Product details
Overview
RCLAMP03354P.C from Semtech is a transient diverting suppressor (TDS) designed for high-energy EOS protection of 22V-rated 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 40A, and ultra-low 20mΩ dynamic resistance - deployed in USB Type-C PD bus protection and industrial load switch input stages.
For engineers reviewing the RCLAMP03354P.C datasheet, pinout, applications, or equivalent options, key selection criteria include clamping stability across temperature and current, low capacitance (175pF @ 22V), DFN 1.6×1.6mm package footprint, and FET-based shunt architecture enabling constant-voltage clamping unlike conventional TVS diodes.
Technical Context
RCLAMP03354P.C employs a surge-rated MOSFET as its primary protection element, activated by a precision trigger circuit that senses overvoltage events and drives the FET into low-RDS(on) conduction. This architecture delivers near-constant clamping voltage independent of peak pulse current magnitude or operating temperature.
It operates with a 22V reverse stand-off voltage (VRWM), 25–27.9V breakdown voltage (VBR), and maintains clamping at 27.5–28V across 24–40A (1.2/50μs + 8/20μs combination waveform, RS = 2Ω), with junction capacitance of 175pF at 22V and 1MHz - optimized for high-speed data/power line protection where voltage margin and signal integrity are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Stand-Off Voltage | 22 V - maximum continuous operating voltage before clamping activation |
| Clamping Voltage | 27.5–28 V at 40A - stable voltage limit during 8/20μs surges, protecting downstream ICs |
| Peak Pulse Current | 40 A (8/20μs) - handles industrial-level lightning/surge transients per IEC 61000-4-5 |
| ESD Withstand | ±30 kV contact & air - exceeds IEC 61000-4-2 Level 4 for robust system-level ESD immunity |
| Dynamic Resistance | 20 mΩ - enables flat clamping curve and minimal voltage rise under increasing surge current |
| Junction Capacitance | 175 pF @ 22V, 1MHz - low enough to avoid signal distortion on 22V power/data buses |
| Package | DFN 1.6 × 1.6 × 0.55 mm, 6-lead - compact footprint for space-constrained USB PD and IoT designs |
Pinout & Package
Package: DFN 1.6 mm × 1.6 mm × 0.55 mm, 6-lead, Pb-free, RoHS-compliant, UL 94V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground return path for surge current; all three pins must be connected to maximize current handling and minimize parasitic inductance |
| 4, 5, 6 | IN | Protected line input - connects directly to 22V bus or power rail; all three pins must be tied together for full 40A rating |
Key Features
| Feature | Design Value |
|---|---|
| FET-based shunt architecture | Enables constant clamping voltage across 24–40A and −40°C to +125°C, unlike voltage-rising TVS diodes |
| Ultra-low dynamic resistance | 20 mΩ ensures minimal IR drop during surge, preserving clamping accuracy and thermal efficiency |
| High-energy surge capability | Rated for 1120 W peak pulse power (8/20μs), supporting industrial IEC 61000-4-5 ±1 kV compliance |
| Low leakage & stable capacitance | 600 nA max reverse leakage at 22V and 175 pF @ 22V enable reliable operation in battery-powered and noise-sensitive systems |
| Compact DFN packaging | 1.6 × 1.6 mm footprint saves >50% board area vs. traditional SO-8 or SOT-23 TVS solutions |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting 20–22V VBus lines in USB-C PD controllers against ESD, lightning surges, and EOS events during hot-plug or fault conditions. IC Role / Device Role / Timing Role: Primary shunt protector placed between connector and PD controller input, clamping transients before they reach sensitive silicon. Use Value: Maintains 27.5–28V clamping across temperature and current - avoids overvoltage damage to PD controllers rated for ≤30V absolute max. |
Use Scenario: Safeguarding input terminals of industrial-grade load switches (e.g., HS2950P) exposed to field-induced surges in remote meters, robotics, or factory automation. IC Role / Device Role / Timing Role: Front-end transient suppressor that limits voltage stress on the load switch's internal FET gate oxide and drain-source junction. Use Value: Prevents premature failure of load switches by holding clamping below their 30–35V damage threshold under 40A surges. |
