Product details
Overview
TS30042-M025QFNR 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 - enabling robust USB PD and Type-C bus protection in industrial and portable systems.
For engineers reviewing the TS30042-M025QFNR 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 load switch input protection architectures requiring sub-30V clamping.
Technical Context
The TS30042-M025QFNR uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit 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 - delivering 27.5–28V clamping at both 24A and 40A (1.2/50μs + 8/20μs combination waveform, RS = 2Ω).
It operates from −40°C to +125°C with <600nA reverse leakage at 22V, 20mΩ dynamic resistance (measured 1–40A, 8/20μs), and maintains stable clamping across temperature - unlike standard TVS devices whose VC rises with ambient temperature and IPP.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC 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 industrial surge immunity requirements for 22V systems. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds USB IF and industrial ESD immunity requirements for connector-facing protection. |
| Junction Capacitance | 175pF at 22V, 1MHz - low enough for 22V power rail protection without degrading power integrity or causing excessive filtering. |
| Dynamic Resistance | 20mΩ (1–40A, 8/20μs) - enables flat clamping response and minimizes voltage overshoot during fast-rising transients. |
Pinout & Package
TS30042-M025QFNR is housed in a RoHS-compliant, halogen-free DFN package measuring 1.6mm × 1.6mm × 0.55mm with exposed thermal pad (no internal thermal pad required - energy dissipated in silicon). All six terminals are surface-mount; pin 1 is marked with laser dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground return path for surge current - all three must be connected with low-inductance vias to maximize 40A capability. |
| 4, 5, 6 | IN | Protected line input - connects directly to VBus, USB PD power rail, or load switch input; all three pins conduct in parallel for lowest impedance path. |
Key Features
| Feature | Design Value |
|---|---|
| FET-based transient shunting | Replaces traditional TVS with active clamping - achieves near-constant VC independent of IPP and temperature. |
| Stable clamping over temperature | 27.5–28V clamping maintained from −40°C to +125°C - eliminates derating needed for TVS devices in hot environments. |
| High-energy surge rating | 1120W peak pulse power (8/20μs) - supports repeated industrial lightning surge events without degradation. |
| Low dynamic resistance | 20mΩ enables minimal voltage overshoot during fast transients - critical for protecting sensitive 24V logic interfaces. |
| Compact DFN-6 footprint | 1.6mm × 1.6mm area saves >50% board space vs. SO-8 or SOT-23 alternatives - ideal for USB Type-C and IoT edge nodes. |
Applications
| USB Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
|
Use Scenario: Protecting 20–22V USB PD power rails against ESD, lightning surges, and system-level EOS events in docking stations and portable chargers. IC Role / Device Role / Timing Role: Primary shunt protector placed between VBus and GND, activated within nanoseconds of overvoltage detection to divert surge current away from PD controller and e-fuse. Use Value: Maintains 27.5–28V clamping at full 40A surge - prevents latch-up or gate oxide damage in 24V-rated PD controllers even at 125°C ambient. |
Use Scenario: Safeguarding input pins of high-side load switches (e.g., HS2950P) in industrial meters, robotics, and remote sensors exposed to field wiring transients. IC Role / Device Role / Timing Role: Front-end transient suppressor that limits voltage seen by the load switch's internal MOSFET drain, preventing avalanche failure or gate-source overvoltage. Use Value: Clamps below 28V while handling 40A - keeps stress on load switch well within safe operating area (SOA), extending reliability in ungrounded or long-cable installations. |
| USB Type-C Connector Protection | IoT Edge Node Power Rail Protection |
|
