Product details
Overview
RCLAMP04041PW.C from Semtech is a transient diverting suppressor (TDS) designed for high-energy EOS protection of single 22V I/O or power lines, featuring ±30kV IEC 61000-4-2 ESD immunity, 40A peak pulse current (8/20μs), 27.5–28V clamping voltage at 24–40A, 20mΩ dynamic resistance, and 175pF junction capacitance - deployed in USB Type-C PD input protection and industrial load switch inputs.
For engineers reviewing the RCLAMP04041PW.C datasheet, pinout, applications, or equivalent options, key selection criteria include clamping stability across temperature and current, low dynamic resistance for flat VC vs. IPP behavior, DFN-6 package layout constraints, and compatibility with 22V bus systems requiring robust surge immunity per IEC 61000-4-5.
Technical Context
RCLAMP04041PW.C 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 (27.5–28V) across 24–40A and −40°C to +125°C due to decreasing RDS(on) under surge conditions.
The device protects one bidirectional line with 22V working voltage and 27.9V typical breakdown, delivering 1120W peak pulse power. Its functional architecture separates trigger threshold (VBR) from conduction path (low-RDS(on) FET), enabling stable clamping independent of current magnitude or ambient temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage (VRWM) | 22 V - defines maximum continuous DC or RMS operating voltage before leakage rises significantly. |
| Clamping Voltage (VC) | 27.5–28 V at 24–40A (1.2/50μs + 8/20μs combo wave, RS = 2Ω) - ensures protected ICs (e.g., USB PD controllers) remain below damage thresholds during surges. |
| Peak Pulse Current (IPP) | 40 A (8/20μs) - supports compliance with IEC 61000-4-5 Level 4 (±1kV, RS = 42Ω) on unsymmetrical lines. |
| Dynamic Resistance (RDYN) | 20 mΩ - enables flat clamping response; VC variation <0.5V across full 1–40A surge range. |
| Junction Capacitance (CJ) | 175 pF at 22V, 1MHz - suitable for 22V power/data lines where sub-nF loading is acceptable (e.g., VBUS, load switch inputs). |
| ESD Withstand | ±30 kV contact & air (IEC 61000-4-2) - exceeds Level 4 immunity for handheld and connector-facing interfaces. |
| Operating Temperature | −40°C to +125°C - maintains specified clamping and leakage performance across industrial and automotive under-hood environments. |
Pinout & Package
Package: DFN-6 (1.6 mm × 1.6 mm × 0.55 mm), Pb-free, RoHS/WEEE compliant, UL 94V-0 molding compound, tape-and-reel packaging (3000 pcs/reel).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground return for surge current; all three must be connected to maximize current sharing and minimize parasitic inductance. |
| Pins 4, 5, 6 | IN | Protected line input (bidirectional); all three pins are internally paralleled to handle 40A total peak current and reduce trace inductance. |
Key Features
| Feature | Design Value |
|---|---|
| Constant clamping voltage | VC varies ≤0.5V from 24A to 40A and remains stable across −40°C to +125°C - eliminates derating uncertainty in thermal design. |
| Surge-rated FET protection core | Replaces traditional pn-junction TVS with low-RDS(on) MOSFET shunt, reducing energy dissipation in junction and improving reliability under repeated transients. |
| High EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns, 5kHz & 100kHz bursts) - protects against fast repetitive noise in industrial control and motor drive environments. |
| Low dynamic resistance | 20 mΩ measured between 1A and 40A (8/20μs) - ensures minimal voltage rise above trigger threshold during surge conduction. |
| Small-footprint DFN package | 1.6 mm × 1.6 mm area - saves >50% board space versus SO-8 or SOT-23 alternatives while supporting high-current routing via multiple parallel pins. |

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 manufacturer, identical electrical specs and package; RCLAMP04041PW.C is Semtech's alternate marking for TDS2211P.C per official ordering documentation. | Identical use case - no functional or layout change required. | Select RCLAMP04041PW.C when sourcing from distributors listing this part number; verify reel marking "T22" matches date code format. |
| uClamp2411ZA | 24V working voltage, lower 24A IPP, higher 30V clamping, smaller 0.65mm × 0.65mm DFN-2 package. | Targeted at CC/SBU lines in USB-C, not VBUS; insufficient for 40A surge or 22V bus protection. | Use uClamp2411ZA only for low-capacitance, low-current auxiliary lines - not a functional substitute for RCLAMP04041PW.C in power rail roles. |
Compared with TDS2211P.C (identical device) and uClamp2411ZA (lower-power auxiliary protector), RCLAMP04041PW.C delivers verified 40A surge handling and flat 27.5–28V clamping essential for 22V power bus protection - making it uniquely suited for USB PD, load switch, and industrial 22V rail applications where current and thermal stability are critical.

FAQ
What is the exact package type and dimensions of RCLAMP04041PW.C?
RCLAMP04041PW.C uses a DFN-6 package measuring 1.6 mm × 1.6 mm × 0.55 mm with exposed pad-less construction. Pin 1 is marked by a laser dot; pins 1–3 are GND, pins 4–6 are IN. The land pattern requires full copper connection to ground plane via multiple vias for optimal surge current handling - confirmed in Semtech's official outline drawing and PCB layout guidelines for RCLAMP04041PW.C.
Does RCLAMP04041PW.C meet IEC 61000-4-5 Level 4 surge immunity?
Yes, RCLAMP04041PW.C is rated for ±1kV (1.2/50μs voltage waveform, RS = 42Ω, CS = 0.5μF) on unsymmetrical lines and supports 40A peak pulse current (8/20μs), exceeding IEC 61000-4-5 Level 4 requirements. Its 27.5–28V clamping voltage at 40A ensures protected downstream ICs remain within safe operating limits during standardized surge testing - validated in the RCLAMP04041PW.C datasheet absolute maximum and electrical characteristics tables.
How does RCLAMP04041PW.C differ from standard TVS diodes in clamping behavior?
RCLAMP04041PW.C uses a surge-rated FET and precision trigger circuit instead of a pn-junction, resulting in near-constant clamping voltage (27.5–28V) across 1–40A and −40°C to +125°C. Standard TVS diodes exhibit linear VC = VBR + IPP × RDYN rise, causing clamping to increase with current and temperature - a key limitation RCLAMP04041PW.C eliminates per its functional diagram and clamping vs. temperature curves.
Can RCLAMP04041PW.C be used on high-speed data lines like USB SS or PCIe?
No, RCLAMP04041PW.C is not suitable for high-speed data lines due to its 175pF junction capacitance, which would severely degrade signal integrity on superspeed interfaces. It is intended exclusively for 22V power rails, VBUS, load switch inputs, and other low-frequency lines where capacitance is non-critical - as specified in RCLAMP04041PW.C application notes for USB Type-C and industrial equipment.
What is the maximum continuous operating voltage for RCLAMP04041PW.C?
The maximum continuous operating voltage (VRWM) of RCLAMP04041PW.C is 22V DC or RMS, verified in its electrical characteristics table. Operating above this voltage increases reverse leakage current beyond 600nA and risks premature triggering or degradation. This rating aligns with USB PD 20V nominal + 10% tolerance and industrial 22V auxiliary rails - confirmed in the RCLAMP04041PW.C datasheet under "Reverse Stand-Off Voltage".
