SJ4025NATP

Overview

The Littelfuse SJ4025NATP is a Silicon Controlled Rectifier (SCR) belonging to the SJxx25xx series. It features a rated repetitive off-state voltage (VDRM) of 400 V and an on-state RMS current (It RMS) of 12 A. The device has a gate trigger voltage (Vgt) of 1.5 V and operates within a temperature range of -40°C to +150°C. Packaged in a TO-263AB-3 surface mount format, it holds AEC-Q101 qualification for automotive reliability.

Feature Summary

AEC-Q101 qualified for automotive-grade reliability standards
High junction temperature capability up to 150°C
Surface-mount TO-263AB-3 package design

Applications

Automotive power control circuits
Industrial AC switching applications
General purpose thyristor protection systems

Procurement Notes

Verify the specific suffix against official Littelfuse documentation to confirm exact electrical tolerances and packaging variations. Confirm AEC-Q101 compliance status directly with the manufacturer or authorized distributors before integration into automotive designs.

Selection Notes

Select this component when a 400 V blocking voltage and 12 A continuous current rating are required in a compact SMD form factor. Ensure the application circuit can provide at least 1.5 V gate trigger voltage. Verify thermal management requirements for operation near the maximum 150°C junction limit.

Part Context

This part belongs to the SJxx25xx family of high-temperature SCRs from Littelfuse. These devices are designed for robust performance in demanding environments, offering a balance of voltage handling and current capacity in standard surface-mount packages suitable for automated assembly.

Replacement Considerations

Check Littelfuse datasheets for direct pin-compatible alternatives within the same voltage and current class. Verify that any substitute maintains the required AEC-Q101 qualification if used in automotive contexts.
