Overview
The S8X8ES2AP is a silicon-controlled rectifier (SCR) manufactured by Littelfuse, designed for power control applications. It features an 800 V rated repetitive off-state voltage and supports an RMS on-state current of 800 mA. The device operates within a temperature range of -40°C to +125°C and utilizes a TO-92 through-hole package. Key electrical characteristics include a gate trigger voltage of 800 mV, a gate trigger current of 50 µA, and a holding current maximum of 5 mA. The forward voltage drop is specified at 1.7 V, with a non-repetitive peak on-state current capability of 10 A.
Feature Summary
- High-voltage blocking capability suitable for demanding power circuits
- Low gate sensitivity enabling efficient triggering with minimal drive current
- Robust thermal performance allowing operation in high-temperature environments
Applications
- AC power switching circuits
- Lighting control systems
- Motor speed regulation
Procurement Notes
Verify the specific suffix 'AP' against official Littelfuse documentation to confirm exact binning or testing variations compared to standard variants. Ensure the ordering information matches the required package style and compliance standards such as RoHS before finalizing procurement.
Selection Notes
Select this component when an SCR with 800 V blocking voltage and approximately 0.8 A continuous current handling is required. Consider the TO-92 package constraints for board space and the low gate trigger current for driver compatibility. Verify that the 10 A surge rating meets the application's transient requirements.
Part Context
This part belongs to the SxX8xSx series of SCRs from Littelfuse, which are characterized by their compact form factor and reliable performance in general-purpose power control tasks. The series offers various voltage and current ratings to suit different circuit designs while maintaining consistent electrical characteristics across the family.
Replacement Considerations
Consult Littelfuse datasheets for direct pin-compatible alternatives within the same series. Verify that any substitute SCR matches the 800 V voltage rating, 800 mA current capacity, and TO-92 package dimensions to ensure seamless integration without circuit redesign.
