Product details
Overview
RCLAMP0522P.TCT from Semtech is a transient diverting suppressor designed for high-energy EOS protection of 22V-rated I/O or power lines, featuring ±30kV IEC 61000-4-2 ESD immunity, 40A (8/20μs) peak pulse current handling, and stable 27.5–28V clamping across temperature and current range-used in USB Type-C PD bus protection.
For engineers reviewing the RCLAMP0522P.TCT datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability under surge, low dynamic resistance (<20 mΩ), junction capacitance (175 pF), and DFN 1.6×1.6 mm package compatibility with high-density USB and industrial PCB layouts.
Technical Context
The RCLAMP0522P.TCT employs 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 due to decreasing RDS(on) under increasing IPP.
It delivers 1120W peak pulse power at 8/20μs, maintains ≤600 nA reverse leakage at 22V, and operates from –40°C to +125°C-enabling robust protection in thermally demanding USB PD, IoT, and industrial load-switch input applications without derating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22 V - matches nominal USB PD bus voltage and avoids false triggering during normal operation. |
| Clamping Voltage | 27.5–28 V at 24–40 A - stays below 30 V threshold to protect 24V-tolerant controllers without margin erosion over temperature. |
| Peak Pulse Current | 40 A (8/20 μs) - meets IEC 61000-4-5 Level 4 surge immunity for industrial equipment interfaces. |
| ESD Withstand | ±30 kV contact/air per IEC 61000-4-2 - exceeds Class 4 system-level ESD requirements for handheld and portable devices. |
| Dynamic Resistance | 20 mΩ - ensures minimal voltage rise under surge, enabling precise clamping independent of current magnitude. |
| Junction Capacitance | 175 pF at 22 V, 1 MHz - compatible with DC/low-speed power and control lines; not intended for high-speed data lanes. |
Pinout & Package
Package: DFN 1.6 mm × 1.6 mm × 0.55 mm, 6-lead, RoHS-compliant, UL 94V-0 molding compound, lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground return for surge current; all three pins must be connected to maximize current sharing and minimize parasitic inductance. |
| 4, 5, 6 | IN | Protected line input; tied together to handle full 40A surge across parallel bond wires and internal FET channels. |
Key Features
| Feature | Design Value |
|---|---|
| FET-based clamping architecture | Delivers flat clamping voltage across 1–40A surge range, eliminating linear VC = VBR + IPP×RDYN drift seen in TVS diodes. |
| Low dynamic resistance | 20 mΩ enables <0.8 V additional drop at 40A, preserving tight voltage margins for 24V-rated downstream ICs. |
| Stable thermal performance | Clamping voltage varies <0.5 V from –40°C to +125°C, removing need for temperature derating in industrial ambient conditions. |
| High-energy surge rating | 1120 W peak pulse power supports repeated exposure to 1.2/50μs + 8/20μs combination waveforms per IEC 61000-4-5. |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting VBus lines in USB-C connectors supporting up to 20V/5A PD negotiation against lightning-induced surges and connector hot-plug transients. IC Role / Device Role / Timing Role: Transient diverting suppressor placed directly at the connector entry point to shunt EOS energy to ground before reaching PD controller or e-fuse. Use Value: Maintains clamping at ≤28 V across full temperature range, preventing damage to 24V-maximum-input PD controllers where conventional TVS would exceed 35 V at 125°C. | Use Scenario: Safeguarding enable and input pins of industrial-grade load switches (e.g., HS2950P) exposed to 42 Ω source impedance surges in remote metering or robotics systems. IC Role / Device Role / Timing Role: Primary front-end surge clamp limiting voltage stress on internal MOSFET gate oxide and drain-source junction during 1 kV/42 Ω transients. Use Value: Prevents latch-up or permanent failure of load switch ICs by holding clamping voltage well below their absolute maximum ratings (typically 30–36 V). |
| IoT Device Power Rail Protection | Notebook/Tablet DC Input Protection |
