Product details
Overview
SC600CIMSTRT 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, 20mΩ dynamic resistance, and 175pF junction capacitance. It protects USB PD, USB Type-C VBus, and load switch inputs in industrial and portable electronics.
For engineers reviewing the SC600CIMSTRT datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, DFN-6 package layout guidance, temperature-stable clamping behavior, and direct alternatives for EOS-critical bus protection designs.
Technical Context
The SC600CIMSTRT employs 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 across 24–40A (8/20μs) due to decreasing RDS(on) under surge conditions.
It operates over –40°C to +125°C with stable 27.5–28V clamping at rated current, 130–600nA reverse leakage at 22V, and 1120W peak pulse power handling. Its functional architecture decouples clamping performance from temperature drift and current magnitude-enabling predictable protection in USB PD and industrial power rail applications.
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) - ensures downstream ICs (e.g., USB PD controllers) remain below damage threshold during surge events. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 surge immunity for industrial equipment and USB PD interfaces. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds automotive and industrial ESD requirements without degradation. |
| Dynamic Resistance | 20mΩ - enables low-voltage drop during high-current transients, minimizing energy dissipation in the device itself. |
| Junction Capacitance | 175pF at 22V, 1MHz - compatible with 20V USB PD bus lines where excessive capacitance would distort signaling. |
Pinout & Package
SC600CIMSTRT is housed in a Pb-free, RoHS-compliant DFN-6 package measuring 1.6mm × 1.6mm × 0.55mm with exposed thermal pad not required. All six terminals are electrically active: three parallel input pins and three parallel ground pins for low-inductance surge current routing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1, 2, 3 | GND | Common ground return path for surge current; all three must be connected to minimize inductance and maximize 40A capability. |
| Pin 4, 5, 6 | IN | Parallel-connected input terminals tied to protected bus (e.g., USB PD VBus); equal current sharing reduces localized heating. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies ≤0.5V across 24–40A (8/20μs) and –40°C to +125°C - eliminates derating uncertainty in thermal design. |
| FET-based shunt topology | Replaces PN-junction TVS with low-RDS(on) MOSFET - dissipates surge energy in channel rather than junction, improving reliability under repeated stress. |
| Low dynamic resistance | 20mΩ measured between 1A–40A - reduces voltage overshoot during fast-rising transients (e.g., ESD) compared to TVS diodes with fixed RDYN. |
| High-energy surge rating | 1120W peak pulse power (8/20μs) - supports robust protection in industrial 24V systems and USB PD 20V/3A+ applications. |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting the VBus line in USB Type-C connectors supporting up to 20V/5A PD profiles against lightning-induced surges and connector hot-plug ESD. IC Role / Device Role / Timing Role: Primary EOS shunt protector placed adjacent to the Type-C receptacle, clamping transients before they reach the PD controller or buck converter. Use Value: Maintains 27.5–28V clamping across temperature and current range - avoids overvoltage damage to 24V-tolerant PD controllers while enabling compact layout. |
Use Scenario: Safeguarding the input of high-side load switches (e.g., HS2950P) in remote meters, robotics, and IoT gateways exposed to 42Ω/0.5μF surge coupling. IC Role / Device Role / Timing Role: Front-end transient suppressor that limits voltage seen by the load switch's internal FET drain, preventing avalanche failure during 1kV surges. Use Value: 40A surge rating and stable clamping ensure the load switch remains within safe SOA - eliminating need for oversized external TVS or redundant protection stages. |
| Notebook/Tablet DC Power Input Protection | Industrial Equipment 24V Rail Protection |
