Semtech Corporation TS13102-QFNR

Overview

TS13102-QFNR from Semtech is a transient diverting suppressor 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), 27.5–28V clamping voltage at 40A, and 20mΩ dynamic resistance. It protects USB PD, Type-C VBUS, and load switch inputs in industrial and portable electronics.

For engineers reviewing the TS13102-QFNR datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, DFN-6 package layout guidance, real-world clamping stability across temperature and current, and direct alternatives for EOS-critical designs.

Technical Context

The TS13102-QFNR 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-27.5–28V-from 24A to 40A and across –40°C to +125°C due to decreasing R_DS(on) under surge.

It operates with reverse stand-off voltage of 22V, breakdown voltage of 25–27.9V, and junction capacitance of 175pF at 22V/1MHz. Its 6-pin DFN package integrates three parallel input terminals (pins 4–6) and three ground terminals (pins 1–3) to minimize parasitic inductance and maximize surge current handling.

Key Specifications

Pinout & Package

TS13102-QFNR 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 are surface-mount; pins 1–3 are dedicated ground connections, and pins 4–6 are parallel input terminals requiring simultaneous PCB connection for full 40A rating.

FAQ

What is the clamping voltage behavior of TS13102-QFNR across surge current and temperature?

The TS13102-QFNR maintains a tightly regulated clamping voltage of 27.5–28V from 24A to 40A peak pulse current (8/20μs + 1.2/50μs combo wave) and across the full operating temperature range of –40°C to +125°C. This stability results from its FET-based shunt architecture and low 20mΩ dynamic resistance, unlike TVS diodes whose clamping rises linearly with current and temperature. TS13102-QFNR's consistent performance eliminates thermal derating and simplifies margin analysis in mission-critical designs.

Is TS13102-QFNR pin-compatible with TDS2211P?

Yes, TS13102-QFNR is pin-compatible and functionally identical to TDS2211P: both use the same 1.6mm × 1.6mm DFN-6 package, share identical pin configuration (pins 1–3 = GND, pins 4–6 = IN), and deliver matching electrical specifications including 22V working voltage, 40A peak pulse current, and 27.5–28V clamping. TS13102-QFNR is a qualified alternate marking for TDS2211P per Semtech's documentation and ordering information.

Can TS13102-QFNR be used to protect high-speed data lines like USB SuperSpeed or PCIe?

No, TS13102-QFNR is not suitable for high-speed data line protection due to its 175pF junction capacitance at 22V, which would severely degrade signal integrity on differential pairs operating above ~100MHz. It is specifically designed for 22V power rail or low-speed I/O protection (e.g., VBUS, CC, SBU, load switch enable). For USB SS or PCIe lanes, Semtech recommends low-capacitance devices like RClamp3371ZC (<0.25pF).

What is the recommended PCB layout for TS13102-QFNR to achieve full 40A surge rating?

To achieve the full 40A peak pulse current rating, all three GND pins (1–3) must connect to a solid ground plane using ≥3 thermal vias each, and all three IN pins (4–6) must be routed in parallel with equal-length, low-inductance traces directly from the protected connector. TS13102-QFNR must be placed within 5mm of the connector entry point. Avoid stubs or splits in GND or IN traces-any asymmetry reduces current sharing and compromises surge capability. No thermal pad or solder mask opening is required.

Does TS13102-QFNR meet industrial surge immunity standards such as IEC 61000-4-5?

Yes, TS13102-QFNR is rated for 40A peak pulse current under the IEC 61000-4-5 8/20μs waveform and withstands ±1kV (1.2/50μs voltage / 8/20μs current combo wave, RS = 42Ω) on unsymmetrical lines-meeting Level 4 industrial surge immunity requirements. Its constant-clamp behavior ensures protected circuits remain below damage thresholds even under worst-case surge conditions at elevated ambient temperatures, making it suitable for DIN-rail PLCs, motor drives, and outdoor IoT gateways.
