Product details

Overview

TDS2211P from Semtech is a transient diverting suppressor designed to protect single 22V I/O or power lines against EOS events, featuring ±30kV IEC 61000-4-2 ESD immunity, 40A (8/20μs) peak pulse current handling, and stable 27.5–28V clamping voltage across temperature and current range - deployed in USB Type-C PD bus protection and industrial load switch input stages.

For engineers reviewing the TDS2211P datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability under 40A surge, DFN-6 thermal and layout performance, 175pF junction capacitance at 22V, and compatibility with 22V working voltage systems requiring robust EOS defense without TVS-like voltage drift.

Technical Context

The TDS2211P 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 threshold. Unlike conventional TVS diodes, its clamping voltage remains nearly constant due to decreasing R_DS(on) under increasing IPP - delivering 27.5–28V clamping at both 24A and 40A (1.2/50μs + 8/20μs combination waveform, R_S = 2Ω).

It operates from −40°C to +125°C with <600nA reverse leakage at 22V, 20mΩ dynamic resistance (measured 1–40A, 8/20μs), and maintains stable clamping across temperature - unlike standard TVS devices whose V_C rises with both current and ambient temperature.

Key Specifications

Parameter	Value and Actual Design Meaning
Working Voltage	22V - defines maximum continuous DC operating voltage of protected line without leakage or conduction.
Clamping Voltage	27.5–28V at 40A (8/20μs + 1.2/50μs combo wave) - ensures downstream ICs (e.g., USB PD controllers) remain below damage threshold during surge.
Peak Pulse Current	40A (8/20μs) - meets IEC 61000-4-5 Level 4 industrial surge immunity requirements for unsymmetrical lines.
ESD Withstand	±30kV contact & air (IEC 61000-4-2) - exceeds automotive and industrial ESD immunity standards for connector-facing protection.
Junction Capacitance	175pF at 22V, 1MHz - low enough for 22V power rail protection without signal integrity impact on moderate-speed buses.
Dynamic Resistance	20mΩ - enables flat clamping response; critical for maintaining consistent V_C across full 1–40A surge range.

Pinout & Package

Package: DFN-6 (1.6mm × 1.6mm × 0.55mm), Pb-free, RoHS/WEEE compliant, UL 94V-0 molding compound, tape-and-reel packaging (3,000 pcs/reel).

Pin/Terminal	Circuit Role	Design Meaning
Pins 1, 2, 3	GND	Common ground return path for surge current; all three must be connected to maximize current sharing and minimize parasitic inductance.
Pins 4, 5, 6	IN	Protected line input; tied together to form single high-current path to bus - required for full 40A rating and optimal thermal distribution.

Key Features

Feature	Design Value
FET-based shunt architecture	Enables near-constant clamping voltage (27.5–28V) across 1–40A and −40°C to +125°C - eliminates TVS-style V_C drift with current/temperature.
22V working voltage rating	Matches USB PD 20V nominal + margin and industrial 24V rail derating - avoids overvoltage stress during normal operation.
±30kV ESD immunity	Exceeds IEC 61000-4-2 Level 4, enabling direct front-panel or connector placement without additional shielding or spacing.
Low 20mΩ dynamic resistance	Ensures minimal IR drop during surge, preserving clamping accuracy and reducing self-heating under repeated transients.
175pF junction capacitance	Minimizes loading on 22V power rails while remaining compatible with load switch and e-fuse input protection use cases.

Equivalent & Alternatives

The following parts are listed as comparable options for similar transient suppression applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SP1003-02WTG	TVS diode array; 22V standoff, 33V clamping at 24A (8/20μs); higher V_C drift with temperature and current.	Limited to lower-energy surges; less suitable for sustained 40A industrial transients or high-temp environments.	Choose for cost-sensitive designs where 33V clamping margin is acceptable and thermal derating is managed externally.
SM712-TR	Bi-directional TVS; 12V standoff, 28V clamping; rated for 30A (8/20μs); not rated for 22V continuous operation.	Requires series resistor or voltage derating for 22V rails; unsuitable for direct connection to unprotected 22V bus.	Use only with external current-limiting or in sub-15V systems; not a functional replacement for TDS2211P's 22V working voltage capability.

Compared with SP1003-02WTG and SM712-TR, the TDS2211P delivers superior clamping stability, higher surge rating, and native 22V compatibility - making it the only option qualified for direct 22V bus protection in USB PD and industrial load switch applications without design compromises.

Manufacturer

Semtech Corporation is a U.S.-based fabless semiconductor company specializing in analog and mixed-signal ICs for precision sensing, protection, and signal integrity.

The TDS family was developed to replace conventional TVS diodes in high-reliability 22V–36V power and interface protection, emphasizing flat clamping, temperature stability, and FET-based surge handling for industrial and USB-C infrastructure.

FAQ

What is the maximum continuous operating voltage for TDS2211P?

The TDS2211P has a reverse stand-off voltage (V_RWM) of 22V, meaning it can continuously block up to 22V DC without significant leakage or conduction. This makes TDS2211P suitable for protecting 20V USB PD buses and 22V industrial power rails where sustained voltage exposure occurs. Exceeding 22V risks premature triggering or accelerated degradation.

How does TDS2211P differ from standard TVS diodes in clamping behavior?

Unlike standard TVS diodes whose clamping voltage rises linearly with peak pulse current (V_C = V_BR + I_PP × R_DYN), the TDS2211P uses a triggered FET shunt that maintains ~27.5–28V clamping from 1A to 40A and across −40°C to +125°C. This eliminates thermal and current-dependent V_C drift - a key advantage confirmed in Figure 3 of the TDS2211P datasheet.

Can TDS2211P be used to protect high-speed data lines like USB SuperSpeed?

No - the TDS2211P is not intended for high-speed data line protection due to its 175pF junction capacitance, which would severely degrade signal integrity on USB 3.x or PCIe lanes. It is specifically designed for 22V power or low-speed control lines (e.g., CC, SBU, enable inputs). For SuperSpeed lines, Semtech recommends RClamp3371ZC (<0.25pF) alongside TDS2211P in complete USB-C solutions.

What PCB layout practices are required to achieve full 40A surge rating for TDS2211P?

To achieve the full 40A (8/20μs) rating, all three GND pins (1, 2, 3) and all three IN pins (4, 5, 6) must be connected in parallel using short, wide traces. Multiple vias to an internal ground plane are mandatory, and placement must be adjacent to the protected connector - minimizing trace inductance that would otherwise elevate clamping voltage during fast transients. Layout guidance is detailed in Figure 7 of the TDS2211P datasheet.

Is TDS2211P compliant with RoHS and halogen-free standards?

Yes - the TDS2211P is Pb-free, halogen-free, and fully compliant with RoHS and WEEE directives. Its molding compound meets UL 94V-0 flammability rating, and lead finish is lead-free. Marking code "T22" and date code appear on the top surface, with a laser dot indicating Pin 1 location per the DFN package drawing in the datasheet.
