Product details
Overview
RCLAMP0506T.TCT 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), and stable 27.5–28V clamping across temperature and current range - deployed in USB Type-C PD, load switch input protection, and industrial IoT interfaces.
For engineers reviewing the RCLAMP0506T.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 1.6×1.6mm 6-lead package compatibility with high-density PCB layouts.
Technical Context
The RCLAMP0506T.TCT uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit that senses overvoltage events and rapidly shunts transient current to ground. Unlike conventional TVS diodes, its clamping voltage remains nearly constant due to decreasing RDS(on) under increasing surge current.
It operates across –40°C to +125°C with reverse stand-off voltage of 22V, breakdown voltage of 25–27.9V, and guaranteed clamping at 27.5–28V for 24A and 40A pulses (1.2/50μs voltage + 8/20μs current combination waveform, RS = 2Ω). Its 175 pF junction capacitance at 22V/1MHz supports robust protection without signal integrity compromise on moderate-speed buses.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC or RMS operating voltage on protected line without leakage or conduction. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs + 1.2/50μs combo wave) - ensures downstream 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 for 22V systems. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds automotive and industrial ESD immunity standards for connector-facing protection. |
| Dynamic Resistance | 20 mΩ - enables flat clamping response and minimizes voltage overshoot during fast-rising transients. |
| Junction Capacitance | 175 pF at 22V/1MHz - suitable for USB 2.0, power bus, and industrial control lines where <200 pF is acceptable. |
Pinout & Package
Package: DFN 1.6 mm × 1.6 mm × 0.55 mm, 6-lead, Pb-free, RoHS/WEEE compliant, UL 94V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground return path for surge current; all three must be connected to minimize inductance and maximize 40A capability. |
| Pins 4, 5, 6 | IN | Protected line input (e.g., VBUS or power rail); parallel connection ensures uniform current sharing and thermal distribution. |
Key Features
| Feature | Design Value |
|---|---|
| FET-based transient shunting | Replaces traditional TVS diodes with active clamping: near-constant VC across 1–40A and –40°C to +125°C. |
| Low dynamic resistance | 20 mΩ enables sub-1V voltage rise per 10A surge - critical for protecting 22V-rated load switches and PD controllers. |
| High-energy surge rating | 1120W peak pulse power (8/20μs) supports repeated lightning-induced surges in industrial equipment and metering. |
| Ultra-low leakage | ≤600 nA at 22V - avoids system-level power drain or false triggering in always-on IoT and remote sensor applications. |
Applications
| USB Type-C Power Delivery Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting VBUS lines in USB Type-C connectors supporting up to 20V PD, exposed to ESD and cable-borne surges. IC Role / Device Role / Timing Role: Primary EOS/ESD clamp placed between connector and PD controller or load switch. Use Value: Maintains 27.5–28V clamping across temperature - prevents overvoltage damage to 22V-tolerant PD ICs where standard TVS would exceed 35V at 125°C. |
Use Scenario: Safeguarding input pins of industrial-grade load switches (e.g., HS2950P) against lightning-induced surges in remote meters and robotics. IC Role / Device Role / Timing Role: Front-end transient suppressor limiting voltage seen by internal FET gate oxide and drain-source junction. Use Value: Clamps at ≤28V even at 40A/125°C - keeps stress below 80% of typical 35V load switch absolute max ratings, extending reliability. |
| IoT Edge Node Power Bus Protection | Storage Device 22V Rail Protection |
Use Scenario: Securing 22V auxiliary rails in battery-backed smart sensors and gateway modules subjected to field ESD and induced transients. IC Role / Device Role / Timing Role: Standalone shunt protector on main power input, coordinated with upstream e-fuse or PMIC. Use Value: 175 pF capacitance and 600 nA leakage avoid compromising sleep-mode current or signal integrity on shared power domains. |
Use Scenario: Protecting 22V supply inputs of NVMe SSD enclosures and enterprise storage backplanes against hot-plug and ESD events. IC Role / Device Role / Timing Role: High-reliability clamping device placed at board edge before DC-DC regulation stages. Use Value: 40A surge rating and 1120W peak power withstand ensure survival of multiple IEC 61000-4-5 Level 4 surges without degradation. |
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 die, identical electrical specs, identical DFN 1.6×1.6mm package; differs only in tape-and-reel packaging (3,000 pcs/reel vs. RCLAMP0506T.TCT's unspecified quantity). | Direct drop-in replacement in production; same layout, same thermal and electrical behavior. | Select TDS2211P.C when sourcing via Semtech's standard distribution channel with full traceability and reel logistics. |
| uClamp2411ZA | 24V working voltage, lower 24A IPP rating, higher 30V clamping, smaller 1.0×1.0mm 2-pin SOD-323 package - not pin-compatible. | Targeted at CC/SBU lines in USB-C, not VBUS/power rail; unsuitable for 40A surge or 22V bus protection. | Use uClamp2411ZA only for low-capacitance, low-current auxiliary signal lines - not as substitute for RCLAMP0506T.TCT in power rail roles. |
Compared with TDS2211P.C, RCLAMP0506T.TCT offers identical protection performance and footprint but may differ in reel packaging and date-code marking; versus uClamp2411ZA, it delivers 67% higher surge current handling and 2.5× lower clamping voltage at rated current - making it the sole viable option for 22V power rail EOS hardening.

FAQ
What is the maximum continuous operating voltage for RCLAMP0506T.TCT?
The RCLAMP0506T.TCT has a reverse stand-off voltage (VRWM) of 22V, meaning it can continuously block up to 22V DC or RMS without significant leakage or conduction. This makes it suitable for 22V power rails such as USB PD VBUS and industrial 24V nominal systems operating within tolerance bands. Exceeding 22V risks premature conduction and accelerated wear.
Does RCLAMP0506T.TCT meet IEC 61000-4-5 surge immunity standards?
Yes, the RCLAMP0506T.TCT is rated for 40A peak pulse current using the 8/20μs waveform and supports ±1kV combination-wave surge testing (1.2/50μs voltage + 8/20μs current, RS = 42Ω), satisfying IEC 61000-4-5 Level 4 for industrial environments. Its 1120W peak pulse power rating confirms compliance under worst-case energy conditions.
How does RCLAMP0506T.TCT differ from standard TVS diodes in clamping behavior?
Unlike standard TVS diodes whose clamping voltage rises linearly with surge current (VC = VBR + IPP × RDYN), the RCLAMP0506T.TCT uses an active FET-based architecture that maintains clamping voltage at 27.5–28V across its full 1–40A range and from –40°C to +125°C - delivering predictable, temperature-stable protection unattainable with passive TVS devices.
What is the junction capacitance of RCLAMP0506T.TCT, and where is it appropriate to use?
The RCLAMP0506T.TCT exhibits 175 pF junction capacitance at 22V and 1MHz, measured across IN-to-GND. This value is well-suited for USB 2.0, industrial control buses, and 22V power rails where signal bandwidth is below ~50 MHz. It is not recommended for USB 3.x or PCIe lanes requiring <0.3 pF - those demand ultra-low-capacitance devices like RClamp3371ZC.
Can RCLAMP0506T.TCT be used in parallel with other protectors for higher surge handling?
No - the RCLAMP0506T.TCT is not designed for parallel operation. Its internal trigger circuit and FET activation are calibrated for single-device performance. Parallel placement risks uneven current sharing, thermal runaway, and failure to activate synchronously. For higher surge ratings, select a higher-IPP-rated device (e.g., TDS2411P for 24V/60A) or implement staged protection with upstream current limiting.
