Overview
The Central Semiconductor CS218I-30M is a Silicon Controlled Rectifier (SCR) rated for 600 V peak repetitive off-state voltage and 30 A RMS on-state current. It utilizes an isolated tab TO-218 package, providing 2500 V RMS isolation between the mounting tab and leads. The device supports a peak one-cycle surge current of 400 A and operates within a junction temperature range of -40 to +125 °C. Electrical characteristics include a gate trigger voltage of 1.5 V and a holding current of 75 mA.
Feature Summary
- Isolated mounting tab design ensures electrical separation from heatsinks
- Epoxy molded construction suitable for control system applications
- High thermal stability with low thermal resistance junction-to-case
Applications
- Sensing circuit protection
- Control system switching
- Industrial power regulation
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific plating options if required by assembly processes. Review datasheet specifications carefully to ensure compatibility with existing thermal management designs.
Selection Notes
Select this component based on the 600 V blocking requirement and 30 A continuous load capacity. Ensure the application environment allows for adequate heat dissipation given the TO-218 package constraints. Verify that the gate drive circuit can supply the necessary trigger current without exceeding peak power limits.
Part Context
This part belongs to the CS218I series of isolated tab SCRs manufactured by Central Semiconductor Corp. The series covers voltage ratings from 200 V to 1200 V in the TO-218 package. These devices are designed for robust performance in industrial environments requiring galvanic isolation.
Replacement Considerations
Official documentation classifies all CS218I-30 variants as End of Life (EOL). No specific replacement part numbers are listed for this model in the Product Discontinuation Notice. Designers must source alternative components from other manufacturers or redesign using available TO-247 equivalents.
