Product details
Overview
TDS2211P from Semtech is a transient diverting suppressor designed to protect 22V-rated I/O or power lines against high-energy EOS events including ESD (±30kV contact/air), EFT (±4kV), and surge (40A, 8/20μs). It uses a surge-rated FET with precision trigger circuitry to deliver stable clamping voltage across temperature and current range, enabling robust protection in USB Type-C PD and industrial load switch inputs.
For engineers reviewing the TDS2211P datasheet, pinout, applications, or equivalent options, this device offers constant clamping (~27.5–28V at 24–40A), ultra-low dynamic resistance (20mΩ), low leakage (<600nA at 22V), and DFN 1.6×1.6mm package - critical for space-constrained, high-reliability bus protection designs.
Technical Context
The TDS2211P implements a voltage-triggered shunt architecture: a precision breakdown reference activates a drive circuit that turns on a low-RDS(on) FET during overvoltage transients. Unlike conventional TVS diodes, its clamping voltage remains nearly flat (27.5–28V) from 24A to 40A and across –40°C to +125°C due to decreasing FET resistance under surge.
This architecture enables superior energy handling (1120W peak pulse power) while maintaining low junction capacitance (175pF at 22V, 1MHz) and minimal temperature drift - key for protecting sensitive 22V-bus interfaces like USB PD controllers and load switch inputs without signal integrity degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage (VRWM) | 22 V - defines maximum continuous DC operating voltage of protected line without leakage or conduction. |
| Clamping Voltage (VC) | 27.5–28 V at 40A (8/20μs) - ensures downstream ICs (e.g., USB PD controllers) remain below damage threshold during worst-case surge. |
| Peak Pulse Current (IPP) | 40 A (8/20μs) - meets IEC 61000-4-5 Level 4 industrial surge immunity requirements for 22V systems. |
| Dynamic Resistance (RDYN) | 20 mΩ - enables near-constant clamping by minimizing I×R voltage rise across surge current range. |
| Junction Capacitance (CJ) | 175 pF at 22V, 1MHz - low enough to avoid signal distortion on moderate-speed buses (e.g., USB 2.0, CC/SBU lines). |
| ESD Withstand | ±30 kV (IEC 61000-4-2 contact/air) - exceeds Level 4 ESD immunity for end-equipment certification. |
| Operating Temperature | –40°C to +125°C - supports deployment in automotive-grade and industrial environments without derating. |
Pinout & Package
Package: DFN 1.6 mm × 1.6 mm × 0.55 mm, 6-lead, RoHS-compliant, UL 94V-0 molding compound. Exposed thermal pad not required; all GND pins must be connected for full surge rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground return path for surge current; all three must be connected to minimize inductance and maximize 40A capability. |
| Pins 4, 5, 6 | IN | Protected line input (e.g., VBus, load switch input); parallel connection ensures uniform current sharing and thermal distribution. |
Key Features
| Feature | Design Value |
|---|---|
| Constant clamping voltage | 27.5–28 V across 24–40A and –40°C to +125°C - eliminates need for derating or safety margin inflation in thermal design. |
| Surge-rated FET protection element | RDS(on) < 0.1 Ω under surge - delivers lower clamping than TVS diodes and avoids thermal runaway at high ambient temperatures. |
| Low dynamic resistance | 20 mΩ - reduces voltage overshoot during fast-rising transients (e.g., ESD), improving system-level immunity. |
| High EFT immunity | ±4 kV per IEC 61000-4-4 (5/50 ns, 5 kHz & 100 kHz) - protects against repetitive burst noise in industrial control and IoT edge nodes. |
| Space-efficient packaging | 1.6 mm × 1.6 mm footprint - saves >50% board area vs. traditional SMA/SMB TVS solutions rated for same 40A surge. |
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 hot-plug ESD. IC Role / Device Role / Timing Role: Transient diverting suppressor placed directly at connector, clamping overvoltage before it reaches PD controller or e-fuse. Use Value: Maintains 27.5–28V clamping at 40A and 125°C - prevents false triggering or latch-up in PD controllers that tolerate ≤30V absolute max. |
