Product details
Overview
TS13401ULTRT from Semtech is a Transient Diverting Suppressor (TDS) designed for high-energy EOS protection of 22V-rated power or I/O lines, featuring ±30kV IEC 61000-4-2 ESD immunity, 40A peak pulse current (8/20μs), and stable 27.5–28V clamping across temperature and current range. It protects USB PD, USB Type-C VBus, and load switch inputs in industrial and portable electronics.
For engineers reviewing the TS13401ULTRT datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, DFN-6 package layout guidance, real-world clamping behavior vs. conventional TVS, and validated alternatives for 22V bus protection design.
Technical Context
The TS13401ULTRT 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. Unlike standard TVS diodes, its clamping voltage remains nearly constant-27.5–28V at 24A and 40A-due to decreasing RDS(on) under surge conditions.
It operates from −40°C to +125°C with <20mΩ dynamic resistance, 175pF junction capacitance at 22V/1MHz, and <600nA reverse leakage. Its functional architecture enables stable protection for high-voltage USB PD buses and load switch inputs where thermal drift and current-dependent clamping are critical failure modes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage (VRWM) | 22V - defines maximum continuous DC operating voltage on protected line without leakage or conduction. |
| Clamping Voltage (VC) | 27.5–28V at 40A (8/20μs + 1.2/50μs combo wave, RS=2Ω) - ensures downstream 24V-rated ICs (e.g., USB PD controllers) remain below damage threshold during surge. |
| Peak Pulse Current (IPP) | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 industrial surge immunity requirements for 22V systems. |
| ESD Withstand | ±30kV contact & air per IEC 61000-4-2 - exceeds automotive and industrial ESD robustness requirements for external connectors. |
| Junction Capacitance (CJ) | 175pF at 22V, 1MHz - low enough for VBus protection without signal integrity impact; not suitable for high-speed data lines. |
| Dynamic Resistance (RDYN) | 20mΩ - enables flat clamping curve; reduces voltage overshoot during fast-rising transients compared to TVS diodes. |
| Package | DFN 1.6mm × 1.6mm × 0.55mm, 6-lead - ultra-compact footprint saves board space versus SOD-123 or SMA TVS solutions. |
Pinout & Package
TS13401ULTRT is housed in a Pb-free, RoHS-compliant DFN-6 package (1.6mm × 1.6mm × 0.55mm) with exposed thermal pad not required-energy is dissipated in the silicon FET, not junction heating. All six terminals must be connected: pins 1–3 as common ground return, pins 4–6 as parallel-connected input to protected line.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground reference for trigger circuit and shunt FET source; all three must be low-inductance connected to PCB ground plane via multiple vias. |
| Pins 4, 5, 6 | IN | Parallel-connected input node tied directly to protected bus (e.g., USB PD VBus); all three required to achieve full 40A rating and minimize trace inductance. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies ≤0.5V from 24A to 40A surge-enables predictable protection margin without overdesigning for worst-case current. |
| Temperature-stable clamping | Clamps at ~27.5V from −40°C to +125°C-eliminates derating needed for TVS diodes whose VC rises >10% over same range. |
| Low dynamic resistance | 20mΩ RDYN minimizes IR drop during surge-critical for maintaining low VC at high dI/dt events like lightning-induced surges. |
| Integrated FET-based protection | Replaces discrete TVS + MOSFET crowbar circuits-reduces BOM count, layout complexity, and parasitic inductance in high-reliability power rail protection. |
| DFN-6 compact packaging | 1.6mm × 1.6mm footprint occupies ~30% less area than comparable SOT-23-6 TVS arrays-ideal for space-constrained USB-C and IoT edge nodes. |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
|
Use Scenario: Protecting 20–22V USB PD VBus lines against ESD, lightning surges, and connector hot-plug transients in notebooks, docking stations, and chargers. IC Role / Device Role / Timing Role: Primary EOS shunt protector placed at connector entry point; clamps transients before they reach PD controller or buck converter input. Use Value: Maintains 27.5V clamping at 40A and 125°C-prevents overvoltage damage to 24V-rated PD controllers where conventional TVS would exceed 35V at same conditions. |
