SK065KTP

Scrs Overview

The SK065KTP is a standard phase control silicon controlled rectifier (SCR) manufactured by Littelfuse Inc. It features a 1 kV repetitive peak forward blocking voltage and an on-state RMS current rating of 65 A. The device has a gate trigger current of 50 mA and a holding current maximum of 80 mA. It operates within a temperature range of -40 °C to 125 °C. The component utilizes a TO-218AC through-hole package with three pins and an isolated tab for mounting.

Scrs Feature Summary

• Standard phase control SCR design suitable for unidirectional switching applications
• High voltage blocking capability up to 1 kV for robust circuit protection
• Through-hole mounting configuration with isolated tab for thermal management

Scrs Applications

• Phase control applications in heating systems
• Motor speed control circuits
• General purpose AC power switching

Scrs Procurement Notes

Verify the specific datasheet version from Littelfuse or authorized distributors to confirm exact electrical characteristics and mechanical dimensions. Ensure the TO-218AC package matches the target PCB footprint and thermal requirements. Check for any recent product lifecycle changes or obsolescence notices before finalizing procurement plans.

Scrs Selection Notes

Select this component when a 1 kV blocking voltage and 65 A RMS current are required for phase control tasks. Consider the 50 mA gate trigger current for driver compatibility. The TO-218AC package dictates the physical layout constraints. Evaluate thermal dissipation needs based on the 125 °C maximum operating temperature limit.

Scrs Part Context

The SK065KTP belongs to the Sxx65x product range, which includes low power SCRs rated up to 1200 V. This series is designed for applications requiring reliable unidirectional switching. The part shares family characteristics with other devices in the Sxx65x lineup, differing primarily in specific voltage and current ratings.
