SK055RTP

Scrs Overview

The Littelfuse SK055RTP is a Silicon Controlled Rectifier (SCR) designed for high-power switching applications. It features a maximum repetitive peak reverse voltage of 1000 V and a maximum average on-state current of 55 A. The device utilizes a TO-220AB plastic package with a flange mount configuration, ensuring secure mechanical attachment for thermal management. As a single-element thyristor, it provides robust performance in industrial environments requiring reliable power control.

Scrs Feature Summary

• High-voltage blocking capability suitable for demanding power circuits
• Robust thermal dissipation through flange-mounted construction
• Standardized TO-220AB package for easy integration

Scrs Applications

• Industrial motor speed control systems
• AC power regulation circuits
• Solid-state relay implementations

Scrs Procurement Notes

Verify the specific manufacturer source when ordering, as multiple vendors including Teccor Electronics and ISC may list this part number. Confirm that the TP suffix corresponds to the required RoHS compliance and packaging details specified by your supply chain requirements before finalizing procurement.

Scrs Selection Notes

Select this component based on its 1000 V reverse voltage rating and 55 A current handling capacity. Ensure the circuit design accommodates the thermal resistance characteristics inherent to the TO-220AB flange mount package for adequate heat sinking during continuous operation.

Scrs Part Context

This SCR belongs to the broader family of silicon controlled rectifiers used for AC power switching. Variants such as SK055R56 or SK055RTP56 exist within the same product line, often differing in specific compliance markings or minor packaging attributes while maintaining core electrical specifications.

Scrs Replacement Considerations

Cross-reference with SK055R56 or SK055RTP56 from Littelfuse for potential substitutes. Verify pinout compatibility and thermal performance equivalence before replacing the original component in existing designs.
