SJ4025N2RP

Scrs Overview

The SJ4025N2RP is a Silicon Controlled Rectifier (SCR) manufactured by Littelfuse under the Teccor brand. It features a rated repetitive off-state voltage (VDRM) of 400 V and an on-state RMS current (It RMS) of 25 A. The device operates within a temperature range of -40°C to +150°C. Key electrical parameters include a gate trigger voltage (Vgt) of 1.5 V, a gate trigger current (Igt) of 35 mA, and a maximum holding current (Ih) of 50 mA. It exhibits a forward voltage drop (Vf) of 1.6 V and a non-repetitive peak on-state current of 350 A. The component utilizes an SMTO-263-2 surface mount package.

Scrs Feature Summary

• High junction temperature capability up to 150°C for robust thermal performance
• Surface mount construction in an SMTO-263-2 package for automated assembly
• Glass-passivated junctions to ensure long-term reliability and parameter stability

Scrs Applications

• AC power switching circuits
• Phase control applications
• General purpose thyristor switching

Scrs Procurement Notes

Verify the specific suffix 'N2' against official Littelfuse documentation to confirm exact manufacturing revisions or regional compliance variations. Ensure the ordering quantity aligns with the manufacturer's standard reel packaging requirements. Confirm RoHS and REACH status details directly from the latest datasheet before final procurement decisions.

Scrs Selection Notes

Select this component when a 400 V blocking voltage and 25 A continuous current capacity are required in a surface mount form factor. The 150°C maximum operating temperature distinguishes it from standard 125°C variants. Verify that the gate trigger characteristics match the driving circuit capabilities and that the SMTO-263-2 footprint fits the PCB layout constraints.

Scrs Part Context

This part belongs to the SJxx25xx series of high-temperature SCRs from Littelfuse. It shares the 400 V / 25 A rating profile with other members like SJ4025N1ATP but differs in package type and specific thermal ratings. The SJ series is designed for applications requiring higher thermal resilience compared to standard SCR offerings.

Scrs Replacement Considerations

Publicly confirmed substitute part numbers for SJ4025N2RP were not found in the provided source material. Cross-reference with SJ4025N1ATP only if package compatibility and thermal limits are verified through official Littelfuse substitution guides.
