CS220-16P

Overview

The CS220-16P is a Silicon Controlled Rectifier (SCR) from the Central Semiconductor CS220 series, housed in a TO-220 case. It supports an RMS on-state current of 16 A and a peak one-cycle surge current of 160 A. The device offers a peak repetitive off-state voltage rating of 800 V. Key electrical characteristics include a gate trigger current of up to 15 mA, a holding current of 20 mA, and a maximum gate trigger voltage of 1.5 V. Thermal resistance values are specified at 2.5 °C/W junction-to-case and 60 °C/W junction-to-ambient.

Feature Summary

• Epoxy molded construction designed for sensing circuit and control system applications
• Tab electrically common with the cathode lead for mounting purposes

Applications

• Sensing circuits
• Control systems

Procurement Notes

Verify component status before procurement as the CS220 series has been transitioned to End of Life status by Central Semiconductor Corp. Confirm availability through authorized distributors or secondary markets, noting that final shipments may be subject to specific cutoff dates defined in official discontinuation notices.

Selection Notes

Select this component based on its 800 V blocking capability and 16 A continuous current handling within the TO-220 package. Ensure thermal management meets the specified junction-to-case resistance requirements. Verify compatibility with gate drive parameters, specifically the 15 mA trigger current limit and 40 W peak gate power dissipation constraints.

Part Context

This part belongs to the CS220 series of Silicon Controlled Rectifiers manufactured by Central Semiconductor Corp. The series covers various voltage ratings from 200 V to 800 V while maintaining a consistent 16 A current rating across different suffixes representing distinct voltage classes.

Replacement Considerations

Official documentation lists no direct replacement part numbers for the CS220-16P. Engineering support should be contacted for alternate source recommendations if sourcing new units is required.
