Overview
The Littelfuse S8X8ES1RP is a silicon-controlled rectifier (SCR) from the SxX8xSx series, housed in a TO-92 through-hole package. It features an 800 V rated repetitive off-state voltage and an RMS on-state current of 800 mA. The device requires a gate trigger current of 50 uA at 800 mV to activate. It operates within a temperature range of -40 C to +125 C and exhibits a maximum holding current of 5 mA. Non-repetitive peak on-state current is rated at 10 A, with a forward voltage drop of 1.7 V.
Feature Summary
- High-voltage capability for sensitive control applications
- Low gate trigger current for efficient drive circuits
- Robust thermal performance across wide operating ranges
Applications
- AC power control circuits
- Lighting dimmer systems
- Motor speed control interfaces
Procurement Notes
Verify the specific suffix RP against official Littelfuse documentation to confirm packaging configuration. Ensure the component matches the required TO-92 lead form factor. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing supply chain agreements.
Selection Notes
Select this SCR when an 800 V blocking voltage and 800 mA continuous current are required in a compact three-terminal package. The low gate sensitivity makes it suitable for microcontroller-driven applications. Verify that the thermal management design supports the specified junction temperature limits under expected load conditions.
Part Context
This component belongs to the SxX8xSx family of SCRs designed for general-purpose switching. It shares core electrical characteristics with variants like the S8X8ES1, differing primarily in packaging or reel specifications. The series is engineered for reliable operation in consumer and industrial electronics requiring robust thyristor switching.
Replacement Considerations
Direct substitutes include other S8X8ES1 variants with compatible pinouts. Verify equivalent voltage and current ratings when considering cross-brand alternatives. Ensure replacement devices meet the same thermal and mechanical constraints for seamless integration.
