SJ6012LTP

Scrs Overview

The Littelfuse SJ6012LTP is a Silicon Controlled Rectifier (SCR) designed for through-hole mounting in the TO-220L package. It features a repetitive peak reverse voltage of 600 V and an average on-state current rating of 12 A. The device supports a surge current capacity of 120 A, with a maximum gate trigger current of 6 mA and a maximum gate trigger voltage of 1.5 V. Operating within a temperature range from -40°C to 150°C, it maintains a holding current of 35 mA. This component is RoHS compliant and belongs to the SVxx12xx series, providing reliable power control capabilities.

Scrs Feature Summary

• High surge current capability of 120 A for robust transient handling
• Wide operating temperature range from -40°C to 150°C
• Low gate trigger current requirement of 6 mA for efficient drive circuits

Scrs Applications

• Industrial power control systems
• AC motor speed control circuits
• Lighting dimmer applications

Scrs Procurement Notes

Verify the specific suffix 'TP' against official Littelfuse documentation to confirm tape-and-reel packaging or specific variant details. Ensure the TO-220L lead form matches the target PCB footprint requirements. Cross-reference the 600V/12A ratings with the actual circuit load conditions to prevent derating issues during operation.

Scrs Selection Notes

Select this SCR when a 600V blocking voltage and 12A continuous current are required in a standard TO-220L package. Consider the 6mA gate trigger current for driver compatibility. Evaluate thermal management needs given the 150°C junction limit. Verify that the 120A surge rating exceeds the expected inrush currents in the specific application environment.

Scrs Part Context

This component is part of the Littelfuse SVxx12xx series of silicon controlled rectifiers. These devices are engineered for general-purpose power switching applications requiring high reliability and robust performance in industrial and commercial environments.

Scrs Replacement Considerations

Consult Littelfuse official substitution guides for verified equivalents. Generic replacements must match the 600V Vrrm, 12A IT(AV), and TO-220L package constraints.