Use Scenario: Securing the main DC input rail (e.g., 19.5V adapter input) in thin-client notebooks and tablets against accidental AC mains coupling or ESD from user ports. IC Role / Device Role / Timing Role: Standalone transient diverter placed at board edge, directly shunting surge energy to chassis ground before entering PMIC or battery charger IC. Use Value: 175pF capacitance avoids signal integrity issues on low-frequency power rails, while ±30kV ESD rating covers rigorous IEC 61000-4-2 system-level testing. |
Use Scenario: Protecting 24V auxiliary power rails in programmable logic controllers (PLCs), motor drives, and factory automation I/O modules subjected to long cable runs. IC Role / Device Role / Timing Role: High-energy clamping device installed at terminal block entry point to divert induced lightning surges (IEC 61000-4-5) away from sensitive analog front-ends and microcontrollers. Use Value: Stable 28V clamping at full 40A ensures downstream 3.3V/5V regulators and ADCs remain undamaged - even at 125°C ambient in enclosed 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.C | Identical electrical specs, same DFN-6 package, identical marking (T22), and shared Semtech datasheet Rev 2.5 - confirmed pin-to-pin and functionally identical. | No difference; qualified for same USB PD, industrial, and computing applications per Semtech documentation. | Select TDS2211P.C when requiring traceable lot history or distributor-specific packaging (3,000/reel, 7″ reel). |
| SP1003-01FTG | Lower 30A IPP rating, higher 33V clamping at 30A, 12pF capacitance - uses standard TVS diode architecture with voltage-dependent RDYN. | Suitable only for lower-energy 22V applications where temperature stability and sub-30V clamping are not critical. | Choose SP1003-01FTG only if ultra-low capacitance (<15pF) is prioritized over clamping precision and thermal stability. |
Compared with SC600CIMSTRT, TDS2211P.C offers identical protection performance and layout compatibility, while SP1003-01FTG trades clamping accuracy and temperature stability for reduced capacitance - making SC600CIMSTRT the preferred choice for USB PD and industrial 22V bus protection where consistent voltage limiting is mandatory.

FAQ
What is the exact package type and dimensions of SC600CIMSTRT?
SC600CIMSTRT uses a 6-pin DFN package measuring 1.6mm × 1.6mm × 0.55mm with no exposed thermal pad. Pins 1–3 are GND; pins 4–6 are IN. The land pattern follows Semtech's recommended footprint with 0.5mm pitch and 0.3mm pad width. This compact size enables placement directly at USB Type-C connectors or industrial terminal blocks without sacrificing surge performance.
Does SC600CIMSTRT meet IEC 61000-4-5 surge immunity standards?
Yes, SC600CIMSTRT is rated for 40A peak pulse current using the 8/20μs waveform per IEC 61000-4-5, and also supports ±1kV combination wave (1.2/50μs voltage, 8/20μs current, RS = 42Ω) for unsymmetrical lines. Its 27.5–28V clamping at 40A ensures protected circuits remain within safe operating area during standardized surge testing.
How does SC600CIMSTRT differ from traditional TVS diodes in clamping behavior?
Unlike TVS diodes whose clamping voltage rises linearly with current (VC = VBR + IPP × RDYN), SC600CIMSTRT maintains near-constant clamping (27.5–28V) from 24A to 40A due to its FET-based shunt architecture. Its dynamic resistance drops with increasing current, yielding superior voltage control across temperature and surge magnitude - critical for protecting 24V-tolerant USB PD controllers.
Can SC600CIMSTRT be used for USB Type-C CC or SBU line protection?
No, SC600CIMSTRT is not suitable for CC or SBU line protection because its 175pF junction capacitance would severely degrade high-speed signaling integrity on those differential pairs. For CC/SBU, Semtech recommends uClamp2411ZA (24V, <10pF). SC600CIMSTRT is intended exclusively for VBus or power rail protection where capacitance is non-critical.
What is the maximum operating temperature range for SC600CIMSTRT?
SC600CIMSTRT is specified for continuous operation from –40°C to +125°C ambient. Its clamping voltage remains stable across this full range - varying less than 0.5V at 40A - and junction temperature is rated to +150°C. This makes SC600CIMSTRT suitable for sealed industrial enclosures and automotive under-hood environments where thermal derating of conventional TVS devices would otherwise limit surge capability.
