CS220-25PB

Scrs Overview

The Central Semiconductor CS220-25PB is a Silicon Controlled Rectifier (SCR) from the CS220 series, housed in a TO-220 package. It features a peak repetitive off-state voltage of 800 V and an RMS on-state current of 25 A at 90°C case temperature. The device supports a peak one-cycle surge current of 250 A and has a critical rate of rise of on-state current of 100 A/μs. Operating junction temperature ranges from -40 to +125 °C, with storage temperatures up to +150 °C. Thermal resistance values are 60 °C/W (junction-to-ambient) and 1.3 °C/W (junction-to-case).

Scrs Feature Summary

• Epoxy molded construction designed for sensing circuit and control system applications.
• Single element silicon controlled rectifier configuration with tab common to the anode.

Scrs Applications

• Sensing circuits
• Control systems
