CS220-16D

Scrs Overview

The Central Semiconductor Corp CS220-16D is a Silicon Controlled Rectifier (SCR) housed in a TO-220 case. It features a peak repetitive off-state voltage of 400 V and an RMS on-state current rating of 16 A at 90°C. The device supports a peak one-cycle surge current of 160 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, holding current up to 20 mA, and a forward voltage drop of 1.6 V at 32 A. Thermal resistance values are 60 °C/W junction-to-ambient and 2.5 °C/W junction-to-case.

Scrs Feature Summary

• Epoxy molded construction designed for sensing circuit and control system applications
• Tab electrically common with the anode for mounting purposes
• Capable of handling high surge currents and rapid current rise rates

Scrs Applications

• Sensing circuits
• Control systems

Scrs Procurement Notes

Verify component status before procurement as the CS220 series is classified as End of Life. Confirm availability through official channels or authorized distributors. Request technical data from [email protected] if sourcing assistance is required. Ensure compliance with RoHS standards and check for specific plating options if needed.

Scrs Selection Notes

Select the CS220-16D when a 400 V blocking voltage and 16 A continuous current capability are required in a TO-220 package. Consider thermal management due to the specified junction-to-case thermal resistance. Evaluate gate drive requirements against the maximum trigger current and voltage specifications to ensure reliable triggering under operating conditions.

Scrs Part Context

The CS220-16D belongs to the CS220 series of Silicon Controlled Rectifiers manufactured by Central Semiconductor Corp. This series includes variants with different voltage ratings such as 200 V, 600 V, and 800 V. All devices share similar current ratings and packaging but differ in their peak repetitive off-state voltage capabilities.

Scrs Replacement Considerations

No replacement part numbers are available for the CS220-16D. The manufacturer indicates that no direct substitute is provided within their portfolio for this discontinued series.
