Product details
Overview
TS30011-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 TS30011-M050QFNR datasheet, pinout, applications, or equivalent options, key selection criteria include clamping stability across temperature and current, low dynamic resistance for consistent voltage limiting, DFN-6 package integration with high surge capability, and compatibility with 22V operating bus architectures.
Technical Context
The TS30011-M050QFNR uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit that senses overvoltage events. Unlike conventional TVS diodes, it maintains near-constant clamping voltage (27.5–28V) across 24–40A peak pulse current and −40°C to +125°C ambient temperature due to decreasing RDS(on) under surge conditions.
It operates with three parallel input terminals (Pins 4–6) and three ground terminals (Pins 1–3) in a 1.6mm × 1.6mm DFN package, requiring all six pins to be connected for full 40A rating. Its 175pF junction capacitance at 22V and 1MHz makes it suitable for DC power rail and lower-speed signal line protection-not high-speed data lanes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC or RMS 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 24V-rated ICs (e.g., USB PD controllers) remain below damage threshold during surge. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 surge immunity for industrial equipment and USB PD applications. |
| ESD Withstand | ±30kV contact & air per IEC 61000-4-2 - exceeds automotive and industrial ESD requirements for connector-facing protection. |
| Dynamic Resistance | 20mΩ - enables flat clamping response; reduces voltage rise ΔV = IPP × RDYN to <1V across full current range. |
| Junction Capacitance | 175pF at 22V, 1MHz - low enough for VBus filtering without affecting PD negotiation timing or load switch response. |
Pinout & Package
TS30011-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). All pins must be soldered for rated performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Low-inductance ground return path; all three must connect to solid ground plane via multiple vias to sustain 40A surge current. |
| Pins 4, 5, 6 | IN | Parallel-connected input terminals for protected line (e.g., VBus); shared connection ensures uniform current sharing and minimizes trace inductance. |
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 reliable protection without derating. |
| FET-based shunt topology | Replaces traditional TVS junctions with low-RDS(on) MOSFET; eliminates thermal runaway risk and improves surge endurance vs. silicon avalanche diodes. |
| High-energy transient handling | 1120W peak pulse power (8/20μs) supports repeated lightning-surge events in industrial gateways and metering systems. |
| Low-leakage operation | 600nA max reverse leakage at 22V enables use on always-on rails without battery drain concerns in IoT edge nodes. |
Applications
| USB Type-C Power Delivery Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting 20–22V VBus lines in USB-C receptacles against ESD, lightning-induced surges, and hot-plug transients. IC Role / Device Role / Timing Role: Primary EOS shunt suppressor placed between connector and USB PD controller or load switch input. Use Value: Maintains 27.5–28V clamping across temperature and current-prevents PD controller latch-up or overvoltage damage where standard TVS would exceed 35V at 125°C. |
Use Scenario: Safeguarding input of high-side load switches (e.g., HS2950P) in remote meters, robotics, and factory automation equipment. IC Role / Device Role / Timing Role: Front-end transient limiter that clamps surge before it reaches the load switch's internal FET drain-source junction. Use Value: Keeps clamping voltage below 30V-ensuring safe operation of 30V-rated load switches while sustaining 40A surge without degradation. |
| IoT Edge Node Power Rail Protection | Storage Device VBus Surge Suppression |
Use Scenario: Securing 22V auxiliary power rails in battery-backed smart sensors and gateway modules exposed to field ESD and induced surges. IC Role / Device Role / Timing Role: Standalone EOS protector on main DC input, upstream of PMIC or buck converter. Use Value: 130–600nA leakage at 22V preserves battery life over multi-year deployments; small DFN-6 footprint saves space in compact enclosures. |
Use Scenario: Protecting SATA or NVMe SSD VBus lines against ESD during hot-swap operations and system-level surge coupling. IC Role / Device Role / Timing Role: DC rail clamp integrated at board edge near connector to limit transient propagation into storage controller. Use Value: 175pF capacitance avoids signal integrity issues on 22V power lines while delivering 40A surge capacity-exceeding IEC 61000-4-5 compliance margin. |
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, same marking code T22; TS30011-M050QFNR is Semtech's alternate ordering designation for TDS2211P. | Direct functional and mechanical replacement; validated for identical USB PD, load switch, and industrial use cases. | Select TS30011-M050QFNR when sourcing through Aetrix Electronics' distribution channel with QFN reel packaging. |
| uClamp2411ZA | 24V working voltage, ±30kV ESD, but only 12A IPP (8/20μs); higher clamping (~33V at 12A); SOD-323 package. | Limited to CC/SBU lines or low-energy interfaces-not suitable for 22V VBus or 40A surge scenarios. | Use uClamp2411ZA only for auxiliary signal lines; TS30011-M050QFNR is required for main power rail protection. |
Compared with TDS2211P and uClamp2411ZA, TS30011-M050QFNR delivers identical high-current clamping performance in the same compact DFN-6 form factor, while uClamp2411ZA serves lower-energy roles and cannot replace TS30011-M050QFNR in VBus or load switch input positions.

FAQ
What is the exact package type and dimensions of TS30011-M050QFNR?
TS30011-M050QFNR uses a 6-pin DFN package measuring 1.6mm × 1.6mm × 0.55mm with exposed copper pad (no thermal slug). Pin 1 is marked by a laser dot; pins 1–3 are GND, pins 4–6 are IN. The land pattern follows Semtech's recommended layout with multiple vias to ground for optimal surge current handling.
Does TS30011-M050QFNR require external bias or control signals to operate?
No, TS30011-M050QFNR is fully passive and self-triggering. It contains an integrated precision trigger circuit and surge-rated FET-no external power, enable pin, or configuration is needed. It activates automatically when transient voltage exceeds ~25V breakdown threshold, diverting current to ground without delay.
Can TS30011-M050QFNR be used on high-speed data lines like USB SuperSpeed or PCIe?
No, TS30011-M050QFNR is not suitable for high-speed data lines. Its 175pF junction capacitance would severely degrade signal integrity on differential pairs. It is intended exclusively for DC power rails (e.g., VBus) and low-bandwidth control lines. For SuperSpeed lines, Semtech recommends RClamp3371ZC (<0.25pF).
How does TS30011-M050QFNR compare to standard TVS diodes in clamping behavior?
Unlike standard TVS diodes-whose clamping voltage rises linearly with peak current (VC = VBR + IPP × RDYN)-TS30011-M050QFNR maintains 27.5–28V clamping from 24A to 40A and across −40°C to +125°C. This results from its FET-based architecture, where RDS(on) decreases under surge, yielding stable protection margins.
Is TS30011-M050QFNR compliant with RoHS, REACH, and halogen-free standards?
Yes, TS30011-M050QFNR is Pb-free, halogen-free, and compliant with RoHS Directive 2011/65/EU and WEEE. Its molding compound meets UL 94V-0 flammability rating, and lead finish is matte tin. Full compliance documentation is available from Semtech upon request.
