Product details
Overview
TS30041-M050QFNR 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 20mΩ dynamic resistance. It protects USB PD, USB Type-C VBus, and load switch inputs in industrial and portable electronics.
For engineers reviewing the TS30041-M050QFNR 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 layout compatibility, and compliance with IEC 61000-4-2/4-4/4-5 surge standards.
Technical Context
The TS30041-M050QFNR 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. Unlike conventional TVS diodes, its clamping voltage remains nearly constant-27.5–28V-across 24A to 40A peak pulse current and from –40°C to +125°C operating temperature.
This architecture delivers 1120W peak pulse power handling, 175pF junction capacitance at 22V, and <600nA reverse leakage at VRWM, enabling robust protection without signal integrity degradation on high-speed or high-voltage DC rails such as USB PD VBus or industrial 24V inputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC bus voltage it can protect without leakage or conduction. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs) - ensures protected ICs (e.g., USB PD controllers) remain below damage threshold during worst-case surges. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 industrial surge immunity requirements with 2Ω source impedance. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds standard ESD immunity for handheld and connector-facing applications. |
| Dynamic Resistance | 20mΩ - enables flat clamping response and minimizes voltage rise under increasing surge current. |
| Junction Capacitance | 175pF at 22V, 1MHz - low enough for DC power rail protection without affecting downstream regulation or switching noise. |
| Operating Temperature | –40°C to +125°C - supports deployment in automotive-adjacent, industrial, and outdoor IoT environments. |
Pinout & Package
TS30041-M050QFNR is housed in a RoHS-compliant, halogen-free DFN-6 package measuring 1.6mm × 1.6mm × 0.55mm with exposed thermal pad (no internal thermal pad required; energy dissipated in silicon).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground return path for surge current; all three must be connected to maximize current sharing and minimize parasitic inductance. |
| Pins 4, 5, 6 | IN | Protected line input (e.g., VBus); parallel connection of all three pins ensures full 40A rating and uniform current distribution during transients. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies ≤0.5V from 24A to 40A and remains stable across –40°C to +125°C-enables predictable protection margin without derating. |
| FET-based shunt topology | Replaces traditional TVS junctions with low-Rds(on) MOSFET; eliminates thermal runaway risk and improves reliability under repeated surges. |
| Low dynamic resistance | 20mΩ measured between 1A–40A (8/20μs) - reduces voltage overshoot during fast-rising transients better than TVS diodes with fixed RDYN. |
| High-energy surge rating | 1120W peak pulse power (8/20μs) - supports long-duration lightning-induced surges per IEC 61000-4-5 without failure. |
| Ultra-low leakage | ≤600nA at 22V - prevents excessive quiescent current in battery-powered or always-on systems. |
Applications
| USB Type-C Power Delivery Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting the VBus line of a USB Type-C port supporting up to 20V/5A PD negotiation against ESD, lightning-induced surges, and hot-plug transients. IC Role / Device Role / Timing Role: Primary EOS shunt protector placed directly at the connector, clamping transients before they reach the PD controller or buck converter. Use Value: Maintains 27.5–28V clamping across temperature and current-ensuring PD controller (e.g., FUSB302) stays within its 30V absolute max rating even at 125°C ambient. |
Use Scenario: Safeguarding the input of high-side load switches (e.g., HS2950P) in remote meters, robotics, or factory automation equipment exposed to 24VDC field wiring. 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 catastrophic failure of the load switch during 1kV/42Ω IEC 61000-4-5 surges by holding clamping voltage well below the switch's 30–40V breakdown limit. |
| IoT Device DC Power Rail Protection | Storage Device 12–24V Bus Protection |
Use Scenario: Securing the main DC input (e.g., 22V PoE++ or adapter-derived rail) of edge AI gateways or smart sensors deployed in uncontrolled environments. IC Role / Device Role / Timing Role: Standalone transient diverter for non-data lines where low capacitance is not critical but high surge endurance is essential. Use Value: Delivers 40A surge capability in 1.6mm² footprint-reducing board area vs. stacked TVS arrays while maintaining single-device BOM simplicity. |
Use Scenario: Protecting SATA or NVMe storage enclosures with 12V/24V auxiliary power inputs from induced surges in data center or industrial rack-mount systems. IC Role / Device Role / Timing Role: High-power rail clamp positioned upstream of DC-DC converters and PMICs powering SSD controllers and flash memory. Use Value: 1120W peak power rating handles repetitive surge events common in shared power backplanes without parameter drift or wear-out. |
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, pinout, and package; same Semtech TDS family-direct functional match for TS30041-M050QFNR. | No difference in use case; validated for USB PD, load switch, and industrial 22V rail protection per Semtech documentation. | Select when sourcing flexibility or alternate marking code is needed; identical performance and layout. |
| SMAJ22A | Standard unidirectional TVS diode; 22V VRWM, 35.5V VC @ 12.3A (8/20μs), higher clamping, no constant-clamp behavior. | Higher clamping voltage limits use in 30V-tolerant systems only; unsuitable where tight voltage margins exist (e.g., USB PD). | Choose only if cost sensitivity outweighs clamping performance; requires derating above 85°C due to VC drift. |
Compared with TS30041-M050QFNR, TDS2211P offers identical protection performance and drop-in compatibility, while SMAJ22A provides lower-cost surge suppression at the expense of higher clamping voltage, reduced temperature stability, and no FET-based current-handling scalability.

FAQ
What is the maximum continuous operating voltage for TS30041-M050QFNR?
The TS30041-M050QFNR has a reverse stand-off voltage (VRWM) of 22V, meaning it reliably blocks up to 22V DC without significant leakage. This makes it suitable for protecting 20V USB PD VBus lines and other 22V-rated industrial power rails. Exceeding 22V risks premature conduction and accelerated wear.
How does TS30041-M050QFNR differ from standard TVS diodes in clamping behavior?
Unlike standard TVS diodes whose clamping voltage rises linearly with peak current (VC = VBR + IPP × RDYN), the TS30041-M050QFNR uses a triggered FET to maintain near-constant clamping-27.5–28V-from 24A to 40A and across –40°C to +125°C. This eliminates thermal derating and ensures consistent protection margins.
Can TS30041-M050QFNR be used on high-speed data lines like USB SuperSpeed?
No-TS30041-M050QFNR is not intended for high-speed data lines. Its 175pF junction capacitance would severely degrade signal integrity on USB 3.x or PCIe lanes. It is designed exclusively for DC power rails and low-frequency I/O lines. For SuperSpeed protection, Semtech recommends RClamp3371ZC (<0.25pF).
What PCB layout practices are critical for optimal performance of TS30041-M050QFNR?
Place TS30041-M050QFNR as close as possible to the protected connector. Connect all three IN pins (4,5,6) with a single low-inductance trace, and tie all three GND pins (1,2,3) directly to a solid ground plane using multiple vias. Avoid stubs or splits-this preserves surge current sharing and minimizes voltage overshoot during fast transients.
Is TS30041-M050QFNR compliant with environmental and safety standards?
Yes-TS30041-M050QFNR is Pb-free, halogen-free, and RoHS/WEEE compliant. Its molding compound meets UL 94V-0 flammability rating. It is rated for operation from –40°C to +125°C and qualified per IEC 61000-4-2 (±30kV), -4-4 (±4kV), and -4-5 (40A/8/20μs, ±1kV/1.2/50μs), making it suitable for industrial and commercial deployments.
