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 (8/20μs) peak pulse current handling, and stable 27.5–28V clamping across temperature and current range; used in USB Type-C PD input protection and load switch front-end surge suppression.
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, 22V working voltage compliance, and compatibility with industrial and USB PD system-level surge standards (IEC 61000-4-5 ±1kV).
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-dynamic resistance is only 20 mΩ at 8/20μs.
It operates over –40°C to +125°C with <600 nA reverse leakage at 22V and 175 pF junction capacitance at 22V/1MHz. The device delivers 1120W peak pulse power and maintains stable clamping (27.5–28V) at both 24A and 40A combination-wave surges (1.2/50μs voltage + 8/20μs current, RS = 2Ω).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22 V - matches nominal USB PD bus and industrial 24V rail systems without derating. |
| Clamping Voltage | 27.5–28 V at 40A - stays below 30V damage threshold of common load switches and USB PD controllers. |
| Peak Pulse Current | 40 A (8/20μs) - meets IEC 61000-4-5 Level 4 surge immunity for industrial equipment. |
| ESD Withstand | ±30 kV contact & air (IEC 61000-4-2) - exceeds automotive and consumer interface ESD requirements. |
| Dynamic Resistance | 20 mΩ - enables low-voltage drop during surge conduction, minimizing energy dissipation in silicon. |
| Junction Capacitance | 175 pF at 22V/1MHz - suitable for DC power and low-speed signal line protection, not high-speed data lanes. |
Pinout & Package
Package: DFN-6 (1.6 mm × 1.6 mm × 0.55 mm), RoHS-compliant, Pb-free, UL 94V-0 molding compound, tape-and-reel packaging (3,000 pcs/reel).
| 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 parasitic inductance. |
| 4, 5, 6 | IN | Protected line input (bus or I/O); parallel connection ensures uniform current distribution and full 40A rating. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies ≤0.5 V from 24A to 40A surge - eliminates design margin inflation needed with TVS diodes. |
| FET-based shunt topology | Surge energy diverted through low-RDS(on) channel instead of PN-junction - avoids thermal runaway at high ambient temperatures. |
| Temperature-stable clamping | Clamps at 27.5–28 V from –40°C to +125°C - enables reliable protection in uncontrolled industrial environments. |
| High EFT immunity | Withstands ±4 kV per IEC 61000-4-4 (5/50 ns, 5 kHz & 100 kHz bursts) - protects against switching noise in motor drives and PLCs. |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting VBus lines in USB-C receptacles supporting up to 20V/5A PD negotiation. IC Role / Device Role / Timing Role: Primary EOS shunt suppressor placed between connector and PD controller or load switch input.

Use Value: Absorbs 40A/8/20μs transients without degrading regulation or triggering overvoltage shutdown in sensitive storage controllers. |
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 ~42 V at 40A; 10× higher dynamic resistance (~200 mΩ). | Limited to lower-temperature or lower-current scenarios where clamping margin allows >35 V. | Choose SMAJ22A only if board space permits larger SMA package and system can tolerate higher clamping voltage. |
| TPD2E001DRYR | Low-capacitance (12 pF) dual-channel TVS; rated for 3A (8/20μs); no 22V working voltage rating. | Designed for high-speed data lines (USB 2.0, I²C), not power rail protection. | TPD2E001DRYR is unsuitable for TDS2211P's 40A/22V power-line role; use only for signal-line ESD, not EOS. |
Compared with SMAJ22A and TPD2E001DRYR, the TDS2211P uniquely delivers stable sub-28V clamping at 40A while operating across –40°C to +125°C-making it the only option among the three qualified for industrial-grade 22V bus protection with minimal design margin overhead.

FAQ
What is the maximum clamping voltage of the TDS2211P at 40A surge current?
The TDS2211P clamps at 27.5–28 V under 40A (8/20μs) peak pulse current with a 1.2/50μs voltage + 8/20μs current combination waveform and 2Ω source impedance. This value is guaranteed across –40°C to +125°C and reflects the device's FET-based constant-clamp behavior-not a rising curve like standard TVS diodes. The TDS2211P achieves this via ultra-low dynamic resistance (20 mΩ), ensuring predictable protection margins in TDS2211P deployments.
Can the TDS2211P be used to protect USB 3.2 SuperSpeed differential pairs?
No-the TDS2211P is not suitable for USB 3.2 SuperSpeed (5+ Gbps) data lines due to its 175 pF junction capacitance at 22V, which would severely degrade signal integrity. It is explicitly intended for DC power rails or low-speed control lines (e.g., CC, SBU, VBus). For SuperSpeed protection, Semtech recommends low-capacitance devices like RClamp3371ZC (<0.25 pF); the TDS2211P serves only the power-domain role in full USB-C protection schemes.
Does the TDS2211P require a thermal pad or heatsink on the PCB?
No-unlike power MOSFETs or linear regulators, the TDS2211P does not require a thermal pad or external heatsink. Its FET-based architecture dissipates surge energy efficiently during transient events, and the DFN-6 package is rated for full 40A operation without additional thermal relief. Layout best practice emphasizes low-inductance grounding (multiple vias to inner ground plane) and placement adjacent to the protected connector-not thermal mass addition. This simplifies layout for the TDS2211P in space-constrained designs.
How does the TDS2211P compare to standard TVS diodes in temperature-dependent clamping performance?
The TDS2211P maintains clamping voltage within 27.5–28 V from –40°C to +125°C, whereas standard TVS diodes exhibit significant positive temperature coefficient-clamping may rise >35 V at 125°C under identical 40A surge conditions. This stability arises from the TDS2211P's active trigger+FET architecture, which decouples clamping from junction temperature. As a result, TDS2211P enables tighter, more reliable system-level overvoltage margins in thermally aggressive environments without derating.
Is the TDS2211P pin-compatible with other Semtech TDS family members like TDS2411P?
No-the TDS2211P is not pin-compatible with TDS2411P or other TDS variants. While all share the same DFN-6 (1.6×1.6 mm) footprint and 3-GND / 3-IN pin grouping, their working voltages differ (TDS2411P = 24V VRWM), and absolute maximum ratings (e.g., VBR, IPP) are not interchangeable. Substituting TDS2211P for TDS2411P risks premature triggering or insufficient clamping headroom; each TDS2211P application must be validated for its specific 22V bus requirement.
