Product details
Overview
TS30041-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 a tightly regulated 27.5–28V clamping voltage across full temperature (−40°C to +125°C) and current range - enabling robust USB PD and load switch input protection.
For engineers reviewing the TS30041-M025QFNR datasheet, pinout, applications, or equivalent options, this page provides verified electrical specifications, DFN-6 package layout guidance, real-world clamping stability data, and validated alternatives for industrial, USB Type-C, and IoT power rail protection.
Technical Context
The TS30041-M025QFNR 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. Unlike conventional TVS diodes, its clamping voltage remains nearly constant due to decreasing RDS(on) under surge - not fixed dynamic resistance.
It operates with 22V reverse stand-off voltage (VRWM), 27.9V typical breakdown (VBR), and 20mΩ dynamic resistance (RDYN) measured from 1A to 40A. Its 175pF junction capacitance at 22V/1MHz and <600nA leakage at VRWM support low-interference integration in high-speed bus protection.
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) - ensures downstream ICs (e.g., USB PD controllers) remain below damage threshold during worst-case surge. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds Level 4 immunity requirements for consumer and industrial interfaces. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Line Surge Class 3/4 requirements for industrial equipment and USB PD inputs. |
| Junction Capacitance | 175pF @ 22V, 1MHz - low enough to avoid signal integrity degradation on 20V power rails and medium-speed control lines. |
| Dynamic Resistance | 20mΩ - enables flat clamping curve; critical for stable protection across temperature and current extremes. |
| Package | DFN 1.6 × 1.6 × 0.55 mm, 6-lead - ultra-compact footprint saves >50% board space vs. SO-8 TVS solutions. |
Pinout & Package
TS30041-M025QFNR is housed in a RoHS-compliant, halogen-free DFN-6 package (1.6mm × 1.6mm × 0.55mm) with exposed thermal pad-less construction. All six terminals are functional: three dedicated ground pins and three parallel input pins - requiring full connection for rated 40A surge handling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Low-inductance ground return path; all three must be connected to PCB ground plane via multiple vias for optimal surge current dissipation. |
| Pins 4, 5, 6 | IN | Parallel-connected input terminals for protected bus (e.g., VBUS in USB PD); shared connection ensures uniform current sharing and full 40A rating. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage stays within 27.5–28V from 1A to 40A and −40°C to +125°C - eliminates derating uncertainty in thermal design. |
| FET-based shunt topology | Replaces PN-junction TVS with low-RDS(on) MOSFET; avoids thermal runaway and enables higher energy absorption per unit area. |
| Ultra-low dynamic resistance | 20mΩ measured across full surge range - directly enables flat clamping and minimizes voltage overshoot during fast transients. |
| High EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns, 100kHz/5kHz) - protects against repetitive burst noise in industrial motor drives and PLC I/O. |
| Small-footprint DFN | 1.6 × 1.6 mm footprint with no thermal pad - simplifies layout, reduces layer count, and supports high-density USB Type-C port designs. |

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 TS30041-M025QFNR per Semtech documentation. | Same use cases: USB PD, load switch, IoT - fully interchangeable in layout and schematic. | Select when sourcing from distributors listing TDS2211P; identical performance and qualification status. |
| SMAJ22A | Standard unidirectional TVS diode; 22V VRWM, 35.5V VC @ 12.3A - higher clamping, lower IPP, and voltage-dependent clamping increases with temperature. | Limited to lower-energy surges; unsuitable for 40A IEC 61000-4-5 compliance or high-temp industrial use. | Choose only for cost-sensitive, non-critical 22V lines where clamping margin >8V is acceptable and thermal derating is managed externally. |
Compared with TS30041-M025QFNR, TDS2211P offers identical protection performance and drop-in compatibility, while SMAJ22A requires significant layout and system-level redesign due to higher clamping, thermal sensitivity, and 3× lower surge rating - making it unsuitable for USB PD or industrial 40A surge compliance.

FAQ
What is the maximum continuous operating voltage for TS30041-M025QFNR?
The TS30041-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 it suitable for nominal 20V USB PD buses and 22V industrial power rails where sustained overvoltage is not expected.
Does TS30041-M025QFNR require a thermal pad on the PCB?
No, TS30041-M025QFNR does not require a thermal pad. Its DFN-6 package dissipates surge energy through the copper traces and ground vias connected to pins 1–3. The datasheet explicitly states "no thermal pad is needed," and layout guidelines emphasize multiple vias to ground rather than thermal relief patterns.
How does TS30041-M025QFNR achieve constant clamping voltage across temperature?
TS30041-M025QFNR achieves constant clamping by using a surge-rated FET whose RDS(on) decreases under high current, counteracting the rise in trigger circuit voltage. This results in stable 27.5–28V clamping from −40°C to +125°C - unlike TVS diodes whose VC rises linearly with temperature and current.
Can TS30041-M025QFNR protect high-speed data lines like USB SS or PCIe?
No, TS30041-M025QFNR is not intended for high-speed data lines. With 175pF junction capacitance, it is optimized for power rails and medium-speed control signals. For USB SuperSpeed or PCIe lanes, Semtech recommends low-capacitance devices like RClamp3371ZC (<0.25pF), which are specified separately in the same application notes.
What is the recommended PCB layout for TS30041-M025QFNR to achieve full 40A rating?
To achieve the full 40A rating, all three GND pins (1–3) must connect to a solid ground plane using ≥3 vias each, and all three IN pins (4–6) must be shorted together with a low-inductance trace. The device must be placed within 5mm of the protected connector, and no thermal relief should be used on GND pads - per Semtech's Figure 7 layout guidelines.
