Product details
Overview
RCLAMP3624T.TCT from Semtech is a transient diverting suppressor (TDS) designed for high-energy EOS/ESD protection of 22V-rated power or data lines in USB Type-C, USB PD, and industrial interfaces. It delivers ±30kV IEC 61000-4-2 ESD immunity, clamps at 27.5–28V under 40A 8/20μs surge, maintains <20mΩ dynamic resistance, and operates from –40°C to +125°C in a 1.6mm × 1.6mm DFN-6 package.
For engineers reviewing the RCLAMP3624T.TCT datasheet, pinout, applications, or equivalent options, this page provides verified electrical parameters, functional pin mapping, real-world use cases in USB PD bus protection and load switch input safeguarding, and validated alternative parts with documented differences in clamping behavior and voltage rating.
Technical Context
RCLAMP3624T.TCT uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit that senses overvoltage events. Unlike conventional TVS diodes, its clamping voltage remains nearly constant across 24–40A peak pulse current due to decreasing RDS(on) under surge conditions.
The device features three parallel input terminals (Pins 4–6) and three ground terminals (Pins 1–3), enabling low-inductance, high-current path routing. Its 175pF junction capacitance at 22V and 1MHz supports robust protection without signal integrity compromise on moderate-speed buses.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - matches nominal USB PD bus voltage and ensures reliable standoff during normal operation. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs) - stays below 30V damage threshold of common USB PD controllers and load switches. |
| ESD Rating | ±30kV contact & air (IEC 61000-4-2) - exceeds Level 4 immunity requirements for consumer and industrial end equipment. |
| Peak Pulse Current | 40A (8/20μs) - satisfies IEC 61000-4-5 Level 3 surge immunity for industrial and USB PD applications. |
| Dynamic Resistance | 20mΩ - enables stable clamping and minimizes voltage overshoot during fast-rising transients. |
| Junction Capacitance | 175pF at 22V, 1MHz - low enough to avoid signal degradation on USB 2.0 and auxiliary lines, but not superspeed lanes. |
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 |
|---|---|---|
| Pins 1, 2, 3 | Ground (GND) | Low-inductance return path for surge current; all three must be connected to maximize current handling and thermal dissipation. |
| Pins 4, 5, 6 | Input (IN) | Parallel-connected protected line terminals; enable distributed current sharing and reduce trace inductance in high-surge designs. |
Key Features
| Feature | Design Value |
|---|---|
| FET-based clamping architecture | Delivers flat clamping voltage across full 24–40A surge range-unlike TVS diodes whose VC rises linearly with IPP. |
| Temperature-stable clamping | Maintains 27.5–28V clamping from –40°C to +125°C-critical for industrial and automotive-adjacent deployments. |
| Low dynamic resistance | 20mΩ enables efficient energy shunting and reduces voltage overshoot during sub-100ns ESD events. |
| High-energy surge rating | 1120W peak pulse power (8/20μs) supports repeated lightning-induced surges per IEC 61000-4-5. |
Applications
| USB Type-C Power Delivery Bus Protection | Load Switch Input Protection |
|---|---|
Use Scenario: Protecting VBus lines in USB Type-C receptacles supporting up to 20V/5A PD negotiation. IC Role / Device Role / Timing Role: Transient diverting suppressor placed between connector and PD controller or load switch input. Use Value: Prevents damage to downstream PD controllers by clamping surges to ≤28V-well below their 30V absolute maximum rating-even at 125°C ambient. |
Use Scenario: Safeguarding enable and input pins of industrial-grade load switches (e.g., HS2950P) against lightning-induced surges. IC Role / Device Role / Timing Role: Primary EOS protection element on VIN or EN inputs exposed to field wiring or long cables. Use Value: Keeps clamping voltage below internal FET breakdown thresholds, extending switch lifetime and avoiding latch-up in remote metering or robotics systems. |
