Product details
Overview
TDS2211P from Semtech is a transient diverting suppressor designed to protect 22V-rated I/O or power lines against EOS, ESD, and surge events. It delivers ±30kV IEC 61000-4-2 contact/air ESD immunity, 40A (8/20μs) peak pulse current handling, 27.5–28V clamping voltage at 24–40A, and 20mΩ dynamic resistance - enabling robust protection in USB Type-C PD and industrial load switch inputs.
For engineers reviewing the TDS2211P datasheet, pinout, applications, or equivalent options, key selection criteria include its constant-clamp behavior across temperature and current, DFN 1.6×1.6mm 6-lead footprint, low 175pF junction capacitance, and FET-based shunt architecture that avoids voltage rise with increasing surge current.
Technical Context
The TDS2211P uses a precision-triggered surge-rated FET as its primary protection element, activated by a dedicated trigger circuit when transient voltage exceeds breakdown. Unlike conventional TVS diodes, its clamping voltage remains stable - ~27.5–28V - from 24A to 40A (1.2/50μs + 8/20μs combo waveform) due to decreasing RDS(on) under surge conditions.
It operates over –40°C to +125°C with <600nA reverse leakage at 22V, 175pF capacitance at 22V/1MHz, and thermal stability verified up to +150°C junction temperature. Its 6-pin DFN package assigns pins 1–3 exclusively to GND and pins 4–6 exclusively to IN, requiring all three terminals per side for full 40A rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC bus voltage it safely guards without leakage or degradation |
| Clamping Voltage | 27.5–28V at 40A (8/20μs) - ensures protected ICs (e.g., USB PD controllers) remain below damage threshold during worst-case surge |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 industrial surge immunity requirements |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds smartphone/tablet ESD test requirements by 3× |
| Dynamic Resistance | 20mΩ - enables near-constant clamping by minimizing IR drop increase under rising current |
| Junction Capacitance | 175pF at 22V/1MHz - low enough for USB Type-C VBUS line without signal integrity impact |
| Package | DFN 1.6×1.6×0.55mm, 6-lead - saves >50% board area vs. SO-8 TVS alternatives while supporting high-current routing |
Pinout & Package
Package: DFN 1.6 mm × 1.6 mm × 0.55 mm, 6-lead, Pb-free, RoHS-compliant, UL 94V-0 molding compound. Exposed thermal pad not required - energy dissipation occurs in silicon FET, not junction heating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground return path - all three must be connected with low-inductance vias to maximize 40A surge current capability |
| Pins 4, 5, 6 | IN | Protected line input - all three tied together to VBUS or power rail; single-point connection minimizes trace inductance before suppression |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies ≤0.5V across full 24–40A surge range - eliminates design margin inflation needed with TVS diodes |
| FET-based shunt protection | Surge energy diverted through low-RDS(on) channel instead of PN-junction - enables stable performance up to +125°C ambient |
| Low dynamic resistance | 20mΩ measured between 1A–40A (8/20μs) - directly enables flat clamping curve and minimal voltage overshoot |
| High-energy surge rating | 1120W peak pulse power (8/20μs) - supports repeated lightning-surge events in industrial equipment without derating |
| Minimal layout dependency | No thermal pad required; performance validated with standard PCB copper - reduces layout complexity vs. power TVS solutions |
Applications
| USB Type-C Power Delivery Protection | Industrial Load Switch Input Protection |
|---|---|
|
Use Scenario: Protecting 20V–22V VBUS lines in USB-C ports with Power Delivery negotiation, exposed to ESD and system-level surges. IC Role / Device Role / Timing Role: Primary EOS shunt suppressor placed at connector entry point, clamping transients before reaching PD controller and load switch. Use Value: Maintains 27.5–28V clamp across –40°C to +125°C - prevents false overvoltage shutdown and guarantees PD controller survival where TVS diodes exceed safe limits at elevated temperature. |
Use Scenario: Safeguarding input of high-side load switches (e.g., HS2950P) in remote meters, robotics, and IoT gateways subjected to lightning-induced surges. IC Role / Device Role / Timing Role: Front-end transient diverter that limits voltage stress on the load switch's internal MOSFET drain-source junction during 1kV/42Ω surges. Use Value: Enables use of cost-optimized load switches without integrated surge protection - eliminates need for external series impedance or oversized FETs to withstand transient overvoltage. |
