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), and stable 27.5–28V clamping across temperature and current range - deployed in USB Type-C PD bus protection and load switch input safeguarding.
For engineers reviewing the TDS2211P datasheet, pinout, applications, or equivalent options, this device delivers constant clamping voltage under surge stress, low 20mΩ dynamic resistance, 175pF junction capacitance at 22V, DFN 1.6×1.6mm package compatibility, and validated performance in industrial equipment and IoT interface protection.
Technical Context
The TDS2211P uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit when transient voltage exceeds breakdown threshold - enabling near-constant clamping voltage independent of peak pulse current magnitude. Its operation differs fundamentally from conventional TVS diodes by replacing junction-based clamping with low-RDS(on) shunt conduction.
Clamping remains stable from −40°C to +125°C due to minimal temperature dependence of both trigger circuit VBR and FET RDS(on), with measured VC = 27.6–28V at IPP = 40A (1.2/50μs + 8/20μs combination waveform, RS = 2Ω) and dynamic resistance of 20mΩ over 1–40A.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC or RMS operating voltage on protected line without leakage or degradation. |
| Clamping Voltage | 27.5–28V at IPP = 24–40A - ensures downstream ICs (e.g., USB PD controllers) remain below damage thresholds during surge events. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 industrial surge immunity requirements for 22V systems. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds automotive and industrial ESD robustness standards for connector-facing protection. |
| Junction Capacitance | 175pF at VR = 22V, 1MHz - low enough for 22V power rail protection without signal integrity impact on adjacent traces. |
| Dynamic Resistance | 20mΩ - enables flat clamping curve by minimizing IR drop increase as IPP rises from 1A to 40A. |
| Reverse Leakage | 130–600nA at 22V - negligible power loss and thermal loading in always-on 22V bus applications. |
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 handling and minimize parasitic inductance. |
| 4, 5, 6 | IN | Protected line input (e.g., VBUS in USB Type-C); parallel connection of all three pins ensures uniform current sharing and optimal 40A capability. |
Key Features
| Feature | Design Value |
|---|---|
| Constant clamping voltage | 27.5–28V across full 24–40A surge range and −40°C to +125°C - eliminates derating uncertainty in thermal design. |
| FET-based shunt architecture | Replaces PN-junction TVS with <0.1Ω RDS(on) FET - reduces clamping voltage rise vs. current and improves energy dissipation efficiency. |
| Low dynamic resistance | 20mΩ measured between 1A and 40A - ensures minimal voltage overshoot during fast-rising transients (e.g., ESD). |
| High EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns, 5kHz & 100kHz bursts) - protects against repetitive switching noise in industrial motor drives and PLCs. |
| Small-footprint DFN | 1.6mm × 1.6mm area - saves >50% board space versus SO-8 or SOT-23 TVS alternatives while maintaining 40A rating. |

Use Value: Delivers 40A surge handling in compact DFN package - replaces bulkier discrete TVS arrays while maintaining PCB layout simplicity and thermal margin. |
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 VRWM, 35.5V VC @ 17.1A, higher clamping voltage increases with temperature and current. | Lacks constant-clamp behavior; unsuitable where 28V ceiling is critical at high ambient temperatures. | Lower cost but requires derating; use only if clamping >35V is acceptable and thermal margins allow. |
| SP1003-220K | Bi-directional polymer-based TVS; 22V VRWM, ~30V clamping at 20A, slower response (>1ns), higher capacitance (~300pF). | Higher capacitance limits use on high-speed lines; slower turn-on risks overshoot on fast ESD edges. | Acceptable for lower-speed 22V rails where board space allows larger SOD-323 package and 300pF is tolerable. |
Compared with SMAJ22A and SP1003-220K, the TDS2211P provides superior clamping stability, lower dynamic resistance, and smaller footprint - making it the preferred choice for thermally constrained, high-reliability 22V bus protection where consistent sub-28V clamping is mandatory.

FAQ
What is the primary protection function of the TDS2211P?
The TDS2211P functions as a transient diverting suppressor that actively shunts high-energy electrical overstress (EOS) events - including ESD, lightning-induced surges, and EFT - away from sensitive downstream components. Unlike passive TVS diodes, it uses a triggered FET to achieve near-constant clamping voltage. The TDS2211P maintains 27.5–28V clamping across its full 40A surge rating and −40°C to +125°C operating range, making it ideal for protecting 22V power rails in USB PD and industrial systems.
How does the TDS2211P differ from standard TVS diodes in clamping behavior?
The TDS2211P employs a surge-rated FET and precision trigger circuit instead of a PN junction, resulting in clamping voltage that remains nearly constant (27.5–28V) across its entire 24–40A peak pulse current range and full temperature span. In contrast, standard TVS diodes exhibit linear clamping rise (VC = VBR + IPP × RDYN), often exceeding 35V at high current or temperature. This fundamental difference makes the TDS2211P uniquely suited for applications where strict voltage ceilings - such as 28V for USB PD controllers - must be maintained under worst-case surge conditions.
What is the correct PCB layout practice for the TDS2211P to achieve rated 40A performance?
To achieve the full 40A (8/20μs) surge rating, all three IN pins (4, 5, 6) must be connected in parallel 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 within 5mm of the connector or surge entry point to minimize trace inductance. Avoid thermal pads - energy is dissipated in the silicon FET, not the package - and ensure no other high-speed signals run beneath or adjacent to the TDS2211P footprint. These practices are validated in Semtech's layout guidelines for the TDS2211P.
Can the TDS2211P be used for bidirectional signal line protection?
No, the TDS2211P is a unidirectional device intended exclusively for DC power rail or single-ended I/O protection where polarity is fixed (e.g., VBUS, 22V supply inputs). Its electrical characteristics - including reverse stand-off voltage (VRWM = 22V), forward voltage (VF = 0.5V), and pin configuration (IN-to-GND) - confirm it is designed for positive-going transients on a referenced rail. For bidirectional data lines like USB DP/DM or CAN, low-capacitance TVS arrays (e.g., RClamp3371ZC) or dedicated bidirectional suppressors must be used instead of the TDS2211P.
What are the key reliability certifications met by the TDS2211P?
The TDS2211P is certified to IEC 61000-4-2 (±30kV contact/air ESD), IEC 61000-4-4 (±4kV EFT), and IEC 61000-4-5 (40A/8/20μs, ±1kV/1.2/50μs + 8/20μs combination wave). It also complies with RoHS, WEEE, and UL 94V-0 flammability standards. Its DFN package is Pb-free and halogen-free. These certifications are verified in Semtech's official TDS2211P datasheet Rev 2.5 and confirmed through third-party test reports - ensuring the TDS2211P meets industrial and consumer-grade surge immunity requirements without requiring additional external filtering.
