Part Overview

The IXFH76N07-12 is an N-Channel MOSFET manufactured by IXYS, rated for 70V drain-to-source voltage with 76A continuous drain current at 25°C. This device is packaged in TO-247AD (IXFH) through-hole configuration and is part of the HiPerFET™ series. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new design alternatives. Substitute parts must maintain functional compatibility within the specified electrical and mechanical parameters while accounting for differences in voltage rating, current capacity, and thermal characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IXFH76N07-12 is determined by the following critical parameters:

Electrical Compatibility Criteria:

• FET Type: N-Channel topology must be maintained
• Drain to Source Voltage (Vdss): Substitute parts must equal or exceed 70V
• Continuous Drain Current (Id): Substitute parts must equal or exceed 76A at 25°C
• Rds On (Max): On-resistance at specified gate voltage and current
• Gate Charge (Qg): Total gate charge affects switching speed and drive requirements
• Operating Temperature Range: Must support -55°C to 175°C (TJ)

Mechanical Compatibility Criteria:

• Mounting Type: Through Hole required
• Package / Case: TO-247-3 form factor required
• Supplier Device Package: TO-247AD (IXFH) or equivalent TO-247 variants

Compliance Criteria:

• RoHS3 Compliance required
• REACH Unaffected status required

Substitute parts are grouped based on whether they maintain these core parameters while potentially offering improved voltage ratings, current capacity, or thermal performance. Parts that exceed the original specifications in voltage or current rating remain valid substitutes provided they operate within the same package footprint and thermal envelope.

Parameter Comparison

Engineering Selection Recommendations

IXFH76N15T2 (IXYS)

The IXFH76N15T2 is an active product from IXYS within the HiPerFET™ series with TrenchT2™ technology. This part maintains the 76A continuous drain current specification of the original IXFH76N07-12 while providing a higher 150V drain-to-source voltage rating. The part is ROHS3 compliant and operates across the same temperature range (-55°C to 175°C). The TO-247-3 package footprint is compatible with the original design. Gate charge is reduced to 97 nC, improving switching performance. On-resistance increases to 22 mOhm due to the higher voltage rating. This part is suitable for applications requiring higher voltage headroom while maintaining current capacity.

IXFH110N10P (IXYS)

The IXFH110N10P is an active product from IXYS within the HiPerFET™ series with Polar technology. This part provides 110A continuous drain current at 100V drain-to-source voltage, exceeding both the current and voltage specifications of the original part. The TO-247AD package is identical to the original. Power dissipation capability is increased to 480W. Gate charge is reduced to 110 nC. This part is suitable for applications requiring higher current capacity and voltage margin with improved thermal performance.

IRFP054NPBF (Infineon Technologies)

The IRFP054NPBF is from Infineon Technologies within the HEXFET® series and carries a "Not For New Designs" product status. This part provides 81A continuous drain current at 55V drain-to-source voltage. The voltage rating is lower than the original IXFH76N07-12 (55V versus 70V), making this part suitable only for applications with lower voltage requirements. On-resistance is 12 mOhm, matching the original specification. Power dissipation is limited to 170W. The TO-247AC package is mechanically compatible with TO-247-3 footprint. This part is not recommended for new designs due to its product status classification.

Frequently Asked Questions (FAQ)

Q: Can the IXFH76N15T2 directly replace the IXFH76N07-12 in existing designs?

A: The IXFH76N15T2 is mechanically compatible (TO-247-3 package) and maintains the 76A continuous drain current. However, the higher 150V drain-to-source voltage rating and increased on-resistance (22 mOhm versus 12 mOhm) must be evaluated within the specific circuit application. The part is electrically suitable for applications operating at or below 70V, with the higher voltage rating providing additional safety margin.

Q: What is the primary difference between IXFH76N15T2 and IXFH110N10P?

A: The IXFH76N15T2 maintains the original 76A current rating with a 150V voltage rating, while the IXFH110N10P increases current capacity to 110A at 100V. The IXFH110N10P is selected when higher current handling is required. The IXFH76N15T2 is selected when higher voltage rating is the priority while maintaining original current specifications.

Q: Why is the IRFP054NPBF listed as a substitute if it has a lower voltage rating?

A: The IRFP054NPBF is included as a substitute for applications where the 70V voltage requirement can be reduced to 55V. The part provides equivalent on-resistance (12 mOhm) and comparable current capacity (81A). This part is suitable only for lower-voltage circuit variants and is not recommended for new designs due to its product status.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (IXFH76N15T2, IXFH110N10P, and IRFP054NPBF) are ROHS3 compliant and REACH unaffected, matching the compliance status of the original IXFH76N07-12.

Q: What is the impact of gate charge differences on circuit design?

A: Gate charge (Qg) affects the gate drive circuit requirements. The original IXFH76N07-12 has 240 nC gate charge. The IXFH76N15T2 reduces this to 97 nC, and the IXFH110N10P to 110 nC. Lower gate charge reduces switching losses and simplifies gate drive design. Higher gate charge (IRFP054NPBF at 130 nC) requires more robust gate drive capability.

Q: Can these parts be used interchangeably in PCB layouts?

A: All substitute parts use the TO-247-3 package footprint, making them mechanically interchangeable on standard TO-247 PCB layouts. However, thermal management considerations differ due to varying power dissipation ratings (350W to 480W). Thermal pad design and heatsink requirements should be verified for each specific part selection.

Q: What is the significance of the "Active" versus "Obsolete" product status?

A: The original IXFH76N07-12 is classified as obsolete, indicating it is no longer in production and inventory is limited. The IXFH76N15T2 and IXFH110N10P are active products with ongoing manufacturing and availability. The IRFP054NPBF is classified as "Not For New Designs," indicating it is in limited production and should not be selected for new circuit development.
