Product details
Overview
SC410MLTRT 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 SC410MLTRT 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 22V bus protection.
Technical Context
The SC410MLTRT 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 across 0–40A (8/20μs) due to decreasing RDS(on) under surge conditions.
It operates over –40°C to +125°C with <600nA reverse leakage at 22V, 175pF junction capacitance at 22V/1MHz, and maintains stable 27.5–28V clamping up to 125°C - eliminating thermal derating concerns common in standard TVS devices.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - matches nominal USB PD VBus and industrial 24V rail systems without derating. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs) - stays below 29V across full temperature range, protecting 30V-tolerant controllers. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 surge immunity for industrial equipment. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds USB IF and IEC 61000-4-2 Class 4 requirements. |
| Dynamic Resistance | 20mΩ - enables low-voltage overshoot during fast transients, critical for sensitive load switches. |
| Junction Capacitance | 175pF at 22V/1MHz - suitable for DC power rails and low-speed control lines, not high-speed data. |
| Operating Temp | –40°C to +125°C - supports extended-temperature industrial and automotive under-hood environments. |
Pinout & Package
SC410MLTRT is housed in a RoHS-compliant, halogen-free DFN-6 package measuring 1.6mm × 1.6mm × 0.55mm with exposed thermal pad (no solder mask defined). All six terminals are electrically active: three parallel input pins and three parallel ground pins - mandatory connection of all pins required for rated 40A surge performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Parallel ground terminals - must all be connected to low-inductance ground plane via multiple vias to sustain 40A surge current. |
| Pins 4, 5, 6 | IN | Parallel input terminals - connect directly to protected line (e.g., USB PD VBus); all three required for full current sharing and thermal distribution. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies ≤0.5V from 24A to 40A (8/20μs), eliminating design margin inflation needed with TVS diodes. |
| FET-based shunt topology | Dissipates surge energy in low-RDS(on) channel instead of PN junction - enables stable performance across –40°C to +125°C. |
| Low dynamic resistance | 20mΩ ensures minimal IR drop during surge, limiting overshoot to <0.8V above clamping threshold at 40A. |
| High EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns, 5kHz & 100kHz) - protects against repetitive switching noise in motor drives and PLCs. |
| Space-optimized packaging | 1.6mm × 1.6mm footprint saves >60% board area vs. SO-8 or SOT-23 TVS solutions rated for equivalent surge energy. |
Applications
| USB Type-C Power Delivery Protection | Industrial Load Switch Input Protection |
|---|---|
|
Use Scenario: Protecting the VBus line of a USB Type-C port supporting up to 20V/5A power delivery in notebooks and docking stations. IC Role / Device Role / Timing Role: Transient diverting suppressor placed between connector and PD controller or load switch input. Use Value: Maintains 27.5–28V clamping across –40°C to +125°C, preventing damage to 30V-rated PD controllers even under worst-case ambient conditions. |
Use Scenario: Safeguarding the input of an industrial-grade load switch (e.g., HS2950P) in remote metering or robotics systems exposed to lightning-induced surges. IC Role / Device Role / Timing Role: Primary EOS protection device placed at PCB edge before load switch VIN pin. Use Value: Limits transient voltage to ≤28V during 40A/8/20μs events, keeping stress below the 30V absolute maximum rating of internal FETs in high-side switches. |
| IoT Device Power Rail Protection | Storage Device 24V Backup Supply Protection |
|
Use Scenario: Securing the main 22V input rail of battery-backed IoT gateways deployed in uncontrolled outdoor environments. IC Role / Device Role / Timing Role: Standalone EOS protector on primary DC input, upstream of DC-DC converters and PMICs. Use Value: Delivers ±30kV ESD robustness and 40A surge handling while adding only 175pF capacitance - no signal integrity impact on power rails. |
Use Scenario: Protecting the 24V auxiliary supply rail in enterprise SSD enclosures or NAS units with hot-swap capability. IC Role / Device Role / Timing Role: Clamping device on backup power input to prevent EOS damage during insertion/removal or grid transients. Use Value: Enables compliance with IEC 61000-4-5 Level 4 (±1kV, 42Ω source) without requiring oversized TVS arrays or complex multi-stage designs. |
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-manufactured variant with tape-and-reel packaging (3,000 pcs/reel). | No functional difference; used interchangeably in production where reel quantity and date-code traceability are required. | Select TDS2211P.C when sourcing from authorized Semtech distributors with full traceability and standard logistics support. |
| SMAJ22A | Standard unidirectional TVS diode; 22V VRWM, 35.5V VC @ 12.3A (8/20μs), 100W PPPK, 5.0×3.5mm SMA package - higher clamping, lower surge rating, larger footprint. | Limited to lower-energy transients; clamping rises with temperature and current - unsuitable for 40A or high-temp industrial use. | Choose SMAJ22A only for cost-sensitive, non-critical 22V lines where 35.5V clamping and <15A surge capability are acceptable. |
Compared with SC410MLTRT, TDS2211P.C offers identical performance with certified traceability, while SMAJ22A provides lower-cost TVS protection at the expense of clamping stability, surge capacity, and thermal robustness - making SC410MLTRT the preferred choice for mission-critical 22V EOS protection.

FAQ
What is the exact package type and dimensions of SC410MLTRT?
SC410MLTRT uses a 6-pin DFN package measuring 1.6mm × 1.6mm × 0.55mm with exposed thermal pad. Pin 1 is marked by a laser dot; pins 1–3 are GND, pins 4–6 are IN. The land pattern requires full copper pour under the package and ≥3 vias per GND pin to ensure 40A surge capability - details are specified in Semtech's DFN-1.6x1.6mm outline drawing.
Does SC410MLTRT require external bias or control signals to operate?
No, SC410MLTRT is fully passive and self-triggering. It contains an integrated precision trigger circuit and surge-rated FET - no external power, enable pin, or configuration is needed. The device activates automatically when transient voltage exceeds ~25V (VBR), turning on the shunt path within nanoseconds to clamp the protected line.
How does SC410MLTRT differ from standard TVS diodes like SMAJ22A in real-world performance?
SC410MLTRT clamps at 27.5–28V across 0–40A and –40°C to +125°C, while SMAJ22A clamps at 35.5V at just 12.3A and degrades further at high temperature. SC410MLTRT's 20mΩ dynamic resistance and FET-based topology deliver tighter voltage control and superior thermal stability - critical for protecting 30V-tolerant PD controllers and load switches.
Can SC410MLTRT be used on high-speed data lines such as USB SuperSpeed or PCIe?
No, SC410MLTRT is not suitable for high-speed data lines. Its 175pF junction capacitance would severely degrade signal integrity on differential pairs operating above 100MHz. It is intended exclusively for DC power rails and low-speed control lines (e.g., VBus, EN, OVP inputs). For USB SS/DP/DM lines, Semtech recommends RClamp3371ZC (<0.25pF).
Is SC410MLTRT compliant with RoHS, REACH, and halogen-free standards?
Yes, SC410MLTRT is Pb-free, halogen-free, and fully compliant with RoHS Directive 2011/65/EU and WEEE Directive 2012/19/EU. The molding compound meets UL 94V-0 flammability rating, and lead finish is 100% matte tin - confirmed in Semtech's official TDS2211P datasheet Rev 2.5, page 2.