Use Scenario: Safeguarding input terminals of high-side load switches (e.g., HS2950P) in remote meters and robotics against 1kV/42Ω surges. IC Role / Device Role / Timing Role: Primary front-end protector that limits voltage seen by internal FET gate oxide and drain-source junction. Use Value: Clamps below 28V regardless of ambient temperature - avoids permanent damage to load switch RDS(on) or OVP circuitry during field-deployed surge events. |
| IoT Edge Node Power Rail Protection | Storage Device 22V Backup Supply Protection |
Use Scenario: Securing 22V auxiliary rails in battery-backed smart sensors exposed to ESD during handling and EFT in factory automation environments. IC Role / Device Role / Timing Role: Single-device solution replacing multi-stage TVS+RC networks for compact, certified immunity. Use Value: ±30kV ESD and ±4kV EFT ratings meet IEC 61000-4-2/4-4 Level 4 - reduces qualification test failures and field returns. |
Use Scenario: Protecting 22V supercapacitor or LiFePO4 backup supplies in enterprise SSDs and NAS enclosures from power-line transients. IC Role / Device Role / Timing Role: Low-capacitance (175pF), low-leakage (≤600nA) protector preserving hold-up time and standby current budget. Use Value: Stable 22V working voltage and 28V clamping ensure backup rail stays within safe operating area during AC line disturbances. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient protection 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); 600pF capacitance. | Larger footprint (SMA), higher clamping voltage limits use with 30V-tolerant ICs; unsuitable for high-temp industrial operation without derating. | Choose SMAJ22A only if cost is primary constraint and clamping margin >12V is acceptable; not recommended for USB PD or compact layouts. |
| SP1003-220 | Bi-directional TVS array; 22V VRWM; clamps ~36V at 40A; 25pF typical capacitance; SOT-23-3 package. | Lower capacitance benefits high-speed data lines but lacks TDS2211P's flat clamping and 40A single-line rating; limited to ≤20A per line in multi-line configs. | Use SP1003-220 for space-constrained, low-capacitance needs where 36V clamping is tolerable; not suitable for 22V bus protection requiring sub-30V clamping. |
Compared with SMAJ22A and SP1003-220, TDS2211P uniquely delivers 27.5–28V clamping at full 40A and 125°C in a 1.6×1.6mm DFN - enabling smaller, more reliable protection for 22V systems where voltage margin is tight and thermal environment is demanding.

FAQ
What is the maximum continuous operating voltage for TDS2211P?
The TDS2211P has a reverse stand-off voltage (VRWM) of 22 V, meaning it can continuously block up to 22 V DC without significant leakage or conduction. This makes TDS2211P suitable for protecting 22V nominal power rails such as USB PD VBus and industrial 24V auxiliary supplies.
How does TDS2211P achieve constant clamping voltage across surge current?
TDS2211P achieves constant clamping by using a surge-rated FET as the main protection element. When triggered, the FET's RDS(on) decreases under higher current, counteracting the I×R voltage rise. As a result, TDS2211P maintains 27.5–28 V clamping from 24A to 40A - unlike TVS diodes whose clamping rises linearly with current.
Is TDS2211P compatible with automated PCB assembly processes?
Yes, TDS2211P is supplied in tape-and-reel format (3,000 units per 7-inch reel) and features a standard DFN 1.6×1.6mm package with lead-free, halogen-free terminations compliant with IPC/JEDEC J-STD-020 moisture sensitivity level 1. Its land pattern and thermal profile are fully compatible with standard reflow soldering processes.
Can TDS2211P replace a standard TVS diode in an existing design?
TDS2211P can replace a standard TVS diode only if the layout accommodates its 6-pin DFN package and all GND (pins 1–3) and IN (pins 4–6) connections are properly implemented. Due to its lower clamping voltage and different surge response, electrical validation is required - especially for timing-critical or high-frequency signal paths.
What is the junction capacitance of TDS2211P and how does it affect signal integrity?
TDS2211P exhibits 175 pF junction capacitance at 22 V and 1 MHz. This value is appropriate for protecting moderate-speed buses (e.g., USB 2.0, CC/SBU, power rails) but not recommended for SuperSpeed USB 3.x or PCIe lanes where sub-1pF capacitance is required. For those, low-capacitance TVS arrays like RClamp3371ZC should be used alongside TDS2211P.
