Product details
Overview
UCLAMP3061P.TNT from Semtech is a transient diverting suppressor designed for high-energy EOS protection of 30V-rated I/O or power lines in USB PD, Type-C, and industrial interfaces. It delivers ±30kV IEC 61000-4-2 ESD immunity, 40A peak pulse current (8/20μs), and a stable 33V clamping voltage across temperature and current range.
For engineers reviewing the UCLAMP3061P.TNT datasheet, pinout, applications, or equivalent options, key selection criteria include clamping stability under surge, low dynamic resistance, junction capacitance for high-speed line compatibility, and DFN package integration with USB Type-C layout constraints.
Technical Context
The UCLAMP3061P.TNT uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit that senses overvoltage events. Unlike conventional TVS diodes, it maintains near-constant clamping voltage due to decreasing RDS(on) under increasing surge current.
It operates across –40°C to +125°C, supports unsymmetrical line surge testing per IEC 61000-4-5 (±1kV, 1.2/50μs), and achieves ±4kV EFT immunity per IEC 61000-4-4 - all while delivering 175pF junction capacitance at 22V reverse bias and 20mΩ dynamic resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 30 V - defines maximum continuous DC or RMS operating voltage on protected line without leakage degradation |
| Clamping Voltage | 33 V at 40 A (8/20 μs) - ensures downstream ICs with 33V absolute max ratings remain within safe margin during worst-case surge |
| ESD Withstand | ±30 kV contact & air (IEC 61000-4-2) - exceeds Level 4 immunity for handheld and connector-facing interfaces |
| Peak Pulse Current | 40 A (8/20 μs) - meets IEC 61000-4-5 industrial surge requirements for 22V bus systems |
| Junction Capacitance | 175 pF at 22 V, 1 MHz - compatible with USB 2.0 and low-speed industrial data lines; not suitable for USB 3.x SS lanes |
| Dynamic Resistance | 20 mΩ - enables flat clamping response and minimizes voltage overshoot during fast-rising transients |
Pinout & Package
UCLAMP3061P.TNT is housed in a RoHS-compliant, halogen-free DFN package measuring 1.6 mm × 1.6 mm × 0.55 mm with wettable flank terminations. The package features three input terminals and three ground terminals arranged for low-inductance, high-current surge path routing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | Ground | Common return path for surge current; all three must be connected to minimize parasitic inductance and maximize 40A capability |
| Pins 4, 5, 6 | Input / Protected Line | Parallel-connected anode-side terminals tied directly to the line under protection (e.g., VBUS or CC line); enables uniform current sharing |
Key Features
| Feature | Design Value |
|---|---|
| FET-based transient diversion | Replaces traditional TVS diodes with active shunt switching, enabling constant clamping independent of surge amplitude |
| Stable clamping over temperature | Clamps at ~33 V from –40°C to +125°C - eliminates derating concerns in automotive or industrial enclosures |
| Low dynamic resistance | 20 mΩ measured between 1A–40A (8/20 μs) - reduces voltage overshoot and improves energy handling vs. TVS with fixed RDYN |
| High EFT immunity | ±4 kV per IEC 61000-4-4 (5/50 ns, 100 kHz & 5 kHz bursts) - protects against repetitive switching noise in motor drives and PLCs |
Applications
| USB Type-C Power Delivery Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting VBUS lines in USB-C receptacles supporting up to 30V PD profiles against lightning-induced surges and connector hot-plug ESD. IC Role / Device Role / Timing Role: Primary high-energy shunt suppressor placed adjacent to the connector, clamping transients before they reach the PD controller or load switch. Use Value: Maintains 33V clamping at full 40A surge and across temperature - prevents latch-up or gate oxide damage in 30V-rated PD controllers like STUSB4500 or TUSB7320. | Use Scenario: Safeguarding enable and input pins of industrial-grade e-fuses (e.g., TPS25982, MP6656) exposed to field wiring transients in remote meters or robotics. IC Role / Device Role / Timing Role: Front-end EOS guard device that limits voltage seen by the e-fuse's internal FET gate and drain, preventing avalanche failure during 1kV line-to-ground surges. Use Value: Clamping stability ensures e-fuse remains within its 33V absolute maximum rating even at 125°C ambient - avoids thermal runaway during sustained overload conditions. |
