Overview
The Littelfuse S6SRP is a silicon-controlled rectifier (SCR) designed for surface-mount applications. It features a rated repetitive off-state voltage of 600 V and an RMS on-state current of 800 mA. The device operates within a temperature range of -40 °C to +110 °C. Key electrical parameters include a maximum gate trigger voltage of 0.8 V, a maximum DC gate trigger current of 0.2 mA, and a holding current of 5 mA. It exhibits a non-repetitive peak on-state current of 20 A and a forward voltage drop of 1.7 V. The component is housed in a DO-214AB (SMA) package with two terminals.
Feature Summary
- Sensitive gate triggering capability for low-power control circuits
- Surface-mount construction for automated assembly integration
- High surge current handling for transient protection scenarios
Applications
- General purpose switching in industrial control systems
- Overvoltage protection circuits
- Solid-state relay input stages
Procurement Notes
Verify the specific suffix and package variant against the manufacturer's latest datasheet before ordering. Confirm RoHS compliance status and lead times directly with authorized distributors. Ensure storage conditions meet moisture sensitivity level requirements to prevent package damage during soldering processes.
Selection Notes
Select this component when a compact surface-mount SCR is required for moderate current switching applications. Evaluate the gate trigger characteristics to ensure compatibility with the driving circuit's output capabilities. Consider the thermal management requirements based on the specified operating temperature range and power dissipation limits.
Part Context
This part belongs to the Littelfuse SxSx series of sensitive gate SCRs. These devices are engineered for high reliability in space-constrained designs. The series offers various voltage and current ratings to suit different power control needs while maintaining a consistent small outline footprint for PCB layout flexibility.
Replacement Considerations
Direct pin-to-pin replacements may be available from other manufacturers offering equivalent 600V 800mA SMA-packaged SCRs. Verify that substitute parts match the critical gate trigger voltage and current specifications to ensure proper circuit operation without modification.
