S6008L

Overview

The Littelfuse S6008L is a Silicon Controlled Rectifier (SCR) from the Teccor line, designed as a half-wave, unidirectional, gate-controlled rectifier. It features an electrically isolated package with a glass-passivated junction for parameter stability and long-term reliability. The device supports ratings from 1 A to 70 A and voltages from 200 V to 1000 V. Specific parameters include a maximum RMS on-state current of 8 A, a rated repetitive off-state voltage of 600 V, and a non-repetitive peak on-state current of 100 A. It operates within a temperature range of -40°C to +110°C and utilizes a TO-220AB flange mount package.

Feature Summary

• Electrically-isolated package construction allowing low-cost assembly techniques
• Glass-passivated chip providing a rugged barrier against junction contamination
• High surge capability supporting demanding switching applications

Applications

• General purpose power control circuits
• Industrial electronic controls
• Solid-state switching systems

Procurement Notes

Verify the specific suffix designation when ordering, as Littelfuse product lines often utilize suffixes to denote variations in packaging or testing criteria. Confirm RoHS compliance status directly with the manufacturer or authorized distributor documentation, as regulatory status can vary by production batch and region. Ensure the selected variant matches the required isolation and thermal specifications for the intended application environment.

Selection Notes

Select this component based on its 600 V blocking voltage and 8 A RMS current rating. The TO-220AB flange mount package requires appropriate heatsinking for thermal management. Verify that the gate trigger requirements align with the driving circuit capabilities. Consider the glass-passivated junction technology if environmental protection against contamination is a priority for the design.

Part Context

The S6008L belongs to the Littelfuse Teccor series of thyristors, which complement the company's sensitive SCR offerings. This series provides devices with varying ampere and voltage ratings, utilizing standard industrial packages. The S6008L specifically addresses applications requiring moderate current handling with high voltage isolation in a robust, cost-effective form factor.

Replacement Considerations

Direct replacements must match the 600 V / 8 A specification and TO-220AB isolation package. Cross-reference with other manufacturers' SCRs offering similar I(T)RMS and V(DRM) ratings. Verify pinout compatibility and thermal resistance characteristics before substituting to ensure circuit performance remains within safe operating limits.
