S4010DTP

Overview

The Littelfuse S4010DTP is a Silicon Controlled Rectifier (SCR) belonging to the Sxx10xSx series, rated for a repetitive peak off-state voltage of 400 V and an RMS on-state current of 10 A. It features a sensitive gate with a maximum gate trigger current of 500 uA and a gate trigger voltage of 800 mV. The device operates within a junction temperature range of -40 °C to +110 °C and is housed in a TO-220AB package.

Feature Summary

• Sensitive gate architecture enabling reliable triggering with low control power
• Robust thermal management capabilities via flange mount packaging
• High surge current handling capability for transient protection

Applications

• Solid state relays
• Industrial motor controls
• Power supply circuits

Procurement Notes

Verify the specific manufacturer datasheet for the S4010DTP to confirm exact pinout configurations and mechanical dimensions. Ensure compliance with RoHS directives and check for any specific environmental certifications required by the target application before finalizing procurement orders.

Selection Notes

Select this component when a 10 A SCR with a 400 V rating is required in a through-hole TO-220AB package. The sensitive gate characteristic makes it suitable for applications where minimal gate drive current is available or desired, simplifying the control circuit design compared to standard gate devices.

Part Context

This part belongs to the Littelfuse Sxx10xSx family of SCRs, which are designed for general purpose power control. The 'D' suffix typically indicates a specific gate sensitivity level or variant within the 10 A current rating bracket, distinguishing it from other packages like TO-220 or DPAK variants in the same series.

Replacement Considerations

Direct replacements include the S4010LS2TP and S4010RS2TP, provided the TO-220AB package and 10 A/400 V ratings match the design requirements. Verify that the replacement's gate trigger characteristics align with the existing control circuitry.
