Engineering Selection Recommendations

Primary Part: IXFH74N20P

The IXFH74N20P is the preferred selection when maximum continuous drain current (74A) and power dissipation capability (480W) are required within the 200V voltage class. This part is Active in product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). The HiPerFET™ series designation indicates optimized performance characteristics for high-efficiency switching applications.

Substitute Parts: IRFP260MPBF and IRFP260NPBF

Both IRFP260 variants are functionally equivalent substitutes for applications where the continuous drain current requirement does not exceed 50A. These parts are Active in product status with identical RoHS3 compliance and MSL 1 ratings. The HEXFET® series from Infineon Technologies provides equivalent voltage and temperature specifications.

Selection Criteria:

Use IXFH74N20P when continuous drain current exceeds 50A or when power dissipation requirements approach or exceed 300W
Use IRFP260MPBF or IRFP260NPBF when continuous drain current is limited to 50A or less and power dissipation does not exceed 300W
All three parts share identical voltage ratings (200V Vdss), gate drive voltage (10V), and operating temperature range (-55°C to 175°C)
All three parts are RoHS3 compliant and carry Active product status
TO-247AD and TO-247AC packages are mechanically and electrically compatible for through-hole mounting applications

Frequently Asked Questions (FAQ)

Q: Can IRFP260MPBF or IRFP260NPBF be used as direct replacements for IXFH74N20P?

A: IRFP260MPBF and IRFP260NPBF are functionally equivalent substitutes for applications where the continuous drain current requirement does not exceed 50A. Both parts share identical voltage ratings (200V), gate drive voltage (10V), operating temperature range (-55°C to 175°C), and compliance certifications (RoHS3). However, the IXFH74N20P provides higher continuous drain current (74A versus 50A) and greater power dissipation capability (480W versus 300W). Substitution is valid only when circuit design does not require these higher current or power ratings.

Q: Are TO-247AD and TO-247AC packages interchangeable?

A: TO-247AD and TO-247AC packages are both TO-247-3 through-hole packages with identical pin configurations and mechanical compatibility. Both packages support the same mounting and thermal management approaches. The packages are interchangeable for circuit board layout and assembly purposes.

Q: What are the key electrical differences between IXFH74N20P and the IRFP260 variants?

A: The primary electrical differences are continuous drain current and power dissipation. IXFH74N20P is rated for 74A continuous drain current and 480W power dissipation, while IRFP260MPBF and IRFP260NPBF are each rated for 50A continuous drain current and 300W power dissipation. Gate charge (Qg) is higher in the IRFP260 variants (234 nC versus 107 nC), and input capacitance (Ciss) is also higher (4057 pF versus 3300 pF). On-resistance (Rds On) specifications differ due to different current measurement points: IXFH74N20P at 37A versus IRFP260 variants at 28A.

Q: Are both IRFP260MPBF and IRFP260NPBF identical in electrical performance?

A: Yes. IRFP260MPBF and IRFP260NPBF share identical electrical specifications, voltage ratings, current ratings, gate charge, input capacitance, power dissipation, and operating temperature range. Both are manufactured by Infineon Technologies under the HEXFET® series and are supplied in TO-247AC packages. The parts are functionally equivalent.

Q: What compliance certifications apply to all three parts?

A: All three parts (IXFH74N20P, IRFP260MPBF, and IRFP260NPBF) are RoHS3 compliant, carry REACH Unaffected status, and are classified under ECCN EAR99. All three parts have unlimited moisture sensitivity rating (MSL 1). All three parts are currently Active in product status.

Q: Can IXFH74N20P be substituted with IRFP260 variants in high-current applications?

A: No. IRFP260MPBF and IRFP260NPBF are rated for maximum continuous drain current of 50A, while IXFH74N20P is rated for 74A. Substitution in applications requiring continuous drain current above 50A would result in device operation beyond rated specifications and is not permitted.
