S8006RTP Equivalent & Substitute Parts

Part Overview

The S8006RTP is a Silicon Controlled Rectifier (SCR) manufactured by Littelfuse, rated for 800V off-state voltage with 6A RMS on-state current capability. This thyristor is designed for standard recovery applications in Through Hole TO-220AB-R packaging. The part is currently Active in product status with full RoHS3 compliance and unlimited moisture sensitivity rating. Alternative components may be required due to inventory constraints, application-specific current requirements, or supply chain considerations.

Key Parameters

Substitute Part Grouping Explanation

The TYN810RG from STMicroelectronics qualifies as a parametric equivalent based on the following criteria:

Matching Parameters:

• Voltage - Off State: 800V (identical)
• Voltage - Gate Trigger (Vgt) Max: 1.5V (identical)
• Current - Gate Trigger (Igt) Max: 15mA (identical)
• Voltage - On State (Vtm) Max: 1.6V (identical)
• Current - Hold (Ih) Max: 30mA (identical)
• Operating Temperature Range: -40°C to 125°C (identical)
• Package / Case: TO-220-3 (identical)
• SCR Type: Standard Recovery (identical)
• RoHS3 Compliance: Yes (identical)
• Moisture Sensitivity Level: 1 Unlimited (identical)

Distinguishing Parameter:

• Current - On State (It RMS) Max: 10A (versus 6A for S8006RTP)

The TYN810RG provides higher on-state current capacity while maintaining all other electrical and mechanical specifications. This substitution is valid for applications where the 6A rating is not a limiting factor and higher current capability is acceptable.

Parameter Comparison

Engineering Selection Recommendations

Both the S8006RTP and TYN810RG are Active products with full RoHS3 compliance and REACH unaffected status. Selection between these components should be based on application current requirements:

• S8006RTP is appropriate for applications requiring 6A RMS maximum on-state current with 800V blocking capability.
• TYN810RG is appropriate for applications requiring up to 10A RMS on-state current with identical 800V blocking capability and gate trigger characteristics.

Both components share identical gate trigger thresholds, hold current specifications, and thermal operating ranges, ensuring functional compatibility in circuit designs. The TO-220-3 package is identical for both parts, allowing direct mechanical substitution. Selection should confirm that the application current demand does not exceed the chosen component's rating and that thermal management is adequate for the intended duty cycle.

Frequently Asked Questions (FAQ)

Q: Can TYN810RG directly replace S8006RTP in existing designs?

A: Direct mechanical and electrical substitution is possible. The TYN810RG maintains identical gate trigger voltage (1.5V max), gate trigger current (15mA max), on-state voltage drop (1.6V max), and operating temperature range (-40°C to 125°C). Both use TO-220-3 packaging. The primary difference is higher on-state current rating (10A RMS versus 6A RMS), which does not create compatibility issues if the application current remains within the original 6A specification.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by: off-state voltage rating (800V), gate trigger characteristics (Vgt 1.5V max, Igt 15mA max), on-state voltage drop (Vtm 1.6V max), hold current (30mA max), SCR type (Standard Recovery), package type (TO-220-3), and compliance certifications (RoHS3, REACH unaffected). These parameters must match or exceed the original specification.

Q: Are there thermal or mounting considerations when substituting these parts?

A: Both components use identical TO-220-3 Through Hole packaging and share the same -40°C to 125°C operating temperature range. Thermal management requirements depend on application duty cycle and current loading. Existing heatsink and PCB thermal design for the S8006RTP remain valid for the TYN810RG.

Q: What is the significance of the higher current rating in TYN810RG?

A: The TYN810RG supports 10A RMS on-state current compared to 6A RMS for the S8006RTP. This higher rating provides design margin for applications operating near the original 6A limit and allows use in higher-current applications. It does not negatively impact applications designed for lower current levels.

Q: Are both parts available with the same compliance certifications?

A: Yes. Both S8006RTP and TYN810RG are RoHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings. Compliance documentation is equivalent for both components.
