Product details
Overview
UCLAMP1071P.TNT from Semtech is a transient diverting suppressor designed for high-energy EOS/ESD protection of 10V-rated I/O or power lines in USB Type-C, USB PD, and industrial interfaces. It delivers ±30kV IEC 61000-4-2 ESD immunity, clamps at 12.5V (IPP = 24A), maintains <20mΩ dynamic resistance, and operates from –40°C to +125°C in a 1.6mm × 1.6mm DFN-6 package.
For engineers reviewing the UCLAMP1071P.TNT datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability across temperature, low capacitance (12pF @ 0V), ultra-low leakage (<100nA), and compatibility with 10V bus systems requiring robust surge immunity per IEC 61000-4-5.
Technical Context
The UCLAMP1071P.TNT uses a precision-triggered shunt FET architecture-not a conventional TVS diode-enabling near-constant clamping voltage (12.5V at 24A, 12.8V at 40A) independent of peak pulse current and temperature. Its trigger circuit activates the low-RDS(on) FET when transient voltage exceeds breakdown, routing surge energy to ground via three parallel input terminals and three dedicated GND pins.
This architecture eliminates the linear VC = VBR + IPP × RDYN dependency seen in standard TVS devices. Instead, clamping remains stable across –40°C to +125°C and supports 40A (8/20μs) peak pulse current while dissipating energy in the FET channel rather than the junction.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 10V - Matches nominal 10V bus systems (e.g., USB PD 3.0 fixed PDOs, industrial sensor buses). |
| Clamping Voltage (IPP = 24A) | 12.5V - Ensures protected ICs (e.g., USB PD controllers, load switches) remain below absolute maximum ratings during surge events. |
| Clamping Voltage (IPP = 40A) | 12.8V - Confirms <0.3V rise over 67% current increase, validating flat clamping performance critical for margin-sensitive designs. |
| Junction Capacitance | 12pF @ 0V - Low enough for USB 2.0 data lines and analog sensor inputs without signal integrity degradation. |
| Dynamic Resistance | 18mΩ - Enables efficient current shunting with minimal IR drop, reducing thermal stress and improving reliability under repeated surges. |
| ESD Withstand | ±30kV contact/air (IEC 61000-4-2) - Meets highest-level system-level ESD requirements for handheld and field-deployed equipment. |
| Peak Pulse Current | 40A (8/20μs, IEC 61000-4-5) - Supports common industrial surge immunity standards including ±1kV (1.2/50μs, RS = 42Ω). |

| Low 12pF junction capacitance | Preserves signal integrity on 480Mbps USB 2.0 lines and analog sensor interfaces without added termination or equalization. |
| ±30kV ESD immunity | Exceeds IEC 61000-4-2 Level 4 by 2×, enabling single-device compliance for handheld and portable electronics without external shielding. |
| –40°C to +125°C operation | Validated clamping stability across full industrial temperature range-no derating required for automotive under-hood or factory-floor environments. |
Applications
| USB Type-C Power Delivery Interface | Industrial Sensor Bus Protection |
|---|---|
Use Scenario: Protecting VBUS and CC lines in USB Type-C receptacles supporting up to 10V/3A PD profiles. IC Role / Device Role / Timing Role: Primary EOS suppressor placed directly at connector, clamping transients before they reach PD controller and port manager ICs. Use Value: Maintains 12.5V clamping at 24A even at 125°C-prevents latch-up or gate oxide damage in 12V-tolerant PD controllers where traditional TVS would exceed safe operating limits. |
Use Scenario: Safeguarding 10V analog sensor outputs (e.g., pressure, temperature transducers) in factory automation PLC modules. IC Role / Device Role / Timing Role: Front-end transient guard on sensor signal lines exposed to relay switching noise and nearby motor drives. Use Value: 12pF capacitance avoids filtering low-frequency sensor signals (DC–1kHz), while ±30kV ESD rating ensures immunity to operator touch events in ungrounded enclosures. |
| Load Switch Input Protection | IoT Edge Node Power Rail |
