Overview
The CS220-25M is a Silicon Controlled Rectifier from the Central Semiconductor CS220 series, housed in a TO-220 case. It features a peak repetitive off-state voltage of 600 V and an RMS on-state current of 25 A at 90°C. The device supports a peak one-cycle surge current of 250 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 30 mA and a holding current of up to 50 mA. Thermal resistance junction-to-case is 1.3 °C/W, with an operating junction temperature range of -40 to +125 °C.
Feature Summary
- Epoxy molded construction designed for sensing circuit and control system applications
- Tab is electrically common to the anode pin for mounting purposes
- Capable of handling high surge currents and rapid current rise rates
Applications
- Sensing circuits
- Control systems
Procurement Notes
This component is classified as End of Life (EOL) by Central Semiconductor Corp. No replacement part number is currently available within the manufacturer's lineup. Procurement should focus on verifying stock availability through authorized distributors or exploring alternative sources via engineering support, as standard production has ceased.
Selection Notes
Select this component only if the specific 600 V rating and 25 A current capacity match the design requirements. Verify that the TO-220 package and thermal management capabilities meet the application's constraints. Due to the EOL status, confirm long-term supply feasibility before finalizing the design.
Part Context
The CS220-25M belongs to the broader CS220 series of SCRs, which share identical electrical ratings except for the peak repetitive off-state voltage. Variants in this series offer voltages ranging from 200 V to 800 V, allowing designers to choose the appropriate blocking voltage while maintaining the same 25 A current handling and package form factor.
Replacement Considerations
No direct replacement part number is listed by Central Semiconductor for the CS220-25M. Designers must seek alternate sources or equivalent components from other manufacturers that match the 600 V, 25 A SCR specifications in a TO-220 package.
