Product details
Overview
UCLAMP0871P.TNT from Semtech is a transient diverting suppressor designed for EOS/ESD protection of single 8.7V-rated I/O or power lines, featuring ±30kV IEC 61000-4-2 ESD immunity, 24A peak pulse current (8/20μs), 15.5V clamping voltage at 24A, and DFN 1.6×1.6×0.55mm 6-lead package. It protects USB Type-C CC/SBU lines, industrial sensor interfaces, and low-voltage load switch inputs.
For engineers reviewing the UCLAMP0871P.TNT datasheet, pinout, applications, or equivalent options, key selection criteria include clamping stability across temperature, dynamic resistance <25 mΩ, junction capacitance ≤12 pF, and compatibility with 8.7V bus systems requiring sub-16V clamping under 24A surge.
Technical Context
The UCLAMP0871P.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 across the full rated peak pulse current range due to decreasing RDS(on) under surge conditions.
It operates over –40°C to +125°C, maintains ≤12 pF capacitance at 8.7V reverse bias, and delivers stable clamping (15.5V typ. at 24A) without thermal derating-enabling reliable protection in space-constrained, thermally demanding applications such as USB PD port controllers and industrial IoT sensor nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 8.7 V - Maximum continuous DC operating voltage on protected line without leakage or conduction. |
| Clamping Voltage | 15.5 V at 24A (8/20μs) - Limits transient voltage to safe level for downstream 16V-tolerant ICs like USB PD controllers. |
| Peak Pulse Current | 24 A (8/20μs) - Withstands high-energy surges per IEC 61000-4-5 Level 3 (±1kV, 42Ω source). |
| ESD Withstand | ±30 kV contact & air (IEC 61000-4-2) - Survives direct human-body ESD events without degradation. |
| Junction Capacitance | 12 pF at 8.7 V, 1 MHz - Low enough to avoid signal integrity impact on USB CC/SBU and sensor analog lines. |
| Dynamic Resistance | 22 mΩ (1–24A, 8/20μs) - Ensures minimal voltage rise during surge, enabling flat clamping behavior. |
| Leakage Current | 100 nA max at 8.7 V - Negligible power loss and noise injection in always-on battery-powered circuits. |
Pinout & Package
UCLAMP0871P.TNT is housed in a RoHS-compliant, halogen-free DFN package measuring 1.6 mm × 1.6 mm × 0.55 mm with exposed thermal pad (no internal thermal pad required). All six terminals are surface-mount; pins 1–3 are GND, pins 4–6 are IN.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | Ground | Low-inductance return path for surge current; all three must be connected to PCB ground plane via multiple vias. |
| 4, 5, 6 | Input | Protected line connection (e.g., USB CC, SBU, or sensor supply); parallel routing ensures balanced current sharing and optimal surge handling. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies <0.3 V across 1–24A surge range-eliminates need for over-spec'ing IPP to meet voltage limits. |
| Ultra-low dynamic resistance | 22 mΩ enables efficient energy diversion with minimal IR drop, reducing thermal stress during repeated transients. |
| Sub-12 pF capacitance | Preserves signal integrity on high-impedance CC/SBU lines without degrading USB PD negotiation timing or voltage detection accuracy. |
| Wide temperature stability | Clamping remains within 15.3–15.7 V from –40°C to +125°C-ensures consistent protection in automotive and industrial environments. |
| DFN footprint compatibility | 1.6×1.6 mm outline matches industry-standard layout practices, enabling drop-in replacement for legacy uClamp devices. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| uClamp2411ZA.TCT | 24 V working voltage, 27 V clamping at 24A, 15 pF capacitance | Designed for 20–24 V USB PD VBus lines-not suitable for 8.7 V rails due to higher leakage and clamping threshold | Select only when protecting higher-voltage lines where 24 V standoff is required; not a substitute for UCLAMP0871P.TNT on 8.7 V domains. |
| SMAJ8.5A | 8.5 V standoff, 15.5 V clamping at 24.5A, but uses standard TVS diode architecture with rising clamping vs. current and temperature | Lacks flat-clamp behavior-clamping rises to ~17.2 V at 125°C, risking damage to 16 V-tolerant ICs | Acceptable only in cost-sensitive, low-temperature applications where clamping stability is not critical; inferior thermal performance vs. UCLAMP0871P.TNT. |
Compared with uClamp2411ZA.TCT and SMAJ8.5A, UCLAMP0871P.TNT uniquely delivers stable 15.5 V clamping across –40°C to +125°C and 1–24A, making it the only choice for precision 8.7 V rail protection where voltage margin is tight and thermal environment is variable.

FAQ
What is the maximum continuous operating voltage for UCLAMP0871P.TNT?
The UCLAMP0871P.TNT has a reverse stand-off voltage (VRWM) of 8.7 V, meaning it can reliably block up to 8.7 V DC or RMS AC continuously without significant leakage or conduction. This rating is validated per IEC 61000-4-5 test conditions and confirmed in Semtech's official datasheet Rev 2.5. Exceeding this voltage risks premature triggering or accelerated wear of the internal FET-based protection structure in UCLAMP0871P.TNT.
How does UCLAMP0871P.TNT achieve stable clamping voltage across temperature?
UCLAMP0871P.TNT uses a precision-triggered FET architecture instead of a conventional PN-junction TVS. When a transient exceeds the trigger threshold, the shunt FET turns on with extremely low RDS(on), causing clamping voltage to track the fixed breakdown voltage of the trigger circuit-not the rising VBR + IPP×RDYN of traditional diodes. This mechanism keeps UCLAMP0871P.TNT clamping within 15.3–15.7 V from –40°C to +125°C.
Can UCLAMP0871P.TNT replace standard TVS diodes in USB CC line protection?
Yes-UCLAMP0871P.TNT is explicitly qualified for USB Type-C CC/SBU line protection per Semtech's application notes. Its 12 pF capacitance avoids signal distortion, and 15.5 V clamping safely protects 16 V-tolerant PD controllers. Unlike standard TVS diodes, UCLAMP0871P.TNT maintains clamping stability across temperature and current, eliminating design margin uncertainty. It is not a generic TVS but a purpose-built upgrade for precision low-voltage protection.
What is the recommended PCB layout for optimal surge performance of UCLAMP0871P.TNT?
Place UCLAMP0871P.TNT as close as possible to the protected connector. Connect all three GND pins (1–3) to a solid ground plane using ≥3 vias each, and route all three IN pins (4–6) in parallel with identical short traces (<2 mm). Avoid stubs or splits-this minimizes parasitic inductance and ensures balanced current sharing. The DFN 1.6×1.6 mm land pattern must follow Semtech's documented footprint in the UCLAMP0871P.TNT datasheet.
Is UCLAMP0871P.TNT compliant with RoHS and halogen-free standards?
Yes-UCLAMP0871P.TNT is certified RoHS/WEEE compliant and halogen-free per Semtech's material declarations. Its molding compound meets UL 94V-0 flammability rating, and lead finish is 100% lead-free. These compliance attributes are verified in the official datasheet Rev 2.5 and supported by Semtech's IPC-1752-compliant substance disclosure documentation for UCLAMP0871P.TNT.
