Product details
Overview
SC600BIMLTRT from Semtech is a Transient Diverting Suppressor (TDS) designed for high-energy EOS protection of 22V-rated power or I/O lines. It delivers ±30kV IEC 61000-4-2 ESD immunity, 40A peak pulse current (8/20μs), and a stable 27.5–28V clamping voltage across temperature and current range. It is used in USB Type-C PD input protection to safeguard controllers from voltage overshoot during lightning surges or connector hot-plug events.
For engineers reviewing the SC600BIMLTRT datasheet, pinout, applications, or equivalent options, this page provides verified electrical parameters, DFN-6 package layout guidance, real-world clamping behavior vs. temperature, and validated alternatives for industrial and portable power interface designs.
Technical Context
The SC600BIMLTRT uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit that senses overvoltage transients. Unlike conventional TVS diodes, its clamping voltage remains nearly constant-27.5–28V at 24A and 40A-due to the FET's ultra-low dynamic resistance (20 mΩ) and decreasing RDS(on) under surge conditions.
It operates from −40°C to +125°C with reverse stand-off voltage of 22V, breakdown voltage of 25–27.9V, and junction capacitance of 175 pF at 22V/1MHz. Its 6-pin DFN (1.6 × 1.6 × 0.55 mm) integrates three parallel IN terminals (pins 4–6) and three GND terminals (pins 1–3) to maximize surge current handling and minimize parasitic inductance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22 V - matches nominal USB PD bus voltage and protects against sustained overvoltage up to rated limit. |
| Clamping Voltage | 27.5–28 V at 40A (8/20μs) - stays flat across full surge range, enabling reliable margin below 30V controller damage thresholds. |
| Peak Pulse Current | 40 A (8/20μs) - meets IEC 61000-4-5 Level 4 industrial surge immunity requirements for 22V systems. |
| ESD Withstand | ±30 kV contact & air (IEC 61000-4-2) - exceeds USB IF and industrial ESD test requirements without derating. |
| Dynamic Resistance | 20 mΩ - ensures minimal voltage rise under surge, critical for low-voltage tolerance in load switch inputs. |
| Junction Capacitance | 175 pF at 22V/1MHz - compatible with DC-biased power rails; not intended for high-speed data line protection. |
| Operating Temperature | −40°C to +125°C - supports operation in automotive cabin, industrial enclosures, and ruggedized IoT edge devices. |
Pinout & Package
SC600BIMLTRT is housed in a Pb-free, RoHS-compliant 6-lead DFN package measuring 1.6 mm × 1.6 mm × 0.55 mm (UL 94V-0 molding compound). All six terminals must be connected-three IN pins in parallel and three GND pins in parallel-to achieve full 40A surge rating and minimize ground loop inductance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground return path; all three must be soldered to a low-inductance ground plane via multiple vias. |
| Pins 4, 5, 6 | IN | Parallel-connected input terminals for protected bus; single trace from connector required for optimal ESD coupling control. |
Key Features
| Feature | Design Value |
|---|---|
| FET-based transient shunt | Replaces traditional TVS with active clamping: enables flat VC vs. IPP curve and eliminates thermal runaway risk at high ambient temperatures. |
| Stable clamping over temperature | VC remains 27.5–28V from −40°C to +125°C - eliminates need for derating or worst-case thermal margining in industrial designs. |
| Low dynamic resistance | 20 mΩ measured between 1A–40A - reduces voltage overshoot during fast-rising surges (e.g., lightning-induced ring waves). |
| High-energy surge rating | 1120 W peak pulse power (8/20μs) - supports repeated surge events in metering, robotics, and remote sensing applications. |
| DFN-6 footprint | 1.6 × 1.6 mm area - saves >50% board space versus SO-8 or SOT-23 TVS solutions while maintaining robust thermal and electrical performance. |
Applications
| USB Type-C Power Delivery Input Protection | Industrial Load Switch Input Protection |
|---|---|
|
Use Scenario: Protecting the VBUS line of a USB Type-C port supporting up to 20V/5A PD negotiation against ESD, lightning surges, and hot-plug transients. IC Role / Device Role / Timing Role: Primary front-end EOS suppressor placed directly at the connector, clamping transients before they reach the PD controller or load switch IC. Use Value: Maintains 27.5–28V clamping across 40A and −40°C to +125°C - prevents false shutdown or latch-up of downstream 30V-rated PD controllers. |
