Overview
The Littelfuse S4006DTP is a silicon-controlled rectifier (SCR) designed for power control applications. It features a 400 V repetitive peak off-state voltage and an RMS on-state current rating of 6 A. The device utilizes a sensing gate structure with a maximum DC gate trigger current of 200 µA, enabling low-power triggering. It is housed in a TO-252AA surface-mount package, providing a compact solution for thermal management. The component operates within a junction temperature range of -40 °C to +125 °C and includes a critical rate of rise of off-state voltage specification of 8 V/µs.
Feature Summary
- Sensing gate architecture for efficient low-current triggering
- Surface-mount TO-252AA package for automated assembly
- High thermal stability suitable for industrial environments
Applications
- AC motor speed control circuits
- Solid-state relay inputs
- General purpose power switching
Procurement Notes
Verify the specific suffix against manufacturer documentation to confirm exact binning or testing variations. Ensure the ordering quantity aligns with standard reel sizes if applicable. Confirm RoHS compliance status through the official datasheet before integration into regulated assemblies.
Selection Notes
Select this component when a 6 A SCR with a sensitive gate drive requirement is necessary. The TO-252AA package facilitates PCB mounting where space is constrained. Verify that the 400 V voltage rating meets the peak circuit demands and that the 8 V/µs dv/dt rating is sufficient for the application's noise environment.
Part Context
This part belongs to the Littelfuse S4006 series of general-purpose SCRs. The series offers various voltage ratings and packaging options to suit different power levels. The S4006DTP specifically targets applications requiring moderate current handling with precise gate sensitivity in a surface-mount form factor.
Replacement Considerations
Direct replacements include the S4006DS2RP and S4006DS2TP from the same manufacturer family. These alternatives share similar electrical characteristics but may differ in specific gate sensitivities or packaging tolerances. Verify pinout compatibility before substitution.
