Overview
The CS220-8B is a Silicon Controlled Rectifier (SCR) from Central Semiconductor Corp, housed in a TO-220 case. It features an epoxy molded construction designed for sensing circuit and control system applications. The device supports a peak repetitive off-state voltage of 200 V and handles an RMS on-state current of 8.0 A at 90°C case temperature. Key electrical characteristics include a gate trigger current of 3.0 to 15 mA, holding current of 7.3 to 20 mA, and a critical rate of rise of on-state current of 50 A/μs. Operating junction temperature ranges from -40 to +125 °C.
Feature Summary
- Epoxy molded package construction suitable for sensing circuits
- High surge capacity with 60 A peak one cycle surge current capability
- Robust thermal performance with low thermal resistance values
Applications
- Sensing circuit applications
- Control system applications
Procurement Notes
Verify the End of Life status before procurement planning. The manufacturer indicates that no replacement part number is available for this specific component. Confirm final shipment dates and last purchase order deadlines directly with the supplier or authorized distributors to ensure supply continuity during transition periods.
Selection Notes
Select the CS220-8B when a 200 V blocking voltage and 8.0 A continuous current rating are required in a TO-220 package. Ensure the application design accounts for the specified gate trigger parameters and thermal management requirements given the 60 °C/W junction-to-ambient thermal resistance.
Part Context
This component belongs to the CS220 series of Silicon Controlled Rectifiers manufactured by Central Semiconductor Corp. The series includes variants with different voltage ratings, such as the CS220-8D, CS220-8M, and CS220-8N, which share similar current capabilities but offer higher voltage blocking thresholds up to 800 V.
Replacement Considerations
No direct replacement part numbers are listed by the manufacturer for the CS220-8B. Engineering support should be contacted for potential alternate sources or technical data to locate compatible substitutes.
