Product details
Overview
NSPM1042MUTBG from onsemi is a bidirectional ESD and surge protection diode in a 2-pin UDFN2 package, rated for ±30 kV IEC 61000−4−2 contact discharge, 200 A (8/20 µs) IEC 61000−4−5 lightning surge, and featuring 3.3 V / 4.8 V asymmetric reverse working voltages for differential signal line protection in high-speed interfaces.
For engineers reviewing the NSPM1042MUTBG datasheet, pinout, applications, or equivalent options, this device delivers low dynamic resistance (0.01 Ω), sub-10 V clamping at 200 A, and <480 pF junction capacitance - critical for USB 2.0, HDMI, and MIPI D-PHY data lines requiring robust ESD immunity without signal integrity degradation.
Technical Context
The NSPM1042MUTBG implements a symmetric bidirectional TVS structure with distinct forward and reverse breakdown thresholds (4.5–5.5 V Pin1→Pin2; 5.0–6.0 V Pin2→Pin1), enabling precise clamping across differential pairs. Its TLP-measured dynamic resistance of 0.014 Ω (Pin1→Pin2) and 0.01 Ω (Pin2→Pin1) ensures rapid voltage suppression during sub-100 ns ESD transients.
Designed for placement directly at I/O connectors, it operates over −65 °C to +150 °C junction temperature and maintains ≤0.1 µA reverse leakage at both VRWM ratings - supporting low-power always-on interfaces such as smartphone camera modules and automotive infotainment displays.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating | ±30 kV contact per IEC 61000−4−2 Level 4 - protects against worst-case human-body model discharges at board edge. |
| Surge Rating | 200 A (8/20 µs) per IEC 61000−4−5 - withstands induced lightning surges on exposed cables. |
| Clamping Voltage | 9.5 V max at 200 A (Pin2→Pin1) - limits transient voltage below IC absolute maximum ratings. |
| Reverse Working Voltage | 3.3 V (Pin1→Pin2) / 4.8 V (Pin2→Pin1) - matches common differential bus biasing schemes like USB D+/D−. |
| Junction Capacitance | 480 pF max at 0 V - enables use on 480 Mbps USB 2.0 lines without measurable eye diagram degradation. |
| Dynamic Resistance | 0.01 Ω (Pin2→Pin1) - minimizes voltage overshoot during fast-rising ESD events. |
Pinout & Package
NSPM1042MUTBG uses the UDFN2 (Case 517DF) 2.0 mm × 1.25 mm, 0.45–0.55 mm height, 1.3 mm pitch package with bottom-side thermal pad. Pin 1 and Pin 2 are symmetrical terminals with no internal polarity marking; bidirectional operation eliminates orientation constraints during placement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode/Cathode (bidirectional) | Common terminal for differential ESD path; connects to one side of protected signal pair (e.g., USB D+). |
| Pin 2 | Anode/Cathode (bidirectional) | Common terminal for differential ESD path; connects to complementary side (e.g., USB D−); no fixed polarity required. |
Key Features
| Feature | Design Value |
|---|---|
| Asymmetric VRWM | 3.3 V / 4.8 V rating enables optimal biasing for unbalanced differential buses without external resistors. |
| TLP-validated clamping | 5.55 V at 16 A TLP pulse - correlates directly to IEC 61000−4−2 Level 4 (±8 kV contact) performance. |
| Low capacitance profile | 300–480 pF across 0–5 V bias - preserves signal rise/fall times on 480 Mbps interfaces. |
| Pb-free, RoHS-compliant | Halogen-free/BFR-free UDFN2 package - meets IPC-J-STD-020 moisture sensitivity level 1 (MSL1) for reflow compatibility. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD2E001DRYR | Unidirectional, 5.5 V VRWM, 12 pF typical capacitance, SOT-5X3 package | Lower capacitance suits USB 3.0/PCIe; lacks 200 A surge rating and bidirectional symmetry | Select when ultra-low capacitance (<15 pF) is prioritized over lightning surge immunity. |
| SZ1.5SMC15AT3G | Unidirectional, 15 V VRWM, 200 W peak power, DO-214AB package | Higher clamping (~24 V), larger footprint, intended for DC power rail protection, not high-speed data | Choose only for 12–24 V supply line protection where speed and capacitance are irrelevant. |
Compared with TPD2E001DRYR and SZ1.5SMC15AT3G, the NSPM1042MUTBG uniquely combines bidirectional operation, 200 A surge capability, and sub-500 pF capacitance in a 2.0×1.25 mm footprint - making it the only option qualified for differential high-speed data line protection per IEC 61000−4−2 Level 4 and IEC 61000−4−5 Class 3.

FAQ
What is the maximum clamping voltage of the NSPM1042MUTBG at 200 A surge current?
The NSPM1042MUTBG exhibits a maximum clamping voltage of 9.5 V at 200 A (8/20 µs waveform, Pin 2 to Pin 1), as specified in the Electrical Characteristics table. This value ensures downstream ICs with 10 V absolute maximum ratings remain safely within operational limits during lightning-surge events. The NSPM1042MUTBG achieves this via low dynamic resistance and optimized silicon geometry.
Is the NSPM1042MUTBG suitable for USB 2.0 data line protection?
Yes, the NSPM1042MUTBG is explicitly designed for USB 2.0 data line protection. With 3.3 V / 4.8 V asymmetric VRWM, ≤480 pF capacitance, and ±30 kV ESD rating, it meets USB-IF ESD requirements while maintaining signal integrity up to 480 Mbps. The NSPM1042MUTBG's UDFN2 footprint allows placement within 3 mm of the USB connector for optimal protection efficacy.
Does the NSPM1042MUTBG require polarity-aware PCB layout?
No, the NSPM1042MUTBG is a fully bidirectional ESD protection diode with symmetrical conduction characteristics in both directions. Its pinout has no anode/cathode designation - Pin 1 and Pin 2 are functionally identical terminals. This eliminates orientation errors during automated placement and simplifies routing for differential pairs. The NSPM1042MUTBG's bidirectionality is confirmed by independent VBR and VC specifications for both Pin1→Pin2 and Pin2→Pin1 directions.
What is the junction temperature range for continuous operation of the NSPM1042MUTBG?
The NSPM1042MUTBG supports continuous operation across a junction temperature range of −65 °C to +150 °C, as defined in the Maximum Ratings table. This wide range enables reliable use in automotive under-hood environments, industrial control panels, and consumer devices subject to thermal cycling. The NSPM1042MUTBG's UDFN2 package provides efficient thermal coupling to the PCB, sustaining full-rated ESD performance throughout this range.
How does the NSPM1042MUTBG compare to standard unidirectional TVS diodes in HDMI protection?
The NSPM1042MUTBG outperforms standard unidirectional TVS diodes in HDMI protection due to its bidirectional clamping, asymmetric VRWM (3.3 V / 4.8 V), and 480 pF capacitance - all optimized for differential TMDS signaling. Unidirectional diodes require external biasing and exhibit higher effective capacitance in AC-coupled paths. The NSPM1042MUTBG's 0.01 Ω dynamic resistance also delivers tighter voltage control during fast HDMI hot-plug transients, reducing pixel corruption risk compared to alternatives.
