IXFX520N075T2 Equivalent & Substitute Parts

Part Overview

The IXFX520N075T2 is an N-Channel MOSFET rated for 75V drain-to-source voltage with a continuous drain current of 520A at 25°C. This device is manufactured by IXYS using HiPerFET™ and TrenchT2™ technology in a PLUS247™-3 package. The part is currently active in production with 808 units in stock.

Substitute parts are identified when equivalent electrical performance can be achieved within the specified parameter ranges, particularly when the main part becomes unavailable or when alternative sourcing is required for supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for N-Channel MOSFETs is determined by matching the following critical parameters:

1. Voltage Rating (Vdss): Must equal or exceed 75V
2. Continuous Drain Current (Id): Must support the application's current requirements
3. On-State Resistance (Rds On): Lower values indicate better performance; substitutes with higher Rds On values result in increased power dissipation
4. Package Compatibility: Physical and electrical compatibility with PLUS247™-3 or equivalent TO-247-3 footprints
5. Operating Temperature Range: Must cover -55°C to 175°C
6. Compliance Status: RoHS3 compliance and REACH unaffected status required

The IRFP4368PBF meets the voltage rating and package requirements but operates at a reduced continuous drain current of 195A compared to the 520A rating of the IXFX520N075T2. This substitute is suitable for applications where the full 520A current capability is not required.

Engineering Selection Recommendations

IXFX520N075T2 (Primary Part)

The IXFX520N075T2 remains the preferred selection for applications requiring the full 520A continuous drain current capability. This part is active in production with adequate inventory (808 units in stock) and carries full RoHS3 compliance and REACH unaffected status.

IRFP4368PBF (Substitute Part)

The IRFP4368PBF is suitable as a substitute only for applications where the continuous drain current requirement does not exceed 195A. This part is discontinued at DiGi Electronics but maintains 26,494 units in stock through alternative channels. Both parts share identical voltage ratings (75V), operating temperature ranges (-55°C to 175°C), and compliance certifications (RoHS3, REACH unaffected).

The IRFP4368PBF exhibits lower on-state resistance (1.85 mOhm versus 2.2 mOhm) but reduced maximum power dissipation (520W versus 1250W). The TO-247AC package is mechanically compatible with TO-247-3 footprints for through-hole mounting applications.

Selection between these parts must be based on the application's actual current requirements. Substitution of the IRFP4368PBF for the IXFX520N075T2 in high-current applications (above 195A) will result in device thermal stress and potential failure.

Frequently Asked Questions (FAQ)

Q: Can the IRFP4368PBF directly replace the IXFX520N075T2 in all applications?

A: No. The IRFP4368PBF is rated for a maximum continuous drain current of 195A, compared to 520A for the IXFX520N075T2. Substitution is valid only when the application's continuous drain current requirement does not exceed 195A at 25°C.

Q: Are the package types compatible?

A: Both parts use TO-247-3 variant packages. The IXFX520N075T2 uses PLUS247™-3 packaging, while the IRFP4368PBF uses TO-247AC packaging. These packages are mechanically compatible for through-hole mounting on standard PCB layouts designed for TO-247-3 footprints.

Q: What is the impact of the different on-state resistance values?

A: The IRFP4368PBF has a lower on-state resistance (1.85 mOhm) compared to the IXFX520N075T2 (2.2 mOhm). At equivalent current levels, lower on-state resistance results in reduced power dissipation and improved thermal performance. However, this advantage applies only within the IRFP4368PBF's current rating of 195A.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both the IXFX520N075T2 and IRFP4368PBF are RoHS3 compliant, REACH unaffected, and carry Moisture Sensitivity Level 1 (unlimited). Both parts are suitable for applications with equivalent regulatory requirements.

Q: What is the difference in gate charge between these parts?

A: The IXFX520N075T2 has a gate charge of 545 nC at 10V, while the IRFP4368PBF has 570 nC at 10V. This 25 nC difference is negligible for most gate driver applications and does not constitute a limiting factor for substitution.

Q: Why is the IRFP4368PBF discontinued at DiGi Electronics?

A: Part discontinuation at specific distributors does not indicate product obsolescence. The IRFP4368PBF remains available through alternative inventory channels with 26,494 units in stock. Availability should be verified through secondary suppliers before committing to this substitute.

Q: How should I determine if my application can use the IRFP4368PBF?

A: Review your application's maximum continuous drain current requirement at 25°C. If this requirement is 195A or less, the IRFP4368PBF is electrically compatible. Verify that your PCB layout accommodates the TO-247AC package footprint and that thermal management is adequate for the 520W maximum power dissipation rating.
