Overview
The S8X5ECSRP is a silicon-controlled rectifier (SCR) from the Littelfuse EV Series, designed for sensitive gate triggering applications. It features an 800 V rated repetitive off-state voltage and supports an RMS on-state current of 800 mA. The device utilizes a TO-92 through-hole package and operates within a temperature range of -40°C to +125°C. Key electrical characteristics include a maximum holding current of 5 mA, a forward voltage of 1.7 V, and a gate trigger current of 50 µA. This component provides reliable switching performance for various electronic circuits requiring robust overcurrent protection and control.
Feature Summary
- Sensitive gate structure enabling reliable triggering with low gate current requirements
- High thermal stability supporting operation in demanding industrial environments
- Robust construction suitable for protecting sensitive semiconductor devices
Applications
- Overcurrent protection for sensitive electronic circuits
- Industrial control systems requiring reliable SCR switching
- Power supply protection modules
Procurement Notes
Verify the specific suffix RP against official Littelfuse documentation to confirm packaging configuration, as suffixes often denote reel or cut tape formats rather than functional changes. Ensure the procurement channel sources directly from authorized distributors to guarantee authenticity and traceability of the EV Series component.
Selection Notes
Select this component when a sensitive gate SCR is required for circuits operating up to 800 V with moderate current handling needs. Consider the TO-92 package constraints for board space and the 50 µA gate sensitivity for driver compatibility. Evaluate thermal management requirements given the 125°C maximum junction temperature limit.
Part Context
The S8X5ECSRP belongs to the EV Series of 0.8 Amp Sensitive SCRs manufactured by Littelfuse. This series is engineered for applications requiring precise triggering characteristics and robust protection capabilities. The part represents a standard offering in Littelfuse's thyristor portfolio, focusing on reliability in industrial and commercial power electronics.
Replacement Considerations
Consult Littelfuse datasheets for direct cross-references within the S8X5 family. Verify pinout compatibility and electrical ratings before substituting with other manufacturers' SCRs to ensure circuit integrity.
