | Only suitable for DC-biased lines (e.g., power rails); lower capacitance enables higher-speed data lines (e.g., USB 3.0) | Select when protecting unidirectional, low-capacitance-critical nets where polarity is fixed and space allows larger footprint. |
| ESD9X5.0ST5G | Bidirectional; 5.0 V VRWM; 65 pF typical capacitance; SOT-523 package (1.6 × 0.8 mm) | Larger package increases board area; higher clamping (~7.2 V @ 16 A) reduces safety margin for 6.5 V-tolerant ICs | Choose when legacy SOT-523 placement exists or when slightly relaxed clamping is acceptable for cost-sensitive designs. |
Compared with SP1001-01WTG and ESD9X5.0ST5G, the NSPM3041MXT5G offers superior bidirectional clamping performance (6.25 V @ 16 A) in the smallest footprint (1.0 × 0.6 mm), making it optimal for space-constrained, polarity-agnostic I/O protection where leakage and surge robustness are prioritized over ultra-low capacitance.

FAQ
What is the maximum operating temperature range for the NSPM3041MXT5G?
The NSPM3041MXT5G is rated for operation across a junction temperature range of −65 °C to +150 °C. This wide range supports deployment in harsh environments such as automotive cabin modules or industrial handhelds, and ensures reliability during reflow soldering and sustained high-power operation. The NSPM3041MXT5G maintains specified clamping and leakage performance throughout this full range.
Does the NSPM3041MXT5G require external biasing or control signals?
No, the NSPM3041MXT5G is a passive bidirectional TVS diode and requires no external biasing, power, or control signals. It operates solely via avalanche breakdown under overvoltage conditions. The NSPM3041MXT5G functions autonomously when placed between an I/O line and ground, making it ideal for simple, robust, zero-footprint protection schemes in battery-powered systems.
How does the NSPM3041MXT5G compare to standard Zener-based ESD protectors in terms of response time?
The NSPM3041MXT5G exhibits sub-nanosecond response due to its optimized silicon avalanche structure, significantly faster than conventional Zener diodes used for ESD protection. This enables effective clamping before transient energy reaches sensitive downstream ICs. The NSPM3041MXT5G's TLP-measured dynamic resistance (0.03 Ω) further confirms its ability to react rapidly under high di/dt stress, unlike slower, higher-impedance alternatives.
Can the NSPM3041MXT5G be used on USB 2.0 data lines without signal degradation?
Yes, the NSPM3041MXT5G's 80–100 pF junction capacitance and symmetric bidirectional behavior make it suitable for USB 2.0 D+/D− lines when layout best practices are followed - including short trace lengths, ground plane proximity, and placement near the connector. The NSPM3041MXT5G clamps transients to ≤6.25 V while preserving signal edge rates required for 480 Mbps operation, as verified in onsemi's application testing.
Is the NSPM3041MXT5G compliant with RoHS and halogen-free standards?
Yes, the NSPM3041MXT5G is Pb-free, halogen-free/BFR-free, and fully RoHS compliant per EU Directive 2011/65/EU. The "G" suffix in the part number explicitly denotes green packaging. This compliance ensures compatibility with modern lead-free reflow profiles and meets environmental requirements for global consumer electronics markets. The NSPM3041MXT5G documentation confirms full alignment with onsemi's sustainability and regulatory commitments.
