Product details
Overview
TDS3011P.C from Semtech is a transient diverting suppressor designed for high-energy EOS protection of 30V-rated I/O or power lines in USB PD, USB Type-C, and industrial equipment. It features ±30kV IEC 61000-4-2 ESD immunity, 40A peak pulse current (8/20μs), 27.5–28V clamping voltage at 40A, 20mΩ dynamic resistance, and 175pF junction capacitance at 22V.
For engineers reviewing the TDS3011P.C datasheet, pinout, applications, or equivalent options, this device offers stable clamping across temperature (−40°C to +125°C) and current (24–40A), solid-state FET-based surge diversion, and DFN 1.6×1.6mm space-efficient packaging - critical for compact, high-reliability bus protection designs.
Technical Context
The TDS3011P.C uses a precision-triggered, surge-rated MOSFET as its primary protection element - not a conventional TVS diode - enabling near-constant clamping voltage independent of peak pulse current magnitude or operating temperature. Its trigger circuit activates the shunt FET when transient voltage exceeds breakdown, leveraging ultra-low RDS(on) to maintain clamping stability.
This architecture eliminates the linear VC = VBR + IPP × RDYN dependency seen in standard TVS devices. Clamping remains ~27.5–28V from −40°C to +125°C and across 24A–40A (8/20μs), with <0.1Ω effective on-resistance during conduction.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 30V - supports protected bus operation up to 30V DC, suitable for USB PD 3.0 (20V nominal + margin) and industrial 24V systems |
| Clamping Voltage | 27.5–28V at 40A (8/20μs) - limits transient overvoltage to safe levels for downstream 30V-tolerant ICs like load switches and PD controllers |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 surge immunity requirements for industrial and USB-C applications |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds Class 4 ESD immunity for front-panel connectors and hot-plug interfaces |
| Junction Capacitance | 175pF at 22V, 1MHz - low enough for USB PD bus protection without signal integrity degradation on DC power lines |
| Dynamic Resistance | 20mΩ - ensures minimal voltage rise under surge current, enabling tight clamping control and thermal efficiency |
| Operating Temperature | −40°C to +125°C - supports deployment in automotive-grade enclosures, industrial edge nodes, and thermally constrained notebooks |
Pinout & Package
Package: DFN 1.6mm × 1.6mm × 0.55mm, 6-lead, Pb-free, RoHS/WEEE compliant, UL 94V-0 molding compound. Marking code "T30" + date code; pin 1 indicated by laser dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground return path for surge current; all three pins must be connected to maximize current handling and minimize parasitic inductance |
| 4, 5, 6 | IN | Protected line input (bus or I/O); all three pins are internally paralleled and must be tied together externally for full 40A rating |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage stays within 27.5–28V across 24–40A and −40°C to +125°C - eliminates derating uncertainty in thermal or high-current designs |
| FET-based shunt protection | Surge energy diverted through low-RDS(on) MOSFET instead of PN-junction dissipation - enables higher surge endurance and lower thermal stress vs. TVS diodes |
| Low dynamic resistance | 20mΩ measured between 1A–40A (8/20μs) - minimizes IR drop during surge, preserving voltage margin for protected ICs |
| High EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns, 100kHz/5kHz) - protects against repetitive fast transients in motor drives and PLC I/O modules |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting the VCONN/VBUS line in USB-C receptacles supporting up to 30V PD 3.1, exposed to lightning-induced surges and hot-plug ESD. IC Role / Device Role / Timing Role: Transient diverting suppressor placed directly at connector entry point to clamp surges before reaching PD controller or load switch. Use Value: Maintains 27.5–28V clamping at 40A and 125°C - prevents damage to 30V-rated controllers (e.g., STUSB4500, CYPD3177) where conventional TVS would exceed safe voltage margins. |
