CS220-12N Equivalent & Substitute Parts

Part Overview

The CS220-12N is an 800V 12A Standard Recovery SCR (Silicon Controlled Rectifier) in TO-220-3 through-hole packaging, manufactured by Central Semiconductor Corp. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The part operates across a temperature range of -40°C to 125°C and is suitable for applications requiring high-voltage thyristor switching functionality.

Substitute Part Grouping Explanation

Substitution of the CS220-12N is determined by the following critical parameters:

Voltage Rating (Off State): Must match or exceed 800V to maintain circuit protection and performance
SCR Type: Must be Standard Recovery to ensure compatible switching characteristics
Package / Case: Must be TO-220-3 for mechanical and thermal compatibility with existing PCB layouts
Operating Temperature Range: Must support -40°C to 125°C operation
Gate Trigger Parameters: Vgt (Max) 1.5V and Igt (Max) 15mA ensure compatible gate drive requirements
On-State Voltage: Vtm (Max) 1.6V maintains consistent forward voltage drop performance

The TYN810RG from STMicroelectronics meets these substitution criteria with matching voltage ratings, gate trigger specifications, on-state voltage, SCR type, package configuration, and operating temperature range. The TYN810RG is an active product with ROHS3 compliance, providing a viable alternative for the obsolete CS220-12N.

Engineering Selection Recommendations

The TYN810RG is the designated manufacturer-recommended substitute for the CS220-12N. Selection of this substitute is supported by:

Product Status: The TYN810RG is an active product with ongoing manufacturer support, whereas the CS220-12N is obsolete
Electrical Compatibility: Matching voltage ratings (800V), gate trigger specifications (1.5V / 15mA), and on-state voltage (1.6V) ensure functional equivalence in circuit applications
Regulatory Compliance: The TYN810RG carries ROHS3 compliance certification, meeting current environmental and regulatory requirements
Thermal Performance: Identical operating temperature range (-40°C to 125°C) maintains thermal design compatibility
Package Compatibility: TO-220-3 through-hole packaging ensures direct mechanical and thermal interface compatibility with existing PCB designs

The TYN810RG current rating of 10A RMS is lower than the CS220-12N's 12A RMS rating. Circuit designs must verify that the 10A RMS rating is sufficient for the intended application current requirements.

Frequently Asked Questions (FAQ)

Q: Can the TYN810RG directly replace the CS220-12N in existing designs?

A: The TYN810RG is mechanically and electrically compatible with the CS220-12N for applications operating at or below 10A RMS. The TO-220-3 package provides identical pinout and thermal interface. Designs requiring the full 12A RMS capability of the original part must evaluate whether 10A RMS operation is acceptable.

Q: What are the key differences between these two SCR devices?

A: The primary differences are product status (obsolete vs. active), current rating (12A vs. 10A RMS), hold current specification (20mA vs. 30mA), and regulatory compliance (ROHS3 for the substitute). All critical voltage and gate trigger parameters are identical.

Q: Are the gate drive requirements the same for both parts?

A: Yes. Both the CS220-12N and TYN810RG require identical gate trigger voltage (1.5V maximum) and gate trigger current (15mA maximum), ensuring compatible gate drive circuitry.

Q: Does the TO-220-3 package provide the same thermal performance?

A: Both parts use the TO-220-3 through-hole package with identical mechanical dimensions and thermal interface characteristics. Thermal performance depends on PCB layout, heatsinking, and airflow conditions, which remain unchanged when substituting between these packages.

Q: Is the TYN810RG suitable for new product designs?

A: Yes. The TYN810RG is an active product with ROHS3 compliance, making it appropriate for new designs. The 10A RMS current rating must be verified against application requirements.
