Product details
Overview
ECLAMP8052P.TCT from Semtech is a transient diverting suppressor (TDS) designed for high-energy EOS protection of single 22V-rated I/O or power lines, featuring ±30kV IEC 61000-4-2 ESD immunity, 40A peak pulse current (8/20μs), 27.5–28V clamping voltage at 24–40A, and 20mΩ dynamic resistance - deployed in USB Type-C PD input protection and industrial load switch front-end circuits.
For engineers reviewing the ECLAMP8052P.TCT datasheet, pinout, applications, or equivalent options, key selection criteria include clamping stability across temperature and current, low dynamic resistance for flat VC response, DFN-6 package layout compatibility, and compliance with IEC 61000-4-2/4-4/4-5 surge standards.
Technical Context
ECLAMP8052P.TCT 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 (27.5–28V) from 24A to 40A due to decreasing RDS(on) under surge conditions.
The device operates over −40°C to +125°C, maintains <600nA reverse leakage at 22V, exhibits 175pF junction capacitance at 22V/1MHz, and delivers 1120W peak pulse power - enabling robust protection without thermal derating penalties typical of junction-based TVS devices.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC bus voltage before leakage or conduction onset. |
| Clamping Voltage | 27.5–28V at 24–40A (1.2/50μs + 8/20μs combo wave, RS=2Ω) - ensures protected ICs (e.g., USB PD controllers) remain below damage threshold during surge. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 industrial surge immunity requirements. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds Class 4 system-level ESD immunity for exposed connectors. |
| Dynamic Resistance | 20mΩ - enables flat clamping response and minimizes voltage overshoot during fast-rising transients. |
| Junction Capacitance | 175pF at 22V/1MHz - compatible with low-speed power/data lines (e.g., VBUS, CC, SBU); not suitable for >1Gbps differential pairs. |
Pinout & Package
Package: DFN-6 (1.6mm × 1.6mm × 0.55mm, RoHS-compliant, UL 94V-0 molding compound, lead-free finish).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground return path for surge current; all three pins must be connected to maximize current sharing and minimize parasitic inductance. |
| 4, 5, 6 | IN | Protected line input (e.g., VBUS, load switch input); parallel connection of all three pins ensures full 40A rating and uniform current distribution. |
Key Features
| Feature | Design Value |
|---|---|
| Constant clamping voltage vs. current | 27.5–28V across 24–40A range - eliminates need for oversized IPP margin to meet VC budget. |
| Temperature-stable clamping | Clamping voltage variation <0.5V from −40°C to +125°C - enables reliable protection in uncontrolled thermal environments. |
| Low dynamic resistance | 20mΩ - reduces IR drop during surge, minimizing voltage overshoot beyond clamping level. |
| High EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns, 5kHz & 100kHz bursts) - protects against repetitive switching noise in industrial control systems. |
Applications
| USB Type-C Power Delivery Input Protection | Industrial Load Switch Front-End Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDS2211P.C | Same functional design, identical electrical specs, and identical DFN-6 package; differs only in reel packaging (3,000 pcs/reel vs. ECLAMP8052P.TCT's unspecified quantity). | Valid for same USB PD, load switch, and industrial power rail use cases; no layout or performance trade-offs. | Select TDS2211P.C when standard Semtech reel configuration is required for automated assembly. |
| uClamp2411ZA.TCT | 24V working voltage, lower 20A IPP rating, higher 32V clamping at 12A, and 12pF capacitance - optimized for CC/SBU lines, not VBUS. | Intended for low-capacitance, low-voltage signaling lines (CC, SBU), not 22V power rails; unsuitable for 40A surge duty. | Choose uClamp2411ZA.TCT only for auxiliary USB-C signal lines; not a functional replacement for ECLAMP8052P.TCT on VBUS. |
Compared with TDS2211P.C, ECLAMP8052P.TCT offers identical protection performance but may differ in tape-and-reel logistics; versus uClamp2411ZA.TCT, ECLAMP8052P.TCT provides 2× higher surge current capability and 5V-lower clamping - making it the sole viable option for 22V power-line EOS suppression.

FAQ
What is the primary protection function of ECLAMP8052P.TCT?
ECLAMP8052P.TCT functions as a transient diverting suppressor that shunts high-energy EOS events - including IEC 61000-4-2 ESD, IEC 61000-4-5 surges, and IEC 61000-4-4 EFT - away from downstream components. It achieves this using a precision-triggered surge-rated FET, delivering stable 27.5–28V clamping at 40A without voltage rise across current or temperature ranges. This behavior distinguishes ECLAMP8052P.TCT from traditional TVS diodes.
Does ECLAMP8052P.TCT support USB Type-C Power Delivery applications?
Yes, ECLAMP8052P.TCT is explicitly validated for USB Type-C PD input protection, supporting nominal 20V operation and 22V maximum bus voltage. Its 27.5–28V clamping at 40A ensures USB PD controllers remain within safe operating voltage limits during lightning surges and hot-plug ESD events - even at +125°C ambient, where conventional TVS devices degrade significantly. The DFN-6 package allows placement directly at the connector.
What is the recommended PCB layout for ECLAMP8052P.TCT?
Place ECLAMP8052P.TCT as close as possible to the protected connector. Connect all three IN pins (4, 5, 6) via a single low-inductance trace to the protected line, and tie all three GND pins (1, 2, 3) directly to a solid ground plane using multiple vias. Avoid stubs or splits in GND traces. Do not add thermal pads - energy dissipation occurs internally via the FET channel, not junction heating. This layout preserves the 40A surge rating and minimizes voltage overshoot.
How does ECLAMP8052P.TCT 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), ECLAMP8052P.TCT maintains near-constant clamping (27.5–28V) from 24A to 40A due to its FET-based architecture and decreasing RDS(on) under surge. It also exhibits minimal temperature drift (<0.5V variation from −40°C to +125°C), whereas TVS clamping typically increases 10–15% over the same range - making ECLAMP8052P.TCT more predictable in thermally challenging deployments.
Is ECLAMP8052P.TCT RoHS and halogen-free compliant?
Yes, ECLAMP8052P.TCT is Pb-free, halogen-free, and fully compliant with RoHS and WEEE directives. Its DFN-6 package uses UL 94V-0 rated molding compound and lead-free terminal finish. The device carries no exemptions and meets JEDEC J-STD-020 moisture sensitivity level (MSL) 1 requirements - enabling standard reflow processing without baking.