Use Scenario: Safeguarding the input of industrial-grade load switches (e.g., TPS22990, RTQ2132) in remote meters, robotics, and factory automation systems subject to 1kV/42Ω surges. IC Role / Device Role / Timing Role: Primary EOS protection element placed upstream of the load switch to limit transient voltage below its absolute maximum VIN rating. Use Value: Prevents internal FET avalanche failure by clamping to ≤28V - avoids latch-up or permanent gate oxide damage that occurs when standard TVS clamps >32V at elevated temperature. |
| Notebook/Tablet 24V System Rail Protection | IoT Edge Node DC Power Input Protection |
Use Scenario: Securing the 24V auxiliary rail in thin-and-light notebooks and tablets powering SSDs, displays, or USB-C docks, where board space and thermal headroom are constrained. IC Role / Device Role / Timing Role: Compact, low-capacitance (175pF) protector mounted adjacent to the DC jack to intercept fast-rising ESD and switching noise. Use Value: Delivers 40A surge capability in 1.6×1.6mm footprint - replaces larger SOD-123 or SMA packages while maintaining clamping stability across operating temperature range. |
Use Scenario: Hardening the 30V-rated DC input of battery-powered IoT gateways and sensor hubs deployed outdoors or in electrically noisy environments (e.g., smart agriculture, building HVAC). IC Role / Device Role / Timing Role: First-line defense against induced surges from nearby AC wiring, relay switching, or electrostatic discharge on enclosure ports. Use Value: Guarantees ≤28V clamping at −40°C ambient - ensures reliable protection during cold-start conditions where TVS devices exhibit significant VC drift. |
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 | 30V working voltage, 27.5–28V clamping at 40A, 175pF | Optimized for 30V bus protection (e.g., USB PD 3.1, 24V industrial rails) | Select when system operating voltage reaches 30V and clamping margin below 30V ICs is critical |
| uClamp3311ZA | 33V working voltage, 33V clamping at 20A, 120pF, TVS-based | Lower capacitance but higher clamping voltage; no constant-clamp behavior | Consider only if capacitance <120pF is mandatory and clamping above 30V is acceptable for protected ICs |
Compared with TDS2211P.C and uClamp3311ZA, the TDS3011P.C uniquely delivers 30V-rated protection with sub-28V clamping across full temperature and current range - enabling robust design margin for next-generation USB PD and industrial 24V/30V systems where TVS alternatives fail to meet both voltage and thermal constraints.

FAQ
What is the working voltage rating of the TDS3011P.C?
The TDS3011P.C has a reverse stand-off voltage (VRWM) of 30V, meaning it reliably blocks voltages up to 30V DC in normal operation while remaining fully functional. This rating aligns with USB PD 3.1 Extended Power Range (EPR) and industrial 24V/30V bus architectures, ensuring no leakage or premature triggering during steady-state operation.
How does the TDS3011P.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 TDS3011P.C uses a triggered MOSFET to maintain clamping voltage at 27.5–28V across its full 24–40A rating and −40°C to +125°C range - eliminating thermal and current-dependent derating concerns present in PN-junction devices.
Can the TDS3011P.C be used for USB Type-C CC line protection?
No - the TDS3011P.C is rated for 30V operation and optimized for high-current bus protection (e.g., VBUS, VCONN). For CC/SBU lines, Semtech recommends uClamp2411ZA (24V, low-capacitance TVS) due to the CC line's 5V signaling and strict <10pF capacitance requirement; using TDS3011P.C would violate signal integrity and voltage tolerance specs.
What is the recommended PCB layout for optimal performance of the TDS3011P.C?
Place the TDS3011P.C as close as possible to the protected connector. Connect all IN pins (4, 5, 6) via a single short, wide trace; tie all GND pins (1, 2, 3) directly to a solid ground plane using multiple vias. Avoid thermal pads - energy is dissipated in the silicon FET, not the package - and ensure minimal loop area to reduce inductive voltage overshoot during fast transients.
Is the TDS3011P.C RoHS and halogen-free compliant?
Yes - the TDS3011P.C is Pb-free, halogen-free, and fully compliant with RoHS and WEEE directives. Its molding compound meets UL 94V-0 flammability rating, and the lead finish is lead-free, satisfying environmental and safety requirements for global industrial and consumer electronics manufacturing.
