Product details
Overview
UCLAMP6061P.TNT from Semtech is a transient diverting suppressor designed for high-energy EOS/ESD protection of 6V-rated I/O or power lines in USB Type-C, industrial IoT, and load-switch interfaces. It delivers ±30kV IEC 61000-4-2 ESD immunity, 40A peak pulse current (8/20μs), 6V working voltage, and stable 9.5V clamping at 24A with <25mΩ dynamic resistance.
For engineers reviewing the UCLAMP6061P.TNT datasheet, pinout, applications, or equivalent options, this page provides verified package mapping, real-world clamping behavior across temperature, functional comparison to TVS diodes, and validated alternatives for 6V bus protection in compact DFN layouts.
Technical Context
The UCLAMP6061P.TNT uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit that turns on the shunt path when transient voltage exceeds breakdown. Unlike conventional TVS diodes, its clamping voltage remains nearly constant-9.5V at 24A and 9.6V at 40A-due to decreasing RDS(on) under surge conditions.
It operates from –40°C to +125°C with reverse leakage ≤600nA at 6V, junction capacitance of 175pF at 6V/1MHz, and thermal stability confirmed across –50°C to +150°C junction range. Its DFN 1.6×1.6×0.55mm package integrates three parallel input terminals (pins 4–6) and three ground terminals (pins 1–3) to minimize parasitic inductance and maximize surge current handling.

Applications
| USB Type-C Power Delivery Bus Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 6V VBUS lines in USB Type-C receptacles supporting up to 20V PD negotiation, where transient events may exceed 1kV (IEC 61000-4-5). IC Role / Device Role / Timing Role: Primary EOS shunt device placed adjacent to connector, clamping surges before they reach PD controller or load switch. Use Value: Maintains 9.5V clamping at full 40A surge-well below 12V damage threshold of common 6V-rated PD controllers like STUSB4500 or TUSB7320. |
Use Scenario: Safeguarding analog sensor supply rails (e.g., 6V excitation for strain gauges or RTDs) in factory-floor instrumentation exposed to EFT bursts and lightning-induced coupling. IC Role / Device Role / Timing Role: Low-leakage (<600nA) front-end protector on sensor VDD rail, placed before LDO regulator to prevent latch-up or burnout. Use Value: 175pF capacitance avoids filtering error in DC-coupled sensor paths; ±30kV ESD rating ensures robustness during manual handling and maintenance. |
| Load Switch Input Protection | IoT Gateway Power Input Protection |
Use Scenario: Shielding enable and input pins of 6V-rated load switches (e.g., TPS229xx, AP22653) against EOS from hot-plug events or backfeed transients in industrial control modules. IC Role / Device Role / Timing Role: Fast-acting shunt that limits voltage across load switch FET gate-source and drain-source during surge, preventing avalanche failure. Use Value: 25mΩ RDYN ensures <1V overshoot at 20A surge-keeping VGS and VDS within safe operating area of 6V-rated switches. |
Use Scenario: Securing 6V auxiliary power inputs on cellular/Wi-Fi IoT gateways deployed in remote locations subject to indirect lightning surges and EFT noise. IC Role / Device Role / Timing Role: First-line defense on main 6V input rail, coordinated with downstream ceramic fuses and LC filters to meet IEC 61000-4-5 Level 4 compliance. Use Value: 40A peak rating supports 2× safety margin above typical 20A surge test requirement; DFN package allows placement within 3mm of input connector per layout guidelines. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SP1003-01WTG | 6V working voltage, 30A IPP, 12V clamping at 24A, SOD-323 package | Higher clamping voltage (12V vs. 9.5V) limits use with tighter-margin 6V ICs; smaller 1.7×1.3mm footprint but single-pin I/O | Select when board space is more constrained than clamping voltage margin, and surge current requirement is ≤30A. |
| TPD6E004DR | 6V working voltage, 4A IPP per line, 12V clamping, 6-pin SON package with 4-channel configuration | Designed for multi-line protection (e.g., USB 2.0 D+/D− + VBUS + GND); insufficient for 40A single-line surge duty | Choose only for distributed low-energy protection across multiple 6V signals-not as a direct replacement for high-current bus clamping. |
Compared with UCLAMP6061P.TNT, SP1003-01WTG trades clamping performance for size, while TPD6E004DR offers channel count at the expense of peak current capability-making UCLAMP6061P.TNT the sole option among these three for 40A, 9.5V-clamped, single-line 6V bus protection in DFN form.

FAQ
What is the maximum clamping voltage of UCLAMP6061P.TNT at 40A surge current?
The UCLAMP6061P.TNT clamps at 9.6V when subjected to a 40A peak pulse current (8/20μs waveform with 1.2/50μs voltage component, RS = 2Ω). This value is measured across pins 4–6 to pins 1–3 and remains stable from –40°C to +125°C, confirming its suitability for 6V systems with narrow overvoltage tolerances. UCLAMP6061P.TNT achieves this via FET-based shunting rather than PN-junction conduction.
Does UCLAMP6061P.TNT require a thermal pad on the PCB?
No, UCLAMP6061P.TNT does not require a thermal pad. Its DFN 1.6×1.6mm package dissipates surge energy through its internal FET structure and relies on low-inductance grounding via pins 1–3 to the PCB ground plane. Layout guidelines specify using multiple vias under the GND pins-not a copper thermal slug-to minimize inductance and preserve clamping performance. UCLAMP6061P.TNT's thermal design is optimized for transient, not continuous, power dissipation.
Can UCLAMP6061P.TNT be used to protect USB 2.0 data lines?
UCLAMP6061P.TNT is not recommended for USB 2.0 data lines due to its 175pF junction capacitance, which would degrade signal integrity at 480Mbps. It is intended for 6V power or control lines (e.g., VBUS, CC, SBU, or load-switch EN/VIN). For USB 2.0 differential pairs, Semtech recommends low-capacitance devices like RClamp0524P (0.3pF) instead. UCLAMP6061P.TNT's design focus is high-current bus protection-not high-speed signal clamping.
How does UCLAMP6061P.TNT differ from standard TVS diodes in clamping behavior?
Unlike standard TVS diodes whose clamping voltage rises linearly with peak current (VC = VBR + IPP × RDYN), UCLAMP6061P.TNT maintains ~9.5V clamping from 1A to 40A due to its active FET shunt architecture. Its dynamic resistance drops under surge, yielding flat clamping independent of current magnitude or temperature-whereas TVS clamping can increase by >5V across the same range. This makes UCLAMP6061P.TNT more predictable in real-world surge events.
Is UCLAMP6061P.TNT compatible with lead-free reflow soldering processes?
Yes, UCLAMP6061P.TNT is fully compatible with standard lead-free reflow profiles (J-STD-020 compliant), including peak temperatures up to 260°C. Its DFN package uses lead-free terminal finish and UL 94V-0 molding compound, and it is rated for storage and operating temperatures up to +150°C junction. The device is supplied in tape-and-reel packaging (3,000 units/reel) and meets RoHS and REACH requirements. UCLAMP6061P.TNT has been qualified for industrial reflow reliability per Semtech's AEC-Q200-aligned stress testing.
