Product details
Overview
TDS4001P.C from Semtech is a transient diverting suppressor designed for high-energy EOS protection of 40V-rated power or I/O lines, featuring ±30kV IEC 61000-4-2 ESD immunity, 40A peak pulse current (8/20μs), and stable 35V clamping voltage across temperature and current range-used in USB PD input protection, industrial load switch front-end safeguarding, and 24–40V DC bus surge suppression.
For engineers reviewing the TDS4001P.C datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, DFN-6 package layout guidance, real-world clamping behavior vs. conventional TVS, and validated alternatives for 40V EOS protection in USB Type-C, IoT, and industrial power systems.
Technical Context
The TDS4001P.C uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit that senses overvoltage events and rapidly shunts transient current to ground. Its clamping voltage remains nearly constant due to ultra-low dynamic resistance (<20 mΩ) and FET RDS(on) collapse under surge conditions.
Unlike standard TVS diodes whose clamping voltage rises linearly with peak pulse current (VC = VBR + IPP × RDYN), the TDS4001P.C maintains ~35V clamping from 24A to 40A (1.2/50μs + 8/20μs combo waveform) and across –40°C to +125°C operating temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 40 V - Maximum continuous DC or RMS operating voltage on protected line without device activation. |
| Clamping Voltage | 35 V at 40 A (1.2/50μs + 8/20μs combo, RS = 2 Ω) - Limits transient voltage seen by downstream ICs to safe level during worst-case surge. |
| Peak Pulse Current | 40 A (8/20μs) - Withstands industrial-level lightning surges per IEC 61000-4-5 without failure. |
| ESD Withstand | ±30 kV contact & air (IEC 61000-4-2) - Survives direct human-body ESD events without degradation. |
| Dynamic Resistance | 20 mΩ - Enables flat clamping response and minimizes voltage overshoot during fast-rising transients. |
| Junction Capacitance | 175 pF at 40 V, 1 MHz - Low enough for <100 Mbps data lines but not suitable for USB 3.x or PCIe. |
Pinout & Package
Package: DFN 1.6 mm × 1.6 mm × 0.55 mm, 6-lead, Pb-free, RoHS-compliant, UL 94V-0 molding compound, marked "T40" + date code.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground return path for all surge current; all three pins must be connected to maximize current sharing and minimize parasitic inductance. |
| 4, 5, 6 | IN | Protected line input (e.g., VBUS, DC input); parallel connection of all three pins ensures uniform current distribution and full 40A rating. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies ≤0.5 V across 24–40 A surge range and –40°C to +125°C ambient - eliminates thermal derating uncertainty in industrial designs. |
| FET-based shunt topology | Replaces junction-limited TVS with low-RDS(on) MOSFET, shifting energy dissipation from PN junction to channel - enables higher single-pulse survivability. |
| High EFT immunity | ±4 kV per IEC 61000-4-4 (5/50 ns, 100 kHz/5 kHz bursts) - protects against repetitive switching noise in motor drives and PLC I/O modules. |
| Low leakage | ≤600 nA at 40 V reverse bias - prevents measurable power loss in always-on battery-backed or energy-harvesting systems. |
Applications
| USB PD Input Protection | Industrial Load Switch Front-End |
|---|---|
Use Scenario: Protecting 20–40V USB Power Delivery input rails from connector-induced ESD and lightning-induced surges in portable chargers and docking stations. IC Role / Device Role / Timing Role: Primary EOS shunt suppressor placed directly at Type-C receptacle, clamping transients before they reach PD controller and buck converter. Use Value: Maintains 35V clamping at full 40A surge and 125°C ambient - avoids overvoltage damage to 40V-rated PD controllers where standard TVS would exceed 45V. |
