S6012LTP

Overview

The Littelfuse S6012LTP is a silicon-controlled rectifier (SCR) from the Sxx12x series, designed for uni-directional switching applications. It features a 600 V repetitive peak reverse voltage and an average on-state current rating of 12 A. The device utilizes a TO-220-2 package with through-hole mounting and supports junction temperatures up to 150°C. Key electrical characteristics include a maximum gate trigger current of 6 mA and a non-repetitive surge current capability of 120 A at 50/60 Hz. The component exhibits low off-state leakage current and is compliant with RoHS standards.

Feature Summary

• Sensitive gate architecture enabling direct interfacing with microprocessors via low gate trigger current requirements.
• High thermal stability supporting continuous operation at elevated junction temperatures up to 150°C.
• Robust surge handling capability suitable for inrush current control and capacitive discharge ignition systems.

Applications

• Phase control in heating systems
• Motor speed controls
• Converters and rectifiers
• Inrush current control circuits
• Capacitive discharge ignitions

Procurement Notes

Verify the specific suffix 'TP' against official Littelfuse documentation to confirm packaging details, as standard datasheets may list bulk or tube variations without explicit tape-and-reel confirmation. Ensure the part number matches the exact voltage and current ratings required for the target circuit design before ordering.

Selection Notes

Select this component for applications requiring high junction temperature tolerance and sensitive gate drive compatibility. Compare the 12 A RMS current rating and 600 V blocking voltage against circuit demands. Consider the TO-220-2 package constraints for thermal management and PCB layout requirements relative to alternative surface mount options.

Part Context

The S6012LTP belongs to the Littelfuse Sxx12x series of high junction temperature SCRs. This family is engineered for reliable performance in demanding power control environments. The device shares core specifications with other variants in the series, differing primarily in packaging or minor parameter tolerances defined by manufacturer revisions.

Replacement Considerations

Direct replacements within the same series include SV6012L1TP for surface mount configurations or S6012LS2TP for sensitive gate variants. Verify pinout compatibility and thermal resistance values when substituting to ensure equivalent circuit performance and mechanical fit.
