S8X8TSRP

Overview

The Littelfuse S8X8TSRP is a Silicon Controlled Rectifier (SCR) from the SxX8xSx series, designed for surface-mount applications in the SOT-223-3 package. It features an 800V rated repetitive off-state voltage and supports an RMS on-state current of 800mA with an average current capacity of 510mA. The device requires a gate trigger voltage of 800mV and a current of 200µA to activate. It exhibits a forward voltage drop of 1.7V and maintains a maximum holding current of 5mA. The component operates within a temperature range of -40°C to +125°C and withstands a non-repetitive peak surge current of 10A.

Feature Summary

High reliability construction suitable for demanding environments
Integrated thermal management via exposed anode tab design
Low gate sensitivity enabling efficient drive circuit integration

Applications

AC power control circuits
Lighting dimmer systems
Motor speed control applications

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct packaging configuration. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer before placing orders. Ensure the procurement channel provides valid traceability documentation for quality assurance purposes.

Selection Notes

Select this component when a surface-mount SCR with 800V blocking capability is required. Verify that the load current does not exceed the 800mA RMS rating under expected operating temperatures. Ensure the gate drive circuit can supply at least 200µA at 800mV to guarantee reliable triggering during operation.

Part Context

This part belongs to the Littelfuse SxX8xSx series of silicon controlled rectifiers. These devices are engineered for general-purpose AC switching and phase control tasks. The series offers various voltage and current ratings packaged in standard surface-mount footprints to facilitate automated assembly and compact board designs.

Replacement Considerations

Direct substitutes must match the 800V VDRM, 800mA IT(RMS), and SOT-223-3 package constraints. Verify pinout compatibility and thermal characteristics before substitution.
