Product details
Overview
SC600DIMSTRT from Semtech is a Transient Diverting Suppressor (TDS) designed for high-energy EOS protection of 22V-rated I/O or power lines, featuring ±30kV IEC 61000-4-2 ESD immunity, 40A peak pulse current (8/20μs), 27.5–28V clamping voltage at 40A, and ultra-low 20mΩ dynamic resistance. It protects USB Type-C power delivery buses, load switch inputs, and industrial interfaces where stable clamping across temperature and current is critical.
For engineers reviewing the SC600DIMSTRT datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, DFN-6 package layout guidance, real-world USB PD and load switch protection use cases, and validated alternative parts with documented functional trade-offs.
Technical Context
The SC600DIMSTRT uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit that senses overvoltage events and rapidly shunts transient current to ground. Unlike conventional TVS diodes, its clamping voltage remains nearly constant - 27.5–28V across 24–40A and −40°C to +125°C - due to decreasing RDS(on) under surge conditions.
It operates with a 22V reverse stand-off voltage (VRWM), 25–27.9V breakdown (VBR), and only 130–600nA leakage at VRWM. Its 175pF junction capacitance at 22V/1MHz and 0.5V forward voltage support low-distortion signal integrity in high-speed bus protection applications.
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, RS=2Ω) - ensures downstream ICs (e.g., USB PD controllers) remain below damage threshold during worst-case surges. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 industrial surge immunity requirements for 22V systems. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds automotive and industrial ESD robustness standards for connector-facing protection. |
| Dynamic Resistance | 20mΩ - enables flat clamping curve and minimizes voltage overshoot during fast-rising transients. |
| Junction Capacitance | 175pF at 22V/1MHz - low enough for USB Type-C VBUS protection without degrading power delivery signaling integrity. |
Pinout & Package
SC600DIMSTRT is housed in a Pb-free, RoHS-compliant DFN-6 package measuring 1.6mm × 1.6mm × 0.55mm with UL 94V-0 molding compound. All six terminals are surface-mount; no thermal pad required - energy dissipation occurs within the silicon FET structure.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground return path for surge current; all three must be connected with low-inductance vias to maximize 40A handling capability. |
| 4, 5, 6 | IN | Protected line input (e.g., USB PD VBUS, load switch VIN); all three pins are internally paralleled and must be shorted externally for full rating. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies <0.5V across 24–40A and −40°C to +125°C - eliminates derating uncertainty in thermal design. |
| FET-based shunt topology | Replaces traditional TVS junctions with a low-RDS(on) MOSFET, reducing thermal stress and enabling higher surge endurance per mm². |
| Low dynamic resistance | 20mΩ measured between 1A–40A (8/20μs) - suppresses voltage overshoot during sub-microsecond ESD events better than TVS diodes. |
| High EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns, 5kHz & 100kHz bursts) - protects against repetitive switching noise in industrial motor drives and PLCs. |
Applications
| USB Type-C Power Delivery Protection | Load Switch Input Protection |
|---|---|
|
Use Scenario: Protecting the VBUS line of a USB Type-C port supporting up to 20V/5A PD negotiation against lightning-induced surges and hot-plug ESD. IC Role / Device Role / Timing Role: Primary EOS shunt protector placed directly at the connector, diverting >40A transients before they reach the PD controller or e-fuse. Use Value: Maintains 27.5–28V clamping across full temperature range - avoids overvoltage damage to 24V-tolerant PD controllers even at 125°C ambient. |
Use Scenario: Safeguarding the input of an industrial-grade load switch (e.g., HS2950P) exposed to 1kV/42Ω surges in remote metering or robotics systems. IC Role / Device Role / Timing Role: Front-end transient limiter that clamps input voltage below the internal FET's absolute maximum VDS rating during surge events. Use Value: Prevents latch-up or gate oxide rupture in the load switch by limiting peak input voltage to ≤28V regardless of surge amplitude up to 40A. |
