SK025RTP

Overview

The Littelfuse SK025RTP is a standard recovery silicon controlled rectifier (SCR) designed for phase control applications. It features a TO-220AB non-isolated package with three pins and a tab. The device supports an RMS on-state current of 25A and offers voltage ratings up to 1000V. It provides a non-repetitive surge current capability of 350A at 50Hz or 60Hz. The junction temperature range operates from -40°C to +125°C, with a maximum off-state leakage current of 20 µA.

Feature Summary

Standard phase control SCR suitable for heating and motor speed control circuits
High surge current capability for robust power handling
Non-isolated TO-220AB package design for efficient thermal management

Applications

Phase control applications
Heating system controls
Motor speed control systems

Procurement Notes

Verify the specific suffix designation against the manufacturer's official datasheet to confirm exact electrical parameters and package variations. Ensure compatibility with existing thermal management solutions due to the non-isolated TO-220AB form factor. Cross-reference the part number with authorized distributors to confirm availability and authenticity before procurement.

Selection Notes

Select this component for applications requiring reliable phase control with moderate current handling. Consider the 25A RMS rating and 1000V blocking voltage when designing circuit protection. Evaluate the thermal requirements for the TO-220AB package to ensure adequate heat dissipation in the target environment.
