Overview
The Littelfuse S6040NRP is a Silicon Controlled Rectifier (SCR) from the Teccor series, designed for high-power switching applications. It features a rated repetitive off-state voltage of 600 V and an RMS on-state current capacity of 40 A. The device operates within a temperature range of -40 °C to +125 °C and utilizes a TO-263AB (D2PAK-3) surface-mount package with an isolated case connection. Key electrical parameters include a maximum gate trigger current of 40 mA, a forward voltage drop of 1.8 V, and a holding current maximum of 60 mA. It complies with RoHS standards.
Feature Summary
- High current handling capability suitable for demanding power control circuits
- Surface-mount construction for automated PCB assembly
- Isolated case design for simplified thermal management and mounting
Applications
- AC motor speed control systems
- Solid-state relays
- Lighting dimmer circuits
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct packaging and compliance status. Confirm that the TO-263AB footprint matches the target PCB layout. Check for any recent product change notices regarding material composition or pin configuration before finalizing procurement.
Selection Notes
Select this component when a 600 V blocking voltage and 40 A continuous current are required in a compact surface-mount form factor. Ensure the application circuit provides sufficient gate drive current exceeding 40 mA. Verify that the thermal resistance characteristics of the D2PAK package meet the system's heat dissipation requirements under expected load conditions.
Part Context
This SCR belongs to the Littelfuse Teccor Sxx40x family, which standardizes pinouts and mechanical dimensions across various voltage ratings. This consistency allows designers to swap between different voltage variants within the same series without redesigning the PCB footprint, facilitating supply chain flexibility and inventory management.
Replacement Considerations
Direct replacements must match the 600 V rating, 40 A current capacity, and TO-263AB package. Verify equivalent gate trigger specifications. Cross-reference with other manufacturers offering compatible thyristors in the D2PAK-3 outline.
