Product details
Overview
TDS2201P.F from Semtech is a transient diverting suppressor designed for single-line EOS/ESD protection on 22V-rated power or data lines, featuring ±8kV contact / ±30kV air ESD immunity per IEC 61000-4-2, 16A peak pulse current (8/20μs), and 28V max clamping voltage at full current-ideal for USB Type-C VBUS and IoT device power rail protection.
For engineers reviewing the TDS2201P.F datasheet, pinout, applications, or equivalent options, key selection criteria include its 22V working voltage, DFN 1.0×0.6mm 2-lead package, sub-6mΩ dynamic resistance, 58pF junction capacitance at 22V, and FET-based clamping architecture enabling flat voltage response across surge current range.
Technical Context
The TDS2201P.F uses a surge-rated MOSFET as its primary protection element, activated by an integrated precision trigger circuit that switches the FET on when transient voltage exceeds ~26.5V breakdown. Unlike conventional TVS diodes, its clamping voltage remains nearly constant (26.4–28V) from 1A to 16A due to decreasing RDS(on) under surge conditions.
It operates over –40°C to +85°C, maintains low leakage (<500nA at 25°C, <750nA at 85°C), and delivers 450W peak pulse power (8/20μs). Its 58pF capacitance at 22V and 1MHz makes it suitable for high-speed lines where signal integrity must be preserved alongside robust surge immunity.
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 conduction. |
| Clamping Voltage | 28V max at 16A (8/20μs) - ensures downstream ICs see ≤28V during worst-case surge, critical for 3.3V/5V/12V logic and PMIC inputs. |
| Peak Pulse Current | 16A (8/20μs) - supports IEC 61000-4-5 Level 3 (±1kV, 42Ω source) surge immunity on industrial and consumer power rails. |
| ESD Rating | ±8kV contact / ±30kV air (IEC 61000-4-2) - exceeds standard USB and mobile interface ESD requirements with margin. |
| Junction Capacitance | 58pF at 22V, 1MHz - low enough to avoid signal degradation on USB 2.0 and 10/100Mbps Ethernet lines. |
| Dynamic Resistance | 6mΩ - enables near-constant clamping by minimizing IR drop across protection element during high-current transients. |
| Package | DFN 1.0×0.6×0.25mm, 2-lead - saves >70% board area vs. SMAJ/SMBJ packages while maintaining thermal performance via copper pad exposure. |
Pinout & Package
Package: DFN 1.0×0.6×0.25mm, 2-lead, exposed thermal pad (non-electrical), RoHS-compliant Pb-free finish, marking "T2" with bar indicating Pin 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Input (Protected Line) | Connects to VBUS or signal line requiring protection; withstands 22V DC and absorbs surge energy into ground path. |
| Pin 2 | Ground | Low-inductance return path to system ground plane; must be routed with minimal trace length and connected to large copper pour for effective energy dissipation. |
Key Features

IC Role / Device Role / Timing Role: First-line defense before buck converter or battery charger IC, absorbing fast-rising transients before they reach regulation circuitry. Use Value: Enables compact form factor by replacing larger SMAJ33A with same 22V working voltage but 75% smaller footprint and superior clamping consistency. | Use Scenario: Protecting 19V DC-in jacks in ultrabooks and 2-in-1 tablets against accidental AC adapter misconnection and lightning-induced surges. IC Role / Device Role / Timing Role: High-energy shunt suppressor mounted at board edge near DC jack, sinking surge current directly to ground plane. Use Value: Maintains system uptime by preventing brownouts or resets triggered by transient-induced voltage sag on 19V rail during 1.2/50μs surges. |
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; 33.2V clamping at 13.9A (8/20μs); 100pF capacitance; SMA package (4.5×2.7mm). | Higher clamping voltage reduces protection margin for 3.3V/5V logic; larger size limits routing near connectors. | Select when cost sensitivity outweighs clamping performance and board space constraints are relaxed. |
| SP1003-02UTG | Bi-directional TVS array; 24V working voltage; 33V clamping at 12A; 15pF typical; SOD-323 package (1.7×1.25mm). | Lower capacitance suits high-speed data lines but lacks 16A surge rating; not rated for 1kV IEC 61000-4-5. | Select for USB 2.0 data line protection where low capacitance is prioritized over high-energy power rail immunity. |
Compared with SMAJ22A and SP1003-02UTG, the TDS2201P.F provides significantly lower clamping voltage (28V vs. ≥33V), flatter response across current range, and 70% smaller footprint-making it optimal for space-constrained 22V power rail protection where consistent surge suppression is critical.

FAQ
What is the maximum clamping voltage of the TDS2201P.F at 16A surge current?
The TDS2201P.F has a maximum clamping voltage of 28V at 16A peak pulse current (8/20μs waveform), as specified in its Electrical Characteristics table. This value is guaranteed by design and reflects the device's FET-based architecture, which maintains near-constant clamping across its full current range-unlike traditional TVS diodes whose clamping rises linearly with current. The TDS2201P.F achieves this via ultra-low dynamic resistance (6mΩ) and precision trigger control.
Can the TDS2201P.F be used on bidirectional signal lines like USB D+/D–?
No, the TDS2201P.F is a unidirectional device intended for single-line protection between a positive rail (e.g., VBUS) and ground. Its electrical characteristics-including reverse stand-off voltage (22V), breakdown voltage (~26.5V), and forward voltage (0.5V)-are defined for line-to-ground operation only. For bidirectional data lines such as USB D+/D–, a dedicated bi-directional TVS like SP1003-02UTG or similar is required. The TDS2201P.F must not be applied across differential pairs or reverse-biased signal paths.
What is the thermal pad connection requirement for the TDS2201P.F DFN package?
Although the TDS2201P.F DFN package includes an exposed thermal pad, Semtech documentation confirms it is non-electrical and intended solely for mechanical anchoring and thermal conduction. The pad must be soldered to a solid copper ground plane using standard reflow profiles (per JEDEC J-STD-020), but no electrical connection is required or recommended. Improper grounding of this pad does not affect electrical performance, but omitting solder paste may compromise mechanical reliability during thermal cycling.
How does the TDS2201P.F compare to standard TVS diodes in temperature stability?
The TDS2201P.F exhibits superior temperature stability compared to standard TVS diodes: its clamping voltage varies by less than 1.5V from –40°C to +85°C, whereas conventional TVS devices show significant increase in both clamping voltage and leakage current with rising temperature. This stability stems from its FET-based architecture, where the trigger circuit's breakdown voltage dominates clamping behavior rather than junction-dependent parameters. As a result, the TDS2201P.F maintains consistent protection margins across automotive and industrial ambient conditions.
Is the TDS2201P.F compliant with IPC/JEDEC standards for moisture sensitivity?
Yes, the TDS2201P.F is rated at Moisture Sensitivity Level (MSL) 1 per IPC/JEDEC J-STD-033, meaning it has unlimited floor life and does not require dry pack or baking prior to assembly. This is confirmed by Semtech's packaging specification and reflow profile guidance (JEDEC J-STD-020 compliant). The device's DFN 1.0×0.6mm package uses UL 94V-0 molding compound and Pb-free, halogen-free materials, ensuring compatibility with standard SMT processes without moisture-related popcorning risks.
