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 - 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 voltage stability under 40A surge, DFN-6 thermal and layout constraints, 175pF junction capacitance at 22V, and compatibility with 22V working voltage systems requiring robust EOS resilience beyond standard TVS diodes.
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 breakdown threshold. Unlike conventional TVS diodes, its clamping voltage remains nearly constant due to decreasing RDS(on) under surge - not fixed dynamic resistance.
It delivers 1120W peak pulse power (8/20μs), operates from −40°C to +125°C, and maintains ≤28V clamping up to 40A across temperature. Its 20mΩ dynamic resistance (measured 1–40A, 8/20μs) and 175pF capacitance at 22V support high-speed data line integration where low parasitic impact is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC operating voltage on protected line without leakage or degradation. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs + 1.2/50μs combo wave, RS=2Ω) - ensures downstream ICs (e.g., USB PD controllers) remain below damage thresholds during surge. |
| 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 immunity standards without derating. |
| Junction Capacitance | 175pF at VR=22V, f=1MHz - low enough for USB Type-C VBUS protection without signal integrity compromise. |
| Dynamic Resistance | 20mΩ (1–40A, 8/20μs) - enables flat clamping response and minimizes voltage overshoot during fast-rising transients. |
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 inductance. |
| 4, 5, 6 | IN | Protected line input (e.g., USB PD VBUS); parallel connection ensures uniform current distribution and full 40A rating. |
Key Features
| Feature | Design Value |
|---|---|
| Constant clamping voltage | 27.5–28V across full 1–40A surge range and −40°C to +125°C - eliminates need for over-spec'ing IPP to meet clamping targets. |
| FET-based shunt architecture | Replaces pn-junction TVS with low-RDS(on) MOSFET triggered by precision circuit - reduces thermal stress and improves reliability under repeated surges. |
| Low dynamic resistance | 20mΩ enables minimal voltage rise during fast transients - critical for protecting sensitive 22V-rated load switches and PD controllers. |
| High EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns, 100kHz/5kHz) - sustains operation in noisy industrial environments with repetitive burst noise. |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting 20–22V USB PD VBUS lines against lightning-induced surges and connector ESD events in portable and docking stations. IC Role / Device Role / Timing Role: Transient diverting suppressor placed directly at Type-C connector, shunting surge energy to GND before reaching PD controller or e-fuse. Use Value: Maintains 27.5–28V clamping at 40A and 125°C - prevents controller latch-up or gate oxide damage where conventional TVS would exceed 35V. |
Use Scenario: Safeguarding input of high-side load switches (e.g., HS2950P) in remote meters, robotics, and IoT edge nodes exposed to field surges. IC Role / Device Role / Timing Role: Primary front-end EOS protector on VIN rail, limiting voltage seen by internal FET's drain-source breakdown rating. Use Value: Clamps below 28V while handling 40A - avoids destructive overvoltage on load switch FETs rated for ≤30V VDS, extending system MTBF. |
| IoT Device Power Rail Protection | Storage Device 22V Backup Supply Protection |
Use Scenario: Securing 22V auxiliary rails in battery-backed smart sensors and gateway modules subject to ESD and induced transients in unshielded enclosures. IC Role / Device Role / Timing Role: Single-device solution for 22V rail protection, replacing multi-component TVS+RC networks to reduce BOM count and board area. Use Value: 1.6mm × 1.6mm DFN footprint saves >60% area vs. SOT-23 TVS alternatives - critical for space-constrained IoT PCBs. |
Use Scenario: Protecting 22V backup power inputs in NVMe SSDs and enterprise storage controllers during hot-plug or power sequencing events. IC Role / Device Role / Timing Role: Fast-acting shunt device placed between backup supply and controller power domain to prevent latch-up during voltage overshoot. Use Value: 175pF capacitance at 22V avoids signal distortion on adjacent high-speed traces - unlike higher-capacitance TVS arrays used in legacy designs. |
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), 1000W PPPK, 200pF capacitance. | Limited to lower-energy surges; unsuitable for sustained 40A or high-temp operation where clamping voltage drift exceeds safe margins. | Use only where cost is primary constraint and clamping margin >14V is acceptable. |
| TPD2E001DRYR | Low-capacitance (1.5pF) dual-channel ESD protector; 5.5V working voltage, 12A max IPP, no 22V capability. | Designed for high-speed data lines (USB 2.0, HDMI), not power rail protection - cannot withstand 22V DC or 40A surge. | Select only for signal-line ESD-only scenarios; not a functional alternative for TDS2211P's power rail role. |
Compared with SMAJ22A and TPD2E001DRYR, the TDS2211P uniquely delivers stable 28V clamping at 40A and 125°C in a 1.6mm × 1.6mm package - enabling reliable 22V power rail protection where conventional TVS devices fail to meet both voltage and energy requirements simultaneously.

FAQ
What is the maximum continuous operating voltage for the TDS2211P?
The TDS2211P has a reverse stand-off voltage (VRWM) of 22V, meaning it can continuously block up to 22V DC on the protected line without significant leakage or conduction. This makes it suitable for 20–22V USB PD and industrial power rails where stable DC operation is required alongside transient protection.
How does the TDS2211P achieve constant clamping voltage across surge current?
The TDS2211P uses a surge-rated FET as its main protection element, activated by a precision trigger circuit. As surge current increases, the FET's RDS(on) decreases, maintaining clamping voltage near the trigger circuit's breakdown voltage - resulting in 27.5–28V clamping from 1A to 40A, unlike TVS diodes whose clamping rises linearly with current.
Can the TDS2211P replace a standard TVS diode in a 22V application?
Yes, the TDS2211P is engineered as a drop-in upgrade for 22V TVS applications requiring superior clamping stability. It matches the same working voltage but delivers 40A surge handling and flat 28V clamping - whereas typical 22V TVS diodes clamp above 35V at 40A and degrade with temperature. Layout changes may be needed to accommodate its 6-pin DFN footprint.
What is the recommended PCB layout for optimal surge performance of the TDS2211P?
Place the TDS2211P as close as possible to the protected connector. Connect all three IN pins (4,5,6) via a single short, wide trace to the protected line, and tie all three GND pins (1,2,3) directly to a solid ground plane using multiple vias. Avoid thermal pads - energy is dissipated internally, and minimizing trace inductance is critical for sub-100ns ESD response.
Is the TDS2211P suitable for protecting USB Type-C CC and SBU lines?
No - the TDS2211P is rated for 22V working voltage and optimized for high-energy VBUS protection. For CC/SBU lines, Semtech recommends uClamp2411ZA (24V, low-capacitance), which provides appropriate voltage margin and <0.5pF capacitance. Using TDS2211P on CC/SBU would risk overvoltage damage due to its higher capacitance and lack of signal-line optimization.
