Overview
The Littelfuse S4006NRP is a silicon-controlled rectifier (SCR) from the Teccor Sxx40x series, designed for surface-mount applications in the SMTO-263-2 package. It features a rated repetitive off-state voltage of 400 V and an on-state RMS current of 6 A. The device supports a non-repetitive peak on-state current of 520 A with a maximum holding current of 60 mA. Electrical characteristics include a forward voltage of 1.8 V, a gate trigger voltage of 1.5 V, and a gate trigger current of 40 mA. Leakage current at rated voltage is limited to 10 uA. The component operates within a temperature range of -40 C to +125 C.
Feature Summary
- Surface-mount construction in a compact SMTO-263-2 package for automated PCB assembly
- High surge current capability suitable for demanding power control circuits
- Sensitive gate triggering for simplified drive circuit design
Applications
- General purpose AC power switching
- Lighting control systems
- Solid state relays
Procurement Notes
Verify the specific suffix RP against official Littelfuse documentation to confirm tape-and-reel packaging requirements. Ensure the ordering part number matches the exact electrical specifications required by the design. Cross-reference the manufacturer datasheet for any recent product change notices or environmental compliance updates before finalizing procurement.
Selection Notes
Select this SCR when a 400 V blocking voltage and 6 A continuous current rating are required in a surface-mount form factor. The sensitive gate characteristic simplifies the driver interface compared to standard gate devices. Verify that the thermal management solution can handle the junction temperature limits during operation.
Part Context
This component belongs to the Littelfuse Teccor Sxx40x series of thyristors. The series provides various current ratings within the same voltage class, allowing designers to scale power handling capabilities while maintaining consistent package dimensions and mounting footprints across different product variants.
Replacement Considerations
Direct replacements must match the 400 V rating, 6 A current capacity, and SMTO-263-2 package. Verify equivalent gate trigger characteristics to ensure compatibility with existing drive circuits without redesign.
