Overview
The Littelfuse S4006LS2TP is a silicon-controlled rectifier (SCR) designed for through-hole mounting in the TO-220 package with an isolated tab. It features a rated repetitive off-state voltage of 400 V and an RMS on-state current of 6 A. The device exhibits a maximum gate trigger current of 200 µA and a gate trigger voltage of 800 mV, classifying it as a sensitive gate SCR. Key electrical parameters include a maximum holding current of 6 mA, a forward voltage drop of 1.6 V, and a non-repetitive peak on-state current of 100 A. It operates within a temperature range of -40°C to +110°C.
Feature Summary
- Sensitive gate architecture enabling reliable triggering with low gate current requirements
- Electrically isolated tab construction for simplified heat sinking and circuit isolation
- Robust thermal performance supporting operation across extended industrial temperature ranges
Applications
- General purpose power control circuits
- AC motor speed regulation systems
- Lighting dimmer applications
Procurement Notes
Verify the specific suffix 'TP' against the manufacturer's official datasheet to confirm packaging details and compliance status. Ensure the ordered component matches the required TO-220 isolated tab configuration. Cross-reference the part number with Littelfuse documentation to validate all electrical ratings before integration into final designs.
Selection Notes
Select this component when a 6 A RMS current rating and 400 V blocking voltage are required in a standard TO-220 footprint. The sensitive gate characteristic makes it suitable for applications where minimal drive power is available. Verify that the isolated tab requirement aligns with the thermal management strategy and insulation needs of the target enclosure design.
Part Context
This part belongs to the Littelfuse Sxx06xSx series of thyristors. It serves as a direct replacement for the discontinued S4006LS2, maintaining identical electrical specifications while offering updated packaging or manufacturing processes. The series provides standardized solutions for medium-power AC switching tasks.
Replacement Considerations
The S4006LS2 is documented as a parameter-equivalent alternative. Verify pinout compatibility and thermal resistance values when substituting between these two specific part numbers to ensure mechanical fit.
