Product details
Overview
RCLAMP03391PW.C from Semtech is a transient diverting suppressor (TDS) designed for high-energy EOS protection of 22V-rated power or I/O lines, featuring ±30kV IEC 61000-4-2 ESD immunity, 40A peak pulse current (8/20μs), 27.5–28V clamping voltage at 40A, and 175pF junction capacitance - deployed in USB Type-C PD input protection and industrial load switch inputs.
For engineers reviewing the RCLAMP03391PW.C datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, DFN-6 package layout guidance, temperature-stable clamping behavior, and direct alternatives for 22V bus protection in high-reliability USB PD and IoT systems.
Technical Context
RCLAMP03391PW.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 threshold. Unlike conventional TVS diodes, its clamping voltage remains nearly constant across 24–40A pulse range due to decreasing RDS(on) under surge conditions.
The device operates over –40°C to +125°C, maintains stable 27.5–28V clamping up to 125°C, and exhibits <20mΩ dynamic resistance (8/20μs). Its 175pF capacitance at 22V/1MHz and 130–600nA leakage support high-speed interface protection without signal integrity compromise.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - matches nominal USB PD bus voltage and protects downstream 22V-tolerant controllers without derating. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs + 1.2/50μs combo wave) - stays below 30V damage threshold of common USB PD ICs across full temp range. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds industrial and consumer ESD immunity requirements for exposed ports. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 3 surge immunity for industrial equipment and USB PD power inputs. |
| Junction Capacitance | 175pF at 22V/1MHz - low enough for DC power rail protection; not intended for high-speed data lines (use RClamp3371ZC instead). |
| Dynamic Resistance | 20mΩ (8/20μs) - enables flat clamping curve and minimizes voltage overshoot during fast-rising transients. |
Pinout & Package
Package: DFN-6, 1.6mm × 1.6mm × 0.55mm, Pb-free/RoHS-compliant, UL 94V-0 molding compound, with thermal pad-less construction optimized for PCB-level surge dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground return path for surge current; all three must be connected with low-inductance vias to maximize 40A capability. |
| Pins 4, 5, 6 | IN | Protected line input (e.g., VBUS or load switch input); parallel connection ensures uniform current sharing and optimal clamping performance. |
Key Features
| Feature | Design Value |
|---|---|
| FET-based transient diversion | Replaces traditional TVS with active shunt architecture, delivering flat clamping vs. current and temperature - critical for 22V PD systems operating at 125°C. |
| Stable clamping over temperature | 27.5–28V clamping maintained from –40°C to +125°C - eliminates design margin inflation required with conventional TVS diodes. |
| High-energy surge handling | 1120W peak pulse power (8/20μs) supports repeated lightning-surge events in industrial and outdoor IoT deployments. |
| Low dynamic resistance | 20mΩ enables sub-1V overshoot during 40A transients - preserves voltage headroom for sensitive load switches like HS2950P. |
Applications
| USB Type-C Power Delivery Input Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting VBUS lines in USB-C receptacles supporting up to 20V/5A PD negotiation, exposed to ESD and surge in docking stations and portable chargers. IC Role / Device Role / Timing Role: Primary EOS shunt protector placed between connector and PD controller or load switch, responding within nanoseconds to divert >40A surges. Use Value: Maintains 27.5–28V clamping at 125°C - prevents latch-up or gate oxide damage in USB PD controllers rated for ≤30V absolute max. |
Use Scenario: Safeguarding enable and input pins of industrial-grade load switches (e.g., HS2950P) in remote meters, PLC I/O modules, and robotic power rails. IC Role / Device Role / Timing Role: Front-end transient clamp upstream of the load switch FET, limiting drain-source voltage during lightning-induced surges. Use Value: Keeps clamping voltage below 30V - avoids destruction of internal MOSFETs with 30V VDSS ratings while sustaining 40A surge compliance. |
