S8010R

Overview

The Littelfuse S8010R is a Silicon Controlled Rectifier (SCR) designed for high-power switching applications. It features an 800 V repetitive peak off-state voltage and handles a continuous RMS on-state current of 10 A. The device utilizes a TO-220AB flange mount package, facilitating efficient heat dissipation through the anode connection. Key electrical characteristics include a gate trigger voltage of 1.5 V and a gate trigger current of 15 mA. It operates within a temperature range of -40 °C to +125 °C and exhibits a forward voltage drop of 1.6 V at rated current.

Feature Summary

• Robust thermal management via direct flange mounting for high-current industrial environments
• High voltage blocking capability suitable for demanding power control circuits
• Standardized gate drive requirements simplifying interface with control logic

Applications

• Industrial motor speed control systems
• AC power regulation and phase control circuits
• Solid-state relay output stages

Procurement Notes

Verify the specific suffix against the manufacturer's datasheet to confirm exact pinout and mechanical dimensions. Ensure the procurement specification matches the required voltage and current ratings for the target application. Confirm RoHS compliance status if environmental regulations apply to the final assembly process.

Selection Notes

Select this component when an 800 V rating and 10 A continuous current capacity are required in a standard TO-220AB package. Consider the thermal resistance of the mounting surface and the necessity of an insulating washer if the circuit ground is connected to the heatsink. Evaluate the gate drive circuitry to ensure it can supply the specified 15 mA trigger current reliably.

Part Context

This SCR belongs to the Sxx10x series from Littelfuse, which provides standardized thyristor solutions for general-purpose power control. The series offers various voltage ratings while maintaining consistent current handling and package formats, allowing for design flexibility across different power levels without changing the mechanical footprint.

Replacement Considerations

Consult official substitution guides for equivalent SCRs with matching 800 V / 10 A ratings in TO-220AB packages. Verify that any alternative part meets the same gate trigger specifications and thermal performance requirements.
