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).
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.
Applications
- Sensing circuits
- Control systems
Procurement Notes
This component is classified as End of Life by Central Semiconductor Corp. No replacement part number is currently available from the manufacturer. Last purchase orders must be placed within six months of the notice date, with final shipments occurring twelve months after the notice. Contact [email protected] for technical data or alternate source assistance.
Selection Notes
Select this SCR based on its 800 V blocking capability and 25 A continuous current rating. Ensure thermal management accommodates the specified thermal resistances. Verify that gate trigger requirements align with the typical 30 mA IGT and 1.5 V VGT maximums provided in the electrical characteristics table.
Part Context
The CS220-25PB belongs to the CS220 series of 25 Amp Silicon Controlled Rectifiers offered by Central Semiconductor Corp. This series includes variants with different voltage ratings ranging from 200 V to 800 V, all sharing the same TO-220 mechanical outline and general electrical performance profile.
Replacement Considerations
No official replacement part number is listed by Central Semiconductor for the CS220-25PB. Users requiring a substitute should consult the manufacturer's engineering team for potential alternate sources or equivalent specifications from other vendors.
