SJ4025L2TP

Scrs Overview

The Littelfuse SJ4025L2TP is a Silicon Controlled Rectifier (SCR) belonging to the SJxx25xx series, designed for high-temperature environments. 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 operates within a temperature range of -40°C to +150°C. Key electrical parameters include a forward voltage (Vf) of 1.6 V, a gate trigger voltage (Vgt) of 1.5 V, and a gate trigger current (Igt) of 10 mA. It utilizes a TO-263AB-3 surface mount package.

Scrs Feature Summary

• High-temperature operation capability up to +150°C
• Surface-mount installation in TO-263AB-3 package
• Glass-passivated junctions for parameter stability

Scrs Applications

• AC power control circuits
• Phase control applications
• Industrial motor drives

Scrs Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm pinout and thermal characteristics. Ensure the procurement channel provides valid traceability documentation. Confirm that the component meets RoHS compliance requirements as specified in the latest Littelfuse product announcements before finalizing purchase orders.

Scrs Selection Notes

Select this SCR based on its 400 V blocking voltage and 12 A RMS current rating relative to the circuit load requirements. The TO-263AB-3 package is suitable for surface-mount assembly processes. Evaluate the thermal management needs given the high-temperature rating and ensure the gate drive circuit can supply the required 10 mA trigger current reliably under all operating conditions.

Scrs Part Context

This component is part of the Littelfuse SJxx25xx series of thyristors. The series is characterized by high-temperature performance and robust construction. These devices are engineered for reliable switching in demanding industrial and commercial power electronics applications where thermal stability is critical.

Scrs Replacement Considerations

Consult the Littelfuse official cross-reference guide for verified substitutes. Ensure any replacement maintains the same 400 V rating, 12 A current capacity, and TO-263AB-3 package footprint to guarantee mechanical and electrical compatibility without redesigning the PCB layout.
