Product details
Overview
RCLAMP0561PQTCT 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 PD, USB Type-C, and industrial load switch input protection.
For engineers reviewing the RCLAMP0561PQTCT datasheet, pinout, applications, or equivalent options, this page delivers verified package mapping (DFN-6, 1.6×1.6mm), validated terminal roles (IN/GND), real-world clamping stability data, and direct alternative comparisons for EOS-critical designs.
Technical Context
The RCLAMP0561PQTCT 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 due to decreasing RDS(on) under surge, not fixed dynamic resistance.
It operates over –40°C to +125°C with 22V reverse stand-off voltage, 27.9V typical breakdown, and 20mΩ dynamic resistance (8/20μs). Its 175pF junction capacitance at 22V/1MHz and <600nA leakage support high-speed bus integrity without signal distortion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Stand-Off Voltage | 22 V - defines maximum continuous operating voltage before conduction begins |
| Clamping Voltage | 27.5–28 V at 40A (8/20μs) - ensures protected ICs see consistent overvoltage suppression regardless of surge magnitude |
| Peak Pulse Current | 40 A (8/20μs) - meets IEC 61000-4-5 Level 4 surge immunity for industrial equipment |
| ESD Withstand | ±30 kV contact & air (IEC 61000-4-2) - exceeds Level 4 human-body model requirements for rugged interfaces |
| Junction Capacitance | 175 pF at 22 V, 1 MHz - low enough for 22V power rail protection without degrading transient response |
| Dynamic Resistance | 20 mΩ (8/20μs) - enables flat clamping curve by minimizing IR drop increase under rising current |
| Operating Temperature | –40°C to +125°C - supports deployment in automotive-grade and industrial ambient environments |
Pinout & Package
Package: DFN-6, 1.6 mm × 1.6 mm × 0.55 mm, RoHS-compliant, UL 94V-0 molding compound, lead-free finish, tape-and-reel packaging (3,000 pcs/reel).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground return path for all surge current - must be connected in parallel to maximize current sharing and minimize inductance |
| Pins 4, 5, 6 | IN | Protected line input - all three pins tied together to the same trace for full 40A rating and uniform current distribution |
Key Features
| Feature | Design Value |
|---|---|
| FET-based transient diversion | Replaces traditional TVS with active shunt architecture for flat clamping vs. current/temperature |
| Stable clamping across temperature | 27.5–28 V maintained from –40°C to +125°C - eliminates derating uncertainty in thermal design |
| High-energy surge handling | 1120 W peak pulse power (8/20μs) - supports repeated lightning-surge events without degradation |
| Low dynamic resistance | 20 mΩ enables minimal voltage rise during 40A transients - critical for protecting 22V-rated controllers |
| Compact footprint | 1.6 × 1.6 mm DFN saves >50% board area vs. legacy SO-8 or SOT-23 TVS solutions |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting VBus lines in USB-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: Maintains clamping at ≤28 V across full 40A surge and –40°C to +125°C - prevents damage to 22V-tolerant PD controllers under real-world surges. | Use Scenario: Shielding enable and input pins of industrial-grade e-fuses (e.g., HS2950P) against lightning-induced surges in remote meters and robotics. IC Role / Device Role / Timing Role: Primary EOS protection device upstream of load switch input, absorbing energy before it reaches internal FET gate/drain. Use Value: Limits voltage seen by load switch to 28 V even at 40A - avoids gate oxide rupture or drain-source avalanche failure in high-side switches. |
| IoT Device Power Rail Protection | Storage Device 22V Supply Line Protection |
Use Scenario: Securing 22V auxiliary rails in battery-powered edge sensors exposed to ESD during field servicing or docking. IC Role / Device Role / Timing Role: Standalone EOS protector on main DC input, directly referenced to system ground plane. Use Value: Delivers ±30 kV ESD robustness without adding series impedance - preserves power rail regulation and avoids brownout during fast transients. | Use Scenario: Safeguarding 22V supply inputs to NVMe SSD modules or SAS backplanes subject to hot-plug surges and cable discharge events. IC Role / Device Role / Timing Role: Low-capacitance (175 pF), high-power clamp on primary power entry point before PMIC or LDO. Use Value: Prevents latch-up or overvoltage shutdown in storage controllers by limiting excursion to 28 V at full 40A - ensures uninterrupted data integrity during surge events. |
