Overview
The CS220-12B is a Silicon Controlled Rectifier (SCR) manufactured by Central Semiconductor Corp, housed in a TO-220 case. It features a peak repetitive off-state voltage of 200 V and an RMS on-state current rating of 12 A at 90°C. The device supports a peak one-cycle surge current of 80 A and has a critical rate of rise of on-state current of 100 A/μs. Electrical characteristics include a gate trigger current of up to 15 mA and a holding current of up to 20 mA. Thermal resistance values are specified as 60 °C/W junction-to-ambient and 2.5 °C/W junction-to-case.
Feature Summary
- Epoxy molded construction designed for sensing circuit and control system applications
- High thermal efficiency with low junction-to-case thermal resistance
- Robust surge handling capability with defined I2t fusing value
Applications
- Sensing circuits
- Control systems
Procurement Notes
This component is classified as End of Life (EOL). No replacement part numbers are 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. Verify availability through authorized distributors or secondary markets if sourcing is required.
Selection Notes
Select this SCR based on its 200 V blocking voltage and 12 A continuous current capacity. Ensure the application environment maintains the case temperature below 90°C for full current rating. Consider the 100 A/μs di/dt limit during switching events. Since the product is discontinued, evaluate alternative SCRs with similar electrical parameters and TO-220 packaging for new designs.
Part Context
The CS220-12B belongs to the CS220 series of Silicon Controlled Rectifiers, which covers voltage ratings from 200 V to 1000 V. This specific model represents the 200 V variant within the lineup. The entire CS220 series has been transitioned to End of Life status by Central Semiconductor Corp due to declining customer demand.
Replacement Considerations
No official replacement part numbers are listed by the manufacturer. Engineering support can be contacted via email for assistance in locating alternate sources.
