Product details
Overview
RCLAMP3552T.TNT from Semtech is a transient diverting suppressor (TDS) designed for high-energy EOS/ESD protection of 22V-rated power or I/O lines, featuring ±30kV IEC 61000-4-2 ESD immunity, 40A peak pulse current (8/20μs), 27.6V clamping at 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 RCLAMP3552T.TNT datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, DFN-6 package layout guidance, real-world clamping stability across temperature and current, and direct alternatives for 22V bus protection in high-reliability embedded and connectivity designs.
Technical Context
The RCLAMP3552T.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 threshold. Unlike conventional TVS diodes, its clamping voltage remains nearly constant (27.5–28V) across 24–40A IPP and −40°C to +125°C due to decreasing RDS(on) under surge conditions.
It operates with reverse stand-off voltage of 22V, breakdown voltage of 25–27.9V, and reverse leakage <600nA at VRWM. Its low 20mΩ dynamic resistance and 175pF capacitance at 22V/1MHz support robust protection without signal integrity degradation on high-speed or high-voltage interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC operating voltage on protected line without leakage or conduction. |
| Clamping Voltage | 27.6V at 40A (8/20μs) - ensures downstream ICs (e.g., USB PD controllers) remain below damage threshold during worst-case surges. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - meets highest industrial and consumer ESD immunity requirements without degradation. |
| Peak Pulse Current | 40A (8/20μs) - supports compliance with IEC 61000-4-5 Level 4 surge immunity for industrial equipment and USB PD inputs. |
| Dynamic Resistance | 20mΩ - enables stable clamping by minimizing voltage rise (ΔV = IPP × RDYN) across full surge current range. |
| Junction Capacitance | 175pF at 22V/1MHz - low enough to avoid signal distortion on 100Mbps+ power/data buses like USB Type-C VBUS. |
Pinout & Package
Package: DFN 1.6mm × 1.6mm × 0.55mm, 6-lead, Pb-free, RoHS/WEEE compliant, UL 94V-0 molding compound.
| 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 or power rail); parallel connection of all three pins ensures uniform current distribution and full 40A rating. |
Key Features
| Feature | Design Value |
|---|---|
| Constant Clamping Voltage | 27.5–28V across 24–40A IPP and −40°C to +125°C - eliminates derating concerns and simplifies margin analysis vs. TVS diodes. |
| FET-Based Shunt Architecture | Surge-rated MOSFET + precision trigger circuit - achieves lower dynamic resistance and superior thermal stability vs. PN-junction TVS. |
| High-Energy Surge Handling | 1120W peak pulse power (8/20μs) - sustains multi-kA-level transients common in industrial and automotive power rails. |
| Low-Leakage Protection | <600nA reverse leakage at 22V - prevents battery drain or bias shift in always-on IoT and portable applications. |
Applications
| USB Type-C Power Delivery | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting VBUS line in USB-C receptacles supporting up to 20V/5A PD negotiation against lightning-induced surges and connector hot-plug ESD. IC Role / Device Role / Timing Role: Primary EOS shunt protector placed directly at connector, clamping transients before they reach PD controller or load switch. Use Value: Maintains 27.6V clamping at 40A - stays 10V below typical 36V PD controller absolute max rating, enabling single-stage protection without overdesign. |
Use Scenario: Safeguarding input of high-side load switches (e.g., HS2950P) in remote meters, robotics, and factory automation systems exposed to 1kV/42Ω surges. IC Role / Device Role / Timing Role: Front-end transient diverter that limits voltage stress on internal FET gate oxide and drain-source junction during EOS events. Use Value: Prevents latch-up or permanent failure of load switch ICs by holding clamping voltage well below their 30V+ breakdown thresholds under full 40A surge. |
| IoT Edge Node Power Rails | Notebook/Tablet VBUS Protection |
Use Scenario: Securing 22V-capable auxiliary power inputs in battery-backed smart sensors and gateway devices subject to EFT bursts (±4kV, 5/50ns). IC Role / Device Role / Timing Role: Solid-state transient suppressor replacing traditional TVS arrays, delivering repeatable clamping without parameter drift after repeated surges. Use Value: 175pF capacitance avoids signal ringing on 22V bias rails feeding ADC references or PMIC enable lines, preserving measurement accuracy. |
Use Scenario: Protecting USB-C VBUS routing on thin-client motherboards where board space is constrained and thermal management is limited. IC Role / Device Role / Timing Role: Compact DFN-6 EOS protector mounted adjacent to connector, minimizing trace inductance to ensure sub-10ns response to ESD events. Use Value: 1.6mm × 1.6mm footprint saves >60% area vs. SO-8 TVS solutions while maintaining full 40A surge rating - critical for ultra-thin form factors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDS2211P | Identical functional specification, same DFN-6 package, identical pinout and electrical parameters - direct manufacturer-recommended replacement. | Same use cases: USB PD, load switch input, industrial 22V rails. | Select TDS2211P when sourcing from Semtech's standard production line; RCLAMP3552T.TNT is a branded variant with identical performance and qualification. |
| uClamp2411ZA | 24V working voltage, lower 24A IPP rating, higher 30V clamping at 24A, smaller 0.65pF capacitance - optimized for CC/SBU lines, not VBUS. | Intended for low-voltage, low-capacitance data-line protection (CC, SBU), not 22V power rail protection. | Not suitable as direct alternative for RCLAMP3552T.TNT - use only for auxiliary signal lines; insufficient surge rating and clamping for VBUS. |
Compared with TDS2211P, RCLAMP3552T.TNT offers identical protection performance and drop-in compatibility, while uClamp2411ZA serves a different voltage class and signal-integrity role - making TDS2211P the only functionally equivalent alternative for 22V power-line EOS suppression.

FAQ
What is the maximum continuous operating voltage for RCLAMP3552T.TNT?
The RCLAMP3552T.TNT has a reverse stand-off voltage (VRWM) of 22V, meaning it can continuously block up to 22V DC without significant leakage or conduction. This makes it suitable for protecting 20V USB PD VBUS lines and other 22V-rated power rails where sustained voltage operation is required.
How does RCLAMP3552T.TNT achieve stable clamping voltage across temperature and current?
RCLAMP3552T.TNT uses a surge-rated FET activated by a precision trigger circuit. As peak pulse current increases, the FET's RDS(on) decreases, counteracting voltage rise - resulting in near-constant clamping (27.5–28V) from −40°C to +125°C and 24–40A. This behavior is confirmed in the device's clamping vs. temperature and current curves.
Is RCLAMP3552T.TNT pin-compatible with TDS2211P?
Yes - RCLAMP3552T.TNT and TDS2211P share identical DFN-6 package dimensions, pin configuration (pins 1–3 = GND, pins 4–6 = IN), and electrical specifications. They are functionally and mechanically interchangeable, with no PCB or layout changes required when substituting between them.
What is the junction capacitance of RCLAMP3552T.TNT and why does it matter?
RCLAMP3552T.TNT exhibits 175pF junction capacitance at 22V and 1MHz. This value is low enough to avoid signal integrity issues on high-speed or high-voltage power rails (e.g., USB-C VBUS), while remaining high enough to sustain robust surge energy handling - striking a deliberate balance between protection strength and system-level noise immunity.
Can RCLAMP3552T.TNT be used for EFT protection in industrial environments?
Yes - RCLAMP3552T.TNT is rated for ±4kV EFT immunity per IEC 61000-4-4 (5/50ns, 5kHz and 100kHz bursts), making it suitable for industrial equipment, programmable logic controllers, and remote sensors exposed to repetitive fast transients on power or interface lines.