Use Scenario: Safeguarding enable and input pins of industrial-grade load switches (e.g., HS2950P) in remote meters, robotics, and factory automation equipment. IC Role / Device Role / Timing Role: Front-end transient suppressor that limits voltage seen by internal FET gate oxide and drain-source junction during surge events. Use Value: Keeps clamping voltage below 28V across full temperature range-avoids gate oxide rupture or avalanche failure in load switches rated for ≤30V absolute max. |
| IoT Edge Node Power Rail Protection | USB-C Docking Station VBus Protection |
|
Use Scenario: Securing 22V auxiliary power rails in battery-powered IoT gateways and smart sensors exposed to field ESD and induced surges. IC Role / Device Role / Timing Role: Single-device solution for EOS protection of always-on power inputs, replacing multi-component TVS+RC networks. Use Value: Delivers ±30kV ESD immunity and 40A surge handling in 1.6mm² footprint-enables ruggedized designs without sacrificing PCB area or thermal management complexity. |
Use Scenario: Protecting upstream VBus lines in multi-port USB-C docking stations handling up to 100W PD negotiation and simultaneous peripheral attachment. IC Role / Device Role / Timing Role: High-current transient diverter placed per-port at physical connector, coordinated with low-capacitance TVS on CC/SBU lines. Use Value: Enables reliable 40A surge sharing across parallel pins-ensures no single trace or via becomes bottleneck during multi-port surge testing per IEC 61000-4-5. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDS2211P | Identical electrical specs, pinout, and package; TS13401ULTRT is Semtech's alternate marking for TDS2211P per official ordering documentation. | Same use cases: USB PD VBus, load switch input, industrial 22V rails. | Select TS13401ULTRT for tape-and-reel procurement compatibility with Semtech's standard distribution channels. |
| SMAJ22A | Standard unidirectional TVS diode; 22V VRWM, 35.5V VC @ 24A, 500mΩ RDYN, 1000pF CJ; no temperature stability or flat-clamp behavior. | Acceptable only for lower-energy, ambient-temperature-limited applications where 35.5V clamping is tolerable. | Choose SMAJ22A only if cost is primary constraint and system-level testing confirms 35.5V clamping does not violate downstream IC abs-max ratings. |
Compared with TDS2211P (identical device) and SMAJ22A (conventional TVS), TS13401ULTRT delivers superior surge margin through flat 27.5V clamping across current and temperature-enabling smaller, more reliable protection for 22V USB PD and industrial power rails without overvoltage risk.

FAQ
What is the exact package type and dimensions of TS13401ULTRT?
TS13401ULTRT uses a DFN-6 package measuring 1.6mm × 1.6mm × 0.55mm with 0.5mm pitch. Pins 1–3 are GND; pins 4–6 are IN. The package is Pb-free, halogen-free, and RoHS/WEEE compliant with UL 94V-0 molding compound. No thermal pad is required-energy dissipates in the silicon FET.
How does TS13401ULTRT differ from standard TVS diodes in clamping behavior?
Unlike TVS diodes whose clamping voltage rises linearly with peak current (VC = VBR + IPP × RDYN), TS13401ULTRT maintains ~27.5V clamping from 24A to 40A due to its FET-based architecture and decreasing RDS(on). This eliminates need for overrating IPP to meet VC targets and ensures consistent protection across temperature.
Can TS13401ULTRT protect high-speed data lines like USB SS or PCIe?
No-TS13401ULTRT has 175pF junction capacitance, making it unsuitable for high-speed differential data lines. It is intended exclusively for power or low-frequency I/O lines (e.g., USB PD VBus, CC, SBU, or load switch enable). For SuperSpeed lanes, use sub-0.3pF devices like RClamp3371ZC.
What is the maximum operating temperature range for TS13401ULTRT?
TS13401ULTRT is rated for continuous operation from −40°C to +125°C ambient. Its clamping voltage remains stable across this full range-measured at ~27.5V at 40A from −40°C to +125°C-unlike TVS diodes whose VC typically increases >15% over the same interval.
Is TS13401ULTRT pin-compatible with other Semtech TDS devices?
TS13401ULTRT shares the same DFN-6 pinout and footprint as TDS2211P and is functionally identical. However, it is not pin-compatible with other TDS variants (e.g., TDS1211P or TDS3611P) which differ in working voltage, clamping level, and internal trigger thresholds-each requires separate layout and validation.
