Overview
The Littelfuse S4006RTP is a silicon-controlled rectifier (SCR) designed for high-reliability power control applications. It features a 400 V repetitive peak off-state voltage and a 6 A RMS on-state current rating, housed in an isolated TO-220AB package with a solder tab for efficient thermal management. The device operates within a junction temperature range of -40°C to 110°C and complies with RoHS3 standards. Key electrical characteristics include a maximum gate trigger voltage of 800 mV, a maximum gate trigger current of 200 µA, and a maximum on-state voltage of 1.6 V at rated current.
Feature Summary
- Isolated mounting tab design enables direct heat sinking without additional insulators
- Sensitive gate structure allows reliable triggering with low input power signals
- High surge current capability supports robust performance under transient load conditions
Applications
- Industrial motor speed control systems
- Solid-state relay output stages
- AC power regulation circuits
Procurement Notes
Verify the specific suffix 'RTP' against official Littelfuse documentation to confirm tape-and-reel packaging specifications. Confirm that the component meets required environmental certifications such as RoHS3 before finalizing procurement orders.
Selection Notes
Select this component when an isolated TO-220 package is required for thermal dissipation in medium-power AC switching applications. Ensure the 400 V voltage rating exceeds the peak line voltage and that the sensitive gate characteristics match the available drive circuit capabilities.
Part Context
This SCR belongs to the Littelfuse standard thyristor family, which provides robust solutions for general-purpose power control. The S4006RTP variant specifically addresses needs for isolated mounting configurations in industrial environments where thermal efficiency and electrical isolation are critical design constraints.
Replacement Considerations
Consult Littelfuse datasheets for parameter-equivalent alternatives. Verify pinout compatibility and thermal resistance values when substituting with other TO-220 isolated SCRs from different manufacturers.
