Product details
Overview
SC600CIMLTRT from Semtech is a Transient Diverting Suppressor (TDS) designed for high-energy EOS protection of 22V-rated power or I/O lines, featuring ±30kV IEC 61000-4-2 ESD immunity, 40A peak pulse current (8/20μs), 27.5–28V clamping voltage at 40A, and 20mΩ dynamic resistance. It protects USB PD, USB Type-C VBus, and load switch inputs in industrial and portable electronics.
For engineers reviewing the SC600CIMLTRT datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, DFN-6 package layout guidance, real-world clamping stability across temperature and current, and validated alternatives for 22V bus protection design.
Technical Context
The SC600CIMLTRT uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit that turns on the shunt path when transient voltage exceeds breakdown. Unlike conventional TVS diodes, its clamping voltage remains nearly constant - 27.5–28V - across 24A to 40A peak pulse current and from –40°C to +125°C.
This behavior stems from the FET's decreasing RDS(on) under surge, yielding ultra-low dynamic resistance (20mΩ) and eliminating the linear VC = VBR + IPP × RDYN dependency seen in junction-based TVS devices. The device is rated for 1120W peak pulse power and meets IEC 61000-4-4 (±4kV EFT) and IEC 61000-4-5 (±1kV, 1.2/50μs) standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC or RMS operating voltage on protected line without leakage or conduction. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs + 1.2/50μs combo wave, RS = 2Ω) - ensures downstream 24V-rated ICs (e.g., USB PD controllers) remain below damage threshold during surge. |
| Peak Pulse Current | 40A (8/20μs) - supports industrial-level surge immunity per IEC 61000-4-5, enabling use in harsh environments without derating. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds common system-level ESD requirements for consumer and industrial ports. |
| Dynamic Resistance | 20mΩ - enables stable clamping independent of current magnitude, critical for predictable protection margin across load conditions. |
| Junction Capacitance | 175pF at 22V, 1MHz - low enough for 22V power rail protection; not suitable for high-speed data lines (requires separate <0.25pF TVS). |
Pinout & Package
SC600CIMLTRT is housed in a Pb-free, RoHS-compliant DFN-6 package measuring 1.6mm × 1.6mm × 0.55mm with exposed thermal pad (no internal thermal pad required; energy dissipated in silicon). All six pins must be connected for full 40A surge rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground return path for surge current; all three must be soldered to PCB ground plane with multiple vias to minimize inductance. |
| Pins 4, 5, 6 | IN | Protected line input (e.g., USB PD VBus); all three pins are internally paralleled and must be connected in a single low-inductance trace to the connector. |
Key Features
| Feature | Design Value |
|---|---|
| Constant clamping over current range | 27.5–28V from 24A to 40A - eliminates need for oversized IPP margin to meet voltage safety limits. |
| Stable clamping over temperature | No increase in VC from –40°C to +125°C - enables reliable protection in uncontrolled thermal environments (e.g., industrial enclosures). |
| Low dynamic resistance | 20mΩ - reduces IR drop during surge, preserving voltage headroom for downstream regulators and switches. |
| High-energy surge handling | 1120W peak pulse power - supports repeated lightning-surge events without degradation, unlike standard TVS diodes. |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting the 20V–22V VBus line in USB Type-C ports supporting Power Delivery up to 100W. IC Role / Device Role / Timing Role: Primary EOS suppressor placed between Type-C receptacle and PD controller or load switch. Use Value: Maintains 27.5–28V clamping at 40A and 125°C - prevents PD controller latch-up or gate oxide damage where conventional TVS would exceed 35V. |
Use Scenario: Safeguarding the input of high-side load switches (e.g., HS2950P) in remote meters, robotics, and IoT edge nodes. IC Role / Device Role / Timing Role: Front-end transient shunt that diverts surge before it reaches the load switch's internal FET drain. Use Value: Clamps below the 30V absolute maximum rating of typical 24V-rated load switches, preventing catastrophic failure during 1kV surge events. |