Use Scenario: Safeguarding enable and input pins of high-side load switches (e.g., HS2950P) in programmable logic controllers and remote I/O modules. IC Role / Device Role / Timing Role: Front-end transient barrier preventing EOS from propagating into sensitive gate-drive and current-sense circuitry. Use Value: Limits clamping voltage below 38V - stays within absolute maximum rating of typical 40V load switch VIN and VEN pins, avoiding latch-up or oxide breakdown. |
| 24–40V DC Power Bus Protection | IoT Edge Node Power Input |
Use Scenario: Securing 24V/36V/40V DC inputs in factory automation sensors, HMI panels, and PoE-powered edge devices exposed to long cable runs. IC Role / Device Role / Timing Role: First-line defense against induced surges from nearby motor switching or AC mains coupling onto DC distribution lines. Use Value: Delivers 1120 W peak pulse power handling (40A × 28V) in 1.6 mm² footprint - replaces bulkier 2-lead TVS arrays while improving thermal stability. |
Use Scenario: Protecting battery-charging and adapter-input circuits in battery-powered IoT gateways and smart meters deployed in uncontrolled environments. IC Role / Device Role / Timing Role: Standalone EOS protector for Li-ion charger ICs and PMIC inputs operating up to 40V system voltage. Use Value: Ultra-low 600 nA max leakage at 40V preserves battery life over multi-year deployments; ±30kV ESD rating withstands field service handling. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDS2211P.C | 22V working voltage, 27.5V clamping at 40A, 175 pF capacitance | Optimized for 20–22V USB PD and 24V industrial buses | Select when protecting ≤22V systems requiring lowest possible clamping voltage and minimal capacitance impact. |
| uClamp4511ZA | 45V working voltage, 48V clamping at 30A, 120 pF capacitance, SOD-323 package | Lower capacitance but lower surge rating and larger footprint than DFN-6 | Choose for space-constrained 40–45V applications where <120 pF is mandatory and 30A surge suffices. |
Compared with TDS2211P.C and uClamp4511ZA, the TDS4001P.C uniquely balances 40V operation, 40A surge capability, and DFN-6 compactness - enabling robust protection in 24–40V systems without sacrificing PCB area or thermal margin.

FAQ
What is the maximum continuous operating voltage for TDS4001P.C?
The TDS4001P.C has a reverse stand-off voltage (VRWM) of 40 V, meaning it can continuously block up to 40 V DC or RMS without entering conduction. This makes it suitable for 36V nominal industrial buses and 40V USB PD extended power ranges. Operation above 40 V risks premature triggering and potential degradation of the TDS4001P.C.
How does TDS4001P.C differ from standard TVS diodes in clamping behavior?
Unlike standard TVS diodes whose clamping voltage rises linearly with peak pulse current (VC = VBR + IPP × RDYN), the TDS4001P.C uses a triggered FET shunt that maintains ~35 V clamping from 24A to 40A and across –40°C to +125°C. This eliminates thermal derating uncertainty and ensures predictable protection margins in the TDS4001P.C.
Can TDS4001P.C be used on high-speed data lines like USB 3.2 or PCIe?
No - the TDS4001P.C has 175 pF junction capacitance at 40 V, which introduces excessive signal distortion and insertion loss on >1 Gbps interfaces. It is intended for power lines and low-speed control signals only. For USB 3.2 or PCIe, use low-capacitance TVS such as RClamp3371ZC (<0.25 pF), not the TDS4001P.C.
What is the recommended PCB layout for optimal surge performance of TDS4001P.C?
Place the TDS4001P.C within 2 mm of the protected connector. Connect all three IN pins (4, 5, 6) via a single short, wide trace to the protected line, and tie all three GND pins (1, 2, 3) directly to a solid ground plane using ≥4 vias. Avoid stubs or splits - any impedance discontinuity degrades the TDS4001P.C's ability to clamp fast-rising ESD events.
Is TDS4001P.C RoHS-compliant and halogen-free?
Yes - the TDS4001P.C is Pb-free, halogen-free, and fully compliant with RoHS Directive 2011/65/EU and WEEE Directive 2012/19/EU. Its molding compound meets UL 94V-0 flammability rating, and the lead finish is matte tin, ensuring compatibility with standard SnAgCu reflow profiles used for the TDS4001P.C.
