Key Parameters

Substitute Part Grouping Explanation

Substitution of the TMA84S-L is determined by the following critical parameters:

• Voltage Rating (Off-State): The substitute must meet or exceed 400V off-state voltage capability
• Current Rating (On-State): The substitute must support 8A RMS on-state current or higher
• Gate Trigger Characteristics: Vgt and Igt parameters must be compatible with existing gate drive circuitry
• Package Type: Physical form factor must accommodate TO-220-3 through-hole mounting
• Compliance & Certifications: RoHS compliance and MSL rating must be maintained
• Product Status: Active or current production status ensures long-term availability

The TMG3C80F5 qualifies as a manufacturer-recommended substitute based on these criteria.

Parameter Comparison

Engineering Selection Recommendations

The TMG3C80F5 is the manufacturer-recommended substitute for the obsolete TMA84S-L. Both components are manufactured by Sanken Electric USA Inc. and maintain identical RoHS compliance and MSL Level 1 ratings. The TMG3C80F5 provides equivalent 8A on-state current capability with an elevated 800V off-state voltage rating, offering enhanced voltage margin for the same current specification. Active product status ensures availability for current and future production requirements.

Frequently Asked Questions (FAQ)

Q: Can the TMG3C80F5 directly replace the TMA84S-L in existing designs?

A: The TMG3C80F5 meets the core electrical requirements: 8A on-state current and RoHS compliance. The higher 800V off-state voltage provides additional design margin. Verification of gate trigger characteristics and circuit-level compatibility with existing gate drive circuitry is necessary before implementation.

Q: What is the primary reason for substitution?

A: The TMA84S-L is classified as obsolete. The TMG3C80F5 is an active product from the same manufacturer, ensuring long-term supply availability and production continuity.

Q: Are there package differences between these parts?

A: Package information for the TMG3C80F5 was not provided in the available data. Physical form factor compatibility must be confirmed before design implementation.

Q: Do both parts carry the same compliance certifications?

A: Both the TMA84S-L and TMG3C80F5 are RoHS compliant with MSL Level 1 rating, indicating no moisture sensitivity constraints during standard storage and handling conditions.
