Product details
Overview
TS30041-M015QFNR from Semtech is a Transient Diverting Suppressor (TDS) designed for high-energy EOS protection of 22V-rated power or I/O lines. It delivers ±30kV IEC 61000-4-2 ESD immunity, 40A peak pulse current (8/20μs), and stable 27.5–28V clamping across temperature and current range - deployed in USB Type-C PD input protection and industrial load switch front-end circuits.
For engineers reviewing the TS30041-M015QFNR datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability under 40A surge, DFN-6 thermal robustness up to +125°C, low 20mΩ dynamic resistance, and compatibility with 22V bus architectures requiring sub-28V protection thresholds.
Technical Context
The TS30041-M015QFNR uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit when transient voltage exceeds breakdown. Unlike conventional TVS diodes, its clamping voltage remains nearly constant due to decreasing RDS(on) under surge, not fixed dynamic resistance.
It operates across –40°C to +125°C with <175pF junction capacitance at 22V reverse bias and <600nA leakage at rated stand-off voltage. The device is optimized for unsymmetrical line protection, meeting IEC 61000-4-5 ±1kV (1.2/50μs, RS=42Ω) and IEC 61000-4-4 ±4kV EFT standards.
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) - ensures downstream ICs (e.g., USB PD controllers) remain below damage threshold during worst-case surge |
| Peak Pulse Current | 40A (8/20μs) - supports industrial-level lightning/surge immunity per IEC 61000-4-5 |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - eliminates need for secondary ESD stages in portable interfaces |
| Dynamic Resistance | 20mΩ - enables flat clamping curve and minimizes voltage overshoot during fast-rising transients |
| Junction Capacitance | 175pF at 22V, 1MHz - compatible with medium-speed power/data lines (e.g., USB PD VBUS, load switch inputs) |
| Operating Temp | –40°C to +125°C - supports deployment in automotive-grade industrial enclosures and powered USB hubs |
Pinout & Package
TS30041-M015QFNR is housed in a RoHS-compliant 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 |
|---|---|---|
| 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 (e.g., VBUS or load switch VIN); all three pins are internally paralleled and must be shorted externally for full 40A rating |
Key Features
| Feature | Design Value |
|---|---|
| FET-based transient shunting | Replaces traditional TVS with active switching: clamping voltage stays stable across 1–40A surge range instead of rising linearly |
| Temperature-stable clamping | Clamps at ~27.5V from –40°C to +125°C - avoids derating or overdesign needed with conventional TVS |
| High-energy surge rating | 1120W peak pulse power (8/20μs) - meets IEC 61000-4-5 Level 4 for industrial equipment |
| Low-leakage protection | <600nA reverse leakage at 22V - prevents battery drain in always-on IoT and metering applications |
| Compact DFN footprint | 1.6mm × 1.6mm area - saves >50% board space vs. SOT-23 or SOIC alternatives with comparable ratings |
Applications
| USB Type-C Power Delivery Protection | Industrial Load Switch Input Protection |
|---|---|
|
Use Scenario: Protecting VBUS lines in USB-C ports supporting up to 20V/5A PD negotiation against ESD, lightning-induced surges, and hot-plug transients. IC Role / Device Role / Timing Role: Primary front-end EOS suppressor placed between connector and PD controller/load switch, clamping transients before they reach sensitive silicon. Use Value: Maintains 27.5V clamping at 40A and 125°C - prevents false OVP trips and ensures PD controller survival where standard TVS would exceed 35V at same conditions. |
Use Scenario: Safeguarding input terminals of high-side load switches (e.g., HS2950P) in remote meters, robotics, and factory automation systems exposed to field wiring surges. IC Role / Device Role / Timing Role: Surge diverter placed directly at load switch VIN pin to limit voltage stress on internal MOSFET gate oxide and drain-source junction. Use Value: Limits clamping to ≤28V across full temperature range - keeps load switch within safe operating area (SOA) during 40A 8/20μs events, avoiding latch-up or permanent failure. |
| IoT Edge Node Power Bus Protection | Storage Device 22V Rail Protection |
|
Use Scenario: Securing 22V auxiliary rails powering cellular modems, GNSS receivers, or sensor fusion modules in battery-backed edge gateways. IC Role / Device Role / Timing Role: Standalone EOS protector on main DC input, coordinated with upstream fuse and downstream LDOs to form layered defense. Use Value: Delivers ±30kV ESD immunity and 4kV EFT robustness while adding only 175pF capacitance - no signal integrity impact on 100kHz–1MHz control buses sharing the rail. |
