Product details
Overview
TS30041-M033QFNR from Semtech is a transient diverting suppressor designed for high-energy EOS protection of 22V-rated power or I/O lines, featuring ±30kV IEC 61000-4-2 ESD immunity, 40A (8/20μs) peak pulse current handling, 27.5–28V clamping voltage at 40A, and 20mΩ dynamic resistance - deployed in USB PD and load switch input protection.
For engineers reviewing the TS30041-M033QFNR datasheet, pinout, applications, or equivalent options, key selection criteria include clamping stability across temperature and current, low dynamic resistance for minimal voltage overshoot, DFN-6 package integration with high-current PCB layout requirements, and compatibility with 22V bus systems requiring robust industrial-grade surge resilience.
Technical Context
The TS30041-M033QFNR uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit that senses overvoltage events and rapidly shunts transient current to ground. Its clamping voltage remains nearly constant (27.5–28V) from 24A to 40A due to decreasing RDS(on) under surge conditions.
Unlike conventional TVS diodes, this device maintains stable clamping across −40°C to +125°C and delivers 1120W peak pulse power (8/20μs), with junction capacitance of 175pF at 22V and reverse leakage ≤600nA - enabling reliable protection in thermally demanding USB Type-C and industrial power rail applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC operating voltage on protected line without triggering |
| Clamping Voltage | 27.5–28V at 40A (8/20μs) - limits transient overvoltage seen by downstream ICs during lightning/surge events |
| Peak Pulse Current | 40A (8/20μs) - supports compliance with IEC 61000-4-5 ±1kV industrial surge standard (RS = 42Ω) |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds Level 4 immunity for handheld and connector-facing interfaces |
| Dynamic Resistance | 20mΩ - ensures minimal voltage rise under high di/dt transients, critical for fast-rising EOS events |
| Junction Capacitance | 175pF at 22V, 1MHz - low enough for 22V power rail protection without signal integrity impact |
Pinout & Package
TS30041-M033QFNR is housed in a RoHS-compliant DFN-6 package measuring 1.6mm × 1.6mm × 0.55mm with exposed thermal pad not required; all six terminals are electrically active and must be connected per layout guidelines to achieve rated surge performance.

|---|---|---|
| Pins 1, 2, 3 | GND | Common ground return path for surge current; multiple vias recommended to minimize inductance |
| Pins 4, 5, 6 | IN | Protected line input - all three pins must be paralleled to handle full 40A peak pulse current |
Key Features
| Feature | Design Value |
|---|---|
| Constant clamping across current range | 27.5–28V from 24A to 40A enables predictable downstream voltage stress regardless of surge magnitude |
| Stable clamping over temperature | No increase in VC from −40°C to +125°C eliminates derating concerns in industrial thermal environments |
| Low dynamic resistance | 20mΩ minimizes IR drop during fast transients, reducing overshoot beyond clamping threshold |
| High-energy surge capability | 1120W peak pulse power rating supports repeated exposure to IEC 61000-4-5 Level 4 surges |
Applications
| USB Type-C Power Delivery Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting 20–22V VBus lines in USB-C connectors supporting up to 100W PD, exposed to ESD and system-level surges. IC Role / Device Role / Timing Role: Transient diverting suppressor placed directly at connector entry point to clamp EOS before reaching PD controller or power multiplexer. Use Value: Maintains 27.5–28V clamping across temperature and current, preventing damage to 22V-tolerant PD controllers where conventional TVS would exceed safe voltage thresholds at elevated temperatures. | Use Scenario: Safeguarding input rails of industrial-grade load switches (e.g., HS2950P) in remote meters, robotics, and IoT edge nodes subject to lightning-induced surges. IC Role / Device Role / Timing Role: Primary front-end EOS protector for high-side FET gate drive and internal circuitry of e-fuse/load switch ICs. Use Value: Clamps below the breakdown limit of internal switch FETs while dissipating 1120W peak energy, extending reliability in ungrounded or field-deployed equipment. |
| Notebook/Convertible Tablet VBus Protection | 22V Industrial Power Rail Protection |
