S8X8ESAP

Scrs Overview

The Littelfuse S8X8ESAP is a silicon controlled rectifier (SCR) designed for high-temperature and sensitive gate applications. It features a maximum repetitive peak off-state voltage of 800V and a non-repetitive surge current capability of up to 100A at 50/60Hz under resistive load conditions. The device operates within a junction temperature range of -40°C to +125°C, with a specific rating of +150°C noted in some documentation. Packaged in a TO-92 through-hole case, it supports an average on-state current of 800mA.

Scrs Feature Summary

• Sensitive gate architecture enabling reliable triggering with low gate drive requirements
• Glass-passivated junctions providing enhanced durability for ground fault circuit interrupter and gas ignition environments
• High thermal stability supporting operation in elevated temperature industrial settings

Scrs Applications

• Ground Fault Circuit Interrupter (GFCI) protection circuits
• Gas ignition control systems
• High-temperature power switching applications

Scrs Procurement Notes

Verify the exact suffix against official Littelfuse documentation to confirm package type and electrical ratings. Ensure the selected variant matches the required voltage and current specifications for the target application. Cross-reference datasheets from authorized distributors to confirm active status and availability. Confirm compliance with RoHS and halogen-free requirements if necessary for the end product.

Scrs Selection Notes

Select this component when a sensitive gate SCR is required for compact through-hole designs. Consider the 800V blocking voltage and 800mA on-state current limits for circuit planning. Evaluate the thermal management needs given the high-temperature rating. Ensure the TO-92 package fits the mechanical constraints of the assembly.

Scrs Part Context

This part belongs to the SJx08x or SxX8xSx series of high-temperature SCRs from Littelfuse. These devices are engineered for robust performance in demanding environments. The series emphasizes reliability in safety-critical applications such as GFCIs and ignition controls, utilizing glass-passivation technology to protect the semiconductor junction.

Scrs Replacement Considerations

Consult official Littelfuse substitution guides for verified alternatives. Generic cross-references may not match the sensitive gate characteristics or thermal ratings. Verify pinout compatibility and package dimensions before replacing.
