Semtech Corporation TS30011-M025QFNR

Overview

TS30011-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 stable 27.5–28V clamping voltage across temperature and current range. It is used in USB Type-C PD input protection to safeguard controllers from voltage overshoot during lightning surges or connector hot-plug events.

For engineers reviewing the TS30011-M025QFNR datasheet, pinout, applications, or equivalent options, key selection criteria include its constant-clamp behavior under 40A transients, ultra-low dynamic resistance (20 mΩ), DFN 1.6×1.6mm 6-lead package footprint, and suitability for industrial load switch input protection where thermal stability and low V_C margin are critical.

Technical Context

The TS30011-M025QFNR uses a surge-rated FET as the primary shunt element, activated by a precision trigger circuit when transient voltage exceeds breakdown. Unlike conventional TVS diodes, its clamping voltage remains nearly flat-27.5–28V-from 24A to 40A (1.2/50μs + 8/20μs combination waveform) due to decreasing R_DS(on) under surge.

It operates from −40°C to +125°C with reverse stand-off voltage of 22V, breakdown at 25–27.9V, and junction capacitance of 175pF at 22V/1MHz. Its solid-state architecture avoids junction heating limitations, enabling consistent performance across temperature without derating IPP.

FAQ

What is the primary function of TS30011-M025QFNR in a circuit?

The TS30011-M025QFNR functions as a transient diverting suppressor that protects 22V-rated power or I/O lines from electrical overstress events-including ESD, lightning surges, and EFT-by shunting surge current to ground via an integrated surge-rated FET. Its design ensures stable 27.5–28V clamping across 24–40A and −40°C to +125°C, making TS30011-M025QFNR ideal for USB PD and industrial load switch inputs where voltage margin is critical.

How does TS30011-M025QFNR differ from standard TVS diodes?

Unlike standard TVS diodes-which exhibit rising clamping voltage with increasing peak pulse current (V_C = V_BR + I_PP × R_DYN)-the TS30011-M025QFNR uses a triggered FET architecture that maintains near-constant clamping (27.5–28V) from 24A to 40A. This eliminates thermal derating and enables predictable protection margins. TS30011-M025QFNR also sustains performance across −40°C to +125°C without V_C drift, unlike junction-limited TVS devices.

What are the PCB layout requirements for optimal performance of TS30011-M025QFNR?

For optimal performance, TS30011-M025QFNR must be placed as close as possible to the protected connector or entry point. Pins 1–3 (GND) and 4–6 (IN) must each be shorted together with low-inductance traces; multiple vias to inner ground planes are recommended. All six pins must be soldered-omitting any GND or IN pin reduces surge current capability and degrades clamping consistency. The 1.6×1.6mm DFN footprint requires adherence to Semtech's land pattern (documented in TDS2211P Rev 2.5, page 8).

Can TS30011-M025QFNR be used on high-speed data lines like USB SuperSpeed or PCIe?

No, TS30011-M025QFNR is not suitable for high-speed data lines. Its 175pF junction capacitance at 22V would severely degrade signal integrity on differential pairs operating above 100 MHz. It is engineered exclusively for DC power rails or low-frequency I/O lines (e.g., USB-C VBUS, load switch inputs). For SuperSpeed lanes, Semtech recommends low-capacitance TVS devices such as RClamp3371ZC (<0.25pF), which are designed for signal-line protection without bandwidth loss.

Is TS30011-M025QFNR pin-compatible with other Semtech TDS devices?

TS30011-M025QFNR shares the same 6-pin DFN 1.6×1.6mm package and pinout (Pins 1–3 = GND; Pins 4–6 = IN) with TDS2211P and TDS2411P, but is not functionally interchangeable with higher-voltage variants like TDS3311P (33V). Electrical parameters-including V_RWM, V_BR, and V_C-are specific to the 22V rating. Substituting with non-22V TDS parts risks under-protection or false triggering; always verify working voltage match before replacement. TS30011-M025QFNR is a direct variant of TDS2211P and fully compatible in layout and function.
