CS220-10N Equivalent & Substitute Parts

Part Overview

The CS220-10N is an 800V 10A SCR (Silicon Controlled Rectifier) in TO-220-3 package manufactured by Central Semiconductor Corp. This thyristor is designed for standard recovery applications requiring high voltage blocking capability and moderate current handling. The part is currently obsolete, making identification of compatible substitutes essential for ongoing system support and component procurement.

Substitute Part Grouping Explanation

Substitution of the CS220-10N is determined by matching the following critical electrical and mechanical parameters:

Off-state voltage rating: 800V minimum
RMS on-state current capability: 10A minimum
Gate trigger voltage: 1.5V maximum
Gate trigger current: 15mA maximum
On-state voltage drop: 1.6V maximum
Hold current: 30mA maximum
SCR recovery type: Standard Recovery
Package configuration: TO-220-3 through-hole
Operating temperature range: -40°C to 125°C

The TYN810RG from STMicroelectronics meets all specified electrical parameters and maintains identical package and mounting characteristics, establishing it as a direct functional equivalent.

Engineering Selection Recommendations

The TYN810RG is the appropriate substitute for the obsolete CS220-10N based on complete electrical parameter equivalence and identical mechanical specifications. The substitute maintains active product status with STMicroelectronics, ensuring long-term availability and supply chain continuity. The TYN810RG carries ROHS3 compliance certification, meeting current environmental and regulatory requirements. Both components share identical TO-220-3 through-hole packaging, permitting direct board-level replacement without layout modification.

Frequently Asked Questions (FAQ)

Q: Can the TYN810RG be used as a direct replacement for CS220-10N in existing designs?

A: Yes. The TYN810RG matches all critical electrical parameters including voltage rating, current capacity, gate trigger specifications, and on-state characteristics. Package and mounting type are identical, enabling direct substitution without circuit redesign.

Q: Are there differences in current ratings between these parts?

A: Both parts are rated for 10A RMS on-state current. The TYN810RG specifies additional current parameters (6.4A average and 100-105A non-repetitive surge), providing supplementary performance data not listed for the CS220-10N.

Q: What is the significance of the CS220-10N being obsolete?

A: Obsolete status indicates the part is no longer manufactured by Central Semiconductor Corp. The TYN810RG, with active product status, provides continued availability and manufacturing support for equivalent functionality.

Q: Are there packaging or thermal considerations for this substitution?

A: Both components use TO-220-3 through-hole packaging with identical thermal and mechanical interfaces. Thermal management and board layout considerations remain unchanged between the original and substitute part.

Q: Does the TYN810RG meet current compliance standards?

A: The TYN810RG is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements applicable to electronic components.
