Product details
Overview
TS30041-M018QFNR 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 stable 27.5–28V clamping voltage across full temperature range (−40°C to +125°C), enabling robust USB PD and industrial load switch input protection.
For engineers reviewing the TS30041-M018QFNR datasheet, pinout, applications, or equivalent options, this page provides verified electrical parameters, DFN-6 package layout guidance, functional role in surge diversion, and validated alternative options for 22V bus protection in USB Type-C, IoT, and industrial equipment designs.
Technical Context
The TS30041-M018QFNR uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit that senses overvoltage events. Unlike conventional TVS diodes, its clamping voltage remains nearly constant-27.5–28V at both 24A and 40A-due to the FET's decreasing RDS(on) under surge conditions.
It operates with 22V reverse stand-off voltage (VRWM) and 25–27.9V breakdown (VBR), exhibits low dynamic resistance (20 mΩ), and maintains stable junction capacitance (175 pF at 22V/1MHz) and leakage (<600 nA) across −40°C to +125°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22 V - defines maximum continuous DC operating voltage on protected line without triggering |
| Clamping Voltage | 27.5–28 V at 40A (8/20μs) - ensures downstream ICs (e.g., USB PD controllers) remain below damage threshold during worst-case surge |
| Peak Pulse Current | 40 A (8/20μs) - meets IEC 61000-4-5 Level 4 industrial surge immunity requirements |
| ESD Withstand | ±30 kV contact & air (IEC 61000-4-2) - exceeds automotive and industrial ESD immunity standards |
| Junction Capacitance | 175 pF at 22 V, 1 MHz - low enough for 22V power rail protection without signal integrity impact |
| Dynamic Resistance | 20 mΩ - enables flat clamping curve and minimal voltage rise under increasing surge current |
| Operating Temp | −40°C to +125°C - supports deployment in extended-temperature industrial and automotive environments |
Pinout & Package
TS30041-M018QFNR is housed in a RoHS-compliant, halogen-free DFN package measuring 1.6 mm × 1.6 mm × 0.55 mm with 6 leads and UL 94V-0 molding compound. All pins must be connected for rated surge performance: three GND pins provide low-inductance return path; three IN pins share surge current handling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground terminals - must be tied together and connected to PCB ground plane via multiple vias to minimize parasitic inductance |
| 4, 5, 6 | IN | Protected line input - all three pins connect in parallel to the same bus (e.g., VBUS) to distribute surge current and maximize IPP capability |
Key Features
| Feature | Design Value |
|---|---|
| FET-based transient diversion | Replaces traditional TVS with active shunt FET, delivering flat clamping independent of surge magnitude or temperature |
| Stable clamping across temperature | 27.5–28 V clamping maintained from −40°C to +125°C - eliminates derating concerns in hot industrial enclosures |
| High-energy surge rating | 1120 W peak pulse power (8/20μs) - sustains 40A surges without degradation or thermal runaway |
| Low dynamic resistance | 20 mΩ - minimizes IR drop during conduction, preserving clamping accuracy under fast-rising transients |
| Compact DFN footprint | 1.6 mm × 1.6 mm - saves >50% board area vs. SO-8 or SOT-23 TVS solutions while supporting same surge rating |
Applications
| USB Type-C Power Delivery | Industrial Load Switch Input Protection |
|---|---|
|
Use Scenario: Protecting 20–22V VBUS lines in USB-C ports with Power Delivery negotiation. IC Role / Device Role / Timing Role: Transient diverting suppressor placed at connector entry point to clamp lightning-induced surges and ESD before reaching PD controller or e-fuse. Use Value: Maintains 27.5–28V clamping at 40A and 125°C - prevents overvoltage damage to sensitive PD ICs where standard TVS would exceed 38V at same conditions. |
Use Scenario: Safeguarding input of industrial-grade load switches (e.g., HS2950P) against EOS in remote meters and robotics. IC Role / Device Role / Timing Role: Primary front-end surge protector on VIN rail, limiting voltage seen by internal FET gate oxide and overvoltage protection circuitry. Use Value: Clamps below 28V across full temperature range - avoids latch-up or permanent failure of load switch during repeated 1kV/42Ω surges per IEC 61000-4-5. |
| IoT Edge Node Power Rails | Storage Device 22V Backup Supplies |
|
