Overview
The S8X8ESRP is a silicon-controlled rectifier (SCR) manufactured by Littelfuse, designed for high-voltage switching 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 sensitive gate structure requiring a trigger current of 50 uA at a voltage of 800 mV. Packaged in a TO-92 through-hole configuration, it 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 drop of 1.7 V, and a leakage current of 3 uA under rated conditions.
Feature Summary
- Sensitive gate architecture enabling reliable triggering with low control power requirements.
Applications
- High-voltage AC switching circuits
- Phase control applications
- Solid-state relay inputs
Procurement Notes
Verify the specific suffix 'RP' against the manufacturer's official datasheet to confirm packaging details such as reel or cut tape specifications. Ensure the component meets RoHS compliance requirements for the intended assembly process. Cross-reference the Littelfuse part number with authorized distributor catalogs to validate availability and authenticity before procurement.
Selection Notes
Select this SCR for designs requiring moderate current handling with high voltage isolation in a compact through-hole package. The sensitive gate characteristic simplifies drive circuit design compared to standard gates. Verify that the thermal management strategy accommodates the junction temperature limits during continuous operation and surge events.
Part Context
This component belongs to the SxX8xSx series of thyristors from Littelfuse. The series is characterized by robust construction suitable for industrial and consumer electronics. The TO-92 package provides a cost-effective solution for low-to-medium power applications where board space is constrained but through-hole mounting is preferred.
Replacement Considerations
Consult Littelfuse documentation for direct pin-compatible alternatives within the same voltage and current ratings. Generic SCRs may differ in gate sensitivity or holding current, potentially affecting circuit stability. Verify thermal and electrical parameters match the original design constraints before substitution.
