Product details
Overview
TDS2211P from Semtech is a transient diverting suppressor designed for high-energy EOS protection on 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 - deployed 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, this page delivers verified electrical parameters, DFN-6 package layout guidance, functional role in EOS shunt activation, and direct alternatives for 22V bus protection with constant-clamp performance.
Technical Context
The TDS2211P uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit that senses overvoltage events above ~25V breakdown. Unlike conventional TVS diodes, its clamping voltage remains nearly flat (27.5–28V) from 24A to 40A due to decreasing RDS(on) under surge conditions.
It operates across –40°C to +125°C with <600nA reverse leakage at 22V, 175pF junction capacitance at 22V/1MHz, and 20mΩ dynamic resistance measured between 1A and 40A (8/20μs), enabling robust protection without thermal derating penalties typical of junction-based TVS devices.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC bus voltage before leakage or triggering begins. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs + 1.2/50μs combo waveform) - ensures protected ICs (e.g., USB PD controllers) remain below damage thresholds. |
| 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 automotive and industrial ESD stress levels without degradation. |
| Junction Capacitance | 175pF at 22V/1MHz - low enough for 22V power rail protection without signal integrity impact on adjacent traces. |
| Dynamic Resistance | 20mΩ - enables near-constant clamping by minimizing IR drop increase under rising surge current. |
| Package | DFN 1.6mm × 1.6mm × 0.55mm, 6-lead - supports ultra-compact placement near connectors with minimal PCB area. |
Pinout & Package
Package: DFN 1.6mm × 1.6mm × 0.55mm, 6-lead, Pb-free, RoHS-compliant, UL 94V-0 molding compound. Thermal pad not required; energy dissipated in silicon FET structure.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground return path for surge current; all three must be connected to maximize current sharing and minimize inductance. |
| 4, 5, 6 | IN | Protected line input (e.g., VBUS, load switch input); parallel connection ensures uniform current distribution and full 40A rating. |
Key Features
| Feature | Design Value |
|---|---|
| FET-based shunt architecture | Enables flat clamping voltage vs. current and temperature - eliminates thermal runaway risk seen in PN-junction TVS devices. |
| Constant clamping across 24–40A | 27.5–28V window ensures predictable protection margin regardless of surge magnitude within rated range. |
| Low dynamic resistance (20mΩ) | Minimizes voltage overshoot during fast-rising transients and sustains low clamping under multi-pulse stress. |
| High EFT immunity (±4kV, 5/50ns) | Withstands repetitive burst noise common in industrial motor drives and switching power supplies without parameter shift. |
| DFN-6 footprint compatibility | Enables drop-in replacement of legacy TVS arrays in space-constrained USB-C and IoT designs without layout revision. |

Use Value: Eliminates need for oversized TVS or redundant protection stages due to stable clamping and no thermal derating. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ22A | PN-junction TVS diode; clamping rises from ~35V @24A to ~42V @40A; higher dynamic resistance (~0.5Ω). | Limited to lower-temperature environments (<85°C ambient); requires larger derating margin for same surge level. | Choose SMAJ22A only when cost sensitivity outweighs clamping stability and temperature resilience. |
| TPD2E007DRYR | Low-capacitance (1.5pF) dual-channel TVS; 22V standoff but rated only for 4A (8/20μs); no industrial surge rating. | Targeted for high-speed data lines (e.g., USB 2.0 D+/D−), not power rail protection. | Use TPD2E007DRYR for signal-line ESD only; not suitable as TDS2211P replacement for 40A bus protection. |
Compared with SMAJ22A and TPD2E007DRYR, the TDS2211P uniquely delivers flat 27.5–28V clamping at 40A across –40°C to +125°C, making it the only option among the three qualified for industrial-grade 22V power rail surge suppression without thermal or current derating.

FAQ
What is the clamping voltage behavior of the TDS2211P under varying surge currents?
The TDS2211P maintains a tightly bounded clamping voltage of 27.5–28V across its full rated peak pulse current range (24A to 40A, 8/20μs + 1.2/50μs combo waveform). This flat response results from the FET's decreasing RDS(on) under surge, unlike conventional TVS diodes whose clamping rises linearly with current. The TDS2211P datasheet confirms this behavior is guaranteed across –40°C to +125°C.
Can the TDS2211P replace standard TVS diodes in existing 22V protection circuits without layout changes?
Yes - the TDS2211P uses a DFN-6 package (1.6mm × 1.6mm) compatible with standard TVS footprints for single-line protection. However, all six pins must be correctly assigned: pins 1–3 to GND and pins 4–6 to IN. Its low 175pF capacitance and absence of thermal pad requirements simplify integration, but routing must ensure low-inductance GND vias per Semtech's layout guidelines for full 40A performance.
How does the TDS2211P perform under repeated EFT bursts compared to standard TVS devices?
The TDS2211P withstands ±4kV EFT (IEC 61000-4-4, 5/50ns, 5kHz & 100kHz) without parameter shift or degradation, thanks to its FET-based architecture that avoids junction heating and cumulative damage mechanisms inherent in PN-junction TVS diodes. Its solid-state design ensures consistent clamping and leakage (<600nA at 22V) even after thousands of EFT pulses - validated in Semtech's reliability testing.
Is the TDS2211P suitable for protecting USB-C CC and SBU lines?
No - the TDS2211P is designed for 22V power rail or high-current I/O protection (e.g., VBUS, load switch inputs), not low-voltage, high-speed signal lines. For CC/SBU protection, Semtech recommends uClamp2411ZA (24V standoff, low capacitance), which avoids mis-triggering and preserves signal integrity. Using TDS2211P on CC/SBU would introduce excessive capacitance and violate USB-C specification timing margins.
What is the maximum operating temperature range for the TDS2211P, and how does clamping vary across it?
The TDS2211P operates from –40°C to +125°C, with clamping voltage remaining stable at 27.5–28V across the full range - confirmed by datasheet graphs (Figure 3, "Clamping Voltage vs. Temperature"). This contrasts sharply with standard TVS diodes, whose clamping typically increases by 0.1–0.2V/°C. The TDS2211P's FET-based architecture eliminates temperature-dependent junction effects, ensuring reliable protection in automotive under-hood or industrial control cabinet environments.
