Product details
Overview
TS30111-M033QFNR 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), 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 TS30111-M033QFNR datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability under 40A surge, DFN-6 thermal and layout performance, 175pF junction capacitance at 22V, and compatibility with 22V bus systems requiring robust EOS resilience without TVS-like voltage drift.
Technical Context
The TS30111-M033QFNR 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 threshold. Unlike conventional TVS diodes, its clamping voltage remains nearly constant due to decreasing RDS(on) under increasing surge current.
It operates over –40°C to +125°C with <20mΩ dynamic resistance (8/20μs), 1120W peak pulse power rating, and maintains ≤28V clamping up to 40A across temperature - enabling reliable protection where thermal derating and voltage margin are critical, such as in USB PD 20V+ interfaces and industrial e-fuse inputs.
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 degradation. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs + 1.2/50μs combo wave, RS=2Ω) - ensures downstream ICs like USB PD controllers remain below damage thresholds during surges. |
| Peak Pulse Current | 40A (8/20μs) - supports compliance with IEC 61000-4-5 Level 4 (±1kV, RS=42Ω) on unsymmetrical lines. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds industrial and consumer ESD immunity requirements without external staging. |
| Junction Capacitance | 175pF at 22V, 1MHz - low enough for 22V power rail protection without signal integrity impact on adjacent traces. |
| Dynamic Resistance | 20mΩ (8/20μs, 1A–40A range) - enables flat clamping response and minimizes VC rise vs. current, unlike TVS diodes. |
| Package | DFN 1.6mm × 1.6mm × 0.55mm, 6-lead - enables ultra-compact placement near connectors with minimal PCB area and thermal mass. |
Pinout & Package
TS30111-M033QFNR is housed in a RoHS-compliant, halogen-free DFN-6 package (1.6mm × 1.6mm × 0.55mm) with exposed thermal pad not required - energy dissipation occurs within the silicon FET structure. All six terminals must be connected per functional role for full 40A surge capability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground return path for surge current; all three pins must be tied to solid ground plane with multiple vias to minimize inductance. |
| Pins 4, 5, 6 | IN | Protected line input - connects directly to VBus, USB PD input, or load switch VIN; all three pins conduct surge current in parallel. |
Key Features
| Feature | Design Value |
|---|---|
| FET-based transient diversion | Replaces TVS diode with active shunt FET, delivering flat clamping voltage independent of surge amplitude or temperature. |
| Stable clamping over temperature | Clamps at ≤28V from –40°C to +125°C - eliminates thermal derating calculations required for standard TVS devices. |
| High-energy surge handling | 1120W peak pulse power (8/20μs) supports repeated lightning-surge events without parametric shift or failure. |
| Low dynamic resistance | 20mΩ enables efficient current shunting with minimal IR drop - critical for maintaining tight voltage margins on 22V rails. |
| Compact DFN footprint | 1.6mm × 1.6mm saves >60% board space vs. SOT-23 or SOIC alternatives while supporting same 40A rating. |
Applications
| USB Type-C Power Delivery Input Protection | Industrial Load Switch Front-End Protection |
|---|---|
|
Use Scenario: Protecting 20–22V VBus lines in USB-C PD ports against ESD, lightning-induced surges, and hot-plug transients. IC Role / Device Role / Timing Role: Primary EOS shunt protector placed between connector and PD controller or buck converter input. Use Value: Maintains 27.5–28V clamping at 40A and 125°C - prevents overvoltage damage to PD controllers rated for ≤30V absolute max. |
Use Scenario: Shielding enable-controlled load switches (e.g., HS2950P) from EOS events on VIN in remote meters, robotics, and IoT gateways. IC Role / Device Role / Timing Role: Front-end transient suppressor limiting voltage seen by internal FET gate oxide and overvoltage protection circuitry. Use Value: Clamps below 28V even at 40A, keeping stress on load switch drain-source and OVP comparators within safe operating area. |
| Storage Device 22V Rail Protection | Industrial Equipment DC Power Input |
|
Use Scenario: Securing 22V auxiliary rails in NVMe SSD enclosures or enterprise storage backplanes against system-level ESD coupling. IC Role / Device Role / Timing Role: Single-point, low-capacitance (<175pF) surge diverter on main power input before PMIC or LDO regulators. Use Value: Prevents latch-up or permanent damage to downstream power management ICs during handling or field surges without adding signal distortion. |
Use Scenario: Hardening 22V DC input stages in programmable logic controllers (PLCs), motor drives, and HMI panels against 4kV EFT and 1kV surge events. IC Role / Device Role / Timing Role: Robust, temperature-stable EOS guard for unregulated industrial power entry points subject to long-term thermal cycling. Use Value: Delivers consistent 28V clamping across –40°C to +125°C ambient - avoids design margin erosion in harsh cabinet environments. |
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 - confirmed direct replacement per Semtech documentation and marking code mapping. | Same use cases: USB-C PD, load switch input, 22V rail protection. | Drop-in replacement; identical layout, BOM, and qualification status. |
| uClamp2411ZA | 24V working voltage, ±30kV ESD, but lower 24A IPP rating and TVS-based architecture - clamping rises with current/temperature. | Better suited for CC/SBU lines in USB-C; insufficient for 40A VBus protection. | Select only for lower-energy signal-line protection where 24V rating suffices and 24A IPP is adequate. |
Compared with TDS2211P and uClamp2411ZA, TS30111-M033QFNR offers identical surge performance and layout compatibility to TDS2211P while differing from uClamp2411ZA in both clamping stability and peak current capability - making it the sole choice for 22V, 40A front-end protection where voltage margin is constrained.

FAQ
What is the maximum continuous operating voltage for TS30111-M033QFNR?
The TS30111-M033QFNR has a reverse stand-off voltage (VRWM) of 22V, meaning it can safely operate continuously at up to 22V DC or RMS on the protected line without significant leakage or degradation. This makes it ideal for USB PD 20V+ systems and industrial 22V rails where sustained voltage margin is critical.
How does TS30111-M033QFNR differ from standard TVS diodes in clamping behavior?
Unlike standard TVS diodes whose clamping voltage rises linearly with peak pulse current (VC = VBR + IPP × RDYN), the TS30111-M033QFNR uses a surge-rated FET to maintain a nearly constant 27.5–28V clamping voltage from 1A to 40A and across –40°C to +125°C - eliminating thermal and current-dependent voltage drift.
Can TS30111-M033QFNR be used for USB Type-C SuperSpeed data line protection?
No - TS30111-M033QFNR is designed for power or high-energy I/O line protection (e.g., VBus, load switch input) with 175pF junction capacitance, which is too high for SuperSpeed differential pairs. For TX/RX lines, Semtech recommends low-capacitance devices like RClamp3371ZC (<0.25pF), as specified in the TDS2211P application notes.
What is the recommended PCB layout for optimal surge performance of TS30111-M033QFNR?
Place TS30111-M033QFNR as close as possible to the connector. Connect all three IN pins (4, 5, 6) via a single short, wide trace to the protected line, and tie all three GND pins (1, 2, 3) directly to a solid ground plane using ≥4 thermal vias. Avoid stubs or splits to minimize parasitic inductance during fast transients.
Is TS30111-M033QFNR RoHS and halogen-free compliant?
Yes - TS30111-M033QFNR meets RoHS/WEEE requirements and is halogen-free, with Pb-free lead finish and UL 94V-0 molding compound. Its DFN package is fully compatible with lead-free reflow profiles and industrial environmental compliance mandates.
