CS220-16N Equivalent & Substitute Parts

Part Overview

The CS220-16N is an 800V 16A 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 CS220-16N 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 define gate drive requirements
On-State Voltage: Vtm (Max) 1.6V determines forward voltage drop characteristics

The TYN810RG from STMicroelectronics meets these substitution criteria with matching voltage ratings, gate trigger specifications, on-state voltage, and package configuration. However, the current rating differs: TYN810RG is rated at 10A RMS versus the CS220-16N's 16A RMS. This represents a derating and is acceptable only in applications where the circuit operates at or below 10A RMS.

Engineering Selection Recommendations

The TYN810RG is the designated manufacturer-recommended substitute for the CS220-16N. Selection of this substitute is supported by the following factors:

Product Status: TYN810RG is active and in production, ensuring long-term availability and supply chain stability, whereas CS220-16N is obsolete
Compliance: TYN810RG is RoHS3 compliant and REACH unaffected, meeting current regulatory requirements
Electrical Compatibility: Matching voltage ratings (800V), gate trigger specifications (1.5V / 15mA), and on-state voltage (1.6V) ensure functional equivalence in gate drive circuits
Thermal Compatibility: Identical operating temperature range (-40°C to 125°C) and TO-220-3 packaging maintain thermal management characteristics
Current Rating Consideration: The 10A RMS rating of TYN810RG represents a derating from the original 16A RMS specification. This substitute is suitable only for applications operating at or below 10A RMS continuous current

Frequently Asked Questions (FAQ)

Q: Can TYN810RG directly replace CS220-16N in all applications?

A: Direct replacement is possible only in applications where the circuit operates at or below 10A RMS. The TYN810RG is rated for 10A RMS maximum, compared to the CS220-16N's 16A RMS rating. If your application requires the full 16A RMS capability, this substitute is not suitable without circuit redesign.

Q: Are the gate trigger characteristics identical between these parts?

A: Yes. Both parts specify Vgt (Max) of 1.5V and Igt (Max) of 15mA, ensuring compatible gate drive requirements and control circuit design.

Q: Does the TO-220-3 package remain the same?

A: Yes. Both parts use TO-220-3 through-hole packaging, maintaining mechanical compatibility with existing PCB layouts and thermal management designs.

Q: What is the difference in hold current between these parts?

A: CS220-16N specifies Ih (Max) of 20mA, while TYN810RG specifies 30mA. The higher hold current of TYN810RG may affect circuit behavior in applications with marginal holding current margins.

Q: Is TYN810RG compliant with current regulations?

A: Yes. TYN810RG is RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards. CS220-16N, being obsolete, may not meet current compliance requirements for new designs.

Q: What is the non-repetitive surge current rating for TYN810RG?

A: TYN810RG is rated for 100A and 105A non-repetitive surge current at 50Hz and 60Hz respectively, providing robust protection against transient overcurrent conditions.
