Product details
Overview
SC600DIMLTRT 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 ultra-low 20mΩ dynamic resistance. It protects USB PD, USB Type-C VBUS, and load switch inputs in industrial and portable electronics.
For engineers reviewing the SC600DIMLTRT datasheet, pinout, applications, or equivalent options, key selection criteria include clamping stability across temperature (−40°C to +125°C), DFN 1.6×1.6mm 6-lead package footprint, low 175pF junction capacitance, and shunt-FET-based architecture enabling constant-voltage clamping unlike conventional TVS diodes.
Technical Context
The SC600DIMLTRT uses a surge-rated MOSFET as its primary protection element, activated by a precision trigger circuit that senses overvoltage events and turns on the FET to shunt transients to ground. Its clamping voltage remains nearly constant (27.5–28V) from 24A to 40A due to decreasing RDS(on) under surge conditions.
This architecture delivers superior thermal stability versus standard TVS diodes: clamping voltage variation is <±0.5V across −40°C to +125°C, and peak pulse current capability remains stable up to 125°C - unlike TVS devices whose IPP degrades with rising temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - supports USB PD 20V nominal bus with 22V maximum operating margin. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs + 1.2/50μs combo wave) - stays below 29V across full rated current and temperature range. |
| 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 Type-C ESD robustness requirements. |
| Dynamic Resistance | 20mΩ - enables low-voltage drop during surge conduction, minimizing stress on downstream FETs. |
| Junction Capacitance | 175pF at 22V, 1MHz - compatible with high-speed power rail monitoring without signal distortion. |
| Operating Temperature | −40°C to +125°C - qualified for automotive under-hood and industrial control environments. |
Pinout & Package
SC600DIMLTRT is housed in a RoHS-compliant, halogen-free DFN 1.6mm × 1.6mm × 0.55mm 6-lead package with exposed thermal pad (no solder mask defined). All pins must be connected - three GND pins (1–3) and three IN pins (4–6) - to achieve full 40A surge rating and minimize parasitic inductance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Low-inductance ground return path; all three must be vias-connected to internal ground plane for full 40A capability. |
| 4, 5, 6 | IN | Protected line input (e.g., USB PD VBUS); parallel connection ensures uniform current sharing and thermal distribution. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies ≤0.5V from 24A to 40A and −40°C to +125°C - eliminates derating calculations required for TVS diodes. |
| Shunt-FET protection core | Replaces avalanche junction with low-RDS(on) MOSFET, reducing energy dissipation in silicon and improving reliability under repeated surges. |
| Low dynamic resistance | 20mΩ enables <0.8V IR drop at 40A - prevents upstream overvoltage during fast-rising transients (e.g., lightning-induced surges). |
| High EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns, 100kHz/5kHz) - protects against burst noise in motor drives and PLC I/O modules. |
Applications
| USB Type-C Power Delivery Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting 20V USB PD VBUS lines against ESD, lightning surges, and hot-plug transients in notebooks and docking stations. IC Role / Device Role / Timing Role: Primary shunt protector placed adjacent to Type-C connector, clamping transients before they reach PD controller or e-fuse. Use Value: Maintains 27.5–28V clamping across temperature - avoids overvoltage damage to 30V-rated PD controllers even at 125°C ambient. |
Use Scenario: Safeguarding input terminals of high-side load switches (e.g., HS2950P) in remote meters and robotics. IC Role / Device Role / Timing Role: Front-end transient diverter that limits voltage seen by the load switch's internal FET gate oxide. Use Value: Prevents gate-oxide rupture by holding clamped voltage <29V - well below typical 30–35V FET breakdown thresholds. |
| IoT Edge Node Power Bus Protection | Storage Device 22V Rail Protection |
Use Scenario: Securing 22V auxiliary rails in battery-powered IoT gateways exposed to field ESD and induced surges. IC Role / Device Role / Timing Role: Single-device solution replacing multi-stage TVS+MOV networks, reducing BOM count and PCB area. Use Value: 1.6×1.6mm DFN footprint saves >60% board space vs. discrete TVS+capacitor solutions while delivering higher surge rating. |
Use Scenario: Protecting 22V power inputs of NVMe SSD enclosures and enterprise storage backplanes. IC Role / Device Role / Timing Role: High-energy surge limiter compliant with IEC 61000-4-5 Level 4 (±1kV, RS=42Ω) for data center infrastructure. Use Value: 1120W peak pulse power rating ensures survival of multiple 1kV surges without parameter drift or degradation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDS2211P.C | Identical electrical specs, same DFN 1.6×1.6mm package, identical pinout and marking (T22XX), but differs only in tape-and-reel packaging (3,000 pcs/reel vs. SC600DIMLTRT's unspecified quantity). | Same use cases: USB PD, load switch, industrial 22V rail protection. | Select TDS2211P.C when standard Semtech reel packaging is required; SC600DIMLTRT may reflect alternate logistics configuration. |
| SMAJ22A | Standard unidirectional TVS diode; 22V standoff, 35.5V max clamping at 15.5A (8/20μs), 1.5Ω dynamic resistance - clamping rises linearly with current and temperature. | Lower-cost option for non-critical 22V rails where ±30kV ESD and 40A surge are not required. | Choose SMAJ22A only if clamping voltage drift ≤3V over temperature and ≤10A surge rating are acceptable; not suitable for USB PD or high-reliability load switches. |
Compared with TDS2211P.C, SC600DIMLTRT offers identical performance and form factor, differing only in packaging logistics; versus SMAJ22A, SC600DIMLTRT delivers 2.6× higher surge current, ±30kV ESD, and thermally stable clamping - making it essential for USB PD and industrial-grade 22V protection where reliability is non-negotiable.

FAQ
What is the exact package type and dimensions of SC600DIMLTRT?
SC600DIMLTRT uses a DFN (Dual Flat No-lead) package measuring 1.6mm × 1.6mm × 0.55mm with 6 leads. Pin 1 is marked by a laser dot; pins 1–3 are GND, and pins 4–6 are IN. The package is Pb-free, halogen-free, and RoHS/WEEE compliant with UL 94V-0 molding compound.
Does SC600DIMLTRT meet IEC 61000-4-5 surge immunity standards?
Yes, SC600DIMLTRT is rated for 40A peak pulse current (8/20μs waveform) and withstands ±1kV combination wave surges (1.2/50μs voltage, 8/20μs current, RS = 42Ω), satisfying IEC 61000-4-5 Level 4 for industrial equipment. Its clamping voltage remains ≤28V under these conditions.
How does SC600DIMLTRT differ from standard TVS diodes like SMAJ22A?
Unlike SMAJ22A - a junction-based TVS with rising clamping voltage (VC = VBR + IPP × RDYN) - SC600DIMLTRT uses a triggered shunt FET delivering near-constant 27.5–28V clamping from 24A to 40A and −40°C to +125°C, with 20mΩ dynamic resistance versus ~1.5Ω in SMAJ22A.
Can SC600DIMLTRT protect USB Type-C CC and SBU lines?
No - SC600DIMLTRT is optimized for 22V power-line protection (e.g., VBUS) and is not suitable for low-voltage, high-speed CC/SBU lines due to its 175pF capacitance. For those lines, Semtech recommends uClamp2411ZA (24V, <10pF) as specified in the TDS2211P application note.
What is the maximum junction temperature and thermal derating behavior of SC600DIMLTRT?
SC600DIMLTRT has a junction temperature range of −55°C to +150°C and operates continuously from −40°C to +125°C. Its clamping voltage and peak pulse current remain stable across this range - no thermal derating is required for IPP or VC, unlike conventional TVS diodes whose ratings degrade above 85°C.
