S8025R

Overview

The S8025R is a standard recovery silicon controlled rectifier (SCR) manufactured by Littelfuse Inc. It features an 800 V repetitive peak reverse voltage rating and a 25 A average on-state current capability. The device utilizes a TO-220 Non-Isolated Tab package for through-hole mounting. It operates with a maximum junction temperature of 125°C and supports surge currents up to 100A, providing reliable performance for phase control applications.

Feature Summary

• Functions as an excellent unidirectional switch for phase control circuits
• Designed for sensitive gate triggering in heating and motor speed controls
• Provides high surge current capability for robust operation

Applications

• Heating control systems
• Motor speed controls
• Phase control applications

Procurement Notes

Verify the specific ordering suffix matches the required package and thermal characteristics. Confirm that the non-isolated tab configuration aligns with the intended circuit isolation requirements. Ensure the selected component meets the necessary voltage and current ratings for the specific application environment before finalizing procurement.

Selection Notes

Select this component for applications requiring standard phase control switching with moderate power handling. Consider the TO-220 package constraints regarding thermal management and mounting space. Evaluate the 800V blocking voltage against peak line voltages to ensure adequate safety margins during operation.

Part Context