| IoT Edge Device Power Bus Protection | Storage Device 22V Rail Protection |
|
Use Scenario: Securing 22V auxiliary rails in battery-backed smart sensors and gateway hubs operating in uncontrolled environments (e.g., outdoor kiosks, factory floors). IC Role / Device Role / Timing Role: Single-component solution for combined ESD, EFT (±4kV), and surge (40A) protection on always-on power inputs. Use Value: Delivers certified IEC 61000-4-2/4-4/4-5 compliance in <2.56 mm² footprint - replaces multi-device TVS+filter networks while reducing BOM count and test complexity. |
Use Scenario: Protecting 22V supply rails in NVMe SSD enclosures and enterprise storage backplanes exposed to hot-plug transients and chassis ESD. IC Role / Device Role / Timing Role: Fast-acting shunt device placed upstream of PMIC regulators and flash memory power domains. Use Value: 175pF capacitance avoids resonance with typical 10–100μF bulk capacitors - preserves power rail stability during surge events without requiring additional damping components. |
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; 35.1V min clamping at 12.5A (8/20μs); 600W peak power; 3.5pF typical capacitance | Larger 403 mW package; clamping rises to ~42V at 40A and increases with temperature; no constant-clamp behavior | Choose SMAJ22A only if ultra-low capacitance (<1pF) is mandatory and surge current ≤12.5A suffices |
| TPD2E007DRYR | 2-channel 7V TVS array; 15kV ESD; 3A peak pulse; 0.9pF per line; SOT-563 package | Rated for 7V working voltage - unsuitable for 22V VBUS; intended for data-line (CC/SBU) protection, not power rail | Use TPD2E007DRYR only for low-voltage signal-line protection alongside TDS2211P - never as direct replacement |
Compared with SMAJ22A and TPD2E007DRYR, the TDS2211P uniquely combines 22V working voltage, 40A surge rating, and temperature-stable 28V clamping in a 1.6×1.6mm DFN - making it the only option capable of protecting USB PD VBUS and industrial 22V inputs without derating or thermal compromise.

FAQ
What is the maximum continuous operating voltage for the TDS2211P?
The TDS2211P has a reverse stand-off voltage (VRWM) of 22V, meaning it is rated for continuous DC operation up to 22V on the protected line. Exceeding this voltage risks increased leakage current and potential degradation. The device's 25–27.9V breakdown voltage (VBR) provides headroom above VRWM, but sustained operation above 22V is not recommended. Always verify system rail tolerances align with the TDS2211P's 22V VRWM specification.
Does the TDS2211P require a thermal pad on the PCB?
No, the TDS2211P does not require an exposed thermal pad. Its FET-based architecture dissipates surge energy in the channel rather than the junction, eliminating the need for enhanced thermal conduction. The datasheet explicitly states "no thermal pad is needed," and performance is validated using standard copper pours on inner layers. This simplifies layout and reduces manufacturing complexity compared to thermally demanding TVS solutions.
Can the TDS2211P be used on USB SuperSpeed differential pairs?
No, the TDS2211P is not suitable for USB SuperSpeed (TX/RX) differential signaling lines. Its 175pF junction capacitance would severely distort high-speed signals. For those lines, Semtech recommends low-capacitance devices like RClamp3371ZC (<0.25pF). The TDS2211P is designed exclusively for single-ended, high-energy paths such as VBUS, CC, or load switch inputs - not data lanes.
How does the TDS2211P's clamping performance compare to standard TVS diodes at high temperature?
Unlike standard TVS diodes whose clamping voltage rises significantly with temperature, the TDS2211P maintains stable clamping - 27.5–28V across –40°C to +125°C at 40A. This is due to its FET-based shunt mechanism, where RDS(on) decreases with temperature, counteracting voltage rise. In contrast, a typical 22V TVS may clamp at ~38V at 125°C and 24A, risking damage to downstream ICs. The TDS2211P thus enables more reliable protection in thermally demanding environments.
Is the TDS2211P pin-compatible with other Semtech TDS devices like TDS2411P?
No, the TDS2211P is not pin-compatible with TDS2411P or other TDS variants. While all share the same 6-pin DFN 1.6×1.6mm package outline, their pin functions differ: TDS2211P uses pins 1–3 as GND and 4–6 as IN, whereas TDS2411P (24V version) has different internal routing and trigger thresholds. Substituting without verifying pin mapping and electrical compatibility risks misprotection or failure. Always consult the respective datasheets before interchange.
