Product details

Overview

TDS2211P from Semtech is a transient diverting suppressor designed for high-energy EOS protection of 22V-rated I/O or power lines, featuring ±30kV IEC 61000-4-2 ESD immunity, 40A (8/20μs) peak pulse current handling, and stable 27.5–28V clamping across temperature and current range-used in USB Type-C PD bus protection and load switch input safeguarding.

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 industrial and portable power delivery systems requiring robust EOS resilience.

Technical Context

The TDS2211P employs 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.

It delivers 1120W peak pulse power (8/20μs), operates from –40°C to +125°C, and maintains ≤28V clamping up to 40A with dynamic resistance of only 20mΩ-enabling reliable protection where thermal drift and voltage overshoot must be minimized in 22V bus architectures.

Key Specifications

Parameter	Value and Actual Design Meaning
Working Voltage	22V - defines maximum continuous DC bus voltage before leakage or conduction onset.
Clamping Voltage	27.5–28V at 40A (8/20μs + 1.2/50μs combo waveform) - ensures protected ICs remain below damage thresholds during worst-case surges.
Peak Pulse Current	40A (8/20μs) - supports compliance with IEC 61000-4-5 ±1kV (RS = 42Ω) industrial surge testing.
ESD Withstand	±30kV contact & air per IEC 61000-4-2 - eliminates need for secondary ESD stages in USB-C and IoT interfaces.
Junction Capacitance	175pF at VR = 22V, 1MHz - low enough for 22V power rail protection without signal integrity impact.
Dynamic Resistance	20mΩ (measured 1A–40A, 8/20μs) - enables flat clamping curve and minimal V_C rise with increasing surge magnitude.

Pinout & Package

Package: DFN 1.6mm × 1.6mm × 0.55mm, 6-lead, Pb-free, RoHS/WEEE compliant, UL 94V-0 molding compound.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3	GND	Common ground return path for surge current; all three pins must be connected to maximize current sharing and minimize parasitic inductance.
4, 5, 6	IN	Protected line input (e.g., VBUS or power rail); parallel connection of all three pins ensures full 40A rating and uniform current distribution.

Key Features

Feature	Design Value
FET-based clamping architecture	Delivers near-constant 27.5–28V clamping from 1A to 40A, eliminating voltage overshoot common in TVS diodes.
Temperature-stable clamping	Clamping voltage variation <0.5V across –40°C to +125°C - enables predictable protection in automotive and industrial ambient conditions.
High-energy surge capability	1120W peak pulse power rating supports repeated 40A transients without degradation or thermal runaway.
Low dynamic resistance	20mΩ R_DYN minimizes IR drop during surge, preserving voltage margin for downstream 22V-rated controllers and switches.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SMAJ22A	Standard unidirectional TVS diode; clamping rises to ~42V at 40A (8/20μs); higher dynamic resistance (~0.5Ω).	Limited to lower-temperature, lower-current applications where clamping voltage margin allows >14V overhead.	Choose SMAJ22A only if cost is primary concern and system can tolerate higher clamping voltage and thermal derating.
SP1003-02HTG	Bi-directional TVS array; 22V working voltage; clamps at ~36V @ 40A; 25pF typical capacitance per line.	Better suited for differential data lines (e.g., RS-485), not optimized for high-current single-rail power protection.	Select SP1003-02HTG when protecting multiple low-voltage signal pairs-not for 22V bus-level surge diversion.

Compared with SMAJ22A and SP1003-02HTG, the TDS2211P uniquely combines 20mΩ dynamic resistance, 27.5–28V flat clamping, and 40A surge rating in a 1.6mm × 1.6mm package-making it the only option capable of protecting 22V power rails under simultaneous high-current and high-temperature stress without voltage margin compromise.

FAQ

What is the primary protection function of the TDS2211P?

The TDS2211P functions as a transient diverting suppressor that uses a surge-rated FET and precision trigger circuit to clamp EOS events on 22V-rated lines. Unlike TVS diodes, it maintains a stable 27.5–28V clamping voltage across its full 40A (8/20μs) surge rating and –40°C to +125°C operating range-ensuring consistent protection for USB-C PD controllers and industrial load switches.

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

The TDS2211P achieves near-constant clamping voltage because its shunt FET's R_DS(on) decreases under surge, counteracting current increase-whereas standard TVS diodes follow VC = VBR + IPP × R_DYN, causing linear clamping rise. At 40A and 125°C, TDS2211P clamps at ~27.6V versus ~38V for a typical 22V TVS, directly improving system voltage margin and reliability.

What is the correct PCB layout practice for the TDS2211P?

All three IN pins (4, 5, 6) must be shorted together via a single low-inductance trace to the protected line, and all three GND pins (1, 2, 3) must connect to a solid ground plane using multiple vias. The device must be placed adjacent to the connector-within 5mm-to minimize trace inductance and prevent coupling into adjacent nets during fast ESD events, as confirmed in Semtech's layout guidelines.

Can the TDS2211P be used for bidirectional signal line protection?

No-the TDS2211P is a unidirectional device intended for single-rail power or I/O line protection (e.g., VBUS, load switch input). Its electrical characteristics-including reverse stand-off voltage (22V), breakdown (25–27.9V), and forward voltage (0.5V)-are specified only for anode-to-cathode polarity. For bidirectional data lines like USB SS or DP/DM, low-capacitance TVS arrays such as RClamp3371ZC are required instead of the TDS2211P.

What is the maximum junction temperature and thermal derating behavior of the TDS2211P?

The TDS2211P has a junction temperature range of –55°C to +150°C and operates continuously from –40°C to +125°C. Its clamping voltage remains stable (<0.5V variation) across this full range, and peak pulse current rating does not require thermal derating-unlike TVS diodes whose IPP drops significantly above 85°C. This makes the TDS2211P uniquely suitable for thermally constrained industrial and automotive under-hood applications.
