Product details
Overview
RCLAMP03354P.N 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 ultra-low 20mΩ dynamic resistance - deployed in USB PD, USB Type-C VBus, and industrial load switch input protection.
For engineers reviewing the RCLAMP03354P.N datasheet, pinout, applications, or equivalent options, key selection criteria include clamping stability across temperature (-40°C to +125°C), constant VC under 24–40A surge, low 175pF junction capacitance at 22V, and DFN 1.6×1.6mm 6-lead package compatibility with high-density PCB layouts.
Technical Context
RCLAMP03354P.N 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 due to decreasing RDS(on) under increasing current.
The device operates with reverse stand-off voltage of 22V, breakdown voltage of 25–27.9V at 1mA, and maintains stable clamping (27.5–28V) across 24–40A IPP and -40°C to +125°C ambient - enabled by solid-state architecture and low 20mΩ dynamic resistance measured between 1A and 40A.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC operating voltage on protected line without leakage or conduction. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs + 1.2/50μs combo wave, RS = 2Ω) - ensures downstream ICs (e.g., USB PD controllers) remain below damage threshold during surge. |
| ESD Withstand | ±30kV contact & air per IEC 61000-4-2 - provides robust system-level ESD immunity without degradation after repeated strikes. |
| Peak Pulse Current | 40A (tp = 8/20μs) - meets IEC 61000-4-5 Level 4 surge requirements for industrial and USB PD applications. |
| Junction Capacitance | 175pF at VR = 22V, f = 1MHz - low enough to avoid signal integrity issues on 22V power rails while enabling compact layout. |
| Dynamic Resistance | 20mΩ - enables flat clamping curve and minimizes voltage rise under high-current transients. |
| Operating Temp | -40°C to +125°C - supports operation in harsh environments including industrial equipment and automotive-adjacent systems. |
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 for surge return path; all three pins must be connected to maximize current handling and minimize parasitic inductance. |
| 4, 5, 6 | IN | Protected line input (e.g., USB PD VBus); parallel connection of all three pins ensures uniform current sharing and optimal 40A surge capability. |
Key Features
| Feature | Design Value |
|---|---|
| Constant clamping voltage | 27.5–28V across full 24–40A IPP range and -40°C to +125°C - eliminates design margin uncertainty vs. TVS diodes whose VC rises with current and temperature. |
| FET-based shunt architecture | Surge-rated MOSFET triggered by precision circuit - delivers lower dynamic resistance (20mΩ) and higher energy handling than PN-junction TVS devices. |
| Low junction capacitance | 175pF at 22V - preserves signal integrity on high-voltage power rails without requiring additional filtering or layout compromises. |
| High EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns, 100kHz & 5kHz) - protects against repetitive fast transients common in industrial motor drives and switching power supplies. |
Applications
| USB Type-C Power Delivery | Industrial Load Switch Input Protection |
|---|---|
|
Use Scenario: Protecting 20–22V VBus lines in USB-C receptacles exposed to lightning-induced surges and connector hot-plug ESD. IC Role / Device Role / Timing Role: Primary EOS suppressor placed directly at connector, clamping transients before they reach USB PD controller or load switch. Use Value: Maintains 27.5–28V clamping at 40A and 125°C - prevents overvoltage damage to PD controllers rated for ≤30V absolute max, unlike TVS diodes that exceed 35V at elevated temperature. |
Use Scenario: Safeguarding input terminals of industrial-grade load switches (e.g., HS2950P) in remote meters, robotics, and IoT gateways. IC Role / Device Role / Timing Role: Front-end transient diverter that limits voltage seen by internal FET of load switch during 1.2/50μs surges. Use Value: Prevents gate oxide rupture and drain-source avalanche failure in load switches by holding clamping voltage well below their 30–35V breakdown limit under 40A surge conditions. |
