Product details
Overview
TDS2211P from Semtech is a transient diverting suppressor (TDS) designed for high-energy EOS protection of 22V DC 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, 20mΩ dynamic resistance, and 175pF junction capacitance - deployed in USB PD, USB Type-C, and industrial load switch input protection.
For engineers reviewing the TDS2211P datasheet, pinout, applications, or equivalent options, this device delivers stable clamping across temperature (−40°C to +125°C) and current (24–40A), enabling robust overvoltage protection where conventional TVS diodes exhibit rising VC with IPP and temperature.
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 FET when transient voltage exceeds VBR (~27.9V typ). Unlike standard TVS diodes, its clamping voltage remains nearly constant due to the FET's low RDS(on) (<0.1Ω), not fixed RDYN.
It operates as a single-line protector with bidirectional capability between IN (pins 4–6) and GND (pins 1–3), supports combination-wave surge testing (1.2/50μs voltage + 8/20μs current, RS = 2Ω), and maintains <600nA reverse leakage at 22V across −40°C to +125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V VRWM - defines maximum continuous DC bus voltage before activation. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs + 1.2/50μs combo wave) - ensures protected ICs (e.g., USB PD controllers) stay below damage thresholds. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 surge immunity for industrial equipment. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds automotive and industrial ESD requirements without external shielding. |
| Dynamic Resistance | 20mΩ - enables flat clamping curve; VC rise ≤0.4V from 24A to 40A, unlike TVS diodes with linear VC = VBR + IPP×RDYN. |
| Junction Capacitance | 175pF at 22V, 1MHz - compatible with 22V power rails but not high-speed data lines (requires separate low-C TVS like RClamp3371ZC). |
Pinout & Package
Package: DFN 1.6mm × 1.6mm × 0.55mm, 6-lead, RoHS-compliant, UL 94V-0 molding compound, lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground return path; all three must be connected to maximize surge current handling and minimize parasitic inductance. |
| Pins 4, 5, 6 | IN | Protected line input (bidirectional); all three pins connect in parallel to the same bus node for lowest impedance path during transients. |
Key Features
| Feature | Design Value |
|---|---|
| Constant clamping across IPP range | VC varies only 0.5V from 24A to 40A - eliminates derating for higher surge currents in industrial designs. |
| Stable clamping over temperature | VC remains ~27.6V from −40°C to +125°C - avoids thermal runaway risk seen in silicon TVS diodes. |
| Low dynamic resistance | 20mΩ enables sub-1V IR drop at 40A - critical for protecting low-voltage-tolerance load switches (e.g., HS2950P). |
| High-energy EOS protection | 1120W peak pulse power (8/20μs) - handles lightning-induced surges exceeding IEC 61000-4-5 Class 4. |
Applications
| USB Type-C Power Delivery Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting 20–22V VBUS lines in USB-C PD ports against ESD, lightning surges, and hot-plug transients. IC Role / Device Role / Timing Role: Primary overvoltage clamp placed between connector and PD controller or buck converter input. Use Value: Maintains 27.6V clamping at 40A and 125°C - prevents damage to PD controllers rated for ≤28V absolute max. |
Use Scenario: Safeguarding enable or input pins of industrial-grade load switches (e.g., HS2950P) exposed to field wiring surges. IC Role / Device Role / Timing Role: Front-end transient shunt that diverts energy before it reaches the switch's internal FET gate or drain. Use Value: Limits voltage stress on load switch RDS(on) and OVP circuitry, extending reliability in remote meters and robotics. |

Use Scenario: Protecting 22V supply rails in NVMe SSD enclosures or enterprise storage backplanes from hot-swap and system-level surges. IC Role / Device Role / Timing Role: High-reliability clamping element co-located with power entry connectors to minimize PCB trace inductance. Use Value: 40A surge rating and −40°C to +125°C operation ensure compliance with MIL-STD-810G and Telcordia GR-1089-CORE surge requirements. |
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 silicon TVS diode; 22V VRWM, 35.5V VC @ 12.3A, 1.5Ω RDYN - clamping rises to ~42V at 40A and increases with temperature. | Limited to lower-energy transients; requires larger derating margin for industrial 40A surges and high-temperature environments. | Choose SMAJ22A only if cost sensitivity outweighs clamping stability and thermal performance requirements. |
| TPD2E001DRYR | Low-capacitance (1.5pF) dual-channel ESD protector; 22V VRWM, 28V VC @ 1A - rated only for 4A IPP, no IEC 61000-4-5 surge capability. | Designed for high-speed data lines (e.g., USB 2.0 D+/D−), not power rail protection; insufficient for 40A surge events. | Use TPD2E001DRYR for DP/DM line ESD protection alongside TDS2211P - not as a functional replacement. |
Compared with SMAJ22A and TPD2E001DRYR, the TDS2211P uniquely combines 40A surge rating, temperature-stable 27.6V clamping, and 20mΩ dynamic resistance - making it the only option qualified for 22V power rail protection in USB PD, industrial load switches, and high-reliability storage systems.

FAQ
What is the clamping voltage of TDS2211P at 40A surge current?
The TDS2211P clamps at 27.6–28V under IEC 61000-4-5 combination-wave conditions (1.2/50μs voltage + 8/20μs current, RS = 2Ω) at 40A. This value is guaranteed across −40°C to +125°C and reflects the device's FET-based architecture, which maintains near-constant VC independent of IPP - unlike standard TVS diodes whose clamping rises linearly with current.
Can TDS2211P be used for bidirectional signal line protection?
No - the TDS2211P is designed exclusively for unidirectional 22V DC power or I/O line protection. Its internal architecture connects pins 4–6 (IN) to pins 1–3 (GND) in a single shunt path. For bidirectional data lines (e.g., USB 2.0, DP/DM), low-capacitance TVS devices such as RClamp3371ZC must be used alongside TDS2211P in a hybrid protection scheme.
Does TDS2211P require a thermal pad on the PCB?
No - the TDS2211P dissipates surge energy primarily through conduction, not junction heating, and does not require a thermal pad. The datasheet explicitly states "no thermal pad is needed." Instead, design focus should be on low-inductance grounding: connect all three GND pins (1–3) directly to a solid ground plane using multiple vias, and place the device within 5mm of the protected connector.
How does TDS2211P compare to standard TVS diodes in temperature stability?
The TDS2211P maintains a clamping voltage of ~27.6V from −40°C to +125°C, whereas standard TVS diodes (e.g., SMAJ22A) exhibit increasing VC with temperature due to positive TC of VBR and fixed RDYN. At 125°C, SMAJ22A clamping can exceed 42V at 40A - risking damage to 28V-max components - while TDS2211P remains within specification.
Is TDS2211P RoHS and REACH compliant?
Yes - the TDS2211P is Pb-free, halogen-free, and fully compliant with RoHS Directive 2011/65/EU and WEEE Directive 2012/19/EU. Its molding compound meets UL 94V-0 flammability rating, and the lead finish is lead-free per J-STD-609. Full compliance documentation is available from Semtech upon request.
