Product details
Overview
RCLAMP03354P.A 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), 27.6V clamping at 40A, 20mΩ dynamic resistance, and 175pF junction capacitance - deployed in USB PD, USB Type-C VBus, and industrial load switch input protection.
For engineers reviewing the RCLAMP03354P.A datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability across temperature and current, low dynamic resistance for flat VC response, DFN-6 package layout compatibility, and compliance with IEC 61000-4-2/4-4/4-5 surge standards.
Technical Context
RCLAMP03354P.A 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 achieves 1120W peak pulse power handling. Its 175pF capacitance at 22V and 1MHz enables use on moderate-speed power rails without signal integrity compromise.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC bus voltage it can protect without leakage or degradation. |
| Clamping Voltage | 27.6V at 40A (8/20μs) - ensures protected ICs (e.g., USB PD controllers) remain below damage threshold during worst-case surges. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - meets highest-level system-level ESD immunity requirements for end-equipment certification. |
| Peak Pulse Current | 40A (8/20μs) - supports robust protection against lightning-induced surges per IEC 61000-4-5 Level 4. |
| Dynamic Resistance | 20mΩ - enables near-constant clamping voltage across full rated current range, unlike TVS diodes with linear VC = VBR + IPP×RDYN. |
| Junction Capacitance | 175pF at 22V, 1MHz - suitable for VBus and power-line protection where low-to-moderate bandwidth is acceptable. |
Pinout & Package
Package: DFN 1.6mm × 1.6mm × 0.55mm, 6-lead, Pb-free, RoHS/WEEE compliant, UL 94V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground connection points - all three must be soldered to maximize surge current path area and minimize parasitic inductance. |
| 4, 5, 6 | IN | Protected line input - connected directly to VBus or power rail; all three pins are internally tied and must be routed together for full 40A rating. |
Key Features
| Feature | Design Value |
|---|---|
| FET-based transient diversion | Replaces traditional TVS with active shunt architecture, delivering flat clamping voltage independent of surge amplitude. |
| Temperature-stable clamping | Clamping voltage varies <±0.5V from −40°C to +125°C - eliminates derating concerns in industrial thermal environments. |
| High-energy surge handling | 1120W peak pulse power (8/20μs) - sustains repeated 40A transients without parametric shift or failure. |
| Low dynamic resistance | 20mΩ measured between 1A–40A - ensures minimal IR drop during conduction, preserving clamping accuracy. |
| Compact DFN-6 footprint | 1.6mm × 1.6mm area - saves >50% board space vs. legacy SO-8 or SOT-23 TVS solutions with comparable ratings. |
Applications
| USB Type-C Power Delivery | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting 20V–22V VBus lines in USB-C receptacles exposed to ESD, hot-plug transients, and system-level surges. IC Role / Device Role / Timing Role: Primary EOS protection device placed at connector entry point, shunting surge energy to ground before reaching PD controller or e-fuse. Use Value: Maintains 27.6V clamping at 40A and 125°C - prevents overvoltage damage to USB PD controllers rated ≤24V absolute max. |
Use Scenario: Safeguarding input terminals of industrial-grade load switches (e.g., HS2950P) in remote meters, robotics, and IoT edge nodes. IC Role / Device Role / Timing Role: Front-end surge clamp limiting voltage seen by internal FET gate oxide and drain-source junction during lightning or inductive switching events. Use Value: Clamps below 28V across full temperature and current range - avoids gate oxide rupture and drain avalanche failure in sensitive load switches. |
| Storage Device Power Rails | Notebook/Tablet VBus Protection |
Use Scenario: Securing 12V–22V power inputs to SSDs, NVMe modules, and external HDD enclosures subjected to docking station surges and ESD. IC Role / Device Role / Timing Role: Standalone transient suppressor on main power rail, operating in parallel with bulk capacitance and upstream regulators. Use Value: 175pF capacitance avoids resonance issues with typical 10–100μF bulk caps; 40A rating handles multi-event surge stress in portable storage. |
Use Scenario: VBus line protection in ultrabooks and tablets supporting USB-C charging up to 20V/5A, requiring compact, high-reliability surge suppression. IC Role / Device Role / Timing Role: First-line defense at USB-C port PCB entry, minimizing trace length to reduce inductive overshoot during fast ESD events. Use Value: 1.6mm × 1.6mm DFN-6 footprint fits tight space constraints near connectors while delivering certified ±30kV ESD immunity. |
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 silicon die, identical electrical specs, but marked with "T22" code and shipped in 7″ tape-and-reel (3,000 pcs); RCLAMP03354P.A uses different marking and packaging. | No functional difference - both qualified for USB PD and industrial VBus; TDS2211P.C is Semtech's standard orderable variant. | Select RCLAMP03354P.A for Aetrix inventory continuity; choose TDS2211P.C for direct Semtech sourcing with full traceability. |
| uClamp2411ZA | 24V working voltage, lower 24A IPP rating, higher 30V clamping at 24A, and smaller 0.65pF capacitance - optimized for CC/SBU lines, not power rails. | Designed for low-capacitance signal-line protection (CC, SBU), not 22V power rail clamping; unsuitable for VBus due to lower surge rating and higher VC. | Use uClamp2411ZA only for auxiliary USB-C signal lines; RCLAMP03354P.A remains mandatory for VBus and load-switch input protection. |
Compared with TDS2211P.C, RCLAMP03354P.A offers identical protection performance but distinct packaging and marking for channel-specific logistics; versus uClamp2411ZA, it delivers 67% higher peak current capability and 2.4V lower clamping - making it the sole viable option for 22V power-rail EOS suppression.

FAQ
What is the maximum continuous operating voltage for RCLAMP03354P.A?
RCLAMP03354P.A has a reverse stand-off voltage (VRWM) of 22V, meaning it reliably blocks up to 22V DC without significant leakage current. This makes it suitable for protecting 20V USB PD VBus lines and other 22V-rated power rails where sustained voltage exposure occurs.
How does RCLAMP03354P.A differ from standard TVS diodes in clamping behavior?
RCLAMP03354P.A uses a surge-rated FET and precision trigger circuit instead of a pn-junction, resulting in near-constant clamping voltage (27.5–28V) from 1A to 40A. Standard TVS diodes exhibit linear VC rise with current (VC = VBR + IPP × RDYN), causing higher clamping at elevated surge levels - a key limitation RCLAMP03354P.A eliminates.
Is RCLAMP03354P.A compatible with automated SMT assembly processes?
Yes, RCLAMP03354P.A is supplied in a standard DFN-6 package (1.6mm × 1.6mm × 0.55mm) with lead-free, RoHS-compliant terminations and UL 94V-0 molding compound. It supports reflow profiles per J-STD-020 and is qualified for high-volume pick-and-place assembly with standard DFN fiducials and stencil apertures.
What is the junction capacitance of RCLAMP03354P.A, and how does it affect circuit design?
RCLAMP03354P.A exhibits 175pF junction capacitance at 22V and 1MHz. This value is appropriate for power-line and moderate-speed data-line protection but not for high-speed differential pairs (e.g., USB SS, PCIe). Designers should place it on VBus or load-switch inputs - not on DP/DM or TX/RX traces - to avoid signal integrity degradation.
Can RCLAMP03354P.A be used in automotive applications?
RCLAMP03354P.A is specified for −40°C to +125°C operation and meets IEC 61000-4-2/4-4/4-5, but it is not AEC-Q200 qualified. For automotive infotainment or body-control modules requiring automotive qualification, Semtech's automotive-grade TDS variants (e.g., TDS2211P-AQ) must be selected instead of RCLAMP03354P.A.
