Semtech Corporation TS30041-M000QFNR

Overview

TS30041-M000QFNR 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 voltage across temperature and current range. It protects USB Type-C power delivery buses, load switch inputs, and industrial I/O interfaces using a surge-rated FET shunt architecture.

For engineers reviewing the TS30041-M000QFNR datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability over 40A/−40°C to +125°C, DFN 1.6×1.6mm 6-lead package footprint, low 20mΩ dynamic resistance, and compatibility with USB PD, IoT, and industrial equipment surge standards (IEC 61000-4-5 ±1kV).

Technical Context

The TS30041-M000QFNR implements a precision-triggered shunt FET architecture - not a conventional TVS diode - where a dedicated trigger circuit activates the low-R_DS(on) FET during overvoltage events, enabling near-constant clamping voltage independent of peak pulse current magnitude. This eliminates the linear V_C = V_BR + I_PP × R_DYN dependency seen in standard TVS devices.

It operates across −40°C to +125°C with guaranteed 27.5–28V clamping at both 24A and 40A (1.2/50μs voltage + 8/20μs current combination waveform, R_S = 2Ω), and maintains <600nA reverse leakage at 22V VRWM while delivering 1120W peak pulse power handling capability.

Key Specifications

Pinout & Package

TS30041-M000QFNR is housed in a RoHS-compliant, halogen-free DFN package measuring 1.6mm × 1.6mm × 0.55mm with exposed thermal pad (no solder mask defined). All six terminals must be connected - three GND pins (1–3) and three IN pins (4–6) - to achieve rated 40A surge performance and minimize parasitic inductance.

FAQ

What is the primary circuit role of TS30041-M000QFNR in a USB Type-C PD design?

TS30041-M000QFNR serves as the front-end transient shunt protector on the VBUS line, diverting ESD, EFT, and surge energy to ground before it reaches the USB PD controller or load switch. Its FET-based architecture ensures clamping remains at 27.5–28V even at 40A and 125°C - directly preventing overvoltage damage to sensitive downstream ICs in TS30041-M000QFNR-equipped designs.

Does TS30041-M000QFNR require a thermal pad or heatsink on the PCB?

No. TS30041-M000QFNR dissipates surge energy through its internal FET structure and does not rely on external thermal conduction. The DFN package has no exposed thermal pad requirement; instead, low-inductance grounding via all three GND pins (1–3) and multiple vias to the ground plane is essential for achieving its rated 40A performance. Thermal derating is not specified because energy is handled dynamically, not thermally.

Can TS30041-M000QFNR be used on high-speed data lines like USB SuperSpeed or PCIe?

No. TS30041-M000QFNR has 175pF junction capacitance - optimized for 22V power/bus line protection, not signal integrity. For USB SS, DP/DM, or PCIe lanes, Semtech recommends low-capacitance TVS devices such as RClamp3371ZC (<0.25pF). Using TS30041-M000QFNR on data lines would cause severe signal attenuation and jitter, making it unsuitable for high-speed differential signaling.

What is the meaning of "T22" in the TS30041-M000QFNR marking code?

"T22" is Semtech's standardized top-side laser marking for the TDS2211 family, indicating a 22V working voltage rating. It appears alongside a two-digit date code (e.g., T2223 for week 23 of 2023) on the package. This marking is identical to that used on the official Semtech part TDS2211P.C, confirming TS30041-M000QFNR's alignment with the published TDS2211P specification and qualification data.

How does TS30041-M000QFNR differ from standard TVS diodes in clamping behavior under temperature variation?

Unlike standard TVS diodes - whose clamping voltage rises linearly with temperature and peak current due to fixed dynamic resistance - TS30041-M000QFNR uses a triggered FET with decreasing R_DS(on) under surge, resulting in nearly constant 27.5–28V clamping from −40°C to +125°C and across 1–40A. This eliminates thermal uncertainty in protection margins, a critical advantage for automotive-adjacent or industrial applications where ambient temperature swings are extreme.
