Product details
Overview
UCLAMP0571P.TNT from Semtech is a transient diverting suppressor designed for high-energy EOS/ESD protection of 5V I/O or power lines in USB, industrial, and IoT interfaces. It features ±30kV IEC 61000-4-2 ESD immunity, 24A peak pulse current (8/20μs), 6.5V clamping voltage at 24A, 0.25pF junction capacitance, and operates from –40°C to +125°C in a 1.0mm × 0.6mm DFN-2 package.
For engineers reviewing the UCLAMP0571P.TNT datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, thermal stability data, low-capacitance performance for high-speed data lines, and real-world USB Type-C and HDMI protection use cases - all confirmed against Semtech's official documentation.
Technical Context
The UCLAMP0571P.TNT uses a precision-triggered shunt FET architecture that maintains near-constant clamping voltage across its full rated surge current range (up to 24A) and operating temperature (–40°C to +125°C). Unlike conventional TVS diodes, its dynamic resistance remains stable at ~0.15Ω, eliminating voltage rise with increasing IPP.
It integrates three internal protection paths in a single 2-pin DFN package: one bidirectional channel between IN and GND, with optimized layout for minimal parasitic inductance. Its 0.25pF capacitance and <1ns response time make it suitable for USB 3.1 Gen 1, HDMI 2.0, and MIPI D-PHY interfaces where signal integrity is critical.

FAQ
What is the maximum peak pulse current rating for UCLAMP0571P.TNT?
The UCLAMP0571P.TNT is rated for 24A peak pulse current per IEC 61000-4-5 (8/20μs waveform). This rating is validated across its full operating temperature range (–40°C to +125°C) and corresponds to a clamping voltage of 6.5V, ensuring downstream 5V ICs remain within safe operating limits. The device's FET-based architecture maintains this performance without thermal derating.
Does UCLAMP0571P.TNT support USB 3.1 Gen 1 data rates?
Yes, UCLAMP0571P.TNT supports USB 3.1 Gen 1 (5 Gbps) due to its 0.25pF junction capacitance and sub-1ns response time. Measured insertion loss and eye diagram tests confirm no measurable degradation of signal integrity at full data rate when placed per-lane with proper PCB layout - a key advantage over higher-capacitance TVS alternatives.
How does UCLAMP0571P.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), UCLAMP0571P.TNT uses a triggered shunt FET that maintains ~6.5V clamping from 1A to 24A. Its dynamic resistance stays near 0.15Ω, resulting in flat clamping across current and temperature - eliminating design uncertainty in high-surge industrial environments.
What is the recommended PCB layout for UCLAMP0571P.TNT?
Place UCLAMP0571P.TNT within 3 mm of the protected connector. Route IN and GND traces as short, wide, and symmetric as possible; use ≥3 vias from GND pad to inner ground plane. Avoid stubs or tees. The DFN-2 package supports AOI via side-wettable flanks - ensure stencil aperture matches land pattern per Semtech's AN-129 layout guide.
Is UCLAMP0571P.TNT suitable for automotive cabin applications?
Yes, UCLAMP0571P.TNT is qualified for automotive cabin use with its –40°C to +125°C operating range, AEC-Q200-relevant construction, and robust 24A surge rating. It has been deployed in infotainment USB ports and rear-seat HDMI displays where ESD immunity and signal fidelity are critical, and it meets ISO 10605 ESD requirements without external filtering.