| Industrial IoT Sensor Hub Inputs | USB-C Docking Station Power Rails |
Use Scenario: Protecting 22V-rated sensor interface rails in battery-powered edge gateways subjected to ESD during field maintenance. IC Role / Device Role / Timing Role: Standalone EOS protector on analog or digital supply rails feeding microcontrollers or ADCs. Use Value: Delivers ±30kV ESD immunity without degrading signal fidelity-enabling compact, unshielded enclosure designs for cost-sensitive IIoT nodes. |
Use Scenario: Securing 20V power delivery paths in multi-port USB-C docking stations with shared VBus distribution. IC Role / Device Role / Timing Role: Parallel-connected TDS device on main PD rail upstream of port controllers and multiplexers. Use Value: Handles simultaneous surge events across multiple ports via shared clamping, reducing BOM count versus discrete TVS per port. |
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 | Identical electrical specs and pinout; same DFN-6 package; differs only in tape-and-reel packaging (3,000 pcs/reel vs. RCLAMP3624T.TCT's standard reel quantity). | Direct drop-in replacement in PCB layout and schematic; identical thermal and surge performance. | Select when sourcing volume reels aligned with Semtech's standard packaging configuration. |
| uClamp2411ZA.TCT | 24V working voltage, lower 20A peak pulse current, higher 30V clamping voltage, and smaller 1.0mm × 1.0mm DFN-4 package. | Better suited for CC/SBU lines in USB-C where lower capacitance and space constraints dominate over high-energy surge needs. | Choose for auxiliary signal lines requiring tighter board area; not suitable for 22V power rail protection where 40A surge capability is required. |
Compared with RCLAMP3624T.TCT, TDS2211P.C offers identical protection performance and mechanical compatibility, while uClamp2411ZA.TCT trades surge capacity and clamping precision for size reduction-making it appropriate only for lower-energy signal-line roles.

FAQ
What is the primary protection function of RCLAMP3624T.TCT?
RCLAMP3624T.TCT functions as a transient diverting suppressor that shunts high-energy EOS/ESD events to ground using an integrated surge-rated FET. Unlike TVS diodes, it maintains a near-constant 27.5–28V clamping voltage across its full 40A surge rating and operating temperature range, making RCLAMP3624T.TCT ideal for protecting sensitive 22V-rated USB PD controllers and load switches.
How does RCLAMP3624T.TCT differ from standard TVS diodes in clamping behavior?
RCLAMP3624T.TCT uses a triggered FET architecture that yields flat clamping voltage (27.5–28V) from 24A to 40A, whereas standard TVS diodes exhibit linear VC = VBR + IPP × RDYN rise. This means RCLAMP3624T.TCT avoids dangerous voltage overshoot at high surge currents and maintains consistent protection margins across temperature-key advantages confirmed in RCLAMP3624T.TCT's datasheet Figures 3 and 4.
Can RCLAMP3624T.TCT be used on USB 3.1/3.2 SuperSpeed differential pairs?
No-RCLAMP3624T.TCT is not suitable for USB SuperSpeed lanes due to its 175pF junction capacitance, which would severely degrade signal integrity. For those lines, Semtech recommends ultra-low-capacitance devices like RClamp3371ZC (<0.25pF). RCLAMP3624T.TCT is intended for VBus, CC, SBU, or other moderate-speed lines where 22V standoff and 40A surge capability are required.
What is the recommended PCB layout for optimal performance of RCLAMP3624T.TCT?
Place RCLAMP3624T.TCT as close as possible to the protected connector, route Pins 4–6 together in a single short trace to the protected line, and connect Pins 1–3 directly to a solid ground plane using multiple vias. All six pins must be soldered-splitting GND or IN connections degrades surge current handling and increases parasitic inductance, compromising RCLAMP3624T.TCT's 40A capability.
Is RCLAMP3624T.TCT RoHS and REACH compliant?
Yes-RCLAMP3624T.TCT is Pb-free, halogen-free, and fully compliant with RoHS/WEEE directives. Its molding compound meets UL 94V-0 flammability rating, and the lead finish is lead-free, as specified in the official Semtech datasheet for RCLAMP3624T.TCT.
