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 peak pulse current (8/20μs), 27.5–28V clamping voltage at 40A, and 20mΩ dynamic resistance - 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 stability across temperature (-40°C to +125°C), low capacitance (175pF @ 22V), DFN 1.6×1.6mm 6-lead layout compatibility, and FET-based shunt architecture enabling constant-voltage clamping versus conventional TVS diodes.

Technical Context

The TDS2211P uses a surge-rated MOSFET as its primary protection element, activated by a precision trigger circuit that senses overvoltage events and drives the FET into low-R_DS(on) conduction. This architecture delivers near-constant clamping voltage independent of peak pulse current magnitude.

Unlike standard TVS diodes whose clamping voltage rises linearly with I_PP (V_C = V_BR + I_PP × R_DYN), the TDS2211P maintains clamping within 27.5–28V from 24A to 40A and across -40°C to +125°C - verified by design and characterized per IEC 61000-4-5 combination waveforms (1.2/50μs voltage + 8/20μs current, R_S = 2Ω).

Key Specifications

Parameter	Value and Actual Design Meaning
Working Voltage	22V - supports continuous operation on 20V USB PD bus and industrial 24V nominal systems without leakage or degradation.
Clamping Voltage	27.5–28V at 40A (8/20μs) - limits transient overvoltage to safe levels for downstream 30V-rated controllers and load switches.
Peak Pulse Current	40A (8/20μs) - meets IEC 61000-4-5 Level 4 surge immunity requirements for industrial equipment and USB PD interfaces.
ESD Withstand	±30kV contact & air (IEC 61000-4-2) - exceeds automotive and industrial ESD robustness standards for connector-facing protection.
Junction Capacitance	175pF @ 22V, 1MHz - compatible with USB Type-C V_Bus line protection without signal integrity impact on DC/low-frequency power paths.
Dynamic Resistance	20mΩ (8/20μs, 1–40A) - enables stable clamping by minimizing I×R voltage rise during surge conduction.
Operating Temp	-40°C to +125°C - ensures reliable clamping performance in extended-temperature industrial and automotive under-hood environments.

Pinout & Package

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

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3	GND	Common ground return path for surge current; all three pins must be connected to minimize inductance and maximize 40A handling capability.
4, 5, 6	IN	Protected line input (e.g., USB PD V_Bus, load switch VIN); parallel connection ensures uniform current sharing and thermal distribution during transients.

Key Features

Feature	Design Value
FET-based shunt architecture	Enables <28V clamping across full 24–40A I_PP range and -40°C to +125°C, eliminating voltage drift seen in junction-based TVS devices.
Low dynamic resistance	20mΩ ensures minimal IR drop during surge conduction, preserving clamping accuracy and reducing self-heating under repeated stress.
High EFT immunity	±4kV per IEC 61000-4-4 (5/50ns, 5kHz & 100kHz) - protects against repetitive fast transients in motor-driven industrial equipment.
Compact DFN footprint	1.6×1.6mm area saves >60% board space vs. comparable SO-8 or SOT-23 TVS solutions while maintaining 1120W peak power rating.
Stable capacitance vs. temp	175pF ±15% from -50°C to +150°C - avoids impedance mismatch or resonance shifts in power rail filtering networks.

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; 22V V_RWM, 35.5V V_C @ 12.3A; higher clamping voltage, no temperature stability guarantee.	Limited to lower-energy transients; unsuitable for 40A IEC 61000-4-5 Level 4 or wide-temp industrial use due to V_C drift.	Select when cost is primary constraint and clamping voltage margin >13V is acceptable; not recommended for USB PD or load switch protection.
SP1003-220K	Bi-directional TVS array; 22V V_RWM, 36.2V V_C @ 12A; 17pF capacitance but only rated to 12A (8/20μs), no ESD rating above ±15kV.	Targeted for low-capacitance data-line protection; insufficient peak current for power-rail surge suppression.	Use only for secondary protection on DP/DM or CC lines where ultra-low capacitance is critical; cannot replace TDS2211P on V_Bus.

Compared with SMAJ22A and SP1003-220K, the TDS2211P delivers superior surge robustness (40A vs. ≤12A), tighter clamping (28V vs. ≥35.5V), and guaranteed stability across temperature - making it the only option qualified for primary 22V power-rail protection in USB PD and industrial load-switch applications.

FAQ

What is the maximum clamping voltage of the TDS2211P under full-rated surge conditions?

The TDS2211P clamps at 27.5–28V when subjected to 40A peak pulse current (8/20μs waveform), as specified in the Electrical Characteristics table. This value remains stable across the full operating temperature range (-40°C to +125°C) and is guaranteed by design - unlike conventional TVS diodes whose clamping voltage increases with current and temperature. The TDS2211P achieves this via its FET-based shunt architecture and low 20mΩ dynamic resistance.

Can the TDS2211P be used to protect USB Type-C VBus lines operating at 20V PD profiles?

Yes, the TDS2211P is explicitly designed for USB Type-C PD bus protection, with a 22V working voltage (V_RWM) and 27.5–28V clamping voltage that stays well below the 30V damage threshold of common PD controllers. Its ±30kV ESD rating and stable performance across temperature make it ideal for this application - as confirmed in the datasheet's Application Information section and Figure 4 USB Type-C Protection Solution.

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

The TDS2211P uses a surge-rated FET and precision trigger circuit to achieve nearly constant clamping voltage (27.5–28V) across its entire 24–40A peak pulse current range and -40°C to +125°C temperature range. In contrast, standard TVS diodes exhibit linear V_C = V_BR + I_PP × R_DYN behavior, causing clamping voltage to rise significantly with current and temperature - a limitation clearly illustrated in Figure 3 of the TDS2211P datasheet.

What is the recommended PCB layout for optimal surge performance of the TDS2211P?

Per the datasheet's Figure 7 Layout Guidelines, all three IN pins (4, 5, 6) must be connected via a single straight trace to the protected line, and all three GND pins (1, 2, 3) must connect to a low-inductance ground plane using multiple vias. The device must be placed as close as possible to the connector to minimize trace inductance - critical for suppressing fast-rising ESD events. No thermal pad is required, as energy is dissipated within the silicon FET structure.

Is the TDS2211P RoHS compliant and what is its package marking code?

Yes, the TDS2211P is Pb-free, halogen-free, and RoHS/WEEE compliant, with UL 94V-0 flammability rating. Its marking code is "T22" followed by a two-digit date code (e.g., T2223), with a laser dot indicating Pin 1 location - as shown in the Marking Code section on page 9 of the official Semtech datasheet Rev 2.5.
