SK006DTP

Overview

The SK006DTP is a Silicon Controlled Rectifier (SCR) manufactured by Littelfuse Inc., designed for surface-mount applications. It features a TO-252 (DPAK) package and offers a standard recovery characteristic. The device is rated for a repetitive peak off-state voltage of 1 kV and an on-state current of 6 A. Non-repetitive on-state current capability reaches 100 A. This component serves as a robust power control solution within compact electronic designs requiring reliable thyristor switching.

Feature Summary

• Surface-mount construction in a TO-252 (DPAK) package for automated assembly
• Standard recovery characteristics suitable for general power control applications
• High non-repetitive surge current handling capability

Applications

• AC/DC power control circuits
• Solid-state relay inputs
• Motor speed control systems

Procurement Notes

Verify the specific ordering suffix to ensure the correct package variant and tape-and-reel configuration match your manufacturing requirements. Confirm that the thermal resistance parameters align with your PCB layout and heat dissipation strategy. Cross-reference the datasheet revision date to ensure compliance with current electrical specifications and mechanical dimensions before finalizing the bill of materials.

Selection Notes

Select this component when a surface-mount SCR is required for high-voltage isolation and moderate current switching. The TO-252 package provides a balance between thermal performance and board space efficiency. Ensure the circuit design accounts for the 1 kV blocking voltage and 6 A continuous current limits. Consider the non-repetitive surge rating for transient protection scenarios during startup or fault conditions.

Part Context

This part belongs to the Littelfuse thyristor family, specifically engineered for power electronics. It complements other discrete semiconductors used in industrial and consumer power supplies. The DPAK form factor allows integration into dense assemblies where traditional through-hole components would exceed spatial constraints. It supports modern manufacturing techniques while maintaining high reliability standards.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. When evaluating alternatives, verify that any replacement matches the 1 kV voltage rating, 6 A current capacity, and TO-252 package dimensions. Ensure the new component maintains equivalent gate trigger characteristics and thermal performance to avoid redesigning the surrounding circuitry.
