Product details
Overview
SC600AIMLTRT 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 to safeguard controllers from bus overvoltage.
For engineers reviewing the SC600AIMLTRT datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability under surge, low dynamic resistance (20mΩ), junction capacitance (175pF), and DFN-6 package compatibility with space-constrained industrial and portable designs.
Technical Context
The SC600AIMLTRT uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit upon detection of overvoltage. Unlike conventional TVS diodes, its clamping voltage remains nearly constant across 24–40A surge currents due to decreasing RDS(on) under stress.
It operates over –40°C to +125°C, maintains <600nA reverse leakage at 22V, and achieves 1120W peak pulse power handling. Its functional architecture enables reliable protection for unsymmetrical lines per IEC 61000-4-5 (±1kV, 1.2/50μs + 8/20μs combo wave, RS = 42Ω).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - matches nominal USB PD bus voltage and ensures no false triggering during normal operation. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs) - stays below typical 29–30V damage threshold of USB PD controllers. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 industrial surge immunity requirements. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds system-level ESD robustness targets for consumer and industrial ports. |
| Dynamic Resistance | 20mΩ - enables low-voltage drop during conduction, minimizing energy dissipation in protected ICs. |
| Junction Capacitance | 175pF at 22V, 1MHz - compatible with DC power rails and low-speed signal lines without signal integrity impact. |
| Operating Temperature | –40°C to +125°C - supports deployment in automotive cabin, industrial control, and outdoor IoT environments. |
Pinout & Package
SC600AIMLTRT is housed in a RoHS-compliant DFN-6 package (1.6mm × 1.6mm × 0.55mm) with exposed thermal pad not required-energy is dissipated via FET channel, not junction heating.
| 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 (e.g., VBUS); parallel connection of all three pins ensures uniform current distribution and full 40A rating. |
Key Features
| Feature | Design Value |
|---|---|
| Constant Clamping Architecture | FET-based shunt delivers flat 27.5–28V clamping from 24A to 40A-eliminates voltage rise seen in TVS diodes and simplifies margin analysis. |
| Low Dynamic Resistance | 20mΩ measured between 1A–40A (8/20μs)-reduces voltage overshoot during fast transients and improves downstream component survivability. |
| High-Temperature Stability | Clamping voltage drift <0.5V from –40°C to +125°C-enables reliable protection in thermally aggressive enclosures without derating. |
| Ultra-Low Leakage | Max 600nA at 22V-minimizes standby power loss and avoids interference with high-impedance sensing or bias networks. |
| DFN-6 Space Efficiency | 1.6mm × 1.6mm footprint-saves >60% board area vs. SOT-23 TVS solutions while supporting same or higher surge ratings. |
Applications
| USB Type-C Power Delivery Input Protection | Industrial Load Switch Input Protection |
|---|---|
|
Use Scenario: Protecting 20–22V VBUS lines in USB-C receptacles against lightning-induced surges and connector hot-plug ESD. IC Role / Device Role / Timing Role: Primary EOS shunt suppressor placed directly at connector, diverting transient current to GND before it reaches PD controller or load switch. Use Value: Maintains 28V clamping at full 40A surge-prevents latch-up or gate oxide rupture in USB PD controllers rated for ≤29V absolute max. |
Use Scenario: Safeguarding input terminals of industrial-grade load switches (e.g., HS2950P) in remote meters and robotics. IC Role / Device Role / Timing Role: Front-end transient clamp that limits voltage across the load switch's internal FET drain-source during surge events. Use Value: Keeps VDS below 30V during 1.2/50μs + 8/20μs combo-wave surges-avoids avalanche failure and extends switch lifetime. |
| IoT Device DC Power Rail Protection | Notebook/Tablet Main Power Input Protection |
|
Use Scenario: Securing 22V-rated auxiliary power inputs on battery-powered edge sensors and gateway modules. IC Role / Device Role / Timing Role: Standalone EOS protector on unregulated DC input, operating independently of system MCU or PMIC. Use Value: Delivers ±30kV ESD immunity without requiring active control or external bias-ideal for always-on, low-power systems. |
