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 voltage 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 performance, low 175pF junction capacitance at 22V, and compatibility with 22V working voltage systems requiring robust EOS resilience without TVS-like voltage drift.
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 - enabling near-constant clamping via ultra-low dynamic resistance (20mΩ). Unlike conventional TVS diodes, its clamping voltage remains stable across 24–40A and −40°C to +125°C due to decreasing RDS(on) under surge.
It operates as a bidirectional shunt device with three parallel input terminals (pins 4–6) and three ground terminals (pins 1–3), optimized for low-inductance PCB layout adjacent to connectors. The functional architecture decouples trigger threshold (≈27V VBR) from conduction path, eliminating linear VC = VBR + IPP × RDYN dependency.
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 40A (8/20μs + 1.2/50μs combo wave, RS=2Ω) - ensures downstream 24V-rated ICs (e.g., USB PD controllers) remain below damage threshold during surge. |
| Peak Pulse Current | 40A (8/20μs) - supports compliance with IEC 61000-4-5 Level 4 (±1kV, RS=42Ω, CS=0.5μF) on unsymmetrical lines. |
| ESD Withstand | ±30kV contact & air per IEC 61000-4-2 - exceeds automotive and industrial ESD immunity requirements without derating. |
| Junction Capacitance | 175pF at VR=22V, f=1MHz - low enough for 22V power rail protection without signal integrity impact on moderate-speed buses. |
| Dynamic Resistance | 20mΩ (measured 1–40A, 8/20μs) - enables flat clamping curve and minimizes IR drop during high-current transients. |
Pinout & Package
Package: DFN-6 (1.6mm × 1.6mm × 0.55mm), Pb-free, RoHS/WEEE compliant, UL 94V-0 molding compound, tape-and-reel (3,000 pcs/reel).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground return path for surge current; all three must be connected with low-inductance vias to maximize 40A capability. |
| Pins 4, 5, 6 | IN | Parallel-connected input terminals for protected line (e.g., VBUS); shared connection required for full surge rating and thermal distribution. |
Key Features
| Feature | Design Value |
|---|---|
| FET-based shunt architecture | Enables constant clamping voltage independent of peak pulse current magnitude or ambient temperature - eliminates TVS-style VC drift. |
| Ultra-low dynamic resistance | 20mΩ ensures minimal voltage overshoot during fast-rising surges and reduces localized heating under repeated 40A events. |
| Triple-terminal input & ground | Distributes surge current across 3 pins each, lowering current density and parasitic inductance versus single-pin alternatives. |
| Stable 175pF capacitance | Maintains predictable filtering behavior across −40°C to +125°C, critical for consistent EMC performance in wide-temperature deployments. |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting 20–22V VBUS lines in USB-C PD ports against lightning-induced surges and connector ESD events. IC Role / Device Role / Timing Role: Primary shunt suppressor placed directly at connector, clamping transients before they reach PD controller or e-fuse. Use Value: Maintains 27.5–28V clamping across 40A and −40°C to +125°C - prevents false OVP trips and ensures PD controller survival where TVS devices exceed safe voltage thresholds. |
Use Scenario: Safeguarding input pins of industrial-grade load switches (e.g., HS2950P) exposed to field wiring transients in robotics or remote meters. IC Role / Device Role / Timing Role: Front-end EOS guard that limits voltage seen by internal FET gate oxide and overvoltage protection circuitry. Use Value: Clamps below 28V even at 125°C - avoids permanent damage to load switch's 30V absolute max rating while sustaining 40A surge energy dissipation. |
| IoT Device Power Rail Protection | Storage Device 22V Backup Supply Protection |
Use Scenario: Securing 22V auxiliary rails in battery-backed IoT gateways subjected to EFT bursts and cable discharge events. IC Role / Device Role / Timing Role: Low-capacitance, high-energy suppressor on main power input, co-located with input capacitor. Use Value: Delivers ±4kV EFT immunity per IEC 61000-4-4 without degrading startup timing or causing brownout due to excessive leakage (<600nA at 22V). |
Use Scenario: Protecting 22V backup supplies in NVMe SSDs or enterprise storage controllers from hot-plug transients and board-level ESD. IC Role / Device Role / Timing Role: Standby-mode protector with <600nA reverse leakage at 22V - preserves battery life while maintaining readiness for surge response. Use Value: 175pF capacitance avoids resonance with bulk input capacitors, ensuring stable regulation during transient recovery without oscillation. |
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); higher dynamic resistance (~0.5Ω); no temperature-stable clamping. | Limited to lower-energy surges; requires derating above 85°C; unsuitable for 22V systems with tight clamping margins. | Select only if cost sensitivity outweighs clamping stability and temperature performance requirements. |
| SP1003-220 | Bi-directional polymer ESD suppressor; rated for ±30kV ESD but only 5A (8/20μs); clamping >50V at rated current; no IEC 61000-4-5 surge rating. | Applicable only to ESD-only scenarios; cannot handle lightning-level surges or repetitive EFT stress. | Use solely for handheld consumer interfaces where 40A surge immunity is not required. |
Compared with SMAJ22A and SP1003-220, the TDS2211P uniquely delivers 40A surge capability with flat 27.5–28V clamping across full temperature and current range - making it the only option among the three qualified for industrial 22V bus protection meeting IEC 61000-4-5 Level 4 and sustained EFT stress.

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 withstand up to 22V DC or RMS on its input terminals without significant leakage or degradation. This makes it suitable for nominal 20V USB PD VBUS and other 22V-rated power rails where long-term reliability under steady-state bias is required.
How does the TDS2211P achieve stable clamping voltage across temperature and current?
The TDS2211P achieves stable clamping by using a surge-rated FET as the conduction element, activated by a precision trigger circuit. As surge current increases, the FET's RDS(on) decreases, counteracting voltage rise - resulting in a nearly constant 27.5–28V clamping level from −40°C to +125°C and 24A to 40A. This differs fundamentally from TVS diodes, whose clamping rises linearly with current and temperature.
Can the TDS2211P be used for bidirectional signal line protection?
No - the TDS2211P is designed exclusively for unidirectional power or I/O line protection (e.g., VBUS, load switch input). Its pin configuration (IN pins 4–6, GND pins 1–3) and internal architecture do not support symmetric bidirectional clamping like dedicated data-line TVS arrays. For DP/DM or CC lines, Semtech recommends RClamp3371ZC or uClamp2411ZA instead of the TDS2211P.
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 (4–6) via a single short, wide trace to the protected line, and tie all three GND pins (1–3) directly to a solid ground plane using multiple low-inductance vias. Avoid thermal pads - energy is dissipated internally, and excessive copper under the package can impede heat spreading across the die surface.
Does the TDS2211P require external bias or control signals to operate?
No - the TDS2211P is fully autonomous and requires no external power, enable signals, or configuration. It operates passively: the integrated trigger circuit senses overvoltage conditions and automatically activates the shunt FET within nanoseconds. This makes the TDS2211P ideal for "set-and-forget" protection in space-constrained, high-reliability applications where system-level control is unavailable or undesirable.
