Procurement Notes
This product is officially marked as obsolete and is no longer manufactured by Littelfuse Inc. Procurement should focus on verified substitute part numbers or alternative package types provided by the manufacturer. Availability is limited to existing stock or secondary market sources, which may carry risks regarding authenticity and shelf life. Verify replacement compatibility before acquisition.
Selection Notes
Select this component only if legacy design compatibility is required. The sensitive gate characteristic allows for lower power gate drive circuits compared to standard SCRs. Ensure the application voltage does not exceed 400 V and current requirements remain within the 10 A limit. Consider modern replacements due to the obsolete status of this specific part number.
Part Context
The S4010VS3 belongs to the Sxx10x series of low-power SCRs from Littelfuse. This series offers voltage capabilities up to 1200 V across different variants. The S4010VS3 specifically addresses the 400 V segment with a 10 A current rating, serving as a compact solution for power control tasks where space and gate sensitivity are critical design factors.
Replacement Considerations
View substitutes or alternative package types via Littelfuse official channels. Cross-reference with other Sxx10x series parts for similar voltage and current ratings.
