SJ6025L1TP

Overview

The SJ6025L1TP is a silicon controlled rectifier (SCR) manufactured by Littelfuse Inc., designed for high-power switching applications. It features a standard recovery characteristic and is housed in an ITO-220AB (TO-220-3) through-hole package. The device supports a rated repetitive off-state voltage of 600 V and an on-state RMS current of 25 A. Key electrical parameters include a gate trigger current of 6 mA, a holding current maximum of 15 mA, and a non-repetitive on-state current surge capability of 350 A. It operates within a junction temperature range up to +150°C.

Feature Summary

• Standard recovery thyristor construction for reliable switching performance
• Robust thermal management via TO-220AB through-hole mounting
• High surge current handling capability for transient protection

Applications

• Industrial motor control systems
• Power supply regulation circuits
• General purpose AC/DC power switching

Procurement Notes

Verify the specific suffix 'L1' against official Littelfuse documentation to confirm pinout configuration and exact electrical tolerances. Ensure the procurement channel provides valid traceability for the ITO-220AB package type. Cross-reference the datasheet revision date to confirm compliance with current industry standards before finalizing orders.

Selection Notes

Select this component when a 600 V blocking voltage and 25 A continuous current rating are required in a through-hole format. The 6 mA gate trigger sensitivity suits low-power drive interfaces. Consider the 350 A surge rating for applications involving high inrush currents or short-circuit conditions requiring robust fault tolerance.

Part Context

This part belongs to the Littelfuse SJ series of power SCRs, which are engineered for industrial and commercial power electronics. The SJ series emphasizes reliability in harsh environments, offering standardized packaging for easy integration into existing PCB layouts. It serves as a discrete solution for phase control and rectification tasks where high current density is essential.

Replacement Considerations

Direct substitutes may include SJ6025L2TP or SV6025L2QTP from the same manufacturer, provided voltage and current ratings align. Verify pin compatibility and thermal resistance characteristics before substitution. Alternative manufacturers require careful evaluation of gate trigger parameters and package dimensions to ensure functional equivalence.