| IoT Edge Device Power Bus Protection | USB-C Docking Station VBUS Line Protection |
Use Scenario: Securing 22V-capable power inputs in battery-powered IoT gateways, smart sensors, and cellular routers deployed in uncontrolled environments. IC Role / Device Role / Timing Role: Single-component solution for combined ESD, EFT, and surge immunity per IEC 61000-4-2/4-4/4-5 on main power rail. Use Value: Eliminates need for multi-stage TVS+MOV designs - reduces BOM count and PCB area by 40% versus legacy approaches. |
Use Scenario: Protecting host-side VBUS lines in multi-port USB-C docks handling simultaneous PD negotiation, video, and data. IC Role / Device Role / Timing Role: High-power rail clamp co-located with connector to minimize trace inductance and prevent coupling into adjacent DP/DM lanes. Use Value: 1.6mm × 1.6mm footprint enables placement directly at connector - achieves <1.5nH ground loop inductance for sub-100ps ESD response. |
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 and DFN-6 package; RCLAMP03391PW.C is Semtech's alternate marking for TDS2211P.C per official ordering documentation. | Direct second-source marking - functionally identical, same tape-and-reel packaging (3,000 pcs/reel, 7″). | Select RCLAMP03391PW.C when sourcing through distribution channels using that part number; no design or layout changes required. |
| uClamp2411ZA | 24V working voltage, lower 24A IPP rating, higher 30V clamping, smaller 1.0mm × 0.6mm SOD-523 package. | Suitable only for CC/SBU lines or low-power auxiliary rails - insufficient for 40A VBUS protection. | Use uClamp2411ZA only for secondary signal-line protection; not a replacement for RCLAMP03391PW.C in main power rail roles. |
Compared with TDS2211P.C and uClamp2411ZA, RCLAMP03391PW.C delivers identical 40A/28V performance in the same DFN-6 footprint but offers broader distribution availability, while uClamp2411ZA serves distinct low-capacitance, low-current roles and cannot handle VBUS-level surge energy.

FAQ
What is the exact package type and dimensions of RCLAMP03391PW.C?
RCLAMP03391PW.C uses a DFN-6 package measuring 1.6mm × 1.6mm × 0.55mm with exposed pad-less construction. Pins 1–3 are GND; pins 4–6 are IN. The land pattern follows Semtech's recommended layout with multiple vias to ground plane - critical for achieving full 40A surge rating. This package is identical to that used for TDS2211P.C.
Does RCLAMP03391PW.C meet IEC 61000-4-5 surge immunity standards?
Yes, RCLAMP03391PW.C is rated for 40A peak pulse current under IEC 61000-4-5 (8/20μs waveform) and supports ±1kV combination-wave testing (1.2/50μs voltage + 8/20μs current, RS = 42Ω). Its 27.5–28V clamping ensures protected circuits remain within safe operating limits during industrial-grade surge events.
How does RCLAMP03391PW.C differ from standard TVS diodes in clamping behavior?
RCLAMP03391PW.C uses a surge-rated FET and precision trigger circuit instead of a pn-junction. This yields near-constant 27.5–28V clamping from 24A to 40A and across –40°C to +125°C - unlike TVS diodes whose clamping rises linearly with current and temperature. That stability eliminates over-design margin in USB PD and industrial power systems.
Can RCLAMP03391PW.C be used on high-speed data lines like USB SS or DisplayPort?
No, RCLAMP03391PW.C is not suitable for high-speed data lines. Its 175pF junction capacitance would severely degrade signal integrity. For USB SuperSpeed, DP, or HDMI lanes, Semtech specifies low-capacitance devices like RClamp3371ZC (<0.25pF). RCLAMP03391PW.C is strictly intended for DC power or low-frequency control lines.
Is RCLAMP03391PW.C pin-compatible with other Semtech TDS devices?
RCLAMP03391PW.C shares the same DFN-6 pinout (GND on pins 1–3, IN on pins 4–6) with TDS2211P.C and is functionally identical. However, it is not pin-compatible with lower-voltage TDS variants (e.g., TDS1211P) or different package types - each requires verification against its specific datasheet pin configuration.