Use Scenario: Securing main battery or adapter input rails in thin-client notebooks and 2-in-1 tablets where board space and thermal constraints limit traditional TVS use. IC Role / Device Role / Timing Role: Compact, low-profile transient suppressor integrated into compact power delivery paths near DC jack or battery connector. Use Value: 1.6mm × 1.6mm DFN-6 footprint saves >50% area vs. SOD-323 TVS alternatives while delivering superior clamping consistency and higher surge margin. | Use Scenario: Protecting 22V auxiliary power supplies in programmable logic controllers (PLCs), motor drives, and factory automation I/O modules. IC Role / Device Role / Timing Role: Standalone EOS guard for non-isolated 22V distribution rails feeding sensors, actuators, or communication interfaces. Use Value: Enables single-device compliance with IEC 61000-4-5 (±1kV) and IEC 61000-4-2 (±30kV) without cascaded protection stages or voltage margin compromises. |
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 marking and reel packaging - confirmed functional and mechanical replacement | Same USB PD, load switch, and 22V rail use cases; validated in Semtech reference designs | Select when sourcing from Semtech-authorized channels with full traceability and lifecycle support |
| uClamp2411ZA | 24V working voltage, lower 20A IPP rating, 0.25pF capacitance optimized for CC/SBU lines - not rated for 40A power rail surges | Designed for low-capacitance data-line protection (CC/SBU), not power rail clamping | Use only for auxiliary signal lines; unsuitable as direct replacement for TS30041-M033QFNR's 22V/40A power rail role |
Compared with TDS2211P, TS30041-M033QFNR offers identical performance and form factor, making it a seamless drop-in option; versus uClamp2411ZA, it delivers 2× peak current capacity and 22V-specific clamping stability essential for power rail protection - not substitutable in high-energy applications.

FAQ
What is the maximum continuous operating voltage for TS30041-M033QFNR?
The TS30041-M033QFNR has a reverse stand-off voltage (VRWM) of 22V, meaning it can safely operate continuously at up to 22V DC on the protected line without triggering conduction. This makes TS30041-M033QFNR ideal for USB PD 20V–22V bus protection and other 22V industrial power rails where sustained voltage tolerance is required.
Does TS30041-M033QFNR require a thermal pad on the PCB?
No, TS30041-M033QFNR does not require a thermal pad. The device dissipates surge energy through its internal FET structure rather than junction heating, and Semtech's datasheet explicitly states "no thermal pad is needed." Proper PCB layout - including short, wide traces and multiple vias to ground for Pins 1–3 - is sufficient for full 40A surge performance of TS30041-M033QFNR.
How does TS30041-M033QFNR differ from standard TVS diodes in clamping behavior?
TS30041-M033QFNR uses a triggered FET architecture that maintains nearly constant clamping voltage (27.5–28V) across its full 24–40A peak pulse range and from −40°C to +125°C. In contrast, standard TVS diodes exhibit linear VC rise with current (VC = VBR + IPP × RDYN) and increased clamping at higher temperatures - a key distinction confirmed in TS30041-M033QFNR's functional operation and comparative graphs.
Can TS30041-M033QFNR be used on high-speed data lines like USB SuperSpeed?
No, TS30041-M033QFNR is not suitable for high-speed data lines such as USB SuperSpeed (TX/RX), DP/DM, or PCIe. With 175pF junction capacitance, it would severely degrade signal integrity. TS30041-M033QFNR is intended exclusively for 22V power or low-speed I/O lines; for data lines, Semtech recommends low-capacitance devices like RClamp3371ZC (<0.25pF), as specified in official USB Type-C protection schematics involving TS30041-M033QFNR.
What is the pin configuration and layout requirement for optimal performance of TS30041-M033QFNR?
TS30041-M033QFNR uses a 6-pin DFN package: Pins 1–3 are GND, Pins 4–6 are IN. All three GND pins must connect to a solid ground plane via multiple vias, and all three IN pins must be paralleled with a single low-inductance trace to the protected line. Placement within 2mm of the connector is mandatory to minimize coupling - requirements explicitly defined in the TS30041-M033QFNR datasheet layout guidelines.
