Overview
The CS220-12D is a Silicon Controlled Rectifier (SCR) manufactured by Central Semiconductor Corp, designed for sensing circuit and control system applications. It features an epoxy molded construction in a TO-220 case with three leads: Cathode, Anode, and Gate, where the tab is common to the Anode. The device supports a peak repetitive off-state voltage of 400 V and handles an RMS on-state current of 12 A at 90°C. Key electrical characteristics include a gate trigger current of up to 15 mA, holding current of 20 mA, and a critical rate of rise of on-state current of 100 A/μs. Thermal resistance from junction to case is 2.5 °C/W, with an operating junction temperature range of -40 to +125 °C.
Feature Summary
- Epoxy molded package designed for robust performance in sensing and control systems
- Tab electrically connected to the Anode for efficient heat dissipation
- High surge current capability with 80 A one-cycle surge rating
Applications
- Sensing circuits
- Control system applications
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and lead-free availability if required by assembly specifications. Check for updated engineering change notices or product lifecycle changes before finalizing procurement plans.
Selection Notes
Select this component based on the specific 400 V blocking voltage requirement. Ensure thermal management design accommodates the 2.5 °C/W junction-to-case resistance. Verify that the gate drive circuit can supply sufficient current to meet the maximum 15 mA trigger requirement under all operating conditions.
Part Context
This part belongs to the CS220 series of Silicon Controlled Rectifiers, which covers voltage ratings from 200 V to 1000 V. The suffix 'D' specifically denotes the 400 V variant within this family. All variants share identical current ratings and physical packaging dimensions.
Replacement Considerations
The CS220-12D has been classified as End of Life (EOL) by Central Semiconductor Corp. No official replacement part number is provided in the manufacturer's documentation. Designers must identify alternate sources or equivalent components from other manufacturers.
