Product details
Overview
SC5014AMLTRT 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 its full current and temperature range (−40°C to +125°C). It is used in USB Type-C power delivery input protection where low, temperature-invariant clamping is critical to safeguard PD controllers.
For engineers reviewing the SC5014AMLTRT datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability over temperature, dynamic resistance (<20 mΩ), junction capacitance (175 pF), and DFN 1.6×1.6mm 6-lead layout compatibility with high-density USB PD and industrial load switch designs.
Technical Context
The SC5014AMLTRT uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit that senses transient overvoltage. Unlike conventional TVS diodes, its clamping voltage remains nearly constant because the FET's RDS(on) decreases with rising current-yielding <20 mΩ dynamic resistance at 40A.
It operates across −40°C to +125°C with no degradation in clamping performance: VC stays within 27.5–28V from IPP = 24A to 40A and across full temperature range. Its 175 pF junction capacitance at 22V/1MHz and 130–600 nA reverse leakage support robust signal integrity on 22V bus lines without excessive loading.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22 V - Matches nominal USB PD bus voltage and ensures reliable standoff during normal operation. |
| Clamping Voltage | 27.5–28 V at 40A (8/20μs + 1.2/50μs combo wave) - Remains stable across temperature and current, protecting downstream ICs below their absolute max rating. |
| Peak Pulse Current | 40 A (8/20μs) - Meets IEC 61000-4-5 Level 4 surge immunity for industrial and USB PD applications. |
| ESD Withstand | ±30 kV contact & air (IEC 61000-4-2) - Exceeds automotive and industrial ESD requirements without derating. |
| Dynamic Resistance | 20 mΩ - Enables low-voltage drop under surge, minimizing energy dissipation in the device and reducing thermal stress. |
| Junction Capacitance | 175 pF at 22 V, 1 MHz - Low enough to avoid signal distortion on 22V power rails while maintaining effective surge conduction. |
Pinout & Package
SC5014AMLTRT is housed in a RoHS-compliant, halogen-free DFN package measuring 1.6 mm × 1.6 mm × 0.55 mm with six leads and UL 94V-0 molding compound. The package supports high-density placement adjacent to connectors and features exposed thermal pad-less construction optimized for surge energy dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground terminals - all three must be connected to maximize surge current path and minimize inductance. |
| 4, 5, 6 | IN | Protected line input - tied together to the 22V bus or power rail; parallel connection increases current handling and reduces impedance. |
Key Features
| Feature | Design Value |
|---|---|
| Constant clamping voltage | 27.5–28 V across 24–40A and −40°C to +125°C - eliminates need for derating at high ambient temperatures. |
| FET-based shunt architecture | Surge-rated MOSFET + precision trigger circuit - achieves <20 mΩ dynamic resistance vs. fixed RDYN in TVS diodes. |
| Low leakage current | 130–600 nA at 22 V - minimizes standby power loss and avoids false triggering in always-on systems. |
| High EFT immunity | ±4 kV per IEC 61000-4-4 (5/50 ns, 5 kHz & 100 kHz) - protects against repetitive fast transients in industrial control environments. |
Applications
| USB Type-C Power Delivery Input Protection | Industrial Load Switch Input Protection |

Use Scenario: Protecting 22V backup power inputs in enterprise SSDs or NAS enclosures subject to hot-plug and system-level surges. IC Role / Device Role / Timing Role: Standoff-and-clamp protector on the backup VCC rail upstream of buck converters and flash memory power management. Use Value: Stable clamping prevents overvoltage latch-up in storage controllers during surge events, preserving data integrity and enabling graceful shutdown. |
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 | Identical electrical specs, same DFN 1.6×1.6mm package, identical marking (T22XX), and same tape-and-reel packaging (3,000 pcs/reel). | No functional difference - TDS2211P.C is the official Semtech orderable part number; SC5014AMLTRT is a valid alternate marking used in distribution channels. | Select TDS2211P.C when sourcing directly from Semtech or authorized distributors requiring exact manufacturer PN traceability. |
| uClamp2411ZA | 24V working voltage, lower 20A IPP rating, higher 33V clamping, and smaller 0.6×0.6mm 2-pin SOD-523 package. | Targeted at CC/SBU lines in USB-C-not suitable for 22V power rail protection due to lower surge rating and higher clamping. | Use only for low-current, low-capacitance signal-line protection; not a functional replacement for SC5014AMLTRT in power rail roles. |
Compared with TDS2211P.C, SC5014AMLTRT is electrically and physically identical-differing only in marking and distribution channel labeling. Compared with uClamp2411ZA, SC5014AMLTRT provides 2× higher surge current, 5V lower clamping, and 3× larger thermal mass, making it suitable for primary 22V bus protection rather than auxiliary signal lines.

FAQ
What is the clamping voltage of SC5014AMLTRT at 40A surge current?
The SC5014AMLTRT clamps at 27.5–28 V under a 40A peak pulse current (8/20μs + 1.2/50μs combination waveform, RS = 2 Ω), and this value remains stable across −40°C to +125°C. This performance is enabled by its FET-based architecture, which maintains low dynamic resistance instead of relying on fixed-junction characteristics like traditional TVS diodes. The SC5014AMLTRT datasheet confirms this clamping behavior is guaranteed by design.
Is SC5014AMLTRT pin-compatible with standard TVS diodes in DFN packages?
No-SC5014AMLTRT uses a unique 6-pin DFN configuration with three GND pins (1–3) and three IN pins (4–6) that must be paralleled for full 40A rating. Standard 2-pin or 3-pin TVS diodes cannot replicate this layout or current-sharing capability. Replacing a TVS with SC5014AMLTRT requires PCB redesign to accommodate the 1.6×1.6mm 6-lead footprint and dual-terminal routing. The SC5014AMLTRT pinout is defined in Semtech's official documentation and verified in application schematics.
Does SC5014AMLTRT require a thermal pad on the PCB?
No-SC5014AMLTRT does not require an exposed thermal pad. Its DFN package dissipates surge energy through the copper traces connected to pins 1–3 (GND) and 4–6 (IN), and Semtech explicitly states "no thermal pad is needed" in the datasheet. Layout best practices emphasize low-inductance grounding via multiple vias and short, wide traces-especially critical for ESD rise-time performance. This design choice simplifies assembly and improves reliability in space-constrained USB PD layouts using SC5014AMLTRT.
Can SC5014AMLTRT protect bidirectional signal lines like USB DP/DM?
No-SC5014AMLTRT is a unidirectional suppressor rated for 22V working voltage on a single polarity rail (IN-to-GND). It is not designed for bidirectional data lines such as USB DP/DM or PCIe lanes, which require sub-0.3pF capacitance and symmetrical ±VBR clamping. For those interfaces, Semtech recommends RClamp3371ZC (0.18pF) or similar low-capacitance TVS arrays. SC5014AMLTRT is intended exclusively for 22V power or unidirectional I/O line protection, as confirmed in its functional diagram and application notes.
What is the junction capacitance of SC5014AMLTRT and how does it affect 22V rail performance?
The SC5014AMLTRT exhibits 175 pF junction capacitance at 22 V and 1 MHz, measured with reverse bias. This value is optimized for 22V power rail protection: low enough to avoid significant AC loading or resonance with typical bulk capacitance (e.g., 10–100 μF), yet high enough to ensure low-impedance surge shunting. In USB PD and industrial load switch applications, this capacitance introduces negligible ripple or delay-unlike signal-line suppressors where sub-pF values are mandatory. The SC5014AMLTRT datasheet specifies this parameter under defined test conditions and confirms its stability across temperature.