Use Scenario: Hardening main adapter input (e.g., 20V barrel jack or USB-C port) in thin-client notebooks and detachable tablets. IC Role / Device Role / Timing Role: First-line defense against user-induced ESD and conducted surges entering through AC/DC adapter or docking station. Use Value: 175pF capacitance avoids resonance with input bulk capacitors; DFN-6 placement near connector minimizes trace inductance coupling. |
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-6 package, and identical marking code "T22"; differs only in tape-and-reel packaging (3,000 pcs/reel vs. SC600AIMLTRT's unspecified quantity). | Same use cases: USB-C PD, load switch, IoT power rail protection. | Select TDS2211P.C when standard Semtech reel quantity and date-code traceability are required. |
| uClamp2411ZA | 24V working voltage, lower 24A IPP rating, 0.25pF capacitance-optimized for CC/SBU lines, not power rails. | Limited to low-capacitance data-line protection; unsuitable for 22V VBUS due to lower surge rating and different clamping behavior. | Choose uClamp2411ZA only for auxiliary signal lines-not as a direct replacement for SC600AIMLTRT on power paths. |
Compared with TDS2211P.C, SC600AIMLTRT offers identical protection performance and package but may differ in reel logistics; versus uClamp2411ZA, SC600AIMLTRT provides 67% higher surge current capacity and is engineered specifically for 22V power-line clamping-not signal-line ESD suppression.

FAQ
What is the primary protection function of the SC600AIMLTRT?
The SC600AIMLTRT functions as a Transient Diverting Suppressor that actively shunts high-energy EOS events-including ESD, lightning surges, and EFT-to ground using a precision-triggered FET. Unlike passive TVS diodes, it maintains a stable ~28V clamping voltage across its full 40A surge rating and operating temperature range, making SC600AIMLTRT ideal for protecting sensitive 22V power rails in USB-C PD and industrial systems.
Does the SC600AIMLTRT require a thermal pad on the PCB?
No, the SC600AIMLTRT does not require a thermal pad. Its FET-based architecture dissipates surge energy through channel conduction rather than junction heating, eliminating the need for thermal vias or copper pours beneath the DFN-6 package. Layout guidelines emphasize low-inductance grounding of all three GND pins (1–3) and parallel routing of all three IN pins (4–6), not thermal management-confirmed in Semtech's official datasheet Rev 2.5, page 6.
Can SC600AIMLTRT be used on USB-C SuperSpeed differential pairs?
No, SC600AIMLTRT is not suitable for USB-C SuperSpeed (TX/RX) differential pairs. Its 175pF junction capacitance would severely degrade signal integrity at multi-Gbps rates. Semtech explicitly recommends low-capacitance devices like RClamp3371ZC (<0.25pF) for those lines. SC600AIMLTRT is specified for single-ended 22V power or low-speed I/O lines-its datasheet confirms use on VBUS, CC, and SBU only when paired with appropriate companion devices.
What is the maximum allowable ambient temperature for continuous operation of SC600AIMLTRT?
The SC600AIMLTRT is rated for continuous operation from –40°C to +125°C ambient temperature. Its clamping voltage remains stable across this full range, with less than 0.5V variation observed at 40A surge current (per Figure 3, page 3 of datasheet Rev 2.5). This makes SC600AIMLTRT suitable for under-hood automotive modules, industrial PLCs, and outdoor IoT gateways where thermal cycling and sustained high-temperature operation are expected.
How does SC600AIMLTRT differ from standard TVS diodes in surge response?
Standard TVS diodes exhibit rising clamping voltage with increasing peak pulse current (VC = VBR + IPP × RDYN) and degrade at elevated temperatures. In contrast, SC600AIMLTRT uses a triggered FET whose RDS(on) decreases under surge, delivering flat 27.5–28V clamping from 24A to 40A and minimal drift over –40°C to +125°C. This fundamental architecture difference-documented in the TDS2211P functional description (pages 4–5)-makes SC600AIMLTRT more predictable and robust for mission-critical 22V rail protection.
