Key Parameters

Substitute Part Grouping Explanation

Substitution of the NTHL080N120SC1 is determined by strict equivalence across the following critical electrical and mechanical parameters:

Mandatory Matching Parameters:

• Drain to Source Voltage (Vdss): 1200V
• FET Type: N-Channel
• Technology: SiCFET (Silicon Carbide)
• Package Type: TO-247-3 (Through Hole)
• Gate Charge (Qg) @ 20V: 56 nC
• Rds On (Max) @ 20A, 20V: 110 mOhm
• Vgs(th) (Max) @ 5mA: 4.3V
• Input Capacitance (Ciss) @ 800V: 1670 pF

Allowable Variation Parameters:

• Current - Continuous Drain (Id) @ 25°C: Equal or greater rating
• Power Dissipation (Max): Equal or greater rating
• Operating Temperature Range: Equal or extended range
• Product Status: Active status preferred for new designs; Obsolete acceptable for replacement applications

The NTHL080N120SC1A qualifies as a direct substitute based on matching all mandatory parameters while providing equal or superior performance in allowable variation categories.

Engineering Selection Recommendations

For Replacement Applications (Obsolete Part Substitution):

The NTHL080N120SC1A is suitable as a direct substitute for the obsolete NTHL080N120SC1 in existing designs. Both devices share identical electrical characteristics across all critical parameters including voltage rating, gate charge, on-resistance, and input capacitance. The NTHL080N120SC1A maintains ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment.

Design Considerations:

The NTHL080N120SC1A operates across an extended temperature range (-55°C to 175°C versus -55°C to 150°C), providing improved thermal margin for high-temperature applications. However, the continuous drain current rating is reduced from 44A to 31A, and maximum power dissipation is reduced from 348W to 178W. Applications requiring the full 44A continuous current or 348W power dissipation capability must verify that the NTHL080N120SC1A meets thermal and current requirements under actual operating conditions.

Compliance and Qualification:

The NTHL080N120SC1A carries AEC-Q101 automotive qualification, indicating suitability for automotive-grade applications. The original NTHL080N120SC1 does not specify automotive qualification. Selection should account for application-specific qualification requirements.

Frequently Asked Questions (FAQ)

Q: Can the NTHL080N120SC1A directly replace the NTHL080N120SC1 in all applications?

A: The NTHL080N120SC1A matches all mandatory electrical parameters and shares the same TO-247-3 package. However, applications requiring continuous drain current above 31A or power dissipation above 178W must be re-evaluated. The reduced current and power ratings may require thermal design modifications or circuit topology changes.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: The NTHL080N120SC1 is classified as Obsolete, indicating onsemi no longer manufactures or supports this part. The NTHL080N120SC1A is Active, meaning it is currently manufactured and supported. For new designs or long-term production, the Active part is preferred to ensure ongoing supply chain availability and manufacturer support.

Q: Are there any package or mounting differences between these parts?

A: Both the NTHL080N120SC1 and NTHL080N120SC1A use the TO-247-3 Through Hole package. No package or mounting modifications are required for substitution. Pin configuration and footprint are identical.

Q: How do the thermal operating ranges compare?

A: The NTHL080N120SC1 operates from -55°C to 150°C (TJ), while the NTHL080N120SC1A extends to -55°C to 175°C (TJ). The NTHL080N120SC1A provides 25°C additional high-temperature margin, beneficial for applications operating in elevated ambient or high-power conditions.

Q: What does AEC-Q101 qualification mean for the NTHL080N120SC1A?

A: AEC-Q101 is an automotive industry standard qualification for discrete semiconductors. The NTHL080N120SC1A meets this qualification, making it suitable for automotive applications requiring certified components. The original NTHL080N120SC1 does not specify this qualification.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the NTHL080N120SC1 and NTHL080N120SC1A are ROHS3 Compliant and REACH Unaffected, meeting environmental and regulatory requirements for commercial and industrial applications.
