Overview
The CS220-25N 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 800 V and an RMS on-state current rating of 25 A at a case temperature of 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 maximum gate trigger voltage of 1.5 V 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
- High thermal stability with low junction-to-case thermal resistance
- Robust surge current handling capability for industrial power control
Applications
- Sensing circuits
- Control systems
- Industrial power control
Procurement Notes
This component is classified as End of Life (EOL). No replacement part number is available from the manufacturer. Last purchase orders must be placed within six months of the notice date, with final shipments occurring twelve months after the notice. Contact engineering support for technical data or alternate source assistance if inventory is exhausted.
Selection Notes
Select this SCR for high-voltage applications requiring 800 V blocking capability and 25 A continuous conduction. Ensure adequate heatsinking to maintain case temperatures below 90°C for full current rating. Verify gate drive requirements against the specified trigger voltage and current limits. Consider the EOL status when designing new products due to supply constraints.
Part Context
The CS220-25N belongs to the CS220 series of SCRs manufactured by Central Semiconductor Corp. This series covers voltage ratings from 200 V to 1000 V with a consistent 25 A current rating across variants like CS220-25B, CS220-25D, and CS220-25M. All units share the same TO-220 package and general electrical profile, differing primarily in their voltage blocking capabilities.
Replacement Considerations
No direct replacement part number is provided by Central Semiconductor for the CS220-25N. The manufacturer indicates that no substitute is currently available. Designers should consult the manufacturer's engineering team for potential alternate sources or equivalent components from other suppliers.
