Product details
Overview
SC600AIMSTRT 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 and Type-C VBus inputs in industrial and portable electronics.
For engineers reviewing the SC600AIMSTRT datasheet, pinout, applications, or equivalent options, key selection criteria include clamping stability across temperature and current, low dynamic resistance for minimal voltage overshoot, DFN-6 footprint compatibility, and compliance with IEC 61000-4-2/4-4/4-5 standards in compact 1.6×1.6mm layouts.
Technical Context
The SC600AIMSTRT 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 - from 24A to 40A and across −40°C to +125°C due to decreasing RDS(on) under surge.
It operates with reverse stand-off voltage of 22V, breakdown voltage of 25–27.9V, and junction capacitance of 175pF at 22V/1MHz. Its 6-pin DFN package integrates three parallel input terminals (pins 4–6) and three ground terminals (pins 1–3), requiring all six pins to be connected for full 40A rating and optimal thermal/surge performance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC bus voltage it can protect without leakage or degradation |
| Clamping Voltage | 27.5–28V at 40A (8/20μs) - ensures protected 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 |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds smartphone/tablet ESD robustness requirements |
| Dynamic Resistance | 20mΩ - enables flat clamping curve and minimizes voltage rise under increasing surge current |
| Junction Capacitance | 175pF at 22V/1MHz - low enough for 20V power rail protection without signal integrity impact |
| Operating Temp | −40°C to +125°C - supports automotive-grade ambient operation in industrial and mobile equipment |
Pinout & Package
SC600AIMSTRT is housed in a Pb-free, RoHS-compliant DFN-6 package measuring 1.6mm × 1.6mm × 0.55mm with UL 94V-0 molding compound. The package features exposed thermal pad-less construction; energy dissipation occurs within the silicon FET structure.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground return path - all three must be connected to minimize inductance and maximize surge current handling |
| Pins 4, 5, 6 | IN | Parallel-connected input terminals for protected line - all three required to achieve rated 40A peak pulse capability |
Key Features
| Feature | Design Value |
|---|---|
| FET-based transient shunting | Replaces traditional TVS diodes with active switching - delivers stable clamping independent of current or temperature |
| Constant clamping across IPP range | 27.5–28V from 24A to 40A - eliminates need for overrating to maintain safe voltage margins |
| Low dynamic resistance | 20mΩ - reduces voltage overshoot during fast-rising transients and improves system-level surge margin |
| High EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns) - protects against repetitive burst noise in industrial control environments |
| Compact DFN-6 footprint | 1.6mm × 1.6mm - saves >50% board area vs. SOT-23 or SOIC alternatives while maintaining 40A rating |
Applications
| USB Type-C Power Delivery | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting 20V VBus lines in USB-C ports supporting up to 100W PD negotiation. IC Role / Device Role / Timing Role: Primary EOS suppressor placed directly at connector, clamping surges before reaching PD controller and load switch. Use Value: Maintains 27.5–28V clamping across −40°C to +125°C - prevents false OVP trips and ensures reliable PD communication under thermal stress. |
Use Scenario: Safeguarding input rails of industrial e-fuses and load switches (e.g., HS2950P) exposed to lightning-induced surges. IC Role / Device Role / Timing Role: Front-end transient shunt that diverts 40A surges away from sensitive internal FETs and gate drivers. Use Value: Clamping voltage stays below 28V - avoids gate oxide damage and latch-up in downstream load switches rated ≤30V. |
| IoT Edge Node Power Rails | Tablet & Notebook VBus Protection |
Use Scenario: Securing 12–22V power inputs in battery-powered IoT gateways subjected to ESD during field servicing. IC Role / Device Role / Timing Role: Single-component solution replacing multi-diode TVS arrays - simplifies layout and BOM. Use Value: ±30kV ESD rating and 175pF capacitance enable robust protection without compromising power rail stability or EMC. |
Use Scenario: Protecting main VBus lines in ultraportable notebooks where space constraints limit discrete TVS options. IC Role / Device Role / Timing Role: High-density transient suppressor mounted adjacent to USB-C receptacle to minimize trace inductance. Use Value: 1.6×1.6mm DFN-6 footprint allows placement within 2mm of connector - critical for sub-nanosecond ESD response. |
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 code "T22" - direct Semtech factory variant with tape-and-reel packaging. | No functional difference; used interchangeably in production for same USB PD and industrial applications. | Select TDS2211P.C for volume procurement with standard 3,000-unit reels; SC600AIMSTRT is functionally identical but may reflect alternate distribution channel branding. |
| uClamp2411ZA | 24V working voltage, lower 20A IPP rating, higher 30V clamping, smaller 0.6×0.3mm SOD-323 package - optimized for CC/SBU lines, not VBus. | Intended for low-capacitance data-line protection (≤0.3pF), not power rail surge handling. | Not suitable as direct replacement for SC600AIMSTRT - use only for auxiliary signal lines; SC600AIMSTRT remains required for 22V power rail protection. |
Compared with TDS2211P.C, SC600AIMSTRT offers identical protection performance and package; compared with uClamp2411ZA, SC600AIMSTRT provides 2× peak current rating, 3V lower clamping, and power-rail-rated thermal design - making it the sole appropriate choice for 22V VBus EOS suppression.

FAQ
What is the exact package type and dimensions of SC600AIMSTRT?
SC600AIMSTRT uses a 6-pin DFN package measuring 1.6mm × 1.6mm × 0.55mm with no thermal pad. Pin 1 is marked by a laser dot; pins 1–3 are GND, pins 4–6 are IN. All six pins must be soldered to achieve full 40A surge rating and optimal PCB thermal performance.
Does SC600AIMSTRT meet IEC 61000-4-5 Level 4 surge immunity?
Yes, SC600AIMSTRT is rated for 40A peak pulse current with 8/20μs waveform per IEC 61000-4-5, satisfying Level 4 (4kV open-circuit, 2Ω source impedance) requirements for industrial equipment. Its 27.5–28V clamping ensures protected devices remain within safe operating limits during such events.
How does SC600AIMSTRT differ from standard TVS diodes in clamping behavior?
Unlike standard TVS diodes whose clamping voltage rises linearly with current (VC = VBR + IPP × RDYN), SC600AIMSTRT uses an active FET shunt that maintains near-constant 27.5–28V clamping from 24A to 40A and across −40°C to +125°C - eliminating derating uncertainty in thermal or high-current designs.
Can SC600AIMSTRT be used to protect USB-C CC and SBU lines?
No - SC600AIMSTRT is designed for 22V power rail protection (e.g., VBus) and is not suitable for CC/SBU lines. Those require ultra-low-capacitance devices like uClamp2411ZA (≤0.3pF); using SC600AIMSTRT (175pF) would disrupt USB PD communication and signal integrity.
Is SC600AIMSTRT RoHS and halogen-free compliant?
Yes, SC600AIMSTRT is fully RoHS/WEEE compliant and halogen-free, with Pb-free lead finish and UL 94V-0 flammability-rated molding compound. It meets environmental compliance requirements for global industrial, computing, and consumer electronics markets.