Use Scenario: Protecting 22V power inputs of NVMe SSD enclosures, SAS backplanes, or enterprise HDD trays subjected to hot-swap and backplane coupling transients. IC Role / Device Role / Timing Role: Point-of-load suppressor mounted adjacent to connector to intercept surges before reaching PMIC or storage controller power domains. Use Value: Enables compliance with IEC 61000-4-5 Level 4 (±1kV) using single device - eliminates need for cascaded TVS+MOV solutions that increase BOM count and layout complexity. |
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 drop-in replacement per Semtech documentation | No functional or layout change required; validated for USB-C PD and load switch use cases | Select TS30041-M015QFNR for Aetrix supply chain continuity; TDS2211P remains valid for legacy design reuse |
| SP1003-02HTG | Lower 30A IPP rating, higher 33V clamping at 30A, 25pF capacitance - uses SiC TVS architecture, not FET-based | Acceptable for lower-energy 22V applications but lacks flat-clamp behavior and temperature stability of TS30041-M015QFNR | Choose SP1003-02HTG only if cost sensitivity outweighs clamping precision and thermal margin requirements |
Compared with TDS2211P and SP1003-02HTG, TS30041-M015QFNR offers identical performance and drop-in compatibility with TDS2211P while providing superior clamping stability and temperature resilience versus the SiC TVS alternative - making it optimal for mission-critical 22V bus protection where voltage margin is constrained.

FAQ
What is the primary protection function of the TS30041-M015QFNR?
The TS30041-M015QFNR functions as a Transient Diverting Suppressor (TDS) that actively shunts high-energy electrical overstress (EOS) events - including ESD, lightning surges, and EFT - away from sensitive downstream components. Unlike passive TVS diodes, it uses a triggered FET to maintain a stable ~27.5V clamping voltage across its full 40A surge range and –40°C to +125°C operating temperature, making TS30041-M015QFNR ideal for 22V bus protection where voltage margin is tight.
Is TS30041-M015QFNR pin-compatible with TDS2211P?
Yes, TS30041-M015QFNR is a direct pin-to-pin and functional replacement for TDS2211P: both use identical DFN-6 (1.6mm × 1.6mm) packages with matching pin 1 location, GND on pins 1–3, and IN on pins 4–6. Electrical specifications - including 22V working voltage, 40A peak pulse current, and 27.5–28V clamping - are fully aligned, confirming TS30041-M015QFNR as a seamless drop-in option for existing TDS2211P designs.
What is the maximum clamping voltage of TS30041-M015QFNR under surge conditions?
The TS30041-M015QFNR clamps at 27.5–28V when subjected to 40A peak pulse current (8/20μs waveform) with 2Ω source impedance, and maintains this value across –40°C to +125°C. This stable clamping - enabled by its FET-based architecture - is significantly lower and more consistent than conventional TVS devices, which typically exceed 35V at same conditions and degrade further with temperature rise. That consistency makes TS30041-M015QFNR highly reliable for protecting 22V-rated ICs like USB PD controllers.
Can TS30041-M015QFNR be used for USB Type-C CC line protection?
No, TS30041-M015QFNR is not suitable for USB Type-C CC (Configuration Channel) line protection. Its 175pF junction capacitance and 22V working voltage are optimized for high-current power lines (e.g., VBUS), not low-voltage, high-speed signaling lines requiring sub-0.5pF capacitance. For CC/SBU protection, Semtech recommends uClamp2411ZA - a 24V, ultra-low-capacitance TVS. TS30041-M015QFNR should be applied only to VBUS or load switch inputs where its 40A surge capability and stable clamping deliver measurable system-level reliability benefits.
Does TS30041-M015QFNR require a thermal pad on the PCB?
No, TS30041-M015QFNR does not require an external thermal pad. Its DFN-6 package dissipates surge energy directly through the silicon die and bond wires, not via conduction to a heatsink or PCB copper. Semtech explicitly states "no thermal pad is needed" in the datasheet, and recommends connecting all GND pins (1–3) to a solid ground plane using multiple vias to minimize inductance - not to enhance thermal transfer. Layout focus should be on minimizing trace length between connector and TS30041-M015QFNR, not thermal copper area.
