CS220-10B

Scrs Overview

The CS220-10B is a Silicon Controlled Rectifier (SCR) from Central Semiconductor Corp, housed in a TO-220 package. It features a peak repetitive off-state voltage of 200 V and an RMS on-state current rating of 10 A at 90°C case temperature. The device supports a peak one-cycle surge current of 100 A and has a critical rate of rise of on-state current (di/dt) of 50 A/μs. Electrical characteristics include a gate trigger voltage of 1.5 V and holding current of 30 mA. Operating junction temperature ranges from -40 to +125 °C.

Scrs Feature Summary

• Epoxy molded construction designed for sensing circuit and control system applications
• High thermal stability with low thermal resistance between junction and case
• Robust surge handling capability with defined fusing I²t value

Scrs Applications

• Sensing circuits
• Control systems

Scrs Procurement Notes

This component is officially classified as End of Life by the manufacturer. No replacement part number is currently available from Central Semiconductor Corp. Procurement should focus on verifying existing inventory or identifying alternative sources through direct engineering support channels, as standard distribution availability is not guaranteed.

Scrs Selection Notes

Select this SCR when a 200 V blocking voltage and 10 A continuous current capacity are required in a TO-220 form factor. Ensure the application can accommodate the specified gate trigger parameters and thermal management requirements given the discontinuation status. Verify that the 50 A/μs di/dt rating meets the circuit's switching speed constraints.

Scrs Part Context

The CS220-10B belongs to the CS220 series of silicon controlled rectifiers, which covers voltage ratings from 200 V to 800 V. This specific model represents the lowest voltage option within the 10 A current class of the series. The series shares common mechanical outlines and electrical testing conditions across its variants.

Scrs Replacement Considerations

No official replacement part number is listed by Central Semiconductor Corp for the CS220-10B. Engineers must seek alternate sources or equivalent devices from other manufacturers, as no direct substitute is provided in the product documentation.
