Product details
Overview
RCLAMP3374N.TRT from Semtech is a transient diverting suppressor (TDS) designed for high-energy EOS protection of 22V-rated power or data lines, featuring ±30kV IEC 61000-4-2 ESD immunity, 40A peak pulse current (8/20μs), 27.5–28V clamping voltage at 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 RCLAMP3374N.TRT 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
RCLAMP3374N.TRT 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) from 24A to 40A due to decreasing RDS(on) under surge conditions.
The device operates over –40°C to +125°C, maintains stable clamping across temperature, and delivers 1120W peak pulse power. Its 175pF capacitance at 22V/1MHz and 130–600nA leakage at VRWM make it suitable for medium-speed power-line protection where low capacitance is not critical but low clamping variation is essential.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC or RMS operating voltage on protected line without leakage degradation. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs + 1.2/50μs combo wave, RS = 2Ω) - ensures downstream 24V-rated ICs (e.g., USB PD controllers) remain below damage threshold during surge. |
| Peak Pulse Current | 40A (tp = 8/20μs) - supports compliance with IEC 61000-4-5 Level 4 (±1kV, RS = 42Ω) on unsymmetrical lines. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds industrial and consumer ESD immunity requirements for connector-facing protection. |
| Dynamic Resistance | 20mΩ - enables flat clamping response; VC rise <0.1V from 1A to 40A, minimizing voltage overshoot under varying surge magnitude. |
| Junction Capacitance | 175pF at 22V, 1MHz - appropriate for power/bus lines (not high-speed data), avoiding signal integrity issues in ≤10MHz applications. |
Pinout & Package
Package: DFN-6 (1.6mm × 1.6mm × 0.55mm), RoHS-compliant, halogen-free, UL 94V-0 molding compound, tape-and-reel packaging.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground return 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 in USB-C); parallel connection required to distribute surge current and reduce trace inductance. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies <0.5V from 24A to 40A - eliminates need for overrating IPP to meet VC budget, unlike TVS diodes. |
| Temperature-stable protection | VC remains 27.5–28V from –40°C to +125°C - enables reliable operation in industrial enclosures without derating. |
| Low dynamic resistance | 20mΩ measured between 1A–40A - reduces IR drop during surge, preserving margin between VC and downstream IC absolute max ratings. |
| High-energy surge handling | 1120W peak pulse power (8/20μs) - sustains multiple IEC 61000-4-5 surges without parametric shift or failure. |
Applications
| USB Type-C Power Delivery Input Protection | Industrial Load Switch Input Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDS2211P | Identical electrical specs, same DFN-6 package, identical pinout (Pins 1–3 GND, Pins 4–6 IN), same Semtech TDS architecture. | Direct second-source variant; marked "T22" + date code instead of "RCLAMP3374N.TRT", functionally interchangeable in all layouts. | Select TDS2211P when dual-sourcing or qualifying alternate part numbers with identical qualification history and test reports. |
| uClamp2411ZA | 24V working voltage, lower 24A IPP rating, higher 30V clamping at 24A, smaller 1.0×1.0mm DFN-2 package, optimized for CC/SBU lines. | Designed for low-current control lines (not power buses); insufficient for 40A VBUS protection; used alongside RCLAMP3374N.TRT in full USB-C solutions. | Use uClamp2411ZA only for auxiliary signal lines; do not substitute for RCLAMP3374N.TRT in power-line roles due to IPP and VC mismatch. |
Compared with TDS2211P, RCLAMP3374N.TRT offers identical performance and fit but differs in marking and reel packaging - enabling seamless drop-in replacement. Versus uClamp2411ZA, RCLAMP3374N.TRT provides 67% higher surge current rating and 2.5V lower clamping, making it suitable for primary power rail protection where uClamp2411ZA is limited to control signals.

FAQ
What is the exact clamping voltage specification for RCLAMP3374N.TRT at 40A surge current?
The clamping voltage of RCLAMP3374N.TRT is guaranteed at 27.5–28V under IEC 61000-4-5 combination waveform conditions (1.2/50μs voltage + 8/20μs current, RS = 2Ω) at 40A peak pulse current. This value is confirmed in the official Semtech datasheet Rev 2.5 and remains stable across –40°C to +125°C ambient temperature.
Is RCLAMP3374N.TRT pin-compatible with TDS2211P?
Yes, RCLAMP3374N.TRT is pin-compatible with TDS2211P: both use the same DFN-6 (1.6mm × 1.6mm) package with identical pin 1 location, identical terminal assignment (Pins 1–3 = GND, Pins 4–6 = IN), and identical land pattern. No PCB changes are required when substituting RCLAMP3374N.TRT for TDS2211P.
Can RCLAMP3374N.TRT be used to protect high-speed data lines like USB SS or PCIe?
No, RCLAMP3374N.TRT is not suitable for high-speed data lines. Its 175pF junction capacitance would severely degrade signal integrity above ~10MHz. For USB SuperSpeed or PCIe lanes, Semtech recommends low-capacitance devices such as RClamp3371ZC (<0.25pF), which are specifically designed for signal-line protection without bandwidth loss.
What is the maximum operating temperature range for RCLAMP3374N.TRT?
RCLAMP3374N.TRT is rated for continuous operation from –40°C to +125°C ambient temperature. Its clamping voltage, leakage current, and dynamic resistance remain within specification across this full range, as verified in the Typical Characteristics section of the Semtech datasheet Rev 2.5.
Does RCLAMP3374N.TRT require a thermal pad or heatsink for 40A surge handling?
No, RCLAMP3374N.TRT does not require a thermal pad or heatsink. The device dissipates surge energy in the FET channel during transient events, not continuously. Layout guidelines emphasize low-inductance grounding (multiple vias to solid ground plane) rather than thermal mass - parasitic inductance reduction is more critical than thermal conduction for maintaining clamping performance.
