Product details

Overview

TDS2211P from Semtech is a transient diverting suppressor designed for high-energy EOS protection of 22V voltage buses 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 - deployed in USB Type-C PD input protection and industrial load switch front-end circuits.

For engineers reviewing the TDS2211P datasheet, pinout, applications, or equivalent options, key selection criteria include clamping stability across temperature and current, low dynamic resistance for flat VC vs. IPP behavior, DFN-6 package layout constraints, and compatibility with 22V working voltage systems requiring robust surge immunity per IEC 61000-4-5.

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 V_BR (~27.9V typ). Unlike conventional TVS diodes, its clamping voltage remains nearly constant (27.5–28V) from 24A to 40A due to decreasing R_DS(on) under surge conditions.

It operates over –40°C to +125°C with stable junction capacitance (175pF @ 22V, 1MHz) and reverse leakage (<600nA @ 22V), and integrates six terminals: three parallel IN pins (4–6) and three parallel GND pins (1–3) to minimize parasitic inductance and maximize surge current handling in compact DFN 1.6×1.6×0.55mm.

Key Specifications

Parameter	Value and Actual Design Meaning
Working Voltage (V_RWM)	22V - defines maximum continuous DC or RMS operating voltage on protected line without leakage or conduction.
Clamping Voltage (V_C)	27.5–28V at 40A (8/20μs) - ensures downstream 24V-rated ICs (e.g., USB PD controllers) remain below damage threshold during surge events.
Peak Pulse Current (I_PP)	40A (8/20μs) - supports compliance with IEC 61000-4-5 Level 4 (±1kV, RS=42Ω) on unsymmetrical lines.
Dynamic Resistance (R_DYN)	20mΩ - enables flat clamping response; reduces V_C rise vs. I_PP compared to TVS diodes with fixed R_DYN.
Junction Capacitance (C_J)	175pF @ 22V, 1MHz - low enough for 22V power rail protection without signal integrity impact on adjacent traces.
ESD Withstand	±30kV contact & air (IEC 61000-4-2) - exceeds industrial and consumer ESD immunity requirements for connector-facing protection.

Pinout & Package

Package: DFN 1.6mm × 1.6mm × 0.55mm, 6-lead, Pb-free, RoHS/WEEE compliant, UL 94V-0 molding compound, marked "T22" + date code.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3	GND	Parallel ground terminals - must all be connected to low-inductance ground plane via multiple vias to sustain 40A surge current and minimize V_GS noise coupling.
4, 5, 6	IN	Parallel input terminals - connect directly to protected bus (e.g., V_Bus in USB-C); all three required for full 40A rating and optimal thermal/current sharing.

Key Features

Feature	Design Value
Constant clamping voltage across I_PP	27.5–28V from 24A to 40A - eliminates need to overspecify I_PP to meet V_C limits, simplifying system-level surge margining.
Stable clamping over temperature	V_C variation <0.5V from –40°C to +125°C - enables reliable protection in automotive-grade or industrial ambient environments without derating.
Low dynamic resistance	20mΩ - minimizes IR drop during surge, preserving voltage headroom for downstream 24V-rated components.
High EFT immunity	±4kV (5/50ns, 100kHz/5kHz, IEC 61000-4-4) - protects against repetitive fast transients in motor drives, PLCs, and switching power supplies.

Applications

USB Type-C Power Delivery Input Protection	Industrial Load Switch Input Protection
Use Scenario: Protecting V_Bus lines in USB-C receptacles supporting up to 20V/5A PD, exposed to ESD and lightning-induced surges. IC Role / Device Role / Timing Role: Primary front-end surge diverter placed between connector and load switch or PD controller. Use Value: Maintains 27.5–28V clamping at 40A - keeps voltage below 30V damage threshold of common USB PD controllers (e.g., STUSB4500, CYPD3177) even at 125°C.

