Overview
The CS220-12M is a Silicon Controlled Rectifier (SCR) 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 rating of 12 A at 90°C. The device supports a peak one-cycle surge current of 80 A with an I²t value of 32 A²s for fusing. Electrical characteristics include a gate trigger current of 3.5 to 15 mA and a holding current of 8.7 to 20 mA. Operating junction temperature ranges from -40 to +125 °C, with thermal resistance values of 60 °C/W (junction-to-ambient) and 2.5 °C/W (junction-to-case).
Feature Summary
- Epoxy molded construction designed for sensing circuit and control system applications.
- High surge current capability with defined di/dt ratings for robust switching performance.
- Standardized pinout configuration with cathode, anode, and gate leads.
Applications
- Sensing circuits
- Control systems
Procurement Notes
This component has been officially classified as End of Life by Central Semiconductor Corp. No replacement part numbers are currently available within the manufacturer's lineup. Procurement should focus on verifying existing inventory levels or consulting engineering support for potential alternate sourcing strategies, as standard production has ceased.
Selection Notes
Selection requires matching the 600 V blocking voltage and 12 A continuous current requirements. Designers must account for the TO-220 package thermal constraints, utilizing appropriate heatsinking to maintain junction temperatures within the specified operating range during high-current operation.
Part Context
The CS220-12M belongs to the broader CS220 series of SCRs, which offers voltage ratings ranging from 200 V to 1000 V while maintaining a consistent 12 A current rating across variants. This specific model represents the 600 V option within that family.
Replacement Considerations
Central Semiconductor lists no direct replacement part number for the CS220-12M. Engineers are advised to contact the manufacturer's engineering team for assistance in locating an alternate source or suitable substitute component.
FAQ
What is the maximum peak forward gate power dissipation?
The peak forward gate power dissipation is rated at 40 W for a pulse width of 10 μs.
How is the lead configuration arranged in the TO-220 package?
Pin 1 is the Cathode, Pin 2 is the Anode, and Pin 3 is the Gate. The tab is electrically common to the Anode (Pin 2).
What is the critical rate of rise of on-state current?
The critical rate of rise of on-state current (di/dt) is 100 A/μs.