| Industrial IoT Sensor Hub Protection | Notebook/Tablet VBUS Line Protection |
|
Use Scenario: Shielding 22V auxiliary power rails in edge AI gateways or smart factory sensors from EFT bursts and cable discharge events. IC Role / Device Role / Timing Role: Single-device solution for unsymmetrical line protection with minimal board space (1.6×1.6mm footprint). Use Value: Delivers ±4kV EFT and ±30kV ESD immunity without requiring multi-stage protection networks or PCB area-consuming TVS arrays. |
Use Scenario: Securing the main power rail in ultraportable notebooks and tablets where USB-C charging introduces 20V+ VBUS exposure. IC Role / Device Role / Timing Role: Compact, low-capacitance (175pF) protector co-located with the USB-C receptacle to minimize trace inductance. Use Value: Enables compliance with IEC 61000-4-5 Level 3 (±1kV) while preserving PD communication integrity via stable clamping and minimal parasitic loading. |
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 (T22XX), and fully compatible pinout - direct manufacturer-recommended replacement. | No functional difference; used interchangeably in USB PD and industrial designs per Semtech documentation. | Select TDS2211P.C when sourcing from authorized Semtech distributors with full traceability and tape-and-reel packaging (3,000 pcs/reel). |
| uClamp2411ZA | 24V working voltage, lower 20A IPP rating, higher 33V clamping at 20A, and smaller 0.65×0.65mm DFN-2 package - not rated for 40A or ±1kV/42Ω surges. | Targeted at CC/SBU lines in USB-C, not VBUS; insufficient for load switch input protection requiring 40A handling. | Choose uClamp2411ZA only for low-energy signal-line protection; avoid for SC600DIMSTRT's 22V power rail use cases. |
Compared with SC600DIMSTRT, TDS2211P.C offers identical performance and drop-in compatibility, while uClamp2411ZA serves a different application tier - it lacks the 40A surge rating and stable 28V clamping needed for VBUS or load switch protection, making it unsuitable as a functional substitute.

FAQ
What is the maximum continuous operating voltage for SC600DIMSTRT?
The SC600DIMSTRT has a reverse stand-off voltage (VRWM) of 22V, meaning it can continuously block up to 22V DC without significant leakage or conduction. This makes it suitable for protecting 20V USB PD VBUS lines and other 22V-rated power rails. Exceeding 22V may cause premature conduction and accelerated degradation of the device.
Does SC600DIMSTRT require a thermal pad on the PCB?
No, SC600DIMSTRT does not require a thermal pad. Its DFN-6 package dissipates surge energy internally via the silicon FET structure rather than through junction-to-board conduction. The datasheet explicitly states "no thermal pad is needed," and layout guidelines emphasize low-inductance ground vias instead of thermal relief patterns.
Can SC600DIMSTRT be used to protect high-speed data lines like USB SuperSpeed?
No, SC600DIMSTRT is not intended for high-speed data line protection. With 175pF junction capacitance, it is optimized for VBUS and power rail protection - not signal integrity-critical lanes. For USB SS TX/RX lines, Semtech recommends low-capacitance devices like RClamp3371ZC (<0.25pF). Using SC600DIMSTRT on data lines would severely degrade signal rise/fall times and eye diagrams.
How does SC600DIMSTRT's clamping behavior differ from standard TVS diodes?
Unlike standard TVS diodes - whose clamping voltage rises linearly with peak pulse current (VC = VBR + IPP × RDYN) - SC600DIMSTRT maintains near-constant clamping (27.5–28V) from 24A to 40A due to its FET-based shunt architecture and decreasing RDS(on). This eliminates thermal derating uncertainty and improves protection margin at elevated temperatures.
Is SC600DIMSTRT compliant with RoHS and halogen-free standards?
Yes, SC600DIMSTRT is Pb-free, halogen-free, and fully compliant with RoHS and WEEE directives. Its molding compound carries a UL 94V-0 flammability rating, and the lead finish is lead-free. These compliance attributes are confirmed in the mechanical characteristics section of the official Semtech TDS2211P datasheet (Rev 2.5, Nov 2021), which applies identically to SC600DIMSTRT.
