Product details
Overview
UCLAMP1061P.TNT from Semtech is a transient diverting suppressor (TDS) designed for high-energy EOS protection of 22V-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 24–40A, 20mΩ dynamic resistance, and 175pF junction capacitance - deployed in USB PD, USB Type-C, and industrial load switch input protection.
For engineers reviewing the UCLAMP1061P.TNT datasheet, pinout, applications, or equivalent options, key selection considerations include clamping stability across temperature and current, low dynamic resistance for flat voltage response, DFN-6 package layout constraints, and compatibility with 22V bus systems requiring robust surge immunity per IEC 61000-4-5.
Technical Context
The UCLAMP1061P.TNT uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit that senses overvoltage events and rapidly shunts transient current to ground. Unlike conventional TVS diodes, its clamping voltage remains nearly constant across the full 24–40A rated pulse range due to decreasing RDS(on) under surge conditions.
It operates over –40°C to +125°C, maintains stable 27.5–28V clamping up to 125°C, and delivers 1120W peak pulse power (8/20μs). Its 175pF capacitance at 22V and 1MHz enables use on moderate-speed data/power lines where low parasitic loading is required but ultra-low capacitance (<1pF) is not mandatory.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC or RMS operating voltage on protected line without leakage or degradation. |
| Clamping Voltage | 27.5–28V at 24–40A (1.2/50μs + 8/20μs combo wave, RS = 2Ω) - ensures downstream 22V-rated ICs (e.g., USB PD controllers) remain below damage threshold during surge. |
| Peak Pulse Current | 40A (8/20μs) - supports compliance with IEC 61000-4-5 Level 4 (±1kV, RS = 42Ω) on unsymmetrical lines. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds industrial and consumer ESD immunity requirements without derating. |
| Dynamic Resistance | 20mΩ (measured 1–40A, 8/20μs) - enables flat clamping behavior and minimizes voltage overshoot during fast-rising transients. |
| Junction Capacitance | 175pF at 22V, 1MHz - suitable for USB Type-C VBus, load switch inputs, and industrial I/O where signal integrity is secondary to surge robustness. |
Pinout & Package
UCLAMP1061P.TNT is housed in a RoHS-compliant, halogen-free DFN-6 package measuring 1.6mm × 1.6mm × 0.55mm with UL 94V-0 molding compound and lead-free terminal finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground connection - all three pins must be tied to low-inductance ground plane via multiple vias to sustain 40A surge current and minimize voltage bounce. |
| 4, 5, 6 | IN | Protected line input - all three pins connect in parallel to the same 22V bus or power rail; required for full 40A rating and optimal thermal/surge performance. |
Key Features
| Feature | Design Value |
|---|---|
| FET-based transient shunting | Replaces traditional TVS diodes with active switching - eliminates linear VC = VBR + IPP×RDYN rise, enabling stable clamping across current and temperature. |
| Constant clamping voltage | 27.5–28V maintained from 24A to 40A and –40°C to +125°C - simplifies margining for 22V system-level reliability without thermal derating. |
| High-energy surge handling | 1120W peak pulse power (8/20μs) - supports repeated lightning-surge events in industrial equipment and remote meters. |
| Low dynamic resistance | 20mΩ - reduces IR drop under surge, limiting voltage overshoot and enabling tighter protection margins for sensitive 22V ICs. |
| DFN-6 space efficiency | 1.6mm × 1.6mm footprint - saves >50% board area vs. SO-8 or SOT-23 TVS solutions while maintaining 40A capability. |
Applications
| USB Type-C Power Delivery Protection | Industrial Load Switch Input Protection |
|---|---|
|
Use Scenario: Protecting 20–22V VBus lines in USB Type-C ports supporting Power Delivery up to 100W. IC Role / Device Role / Timing Role: Primary EOS shunt device placed between connector and PD controller or load switch, clamping surges before they reach silicon. Use Value: Maintains 27.5–28V clamping across temperature - avoids overvoltage damage to PD controllers even at 125°C ambient, unlike TVS diodes whose clamping rises with temperature. |
Use Scenario: Safeguarding input terminals of industrial-grade load switches (e.g., HS2950P) exposed to lightning-induced surges in metering or robotics. IC Role / Device Role / Timing Role: Front-end transient diverter that routes 40A surge energy to ground before it stresses the load switch's internal FET gate oxide or drain-source junction. Use Value: Prevents latch-up or permanent failure of load switches by holding clamping voltage below their absolute maximum VDS rating during 1.2/50μs + 8/20μs combo-wave transients. |
| IoT Device Power Rail Protection | Storage Device 22V Bus Protection |
|
Use Scenario: Securing 22V auxiliary rails in battery-powered IoT gateways subjected to ESD during field servicing or connector mating. IC Role / Device Role / Timing Role: Single-component solution replacing multi-diode TVS arrays - handles ±30kV contact ESD and 4kV EFT bursts without degradation. Use Value: Eliminates need for external RC filters or staged protection, reducing BOM count while delivering repeatable 28V clamping after 1000+ ESD strikes. |
Use Scenario: Shielding 22V backup or auxiliary power buses in enterprise SSDs and NAS enclosures against AC-line coupled surges. IC Role / Device Role / Timing Role: Standalone surge protector mounted directly at power entry point, absorbing IEC 61000-4-5 Level 4 transients before reaching PMIC or storage controller. Use Value: Ensures uninterrupted operation during ±1kV surge tests by limiting voltage excursion to ≤28V - well below 30V tolerance of typical 22V-rated power management ICs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |

FAQ
What is the maximum continuous operating voltage for UCLAMP1061P.TNT?
The UCLAMP1061P.TNT has a reverse stand-off voltage (VRWM) of 22V, meaning it can safely operate continuously at up to 22V DC or RMS on the protected line without significant leakage or degradation. This makes it ideal for 20–22V USB PD VBus and industrial auxiliary rails where sustained voltage levels approach the protection threshold.
How does UCLAMP1061P.TNT achieve stable clamping across temperature?
UCLAMP1061P.TNT uses a surge-rated FET activated by a precision trigger circuit instead of a passive PN-junction TVS. As surge current increases, the FET's RDS(on) decreases, counteracting voltage rise - resulting in 27.5–28V clamping from –40°C to +125°C. This contrasts with conventional TVS diodes, whose clamping voltage rises with temperature.
Can UCLAMP1061P.TNT replace standard TVS diodes in USB Type-C designs?
Yes - UCLAMP1061P.TNT is explicitly validated for USB Type-C VBus protection in Semtech's reference designs. Its 27.5–28V clamping at 40A and ±30kV ESD rating meet or exceed requirements for 20V PD systems, and its flat clamping eliminates thermal derating concerns that plague traditional TVS solutions in compact, thermally constrained ports.
What is the recommended PCB layout for UCLAMP1061P.TNT?
Place UCLAMP1061P.TNT as close as possible to the protected connector. Connect all three IN pins (4,5,6) in parallel with a short, wide trace to the protected line, and tie all three GND pins (1,2,3) to a solid ground plane using ≥3 vias each. Avoid thermal pads - energy is dissipated in the silicon FET, not the package bottom.
Is UCLAMP1061P.TNT compliant with RoHS and halogen-free standards?
Yes - UCLAMP1061P.TNT is Pb-free, halogen-free, and fully compliant with RoHS and WEEE directives. Its molding compound meets UL 94V-0 flammability rating, and the lead finish is lead-free, supporting environmentally regulated industrial and consumer deployments without compliance overhead.