| Storage Device Power Rails | Notebook/Tablet 22V System Buses |
|
Use Scenario: Securing 19–22V auxiliary power inputs in NVMe SSD enclosures and external storage docks subjected to ESD and conducted surges. IC Role / Device Role / Timing Role: Single-device solution replacing multi-stage TVS+MOV networks, reducing BOM count and board space. Use Value: Delivers 1120W peak pulse power handling in 1.6×1.6mm footprint - enables compact, thermally efficient protection without thermal pads or heatsinking. |
Use Scenario: Protecting 20V system rails in ultrabooks and tablets where space constraints preclude larger TVS arrays. IC Role / Device Role / Timing Role: High-density, low-profile suppressor mounted adjacent to USB-C port or battery charging IC. Use Value: 175pF capacitance avoids resonance or ringing on 22V rails; RoHS-compliant DFN package supports lead-free reflow and automated assembly. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDS2211P | Same manufacturer, identical electrical specs and package - direct functional match with confirmed 22V working voltage, 40A rating, and DFN 1.6×1.6mm footprint. | Identical use case coverage: USB PD, load switch input, industrial 22V rails. | Select when sourcing from Semtech's official TDS family with documented production status and full lifecycle support. |
| SMAJ22A | Standard unidirectional TVS diode; 22V VRWM, 35.2V VC @ 22.5A; higher clamping, no temperature stability, 6.5pF typical capacitance. | Limited to lower-energy transients; unsuitable for 40A surges or high-temp industrial environments where clamping drift exceeds safe margins. | Consider only for cost-sensitive, low-surge-risk applications where 35V+ clamping is acceptable and thermal derating is managed externally. |
Compared with TDS2211P and SMAJ22A, RCLAMP03354P.N offers identical performance to TDS2211P in clamping stability, surge rating, and package - but differs in marking and reel packaging (RCLAMP03354P.N is Semtech's commercial distribution variant). SMAJ22A requires significant design margin due to rising VC with temperature and current.

FAQ
What is the exact working voltage and maximum clamping voltage of RCLAMP03354P.N?
RCLAMP03354P.N has a reverse stand-off voltage (VRWM) of 22V and clamps at 27.5–28V when subjected to 40A peak pulse current (8/20μs + 1.2/50μs combination waveform, RS = 2Ω). This clamping voltage remains stable across -40°C to +125°C and the full 24–40A surge range - a key differentiator from standard TVS diodes.
Is RCLAMP03354P.N pin-compatible with TDS2211P?
Yes, RCLAMP03354P.N is functionally and physically identical to TDS2211P: both use the same DFN 1.6mm × 1.6mm × 0.55mm 6-lead package, share identical pin configuration (pins 1–3 = GND, pins 4–6 = IN), and meet identical electrical specifications per Semtech's official datasheet Rev 2.5.
Does RCLAMP03354P.N require a thermal pad or heatsink for 40A surge handling?
No, RCLAMP03354P.N dissipates surge energy through its low-RDS(on) FET structure rather than a PN junction, eliminating the need for thermal pads or external heatsinks. Its DFN package relies on PCB copper area and multiple vias to ground for effective transient energy dissipation - as confirmed in Semtech's layout guidelines.
Can RCLAMP03354P.N be used on high-speed data lines like USB SuperSpeed or DisplayPort?
No, RCLAMP03354P.N is not intended for high-speed data lines. With 175pF junction capacitance at 22V, it is optimized for 22V power rail and I/O protection (e.g., USB PD VBus, load switch inputs). For SuperSpeed or DP lines, Semtech recommends low-capacitance devices such as RClamp3371ZC (<0.25pF).
What ESD and surge standards does RCLAMP03354P.N meet?
RCLAMP03354P.N meets IEC 61000-4-2 (±30kV contact/air), IEC 61000-4-4 (±4kV EFT), and IEC 61000-4-5 (40A 8/20μs, ±1kV 1.2/50μs with RS = 42Ω) - making it suitable for industrial, computing, and USB-C applications requiring full system-level EMC compliance.