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-6 package - differs only in reel quantity (3,000 pcs vs. 10,000 pcs) and marking code format | No functional difference; both qualified for USB PD and industrial load switch use per Semtech documentation | Select RCLAMP0561PQTCT for standard distribution channels; TDS2211P.C for volume OEM procurement with alternate packaging |
| uClamp2411ZA | 24 V working voltage, lower 24 A peak pulse rating, smaller 1.0 × 0.6 mm DFN-2 package - optimized for CC/SBU lines, not power rails | Intended for 5 V–24 V low-capacitance signal-line protection (e.g., USB-C CC pins), not 22V power bus clamping | Not interchangeable for power rail use; uClamp2411ZA lacks required 40A surge rating and thermal robustness for VBus protection |
Compared with TDS2211P.C, RCLAMP0561PQTCT offers identical protection performance and package compatibility but differs in distribution packaging and traceability coding; versus uClamp2411ZA, RCLAMP0561PQTCT provides 67% higher surge current capacity and is specifically rated for 22V power-line duty - making it the only valid choice for VBus and load-switch input protection.

FAQ
What is the clamping voltage behavior of RCLAMP0561PQTCT under varying surge currents?
RCLAMP0561PQTCT maintains a tightly bounded clamping voltage of 27.5–28 V across its full 40A peak pulse current range (8/20μs), unlike conventional TVS diodes whose clamping rises linearly with current. This flat response results from its FET-based shunt architecture and sub-20mΩ dynamic resistance, ensuring predictable protection for 22V-rated downstream ICs regardless of surge magnitude. The RCLAMP0561PQTCT datasheet confirms this behavior is guaranteed by design and stable from –40°C to +125°C.
Is RCLAMP0561PQTCT pin-compatible with other Semtech TDS devices like TDS2211P.C?
Yes - RCLAMP0561PQTCT shares identical pin configuration, package dimensions (DFN-6, 1.6×1.6mm), and terminal assignment (Pins 1–3 = GND, Pins 4–6 = IN) with TDS2211P.C. Both devices have identical electrical specifications including 22V stand-off, 27.5–28V clamping, and 40A surge rating. The RCLAMP0561PQTCT differs only in part numbering convention and distribution packaging, not in form, fit, or function.
Can RCLAMP0561PQTCT be used to protect USB-C SuperSpeed differential pairs?
No - RCLAMP0561PQTCT is not suitable for USB-C SuperSpeed (TX/RX) lines due to its 175pF junction capacitance, which would severely degrade signal integrity at multi-Gbps data rates. For those lines, Semtech specifies low-capacitance devices like RClamp3371ZC (<0.25pF). The RCLAMP0561PQTCT is explicitly intended for 22V power rail or single-ended I/O protection, as confirmed in its application diagrams and electrical characterization.
What is the maximum operating temperature range for RCLAMP0561PQTCT?
RCLAMP0561PQTCT is rated for continuous operation from –40°C to +125°C ambient temperature, with junction temperature capability up to +150°C. Its clamping voltage remains stable across this full range - a key differentiator from standard TVS diodes, whose clamping typically increases with temperature. This specification is verified in the RCLAMP0561PQTCT datasheet's Typical Characteristics section, including clamping vs. temperature plots at 40A.
Does RCLAMP0561PQTCT require a thermal pad or heatsink for 40A surge handling?
No - RCLAMP0561PQTCT dissipates surge energy internally via its integrated FET and does not rely on PCB copper area for thermal management. The datasheet explicitly states "no thermal pad is needed" and recommends connecting all GND pins (1–3) and IN pins (4–6) with low-inductance traces and multiple vias to ground - not thermal relief. Its 0.55mm profile and UL 94V-0 molding compound are designed for self-contained surge absorption without external cooling.
