SJ4025NTP

Scrs Overview

The Littelfuse SJ4025NTP is a Silicon Controlled Rectifier (SCR) belonging to the SJxx25xx series, designed for high-power switching applications. 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 utilizes a gate trigger voltage (Vgt) of 1.5 V for activation. It operates within a temperature range from -40°C to +150°C and is housed in a surface-mount TO-263AB-3 package. The component is qualified under the AEC-Q101 standard, ensuring reliability for automotive environments.

Scrs Feature Summary

• AEC-Q101 qualified for automotive-grade reliability
• High junction temperature capability up to 150°C
• Surface-mount TO-263AB-3 packaging for automated assembly

Scrs Applications

• Automotive power control circuits
• Industrial motor drives
• AC/DC power conversion systems

Scrs Procurement Notes

Verify the specific suffix against official Littelfuse documentation to confirm exact electrical tolerances and thermal characteristics. Confirm that the TO-263AB-3 package matches the target PCB footprint requirements. Ensure the 12 A RMS rating aligns with the system's continuous load demands. Check for any recent Product Change Notifications (PCNs) affecting material composition or manufacturing location.

Scrs Selection Notes

Select this component when a surface-mount SCR with automotive qualification is required. Compare the 12 A RMS current rating against peak load requirements to ensure adequate margin. Consider the 400 V blocking voltage relative to the maximum circuit transient voltages. Evaluate the thermal resistance of the TO-263AB-3 package for the intended heat dissipation environment.

Scrs Part Context

This part belongs to the Littelfuse SJ series of thyristors, specifically engineered for robust performance in demanding electronic applications. The SJ4025NTP variant offers a balance of moderate current handling and high voltage blocking in a compact surface-mount form factor. It serves as a specialized solution within the broader Littelfuse power control portfolio.

Scrs Replacement Considerations

Consult Littelfuse official substitution guides for verified equivalents. Generic thyristor replacements may not meet the AEC-Q101 automotive qualification or the specific 150°C junction temperature rating.