| Storage Device Power Rail Protection | Notebook/Tablet Main Power Input Protection |
Use Scenario: Securing 19V–22V input rails in NVMe SSD enclosures and external HDD docks exposed to hot-plug transients. IC Role / Device Role / Timing Role: Standalone transient suppressor on main DC input prior to DC-DC conversion stage. Use Value: 40A surge rating and 1120W peak power handling ensure robustness against repeated insertion-induced spikes without parameter drift. |
Use Scenario: Protecting 20V system input in ultrabooks and tablets where space-constrained layouts demand minimal footprint protection. IC Role / Device Role / Timing Role: Compact DFN-6 (1.6×1.6mm) EOS suppressor mounted directly at barrel jack or USB-C port. Use Value: 1.6mm × 1.6mm footprint saves >60% board area versus SO-8 TVS solutions while delivering superior clamping performance. |
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, identical marking (T22), same reel quantity (3,000 pcs/reel); minor suffix variation reflects Semtech internal revision control. | No functional difference; used interchangeably in production BOMs per Semtech ordering documentation. | Select TDS2211P.C when sourcing directly from Semtech or authorized distributors with full traceability to Rev 2.5 datasheet. |
| uClamp2411ZA | 24V working voltage, lower 20A IPP rating, higher 30V clamping at 20A, smaller 0.65mm × 0.65mm DFN-2 package, 12pF capacitance. | Targeted at CC/SBU lines in USB-C, not VBus; unsuitable for 40A surge or 22V power rail due to lower IPP and higher VC. | Choose uClamp2411ZA only for low-capacitance, low-current signal-line protection - not as a replacement for SC600CIMLTRT in power-rail roles. |
Compared with TDS2211P.C (identical function and form) and uClamp2411ZA (lower-power signal-line variant), SC600CIMLTRT delivers verified 40A/22V/28V performance in a standardized DFN-6 footprint, making it the sole fit for high-energy 22V bus protection where clamping stability and surge endurance are non-negotiable.

FAQ
What is the maximum continuous operating voltage for SC600CIMLTRT?
The SC600CIMLTRT has a reverse stand-off voltage (VRWM) of 22V, meaning it can continuously block up to 22V DC or RMS without significant leakage or conduction. This makes SC600CIMLTRT suitable for protecting 20V–22V power rails such as USB PD VBus, industrial 24V inputs, and notebook adapter inputs where sustained voltage must be tolerated without activation.
Does SC600CIMLTRT require a thermal pad on the PCB?
No, SC600CIMLTRT does not require an external thermal pad. Its DFN-6 package dissipates surge energy within the silicon die during transient events, and the datasheet explicitly states "no thermal pad is needed." Instead, robust grounding via all three GND pins (1, 2, 3) with multiple vias to the ground plane is essential to minimize inductance and ensure full 40A surge capability.
How does SC600CIMLTRT 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), SC600CIMLTRT maintains a near-constant 27.5–28V clamping voltage from 24A to 40A and across –40°C to +125°C. This results from its FET-based architecture and 20mΩ dynamic resistance, delivering predictable protection margins where traditional TVS devices would exceed safe voltage thresholds.
Can SC600CIMLTRT be used on high-speed data lines like USB SuperSpeed or PCIe?
No, SC600CIMLTRT is not suitable for high-speed data lines. With 175pF junction capacitance at 22V, it would severely degrade signal integrity on differential pairs operating above ~100MHz. SC600CIMLTRT is intended exclusively for power rail or low-speed I/O protection. For USB SS, DP/DM, or PCIe lanes, low-capacitance TVS devices such as RClamp3371ZC (<0.25pF) must be used instead.
What is the recommended PCB layout for SC600CIMLTRT to achieve full 40A rating?
To achieve the full 40A peak pulse current rating, SC600CIMLTRT requires all three IN pins (4, 5, 6) to be connected via a single short, wide trace to the protected line (e.g., USB-C VBus pin), and all three GND pins (1, 2, 3) to be connected with multiple vias to an inner-layer ground plane. Placement must be within 5mm of the connector, and no thermal relief should be used on GND pins - direct copper connection is mandatory to minimize parasitic inductance.
