IXFX30N50 Equivalent & Substitute Parts

Part Overview

The IXFX30N50 is an N-channel MOSFET in PLUS247 packaging manufactured by IXYS. This device is classified as Obsolete and is no longer in active production. The part was designed for high-voltage switching applications requiring 500V drain-to-source capability with 30A continuous drain current rating.

Due to its obsolete status, sourcing original IXFX30N50 units is subject to inventory depletion. Identifying qualified substitute components with equivalent electrical and mechanical characteristics is necessary to maintain design continuity and ensure long-term supply chain reliability for applications currently utilizing this device.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete IXFX30N50 is determined by alignment of the following critical electrical and mechanical parameters:

Electrical Criteria:

• FET Type: N-Channel
• Technology: MOSFET (Metal Oxide)
• Drain-to-Source Voltage (Vdss): 500V
• Continuous Drain Current (Id @ 25°C): 30A (Tc)
• Gate Drive Voltage: 10V
• Moisture Sensitivity Level: 1 (Unlimited)

Mechanical Criteria:

• Mounting Type: Through Hole
• Package Type: TO-247 variant

The primary substitute identified is IXFH30N50P, which is manufactured by IXYS and maintains active product status. This device shares the identical electrical specifications (500V, 30A) and is housed in the TO-247AD package, a direct mechanical equivalent to the original PLUS247 packaging. The IXFH30N50P is part of the HiPerFET™ series and carries full RoHS3 compliance and REACH Unaffected status.

Additional cross-reference substitutes (STW19NM50N, APT30F50B, IRFP31N50LPBF, APT5017BVRG, STW26NM60N) are listed in the IXFH30N50P documentation but require individual verification against specific application requirements due to potential variations in secondary electrical parameters not provided in this reference.

Engineering Selection Recommendations

Primary Substitute: IXFH30N50P

The IXFH30N50P is the recommended direct substitute for the obsolete IXFX30N50. Selection is based on the following factors:

1. Manufacturer Continuity: Both devices are manufactured by IXYS, ensuring design heritage and process consistency.

2. Electrical Equivalence: The IXFH30N50P maintains identical voltage (500V) and current (30A) ratings, with matching gate drive voltage (10V) and thermal characteristics (460W power dissipation).

3. Package Compatibility: The TO-247AD package is mechanically compatible with the original PLUS247 packaging for through-hole mounting applications. Pin configuration and thermal interface remain consistent.

4. Compliance Status: The IXFH30N50P carries active product status with full RoHS3 compliance and REACH Unaffected designation, ensuring regulatory alignment for new designs and long-term availability.

5. Moisture Sensitivity: Both devices share MSL 1 (Unlimited) classification, indicating no moisture-related handling restrictions.

6. Inventory Availability: The IXFH30N50P maintains active inventory (1864 units in stock) compared to the depleting IXFX30N50 stock (715 units), providing superior supply chain security.

Frequently Asked Questions (FAQ)

Q: Can the IXFH30N50P be used as a direct replacement for the IXFX30N50 in existing designs?

A: Yes. The IXFH30N50P is electrically and mechanically equivalent to the IXFX30N50. Both devices share identical voltage (500V), current (30A), and gate drive (10V) specifications. The TO-247AD package is compatible with the original PLUS247 through-hole mounting configuration.

Q: What is the difference between PLUS247 and TO-247AD packaging?

A: PLUS247 is IXYS's proprietary designation for a through-hole package variant. TO-247AD is the industry-standard nomenclature for the same physical package form factor. Both provide identical pin spacing, mounting footprint, and thermal interface characteristics.

Q: Why is the IXFX30N50 classified as obsolete?

A: The IXFX30N50 has been discontinued by IXYS and is no longer manufactured. The IXFH30N50P represents the current-generation equivalent within the IXYS product portfolio.

Q: Are there any secondary electrical parameter differences between the IXFX30N50 and IXFH30N50P?

A: The IXFH30N50P provides complete electrical specifications including Rds On (200 mOhm @ 15A, 10V), gate charge (70 nC @ 10V), and input capacitance (4150 pF @ 25V). The original IXFX30N50 datasheet does not provide these detailed parameters in the available documentation. Applications requiring specific secondary parameter values should reference the IXFH30N50P datasheet for confirmation.

Q: What is the moisture sensitivity level for both devices?

A: Both the IXFX30N50 and IXFH30N50P carry MSL 1 (Unlimited) classification. This indicates no moisture-related handling, storage, or reflow restrictions apply to either device.

Q: Is the IXFH30N50P RoHS compliant?

A: Yes. The IXFH30N50P is RoHS3 compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic components in most jurisdictions.

Q: What other substitutes are listed for the IXFH30N50P?

A: The IXFH30N50P documentation references STW19NM50N, APT30F50B, IRFP31N50LPBF, APT5017BVRG, and STW26NM60N as cross-reference options. These devices are manufactured by different suppliers and may have variations in secondary electrical parameters, package form factors, or thermal characteristics. Each requires individual evaluation against specific application requirements.

Q: Can I use the IXFH30N50P in new designs?

A: Yes. The IXFH30N50P is an active product with full manufacturer support, documentation, and long-term availability. It is suitable for both replacement of obsolete IXFX30N50 units and incorporation into new designs requiring 500V, 30A N-channel MOSFET functionality.