Use Scenario: Securing 22V auxiliary power inputs in battery-backed IoT gateways exposed to field ESD and induced surges. IC Role / Device Role / Timing Role: Standalone EOS protector on main DC input, coordinated with low-capacitance TVS on data lines. Use Value: Delivers ±30kV ESD immunity and 40A surge handling in 1.6 mm² footprint - enables compact, ruggedized enclosure design without external heatsinking. |
Use Scenario: Protecting 22V backup power rails in enterprise SSDs and NVMe storage modules during hot-plug or system-level surge events. IC Role / Device Role / Timing Role: Bus-level transient suppressor placed between power source and storage controller power domain. Use Value: Stable 27.5–28V clamping ensures NAND flash power management ICs remain within absolute maximum ratings during 8/20μs transients up to 40A. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDS2211P | Same die, identical electrical specs and DFN-6 package - confirmed pin-to-pin compatible replacement per Semtech documentation | No functional difference; used interchangeably in USB-C, load switch, and industrial designs | Select when requiring direct Semtech-specified drop-in replacement with full documentation traceability |
| SMAJ22A | Standard unidirectional TVS diode; 22V VRWM, 35.5V VC @ 12.3A - higher clamping, no temperature stability, fixed RDYN | Limited to lower-energy surges; requires derating above 85°C and cannot meet 40A/28V requirement | Choose only for cost-sensitive, non-critical 22V lines where clamping voltage margin >7V is acceptable |
Compared with TS30041-M018QFNR, TDS2211P offers identical protection performance and layout compatibility, while SMAJ22A provides lower-cost but significantly degraded clamping accuracy, temperature stability, and surge capacity - making it unsuitable for USB PD or industrial 40A surge compliance.

FAQ
What is the primary circuit function of TS30041-M018QFNR?
TS30041-M018QFNR functions as a transient diverting suppressor that actively shunts high-energy EOS events-including ESD, lightning surges, and EFT-to ground using a precision-triggered surge-rated FET. Unlike passive TVS diodes, it maintains a stable 27.5–28V clamping voltage across its full 40A surge range and −40°C to +125°C operating temperature, making TS30041-M018QFNR ideal for protecting 22V power rails in USB PD and industrial systems.
Does TS30041-M018QFNR require external bias or control signals?
No, TS30041-M018QFNR operates autonomously with no external bias, enable pins, or configuration interfaces. Its internal trigger circuit activates the shunt FET when input voltage exceeds the breakdown threshold (~25–27.9V), and the device returns to high-impedance standby mode once the transient subsides. This self-contained operation makes TS30041-M018QFNR suitable for always-on protection without firmware or system-level intervention.
How does TS30041-M018QFNR differ from standard TVS diodes in clamping behavior?
TS30041-M018QFNR delivers near-constant clamping voltage (27.5–28V) across its entire 40A surge range and full temperature span due to its FET-based architecture and decreasing RDS(on). In contrast, standard TVS diodes exhibit linear clamping rise (VC = VBR + IPP × RDYN), causing clamping to exceed 38V at 24A and 125°C. This fundamental difference makes TS30041-M018QFNR uniquely capable of protecting sensitive 22V-rated ICs under worst-case thermal and surge conditions.
Can TS30041-M018QFNR be used on data lines such as USB SuperSpeed or DisplayPort?
No, TS30041-M018QFNR is not intended for high-speed data line protection due to its 175 pF junction capacitance, which would severely degrade signal integrity on differential pairs operating above ~100 MHz. It is specifically designed for 22V power rail or low-speed I/O protection. For USB SS, DP, or DM lines, Semtech recommends low-capacitance TVS devices like RClamp3371ZC (<0.25 pF); TS30041-M018QFNR complements those by protecting the associated VBUS rail.
What PCB layout practices maximize TS30041-M018QFNR surge performance?
To maximize TS30041-M018QFNR performance, place it as close as possible to the protected connector, route all three IN pins (4–6) in parallel with a single short trace to the bus, and tie all three GND pins (1–3) directly to a solid ground plane using ≥3 vias. Avoid thermal pads or isolated copper - energy is dissipated internally. This layout minimizes parasitic inductance and ensures full 40A surge current sharing across all pins, as validated in Semtech's application notes for TS30041-M018QFNR.
