S4010DRP

Scrs Overview

The S4010DRP is a Silicon Controlled Rectifier (SCR) manufactured by Littelfuse, designed for surface-mount applications in the TO-252-3 package. It features a rated repetitive off-state voltage (VDRM) of 400 V and an on-state RMS current (It RMS) of 10 A. The device has a maximum gate trigger current (Igt) of 500 uA and a holding current (Ih) of 8 mA. Operating within a temperature range of -40 C to +110 C, it exhibits a forward voltage drop (Vf) of 1.6 V and a non-repetitive peak on-state current of 100 A.

Scrs Feature Summary

• Surface-mount construction in a compact TO-252-3 package for automated PCB assembly
• Sensitive gate triggering capability with low gate current requirements
• High thermal stability suitable for demanding industrial environments

Scrs Applications

• General purpose power control circuits
• Lighting dimming systems
• Motor speed control applications

Scrs Procurement Notes

Verify the specific suffix DRP against official Littelfuse documentation to confirm the reel packaging configuration. Ensure the ordering quantity aligns with standard manufacturing reel sizes. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing procurement orders.

Scrs Selection Notes

Select this component when a 400 V blocking voltage and 10 A continuous current rating are required in a surface-mount form factor. The sensitive gate characteristic makes it suitable for low-power drive circuits. Verify that the TO-252-3 thermal dissipation capabilities meet the specific application's heat management requirements under expected load conditions.

Scrs Part Context

This SCR belongs to the Littelfuse Sxx10xSx series, which provides robust thyristor solutions for general-purpose power switching. The series is engineered for reliability in consumer and industrial electronics, offering standardized electrical characteristics across various voltage and current ratings within the same package family.

Scrs Replacement Considerations

Direct replacements include other 400 V, 10 A SCRs in TO-252 packages from Littelfuse or compatible manufacturers. Verify pinout compatibility and ensure equivalent gate sensitivity and thermal resistance specifications are met to maintain circuit performance.
