Product details
Overview
SC5010ULTRT from Semtech is a Transient Diverting Suppressor (TDS) designed for high-energy EOS protection of 22V-rated power or I/O lines. It delivers ±30kV IEC 61000-4-2 ESD immunity, 40A peak pulse current (8/20μs), and a stable 27.5–28V clamping voltage across temperature and current range. Used in USB Type-C PD input protection and load switch front-end surge suppression.
For engineers reviewing the SC5010ULTRT datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability under 40A transients, DFN-6 thermal and layout performance, 175pF junction capacitance at 22V, and compatibility with industrial and USB PD systems requiring robust 22V bus protection.
Technical Context
The SC5010ULTRT employs a surge-rated FET as its primary protection element, activated by a precision trigger circuit that senses overvoltage events. Unlike conventional TVS diodes, its clamping voltage remains nearly constant-27.5–28V-across 24A to 40A peak pulse currents due to the FET's ultra-low dynamic resistance (20mΩ).
It operates from −40°C to +125°C with reverse stand-off voltage of 22V and breakdown voltage of 25–27.9V. Its 175pF junction capacitance at 22V and 1MHz makes it suitable for DC power rails and low-speed signal lines where capacitance sensitivity is moderate.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC operating voltage on protected line without leakage or conduction. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs + 1.2/50μs combo wave) - ensures downstream 24V-rated ICs (e.g., USB PD controllers) remain below damage threshold. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 surge immunity for industrial equipment and USB PD inputs. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds Level 4 requirements for handheld and portable electronics interfaces. |
| Junction Capacitance | 175pF at VR = 22V, f = 1MHz - low enough for 22V power rail protection without significant AC loading or signal distortion. |
| Dynamic Resistance | 20mΩ (measured 1A–40A, 8/20μs) - enables flat clamping response and minimizes voltage rise under increasing surge current. |
Pinout & Package
SC5010ULTRT is housed in a Pb-free, RoHS-compliant DFN package measuring 1.6mm × 1.6mm × 0.55mm with 6 leads and UL 94V-0 molding compound.
| 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 sharing and minimize parasitic inductance. |
| 4, 5, 6 | IN | Protected line input terminal; connects directly to VBus or power rail; all three pins are internally tied and must be shorted externally for full 40A rating. |
Key Features
| Feature | Design Value |
|---|---|
| FET-based transient shunt | Replaces traditional TVS with active switching: clamping voltage stays flat across 24–40A, unlike linear VC = VBR + IPP×RDYN behavior. |
| Stable clamping vs. temperature | 27.5–28V clamping maintained from −40°C to +125°C - eliminates derating concerns in automotive or industrial ambient conditions. |
| Low dynamic resistance | 20mΩ enables minimal IR drop during surge, preserving voltage margin for downstream 24V-rated components. |
| High-energy EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns, 5kHz & 100kHz) - protects against repetitive fast transients in motor drives and PLC I/O modules. |
Applications
| USB Type-C Power Delivery Input Protection | Industrial Load Switch Front-End Protection |
|---|---|
Use Scenario: Protecting the VBus line of a USB Type-C port supporting up to 20V/5A PD negotiation, exposed to ESD and lightning-induced surges. IC Role / Device Role / Timing Role: Primary EOS suppressor placed between connector and PD controller or buck converter input. Use Value: Maintains 27.5–28V clamping at 40A and 125°C - prevents overvoltage damage to 24V-rated PD controllers where standard TVS would exceed 35V. |
Use Scenario: Securing the input of an industrial-grade load switch (e.g., HS2950P) powering remote sensors or actuators in metering or robotics. IC Role / Device Role / Timing Role: First-line surge diverter absorbing IEC 61000-4-5 1kV/42Ω transients before they stress the load switch's internal FET. Use Value: Limits voltage across load switch drain-source to ≤28V during 40A surge - avoids gate oxide rupture or thermal runaway in the protected switch. |