Use Scenario: Integrated into USB Type-C receptacle circuits where VBus must withstand up to 22V and survive repeated ±30kV ESD strikes per IEC 61000-4-2. IC Role / Device Role / Timing Role: Dedicated high-current EOS suppressor for the VBus line, co-located with ultra-low-capacitance TVS (e.g., RClamp3371ZC) on data lanes. Use Value: Enables single-device 22V rail protection without compromising ESD robustness or requiring oversized TVS arrays - simplifies BOM and layout. |
Use Scenario: Protecting 12–24V input rails of battery-powered IoT gateways, smart sensors, and edge controllers deployed in electrically noisy environments. IC Role / Device Role / Timing Role: Standalone transient suppressor on main power entry point, absorbing multi-kV surges before they propagate to PMICs, microcontrollers, or communication ICs. Use Value: Delivers 40A surge handling in 1.6mm² footprint - allows compact, sealed enclosures without sacrificing surge immunity compliance (IEC 61000-4-5 Level 4). |
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 code T22 - confirmed as direct variant of TS30042-M025QFNR per Semtech documentation and packaging data. | Same USB PD, Type-C, and load switch use cases; validated in Semtech reference designs (e.g., Figure 4 & 5). | Select when sourcing from distributors carrying Semtech's standard TDS2211P.C part number - functionally and physically interchangeable. |
| uClamp2411ZA | 24V working voltage, ±30kV ESD, but lower 20A IPP rating and higher 33V clamping - uses silicon avalanche diode architecture, not FET-based shunting. | Better suited for CC/SBU lines in USB Type-C; insufficient for 40A VBus protection due to higher VC and lower surge rating. | Use only for auxiliary signal lines where capacitance <0.5pF is critical; not a replacement for TS30042-M025QFNR on power rails. |
Compared with TDS2211P (identical functional replacement) and uClamp2411ZA (lower-power signal-line alternative), TS30042-M025QFNR uniquely combines 40A surge handling, 27.5–28V clamping, and FET-based flat-response behavior - making it the only suitable option for high-reliability 22V power rail protection in thermally demanding applications.

FAQ
What is the maximum continuous operating voltage for TS30042-M025QFNR?
The TS30042-M025QFNR has a reverse stand-off voltage (VRWM) of 22V, meaning it can continuously block up to 22V DC without significant leakage or conduction. This makes TS30042-M025QFNR suitable for 20V USB PD buses and 24V industrial power rails where transient suppression is required without interfering with normal operation.
How does TS30042-M025QFNR achieve stable clamping voltage across temperature?
TS30042-M025QFNR uses a surge-rated FET activated by a precision trigger circuit - not a conventional PN-junction TVS. As surge current increases, the FET's RDS(on) decreases, maintaining clamping near the trigger circuit's breakdown voltage. This architecture ensures TS30042-M025QFNR delivers 27.5–28V clamping from −40°C to +125°C, unlike TVS diodes whose VC rises with temperature.
Can TS30042-M025QFNR replace standard TVS diodes in USB Type-C designs?
Yes - TS30042-M025QFNR is explicitly recommended by Semtech for USB Type-C VBus protection in designs supporting USB PD up to 22V. Its 40A surge rating, ±30kV ESD immunity, and stable 28V clamping make TS30042-M025QFNR superior to typical 22V TVS diodes, which exhibit rising clamping voltage with current and temperature.
What is the recommended PCB layout for TS30042-M025QFNR?
Place TS30042-M025QFNR as close as possible to the protected connector. Connect all three IN pins (4,5,6) via a single low-inductance trace to the protected line, and tie all three GND pins (1,2,3) to a solid ground plane using multiple vias. Avoid thermal pads - energy is dissipated in the silicon, and the DFN package relies on copper pour for thermal management.
Is TS30042-M025QFNR compatible with automated SMT assembly processes?
Yes - TS30042-M025QFNR is supplied in tape-and-reel format (3,000 units per 7-inch reel) and features a standard DFN-6 footprint with gull-wing leads and laser-marked pin 1. Its 0.55mm profile and Pb-free, halogen-free construction comply with IPC-7351B and JEDEC J-STD-020 moisture sensitivity level (MSL) 1 - fully compatible with reflow soldering and high-volume SMT lines.
