Overview
The CS220-25P is a Silicon Controlled Rectifier from the Central Semiconductor CS220 series, housed in a TO-220 case. It features a maximum RMS on-state current of 25 A and peak repetitive off-state voltages ranging from 200 V to 800 V across the series variants. The device supports a peak one-cycle surge current of 250 A and has a critical rate of rise of on-state current (di/dt) rating of 100 A/μs. Operating junction temperature ranges from -40°C to +125°C with a thermal resistance (junction-to-case) of 1.3 °C/W.
Feature Summary
- Epoxy molded construction designed for sensing circuit and control system applications
- Tab is electrically common to the anode pin for mounting purposes
- Single element configuration with three-terminal lead arrangement
Applications
- Sensing circuits
- Control systems
Procurement Notes
Verify component authenticity through official manufacturer channels or authorized distributors. Confirm RoHS compliance status and check for specific ordering suffixes that may indicate lead-free plating options. Review datasheet revision history for updated electrical characteristics before finalizing procurement specifications.
Selection Notes
Select based on required voltage rating within the 200V to 800V range and ensure adequate heat sinking given the 1.3 °C/W thermal resistance. Verify gate trigger requirements against available drive circuitry. Consider the discontinued status when planning long-term production runs.
Part Context
The CS220-25P belongs to the broader CS220 family of silicon controlled rectifiers manufactured by Central Semiconductor Corp. This series includes multiple voltage variants such as CS220-25B, CS220-25D, CS220-25M, and CS220-25N, all sharing the same 25A current rating but differing in blocking voltage capabilities.
Replacement Considerations
The CS220-25P is classified as End of Life (EOL) with no direct replacement provided by Central Semiconductor. Designers must source alternative SCRs from other manufacturers that match the 25A current rating, TO-220 package, and specific voltage requirements.
