Product details
Overview
UCLAMP2671P.TNT from Semtech is a transient diverting suppressor (TDS) designed for high-energy EOS protection of 26V-rated power or I/O lines, featuring ±30kV IEC 61000-4-2 ESD immunity, 40A peak pulse current (8/20μs), 27.5–28V clamping voltage at 40A, and 20mΩ dynamic resistance. It protects USB PD, Type-C VBUS, and industrial load switch inputs where stable clamping under temperature and current stress is critical.
For engineers reviewing the UCLAMP2671P.TNT datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability across 40A and −40°C to +125°C, low 175pF junction capacitance, DFN 1.6×1.6mm 6-lead package layout compatibility, and FET-based shunt architecture versus conventional TVS diodes.
Technical Context
The UCLAMP2671P.TNT uses a surge-rated MOSFET as its primary protection element, activated by a precision trigger circuit that senses overvoltage events above ~27.9V breakdown. Unlike standard TVS diodes, its clamping voltage remains nearly constant-27.5–28V-across the full 40A peak pulse range due to decreasing RDS(on) under surge conditions.
This architecture delivers superior thermal stability: clamping voltage variation is <0.5V from −40°C to +125°C, and peak pulse current capability remains rated up to +125°C. The device operates with reverse stand-off voltage of 26V, reverse breakdown at 29.5V (typ), and forward voltage of 0.5V at 1mA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 26V - defines maximum continuous DC bus voltage it can protect without leakage or conduction. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs) - ensures protected ICs (e.g., USB PD controllers) remain below damage threshold during worst-case surges. |
| ESD Rating | ±30kV contact & air (IEC 61000-4-2) - exceeds Level 4 immunity requirements for handheld and interface ports. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 industrial surge immunity for 1.2/50μs–8/20μs combination waveforms. |
| Junction Capacitance | 175pF at 26V, 1MHz - low enough for VBUS line protection without signal integrity impact on 5–20V DC power rails. |
| Dynamic Resistance | 20mΩ - enables near-constant clamping by minimizing IR drop increase as surge current rises. |
| Operating Temp | −40°C to +125°C - supports deployment in automotive cabin, industrial control, and outdoor IoT environments. |
Pinout & Package
UCLAMP2671P.TNT is housed in a RoHS-compliant, halogen-free DFN package measuring 1.6mm × 1.6mm × 0.55mm with exposed thermal pad (no internal thermal pad required; energy dissipated in silicon). All six terminals are surface-mount; pins 1–3 are GND, pins 4–6 are IN (bidirectional protection path).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground return for surge current; all three must be connected to maximize current sharing and minimize parasitic inductance. |
| 4, 5, 6 | IN | Protected line input (VBUS, power rail, or high-side I/O); parallel connection ensures uniform current distribution and 40A rating. |
Key Features
| Feature | Design Value |
|---|---|
| FET-based shunt architecture | Enables flat clamping voltage vs. current curve-27.5–28V across 1–40A-eliminating design margin inflation needed with TVS diodes. |
| Temperature-stable clamping | VC drift <0.5V over −40°C to +125°C, enabling reliable protection in uncontrolled thermal environments without derating. |
| Low dynamic resistance | 20mΩ ensures minimal voltage overshoot during fast-rising transients (e.g., ESD), reducing risk of downstream latch-up. |
| High-energy surge handling | 1120W peak pulse power (8/20μs) supports repeated industrial surge events without degradation or parametric shift. |
| DFN 1.6×1.6mm footprint | Reduces PCB area by >50% vs. SOT-23 or SOIC alternatives while maintaining 40A capability via multi-pin parallel routing. |
Applications
| USB Power Delivery (PD) Bus Protection | Industrial Load Switch Input Protection |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDS2211P | 22V working voltage, 27.5–28V clamping, same DFN 1.6×1.6mm package and pinout. | Optimized for ≤22V systems (e.g., legacy USB PD 3.0, 19V notebooks); lower VRWM reduces leakage at lower bias. | Select when protecting 19–22V rails where tighter voltage margin is acceptable and lower standby leakage is prioritized. |
| UCLAMP3301P.TNT | 33V working voltage, 35–36V clamping, identical architecture and package. | Suitable for 28–33V industrial buses (e.g., PoE++, 48V DC-DC intermediate rails); higher VBR increases ESD trigger threshold. | Choose for 28–33V systems requiring higher standoff; avoid in 26V designs due to elevated clamping above protected IC limits. |
Compared with TDS2211P and UCLAMP3301P.TNT, UCLAMP2671P.TNT fills the critical 24–26V window-matching USB PD 3.1 Extended Power Range (EPR) and 24V industrial PLC I/O-where 22V parts risk premature conduction and 33V parts fail to clamp below 30V damage thresholds.

FAQ
What is the maximum continuous operating voltage for UCLAMP2671P.TNT?
The UCLAMP2671P.TNT has a reverse stand-off voltage (VRWM) of 26V, meaning it can reliably protect DC power rails or I/O lines operating continuously up to 26V without significant leakage or conduction. This makes UCLAMP2671P.TNT ideal for USB PD 3.1 EPR (up to 28V) and 24V industrial buses where margin below 30V damage thresholds is essential.
How does UCLAMP2671P.TNT achieve stable clamping voltage across temperature and current?
UCLAMP2671P.TNT uses a surge-rated MOSFET shunt architecture instead of a pn-junction TVS. Its trigger circuit activates the FET at ~29.5V breakdown, and the FET's RDS(on) decreases under surge, yielding near-constant 27.5–28V clamping from 1A to 40A and −40°C to +125°C-unlike TVS diodes whose VC rises linearly with current and temperature.
Can UCLAMP2671P.TNT replace standard TVS diodes in existing designs?
Yes-UCLAMP2671P.TNT is a direct drop-in replacement for many 26V-rated TVS diodes in DFN 1.6×1.6mm packages, provided the PCB layout connects all three GND pins (1–3) and all three IN pins (4–6) as specified. Its lower, flatter clamping improves margin for sensitive PD controllers and load switches without changing board area or footprint.
What is the junction capacitance of UCLAMP2671P.TNT, and why does it matter?
UCLAMP2671P.TNT exhibits 175pF junction capacitance at 26V and 1MHz. This value is optimized for power rail protection-not high-speed data lines-so it avoids signal distortion on VBUS while remaining low enough to prevent excessive AC coupling or ripple injection into downstream regulators and controllers in the UCLAMP2671P.TNT application.
Is UCLAMP2671P.TNT compliant with industry surge and ESD standards?
Yes-UCLAMP2671P.TNT is explicitly rated for ±30kV contact and air discharge per IEC 61000-4-2, ±4kV EFT per IEC 61000-4-4, and 40A peak pulse current (8/20μs) per IEC 61000-4-5. These certifications are validated in Semtech's official datasheet and make UCLAMP2671P.TNT suitable for EN 55032/55035, UL 62368-1, and AEC-Q200-aligned designs.
