IXTP140N12T2 Equivalent & Substitute Parts

Part Overview

The IXTP140N12T2 is an N-Channel MOSFET manufactured by IXYS, designed for high-current switching applications. This device operates at 120V drain-to-source voltage with a continuous drain current rating of 140A at 25°C. The component is housed in a TO-220-3 through-hole package and belongs to the TrenchT2™ series. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter ranges, allowing for component interchangeability in circuit designs.

Substitute Part Grouping Explanation

Substitution eligibility for the IXTP140N12T2 is determined by the following criteria:

Electrical Compatibility Requirements:

• Drain-to-Source Voltage (Vdss) must equal or exceed 120V
• Continuous Drain Current (Id) must equal or exceed 140A at 25°C
• RDS(on) characteristics must support equivalent on-state performance
• Gate threshold voltage must fall within compatible operating ranges
• Operating temperature range must encompass -55°C to 175°C

Mechanical Compatibility Requirements:

• Package type must be TO-220-3 through-hole configuration
• Mounting type must be through-hole
• Pin configuration must match TO-220-3 standard

Compliance Requirements:

• RoHS3 compliance required
• REACH Unaffected status required
• Active product status required

The FDP083N15A-F102 qualifies as a substitute based on these criteria, with specific trade-offs in current rating and voltage rating that remain within acceptable substitution parameters.

Engineering Selection Recommendations

IXTP140N12T2 (Primary Selection)

The IXTP140N12T2 is the specified component for applications requiring 140A continuous drain current at 120V. This part maintains Active product status with full RoHS3 compliance and MSL 1 rating. The TrenchT2™ series technology provides optimized performance for high-current switching applications. Selection of this part is appropriate when the full 140A current rating and 577W power dissipation capability are required within the design specification.

FDP083N15A-F102 (Substitute Selection)

The FDP083N15A-F102 qualifies as a substitute when circuit requirements permit operation at reduced continuous drain current (83A versus 140A) and lower power dissipation (294W versus 577W). This onsemi PowerTrench® device offers higher voltage rating (150V versus 120V), providing additional voltage margin in applications where the 120V specification is not a limiting factor. The substitute maintains identical operating temperature range, TO-220-3 package configuration, and compliance certifications. Gate charge is significantly lower (84nC versus 174nC), resulting in faster switching characteristics. This substitute is appropriate for applications where current requirements do not exceed 83A and where the reduced power dissipation is acceptable.

Both parts maintain Active product status and full regulatory compliance, ensuring long-term availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can the FDP083N15A-F102 directly replace the IXTP140N12T2 in all applications?

A: The FDP083N15A-F102 can replace the IXTP140N12T2 only in applications where the continuous drain current requirement does not exceed 83A. The substitute part has a lower current rating (83A versus 140A) and lower power dissipation capability (294W versus 577W). Circuit designs operating at or near the 140A specification of the original part cannot use this substitute without redesign.

Q: What are the voltage compatibility considerations between these parts?

A: The IXTP140N12T2 operates at 120V Vdss, while the FDP083N15A-F102 operates at 150V Vdss. The substitute part has a higher voltage rating, making it suitable for circuits designed for 120V operation. No voltage derating is required when substituting the FDP083N15A-F102 into a 120V circuit design.

Q: Are the package configurations identical?

A: Both parts use the TO-220-3 through-hole package with identical pin configuration and mounting requirements. No PCB layout modifications are necessary for mechanical compatibility.

Q: What is the significance of the gate charge difference?

A: The FDP083N15A-F102 has lower gate charge (84nC versus 174nC), resulting in faster switching transitions and reduced gate drive power requirements. This characteristic may improve overall circuit efficiency but does not affect substitution eligibility based on the specified parameters.

Q: Do both parts meet the same compliance standards?

A: Both the IXTP140N12T2 and FDP083N15A-F102 are RoHS3 compliant, REACH Unaffected, and maintain Active product status. Both parts are suitable for applications with identical regulatory requirements.

Q: What is the primary limitation when using the FDP083N15A-F102 as a substitute?

A: The primary limitation is the reduced continuous drain current rating (83A versus 140A). Applications requiring sustained current operation above 83A must use the original IXTP140N12T2 or identify alternative parts with higher current ratings.