Use Scenario: Securing 22V auxiliary power inputs in battery-backed IoT gateways subjected to field ESD and induced surges from nearby AC wiring. IC Role / Device Role / Timing Role: Single-component, space-efficient EOS suppressor replacing multi-diode TVS arrays on compact PCBs. Use Value: 1.6×1.6mm DFN footprint saves >60% board area vs. SO-8 TVS solutions while delivering superior clamping consistency and thermal stability.	Use Scenario: Safeguarding 22V backup power rails in NVMe SSD enclosures and enterprise storage controllers exposed to hot-plug transients and chassis ESD. IC Role / Device Role / Timing Role: Low-capacitance (175pF), high-power surge clamp on main power input before PMIC or buck converter. Use Value: 175pF capacitance avoids resonance with typical 10–100μF bulk capacitors; 40A rating handles worst-case hot-swap energy without degradation.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
Semtech TDS2411P	24V V_RWM, 28.5V V_C @ 40A, same DFN-6 package and FET-based architecture.	Targeted for 24V systems (e.g., PoE++, industrial 24V rails); slightly higher clamping than TDS2211P.	Select TDS2411P when protecting 24V nominal buses where 22V V_RWM would cause excessive leakage or premature conduction.
Littelfuse SP3022-01ETG	22V V_RWM, 33V V_C @ 20A (8/20μs), 350pF capacitance, SOD-323 package.	Lower I_PP rating and higher V_C; suited for lower-energy data-line protection, not power-rail surge diversion.	Use SP3022-01ETG only for low-current signal lines (e.g., CC/SBU in USB-C); not suitable for 40A V_Bus protection where TDS2211P's flat clamping is critical.

Compared with TDS2411P and SP3022-01ETG, the TDS2211P uniquely delivers 22V-rated clamping stability at 40A with 20mΩ R_DYN, making it the only option among the three qualified for high-current, thermally demanding 22V power rail protection in USB PD and industrial e-fuse applications.

FAQ

What is the maximum continuous operating voltage for the TDS2211P?

The TDS2211P has a reverse stand-off voltage (V_RWM) of 22V, meaning it can continuously block up to 22V DC or RMS without significant leakage or conduction. This makes it suitable for 22V nominal power rails such as USB-C PD V_Bus and industrial 24V systems with margin. Exceeding 22V risks increased leakage and potential activation during normal operation.

How does the TDS2211P achieve constant clamping voltage across varying surge currents?

The TDS2211P achieves constant clamping by using a surge-rated FET as the primary shunt element. When triggered, the FET's R_DS(on) decreases with increasing current, counteracting the linear V = I × R rise seen in TVS diodes. As a result, the TDS2211P maintains 27.5–28V clamping from 24A to 40A - a key advantage confirmed in its datasheet Figure 3 and electrical characteristics table.

Can the TDS2211P replace a standard TVS diode in a 22V application?

Yes, the TDS2211P can replace a standard TVS diode in 22V applications - but only if the design requires superior clamping stability, higher peak current (40A), or operation across wide temperature ranges. Its DFN-6 footprint and parallel-pin layout differ from common SMB/SMA packages, so PCB layout and grounding must follow Semtech's guidelines to realize the full 40A capability of the TDS2211P.

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

Semtech specifies that all three IN pins (4–6) and all three GND pins (1–3) must be connected - IN pins via a single low-inductance trace to the protected line, and GND pins via multiple vias to an unbroken ground plane. The TDS2211P must be placed within 5mm of the connector. Deviating from this layout degrades surge handling and may reduce the effective I_PP rating below 40A.

Is the TDS2211P suitable for protecting high-speed data lines like USB SuperSpeed?

No, the TDS2211P is not suitable for USB SuperSpeed (SS) differential pairs due to its 175pF junction capacitance, which would distort signal integrity. It is intended for power rail or low-speed control line protection (e.g., V_Bus, CC, SBU). For SS lanes, Semtech recommends low-capacitance devices like RClamp3371ZC (<0.25pF), as specified in the TDS2211P application note.