Use Scenario: Shielding input of high-side load switches (e.g., TPS229xx, AP22653) in battery-powered medical monitors and test equipment. IC Role / Device Role / Timing Role: Surge limiter placed between power source and load switch IN pin to prevent FET gate-source overvoltage failure. Use Value: Clamps at 12.8V under 40A surge-well below typical 16V max VGS rating of integrated load switches, eliminating need for external Zener clamping. |
Use Scenario: Securing 10V DC-DC output rails in compact IoT gateways with PoE+ or AC/DC adapters subject to lightning-induced surges. IC Role / Device Role / Timing Role: Secondary rail protector downstream of primary front-end surge suppressors, targeting fast-rising ESD and EFT events. Use Value: 18mΩ dynamic resistance allows full 40A surge current to be diverted with <0.72V overshoot-preserving downstream LDO regulation and MCU brown-out thresholds. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| UCLAMP1271P.TNT | 12V working voltage, 14.5V clamping at 24A, 15pF capacitance | Better suited for 12V systems (e.g., automotive body control modules); higher capacitance may affect high-speed signal integrity | Select UCLAMP1271P.TNT only if system nominal voltage exceeds 10.5V or if higher clamping margin is acceptable for protected ICs. |
| SMAJ10A | 10V standoff, 17.5V clamping at 24A, 200pF capacitance, ±30kV ESD | Standard TVS diode with voltage-dependent clamping; unsuitable for high-speed or low-capacitance interfaces | Choose SMAJ10A only for cost-sensitive, non-high-speed applications where 200pF capacitance and 17.5V clamping are acceptable (e.g., DC power input filtering). |
Compared with UCLAMP1071P.TNT, UCLAMP1271P.TNT offers higher voltage headroom but trades off signal integrity; SMAJ10A provides lower cost but sacrifices clamping precision, temperature stability, and bandwidth-making UCLAMP1071P.TNT the optimal choice for 10V USB PD, industrial sensors, and space-constrained IoT nodes.

FAQ
What is the maximum clamping voltage of UCLAMP1071P.TNT at 40A surge current?
The UCLAMP1071P.TNT clamps at 12.8V when subjected to a 40A (8/20μs) peak pulse current, as specified in its electrical characteristics table. This value is measured under standardized IEC 61000-4-5 combination waveform conditions (1.2/50μs voltage, 8/20μs current, RS = 2Ω). The flat clamping behavior confirms the FET-based architecture's ability to maintain tight voltage control across its full rated surge range.
Does UCLAMP1071P.TNT require a thermal pad connection on the PCB?
No, UCLAMP1071P.TNT does not require a soldered thermal pad. Its DFN-6 package dissipates surge energy primarily through the copper traces connected to its six terminals-three GND pins (1–3) and three IN pins (4–6)-and relies on low-inductance PCB layout (e.g., multiple vias to ground plane) rather than thermal conduction. The datasheet explicitly states "no thermal pad is needed" under transient conditions.
Can UCLAMP1071P.TNT be used to protect USB 2.0 data lines?
Yes, UCLAMP1071P.TNT is suitable for USB 2.0 data line protection due to its 12pF junction capacitance at 0V bias, which introduces negligible signal distortion at 480Mbps. However, it must be applied only to lines operating ≤10V-such as VCONN or auxiliary power paths-not differential D+/D− pairs, which require sub-0.5pF devices like RClamp3371ZC.
How does UCLAMP1071P.TNT differ from standard TVS diodes in clamping behavior?
Unlike standard TVS diodes whose clamping voltage rises linearly with peak pulse current (VC = VBR + IPP × RDYN), UCLAMP1071P.TNT uses a triggered shunt FET that maintains nearly constant clamping (12.5V to 12.8V from 24A to 40A). This eliminates temperature- and current-dependent voltage drift, ensuring predictable protection margins across industrial operating conditions.
Is UCLAMP1071P.TNT compatible with lead-free reflow soldering processes?
Yes, UCLAMP1071P.TNT is fully compatible with standard lead-free reflow profiles (JEDEC J-STD-020). Its DFN-6 package uses lead-free terminal finish and meets RoHS/WEEE requirements. The maximum peak temperature rating of 260°C for 30 seconds is validated in Semtech's packaging specifications, and no special preheat or cooling ramp rates are required.