| Notebook/Tablet 22V System Rail Protection | IoT Gateway DC Power Input Protection |
Use Scenario: Safeguarding the main 22V system rail in thin-and-light notebooks or tablets against accidental adapter misconnection or ESD coupling. IC Role / Device Role / Timing Role: Standalone rail protector adjacent to DC jack or battery input, coordinating with upstream fuse and downstream PMIC. Use Value: 175pF capacitance avoids destabilizing 22V buck converters; 22V VRWM allows full utilization of rail headroom without leakage penalty. |
Use Scenario: Hardening the 22V DC input of an outdoor IoT gateway subjected to induced surges from nearby lightning or AC mains coupling. IC Role / Device Role / Timing Role: Primary transient suppressor on PoE-derived or wall-adapter-fed 22V input, preceding DC-DC conversion stage. Use Value: 1120W peak pulse power rating handles multi-event surge exposure; DFN-6 footprint saves space in compact gateway enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDS2211P | Same die, identical electrical specs and package; SC5010ULTRT is Semtech's alternate ordering code for TDS2211P. | Identical use cases: USB PD, load switch, 22V rail protection. | Select SC5010ULTRT when sourcing through authorized distributors using this part number; no design or layout changes required. |
| uClamp2411ZA | 24V working voltage, lower 20A IPP rating, higher 33V clamping at 20A, 12pF capacitance. | Better suited for CC/SBU lines in USB-C; not rated for 40A or 22V bus-level protection. | Use only for low-capacitance, low-current auxiliary lines - not a functional replacement for SC5010ULTRT on main power rails. |
Compared with TDS2211P, SC5010ULTRT is a direct manufacturer-confirmed alternate marking with identical performance; versus uClamp2411ZA, it offers 2× peak current handling and 5V lower clamping but trades 163pF higher capacitance - making SC5010ULTRT optimal for robust 22V power rail protection where capacitance is secondary to surge energy absorption.

FAQ
What is the exact package type and dimensions of SC5010ULTRT?
SC5010ULTRT uses a DFN-6 package measuring 1.6mm × 1.6mm × 0.55mm with exposed pad-less construction. Pin 1 is marked by a laser dot; terminals consist of three GND pins (1–3) and three IN pins (4–6), all requiring low-inductance PCB connections for full 40A surge rating. The package is Pb-free, halogen-free, and RoHS/WEEE compliant.
Does SC5010ULTRT meet IEC 61000-4-5 surge immunity standards?
Yes, SC5010ULTRT is rated for 40A peak pulse current under IEC 61000-4-5 8/20μs waveform and supports ±1kV combination wave (1.2/50μs voltage + 8/20μs current, RS = 42Ω), satisfying Level 4 industrial surge immunity requirements. Its 27.5–28V clamping ensures protected circuits remain within safe voltage margins during such events.
How does SC5010ULTRT differ from standard TVS diodes in clamping behavior?
Unlike standard TVS diodes whose clamping voltage rises linearly with surge current (VC = VBR + IPP×RDYN), SC5010ULTRT uses a triggered FET architecture that maintains near-constant clamping (27.5–28V) from 24A to 40A. This results from sub-20mΩ dynamic resistance and eliminates thermal derating issues seen in junction-based TVS devices.
Can SC5010ULTRT be used on USB SuperSpeed differential pairs?
No, SC5010ULTRT is not suitable for USB SuperSpeed (TX/RX) lines due to its 175pF junction capacitance, which would severely degrade signal integrity. For those lines, Semtech recommends low-capacitance devices like RClamp3371ZC (<0.25pF). SC5010ULTRT is intended for VBus, CC, SBU, or power rail protection only.
What is the maximum operating temperature range for SC5010ULTRT?
SC5010ULTRT is specified for continuous operation from −40°C to +125°C ambient temperature. Its clamping voltage remains stable across this full range - measured at 27.5–28V at 40A even at +125°C - making it suitable for under-hood automotive modules, industrial controls, and thermally constrained portable electronics where thermal derating is critical.
