S4010NS3TP

Overview

The S4010NS3TP is a silicon-controlled rectifier (SCR) manufactured by Littelfuse, designed for surface-mount applications. It features a D2PAK-3 (TO-263-3) package and operates within a temperature range of -40°C to +110°C. Key electrical parameters include 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 holding current (Ih) of 6 mA and supports a non-repetitive on-state peak current of 100 A. Gate triggering specifications consist of a gate trigger voltage (Vgt) of 800 mV and a gate trigger current (Igt) of 200 uA. The forward voltage (Vf) is specified at 1.6 V, with an off-state leakage current of 5 uA under VDRM conditions.

Feature Summary

• Surface-mount construction in a D2PAK-3 (TO-263-3) package for automated PCB assembly
• Sensitive gate structure enabling reliable triggering with low gate current requirements
• Robust thermal and electrical performance suitable for industrial power control environments

Applications

• Industrial motor speed control systems
• AC power regulation circuits
• Solid-state relay implementations

Procurement Notes

Verify the specific suffix 'S3' against official Littelfuse documentation to confirm pinout configuration and package variant accuracy. Ensure compatibility with standard TO-263 footprints during layout design. Confirm RoHS compliance status through the manufacturer's latest product change notifications or datasheet revision history before finalizing procurement plans.

Selection Notes

Select this component when a 400 V blocking capability and 10 A continuous current rating are required in a compact surface-mount form factor. The sensitive gate characteristic simplifies drive circuit design compared to standard gate devices. Verify that the D2PAK-3 package provides adequate thermal dissipation for the intended application's duty cycle and ambient temperature conditions.

Part Context

This SCR belongs to the Sxx10xSx series from Littelfuse, which offers various voltage ratings and package options within the same family. The S4010NS3TP specifically combines the 400 V / 10 A electrical profile with the three-terminal D2PAK-3 package. Other variants in this series may differ in voltage rating, package type, or gate sensitivity characteristics.

Replacement Considerations

Cross-reference with other Littelfuse S4010 series parts such as S4010DS3TP or S4010NS2TP for package or gate sensitivity differences. Verify pinout compatibility and thermal resistance values when substituting with equivalent SCRs from other manufacturers.

FAQ

What is the difference between the S4010NS3TP and S4010NS3RP?