| IoT Device Power Rail Protection | Storage Device 22V Backup Power Line |
Use Scenario: Securing 22V auxiliary power rails in battery-backed IoT edge nodes subject to ESD from human contact or induced surges in unshielded enclosures. IC Role / Device Role / Timing Role: Single-point protection device on main power entry, absorbing fast-rising ESD (15 ns rise time) and longer surges without degrading long-term reliability. Use Value: Delivers ±30kV contact ESD immunity while adding only 175pF capacitance - no signal integrity impact on associated monitoring or comms circuits. |
Use Scenario: Protecting 22V backup power inputs in NVMe SSDs or enterprise storage controllers during hot-swap or power-fail recovery sequences. IC Role / Device Role / Timing Role: High-reliability transient clamp on non-isolated backup supply lines, ensuring continuity during surge events without latch-up or parametric drift. Use Value: Stable 27.5–28V clamping across −40°C to +125°C enables consistent protection in wide-temperature storage environments. |
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 - direct variant with same marking code structure and reel quantity (3,000/reel) | Identical use case; validated in Semtech's USB-C PD reference design | Select when sourcing from Semtech's official channel with traceable date coding and full compliance documentation |
| uClamp2411ZA | 24V VRWM, lower 24A IPP rating, higher 30V clamping, smaller 0.65×0.65mm 2-pin DFN package | Better suited for CC/SBU lines in USB-C; insufficient for 22V bus due to tighter voltage margin and lower surge rating | Choose only for auxiliary control lines - not a functional replacement for RCLAMP03354P.C on main power rails |
Compared with TDS2211P.C and uClamp2411ZA, RCLAMP03354P.C offers identical surge performance and clamping stability but may differ in tape-and-reel packaging or minor process revisions; uClamp2411ZA provides smaller size and lower cost but sacrifices 16A peak current headroom and clamping precision required for 22V bus protection.

FAQ
What is the exact clamping voltage specification for RCLAMP03354P.C at 40A surge current?
RCLAMP03354P.C clamps at 27.5–28 V under 40A peak pulse current (tp = 1.2/50μs voltage + 8/20μs current combination waveform, RS = 2Ω), as confirmed in the Semtech datasheet Absolute Maximum Ratings and Electrical Characteristics tables. This value remains stable across −40°C to +125°C ambient temperature, distinguishing it from conventional TVS devices.
Is RCLAMP03354P.C pin-compatible with TDS2211P.C?
Yes - RCLAMP03354P.C and TDS2211P.C share identical 6-pin DFN 1.6×1.6mm package dimensions, pin numbering, and terminal assignment (pins 1–3 = GND, pins 4–6 = IN). Both are manufactured by Semtech with matching mechanical drawings and land patterns, enabling direct PCB layout reuse.
Does RCLAMP03354P.C meet IEC 61000-4-5 surge immunity requirements?
Yes - RCLAMP03354P.C is rated for 40A peak pulse current (tp = 8/20μs) and ±1kV (1.2/50μs, RS = 42Ω) on unsymmetrical lines per IEC 61000-4-5, making it suitable for industrial equipment and outdoor IoT deployments requiring Level 3 or Level 4 surge protection compliance.
What is the junction capacitance of RCLAMP03354P.C and how does it affect signal integrity?
RCLAMP03354P.C exhibits 175 pF junction capacitance at 22V reverse bias and 1 MHz, measured per datasheet specifications. This low value minimizes loading on 22V power rails and avoids resonance or attenuation in adjacent high-speed traces - critical for USB-C PD bus integrity where voltage regulation stability is essential.
Can RCLAMP03354P.C be used to protect USB-C SuperSpeed differential pairs?
No - RCLAMP03354P.C is not intended for USB-C SuperSpeed (TX/RX) lanes. Its 175 pF capacitance would severely degrade signal integrity on high-speed differential lines. For those, Semtech specifies low-capacitance devices like RClamp3371ZC (<0.25 pF); RCLAMP03354P.C is strictly for VBus, CC, SBU, or power-line protection.