Use Scenario: Safeguarding the input of high-side load switches (e.g., HS2950P) in smart meters, PLC I/O modules, and robotic power distribution units. IC Role / Device Role / Timing Role: Surge diverter placed upstream of the load switch FET to prevent gate oxide damage and drain-source avalanche failure during line transients. Use Value: Limits voltage across load switch input to ≤28V during 40A surges - avoids exceeding the 30V absolute maximum rating of common industrial load switches. |
| IoT Edge Device Power Rail Protection | Storage Device 22V Backup Supply Protection |
|
Use Scenario: Securing 22V auxiliary power inputs on battery-backed wireless gateways, environmental sensors, and cellular modems deployed outdoors or in ungrounded environments. IC Role / Device Role / Timing Role: Standalone transient suppressor on DC input rail, operating without bias or control signals - fully passive and always-active protection. Use Value: Delivers ±30kV ESD immunity and 40A surge capability in a 1.6 mm² footprint - enables compact, sealed enclosure designs without external spark gaps or MOVs. |
Use Scenario: Protecting 22V backup battery or supercapacitor charging circuits in enterprise SSDs, NAS enclosures, and RAID controllers during AC mains disturbances. IC Role / Device Role / Timing Role: Bidirectional clamping device placed between backup supply and system rail to absorb reverse-polarity and surge energy during failover transitions. Use Value: Low 175 pF capacitance avoids signal integrity issues on DC rails; stable clamping prevents backup supply overvoltage from corrupting NAND flash or DRAM retention. |
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 | Same die, identical electrical specs, identical DFN-6 package; differs only in tape-and-reel packaging (3,000 pcs/reel vs. SC600BIMLTRT's unspecified quantity). | No functional difference; both qualified for USB PD and industrial load switch protection per Semtech documentation. | Select TDS2211P.C when standard reel size and traceability per Semtech's ordering code are required. |
| uClamp2411ZA.TCT | Zener-based TVS with 24V working voltage, 33V clamping at 1A, higher dynamic resistance (>1 Ω), and ±30kV ESD rating - lacks flat-clamp behavior and temperature stability. | Suitable only for lower-energy CC/SBU line protection in USB-C; cannot handle 40A surges or replace SC600BIMLTRT on VBUS or load switch inputs. | Choose uClamp2411ZA.TCT only for secondary signal-line protection where clamping voltage margin allows >30V overshoot. |
Compared with TDS2211P.C (identical function and form) and uClamp2411ZA.TCT (lower surge rating, voltage-sensitive clamping), SC600BIMLTRT offers guaranteed 40A/28V flat-clamp performance in production-grade packaging - making it the preferred choice for primary 22V rail protection where reliability under thermal stress and repeated surges is critical.

FAQ
What is the clamping voltage of SC600BIMLTRT at 40A surge current?
The SC600BIMLTRT clamps at 27.5–28 V under 40A peak pulse current (8/20μs waveform, 2Ω source impedance), with minimal variation across temperature (−40°C to +125°C). This flat clamping behavior is enabled by its FET-based architecture and is confirmed in the official Semtech datasheet Rev 2.5, page 2.
Is SC600BIMLTRT pin-compatible with other Semtech TDS devices?
SC600BIMLTRT shares the same 6-pin DFN (1.6 × 1.6 mm) package and pin configuration (pins 1–3 = GND, pins 4–6 = IN) as TDS2211P.C and TDS2411P. However, SC600BIMLTRT is specified for 22V operation; substituting higher-voltage variants requires verifying breakdown and clamping alignment with system voltage margins.
Can SC600BIMLTRT be used on high-speed data lines like USB SuperSpeed?
No. SC600BIMLTRT has 175 pF junction capacitance at 22V, which would severely degrade signal integrity on USB 3.x or PCIe lanes. It is intended exclusively for DC-biased power or low-frequency I/O lines. For SuperSpeed lines, Semtech recommends RClamp3371ZC (<0.25 pF) instead of SC600BIMLTRT.
Does SC600BIMLTRT require a thermal pad or heatsink?
No. The SC600BIMLTRT dissipates surge energy primarily through conduction into the PCB ground plane-not junction heating-so no thermal pad is needed. Per Semtech's layout guidelines (datasheet page 6), low-inductance grounding via multiple vias is sufficient for full 40A performance.
What is the maximum operating temperature for SC600BIMLTRT?
The SC600BIMLTRT is rated for continuous operation from −40°C to +125°C ambient temperature. Its clamping voltage remains stable across this full range, unlike conventional TVS diodes whose VC increases with temperature - a key advantage confirmed in the TDS2211P datasheet Figure 3.
