Overview
The Littelfuse S8X8ES2RP is a Silicon Controlled Rectifier (SCR) from the Sen series, designed for through-hole mounting in TO-92 packages. It features an 800 V rated repetitive off-state voltage and supports an RMS on-state current of 800 mA. The device requires a gate trigger current of 50 uA at a voltage of 800 mV to activate. 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. It operates within a temperature range of -40 C to +125 C and can withstand non-repetitive peak currents up to 10 A.
Feature Summary
- Low gate sensitivity requiring minimal trigger current for reliable activation
- High voltage blocking capability suitable for demanding power control applications
- Robust thermal performance with extended operating temperature range
Applications
- General purpose AC/DC power control circuits
- Lighting dimmer and motor speed control systems
- Industrial switching and relay replacement applications
Procurement Notes
Verify component authenticity by cross-referencing the manufacturer part number with official Littelfuse documentation. Ensure the specific package type matches design requirements. Confirm compliance with relevant environmental standards such as RoHS before finalizing procurement decisions for production integration.
Selection Notes
Select this SCR based on its 800 V voltage rating and 800 mA current capacity relative to circuit load requirements. Consider the low gate trigger current for driver compatibility. Evaluate the TO-92 package constraints against available PCB space and thermal dissipation needs for the intended application environment.
Part Context
This component belongs to the Littelfuse Sen series of SCRs, which are engineered for general-purpose thyristor applications. The series offers various voltage and current ratings packaged in standard through-hole formats to facilitate easy integration into existing electronic designs requiring robust semiconductor switching solutions.
Replacement Considerations
Consult official Littelfuse substitution guides for verified equivalent parts. Ensure any alternative maintains identical voltage, current, and package specifications to guarantee functional compatibility without redesigning the host circuit board or driver interface.