Use Scenario: Securing 22V-rated auxiliary power inputs in battery-powered edge sensors or gateway modules subject to ESD during field servicing or cable insertion. IC Role / Device Role / Timing Role: Standalone EOS protector on main DC input rail, operating in parallel with upstream fuse and downstream LDO or buck converter. Use Value: Survives ≥30kV contact ESD events without degradation, ensuring long-term reliability in uncontrolled deployment environments with minimal board space overhead. | Use Scenario: Reinforcing DC-in protection on ultraportable notebooks and tablets where space-constrained 22V adapter inputs require high-surge-capability yet low-profile solutions. IC Role / Device Role / Timing Role: Secondary surge suppression stage after bulk TVS, providing precise clamping for sensitive PMIC or battery charge management ICs. Use Value: Enables use of smaller input capacitors and relaxed layout clearances due to predictable, low-inductance clamping behavior and 1.6×1.6 mm footprint. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDS2211P.C | Same electrical specs and package; differs only in reel quantity (3,000 pcs vs. 10,000 pcs for .TCT) and marking code format. | No functional difference; identical placement, soldering, and performance in USB PD or industrial designs. | Select RCLAMP0522P.TCT for standard tape-and-reel volume procurement; TDS2211P.C suits smaller-batch prototyping or distributor fulfillment. |
| uClamp2411ZA.TCT | 24 V working voltage, lower 20 A IPP rating, same DFN-6 package but optimized for CC/SBU lines-not rated for 40 A bus-level surges. | Intended for low-current configuration channel lines, not main VBus; unsuitable for load-switch or high-power rail protection. | Use uClamp2411ZA.TCT only for USB-C CC/SBU protection; RCLAMP0522P.TCT remains required for primary power rail clamping. |
Compared with TDS2211P.C and uClamp2411ZA.TCT, the RCLAMP0522P.TCT offers identical surge performance and package but is designated for high-volume production with standardized tape-and-reel packaging and traceable date coding-making it optimal for OEM manufacturing programs requiring consistent sourcing and lifecycle control.

FAQ
What is the clamping voltage of RCLAMP0522P.TCT at 40A surge current?
The RCLAMP0522P.TCT clamps at 27.6–28 V under 40A (8/20μs) peak pulse current with 2Ω source impedance, per IEC 61000-4-5 combination waveform testing. This value remains stable across –40°C to +125°C, distinguishing it from conventional TVS diodes whose clamping rises with temperature and current.
Is RCLAMP0522P.TCT suitable for protecting USB Type-C superspeed data lines?
No, RCLAMP0522P.TCT is not suitable for USB Type-C superspeed (TX/RX) data lines. Its 175 pF junction capacitance would severely degrade signal integrity. For those lines, Semtech recommends low-capacitance devices like RClamp3371ZC (<0.25 pF); RCLAMP0522P.TCT is intended for VBus, CC, or power-rail protection only.
How does RCLAMP0522P.TCT differ from standard TVS diodes in surge response?
RCLAMP0522P.TCT uses a triggered FET architecture instead of a pn-junction. Its clamping voltage stays nearly constant (27.5–28 V) from 1A to 40A, whereas TVS diodes exhibit linear VC = VBR + IPP×RDYN rise. This eliminates thermal derating and ensures predictable protection margins across operating conditions.
What is the recommended PCB layout for RCLAMP0522P.TCT?
Place RCLAMP0522P.TCT as close as possible to the protected connector. Connect all three IN pins (4,5,6) via a single short, wide trace to the protected line, and tie all three GND pins (1,2,3) directly to a solid ground plane using multiple vias. Avoid thermal pads-energy is dissipated internally, not conducted through the package bottom.
Does RCLAMP0522P.TCT meet RoHS and halogen-free compliance requirements?
Yes, RCLAMP0522P.TCT is Pb-free, halogen-free, and compliant with RoHS and WEEE directives. Its molding compound carries UL 94V-0 flammability rating, and the lead finish is fully lead-free-meeting global environmental and safety standards for industrial and consumer electronics manufacturing.