| IoT Sensor Hub Bus Protection | Storage Device Power Rail Protection |
Use Scenario: Shielding 3.3V–30V mixed-voltage sensor buses (e.g., CAN FD, RS-485, or analog front-ends) in edge gateway designs subject to ESD from human interaction or cable coupling. IC Role / Device Role / Timing Role: Single-device solution for multi-node bus protection where space-constrained PCBs require minimal footprint and no external biasing. Use Value: 175pF capacitance avoids signal integrity degradation on sub-10MHz buses; ±30kV ESD rating covers both user-accessible ports and internal interconnects. | Use Scenario: Securing 24V/30V auxiliary rails in NVMe SSD enclosures or SAS backplanes exposed to hot-swap transients and chassis ground bounce. IC Role / Device Role / Timing Role: Secondary-level rail clamp positioned after bulk filtering but before PMIC inputs, complementing upstream ceramic TVS arrays. Use Value: 1120W peak pulse power rating handles multiple sequential surges without parametric shift - critical for mission-critical storage firmware reliability. |
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, 27.5V clamping at 40A, same DFN-6 package | Optimized for 22V systems (e.g., USB PD 3.0 20V profile); lower clamping than UCLAMP3061P.TNT but narrower voltage range | Select when protecting 22V rails where tighter clamping margin is required and 30V operation is unnecessary |
| UCLAMP3301P.TNT | 33V working voltage, 36V clamping at 40A, identical footprint and pinout | Rated for higher bus voltages (e.g., 28V industrial supplies); slightly higher clamping threshold trades margin for extended voltage range | Choose for 33V systems requiring headroom above 30V nominal, such as 24V+10% industrial rails or PoE++ injectors |
Compared with TDS2211P and UCLAMP3301P.TNT, UCLAMP3061P.TNT offers optimal balance for 30V applications - delivering lower clamping than the 33V variant while supporting wider operating margins than the 22V TDS2211P, all in a drop-in compatible DFN-6 package.

FAQ
What is the maximum continuous operating voltage for UCLAMP3061P.TNT?
The UCLAMP3061P.TNT has a reverse stand-off voltage (VRWM) of 30 V, meaning it can reliably protect circuits operating continuously up to 30 V DC without significant leakage or degradation. This makes UCLAMP3061P.TNT ideal for 24V industrial rails and USB PD 30V profiles where sustained voltage stress is present.
How does UCLAMP3061P.TNT achieve stable clamping across temperature?
UCLAMP3061P.TNT uses a precision-triggered FET architecture instead of a passive PN-junction. As surge current increases, the FET's RDS(on) decreases, counteracting voltage rise - resulting in consistent ~33 V clamping from –40°C to +125°C. This behavior is verified in the UCLAMP3061P.TNT datasheet's clamping vs. temperature curves.
Can UCLAMP3061P.TNT be used on USB 3.2 SuperSpeed differential pairs?
No - UCLAMP3061P.TNT has 175 pF junction capacitance at 22 V, which would severely degrade signal integrity on USB 3.2 Gen 1/2 differential lanes (requiring <0.3 pF). For those lines, low-capacitance devices like RClamp3371ZC are recommended; UCLAMP3061P.TNT is intended for VBUS, CC, SBU, or power rails only.
What is the recommended PCB layout for UCLAMP3061P.TNT to achieve full 40A surge rating?
To achieve the full 40A (8/20 μs) rating, all three GND pins (1, 2, 3) and all three IN pins (4, 5, 6) must be shorted together using wide, low-inductance traces. Place UCLAMP3061P.TNT within 3 mm of the protected connector, use ≥4 vias per GND pad to inner ground planes, and avoid stubs or splits in the surge path - layout guidelines are specified in the UCLAMP3061P.TNT datasheet Figure 7.
Is UCLAMP3061P.TNT RoHS and REACH compliant?
Yes - UCLAMP3061P.TNT is Pb-free, halogen-free, and fully compliant with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Its molding compound meets UL 94V-0 flammability rating, and lead finish is 100% matte tin, as confirmed in the official Semtech product documentation for UCLAMP3061P.TNT.
