IXFX140N30P Equivalent & Substitute Parts

Part Overview

The IXFX140N30P is an N-Channel MOSFET manufactured by IXYS, rated for 300V drain-to-source voltage and 140A continuous drain current at 25°C. This device is part of the HiPerFET™ series and is housed in a PLUS247™-3 package for through-hole mounting applications. The part is currently Active in product status with 86,866 pieces in stock inventory.

Substitute parts are identified when equivalent electrical performance can be achieved within the specified parameter ranges, allowing for component interchangeability in circuit designs where the main part may be unavailable or where alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IXFX140N30P is determined by the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

• Drain to Source Voltage (Vdss): Must equal or exceed 300V
• Continuous Drain Current (Id): Must equal or exceed 140A at 25°C
• Drive Voltage: Must support 10V gate drive
• Package Type: Must be compatible with TO-247-3 through-hole mounting
• RoHS Compliance: Must maintain ROHS3 compliance status

Secondary Compatibility Factors:

• Gate Charge (Qg): Lower values preferred for reduced switching losses
• On-State Resistance (Rds On): Lower values preferred for reduced conduction losses
• Operating Temperature Range: Must accommodate application requirements
• Moisture Sensitivity Level: MSL 1 (Unlimited) preferred for handling flexibility

The substitute parts identified below meet the primary substitution criteria within the allowed parameter ranges for this product category.

Parameter Comparison

Engineering Selection Recommendations

IXFX140N30P (Primary Part)

The IXFX140N30P remains the primary selection for new designs. This part is Active in product status with substantial inventory availability (86,866 pieces). It delivers the highest continuous drain current rating (140A) and power dissipation capability (1040W) among the available options. The part maintains ROHS3 compliance and operates across the full temperature range of -55°C to 150°C.

IRFP4868PBF (Partial Substitute)

The IRFP4868PBF is electrically compatible at the 300V Vdss rating and supports 10V gate drive. However, this part is designated "Not For New Designs" by the manufacturer, limiting its suitability for ongoing development. The continuous drain current rating (70A) is 50% of the main part, and power dissipation (517W) is approximately 50% of the IXFX140N30P. This part is suitable only for legacy system maintenance or where current requirements do not exceed 70A. ROHS3 compliance and extended temperature range (-55°C to 175°C) are maintained.

IRFP4332PBF (Limited Substitute)

The IRFP4332PBF operates at a reduced Vdss rating of 250V, which is below the 300V specification of the main part. The continuous drain current (57A) and power dissipation (360W) are significantly lower than the IXFX140N30P. This part is suitable only for applications where the 250V voltage rating is acceptable and current requirements do not exceed 57A. The part is Active in product status and maintains ROHS3 compliance with an extended operating temperature range (-40°C to 175°C).

Frequently Asked Questions (FAQ)

Q: Can IRFP4868PBF be used as a direct replacement for IXFX140N30P?

A: The IRFP4868PBF shares the same 300V Vdss rating and 10V gate drive specification. However, the continuous drain current is rated at 70A compared to 140A for the IXFX140N30P. Substitution is only valid for applications where the maximum required drain current does not exceed 70A. Additionally, IRFP4868PBF is designated "Not For New Designs," making it unsuitable for new product development.

Q: What is the voltage limitation of IRFP4332PBF?

A: The IRFP4332PBF is rated for 250V drain-to-source voltage, which is 50V below the 300V rating of the IXFX140N30P. This part cannot be substituted in circuits requiring the full 300V voltage capability. Substitution is limited to applications where the maximum drain-to-source voltage does not exceed 250V.

Q: Are all substitute parts compatible with TO-247-3 through-hole mounting?

A: Yes. The IXFX140N30P uses a PLUS247™-3 package, and both substitute parts (IRFP4868PBF and IRFP4332PBF) use TO-247AC packages, which are mechanically compatible with TO-247-3 through-hole mounting. Pin configurations and lead spacing are equivalent for direct board-level substitution.

Q: Do all parts maintain RoHS3 compliance?

A: Yes. The IXFX140N30P, IRFP4868PBF, and IRFP4332PBF are all ROHS3 compliant. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for all parts, providing equivalent handling flexibility.

Q: What are the temperature operating range differences?

A: The IXFX140N30P operates from -55°C to 150°C (TJ). The IRFP4868PBF extends to 175°C, and the IRFP4332PBF operates from -40°C to 175°C. Applications requiring operation below -40°C must use the IXFX140N30P or IRFP4868PBF.

Q: How do gate charge specifications affect substitution?

A: Gate charge (Qg) affects switching speed and driver circuit requirements. The IXFX140N30P has 185 nC, IRFP4868PBF has 270 nC, and IRFP4332PBF has 150 nC. Higher gate charge requires more driver current and increases switching losses. Substitution is valid from a functional standpoint, but circuit performance characteristics will differ.

Q: What is the significance of "Not For New Designs" status for IRFP4868PBF?

A: This designation indicates that the manufacturer is not recommending this part for new product development. While the part remains available and functional, it may have limited long-term availability or may be subject to discontinuation. For new designs, the IXFX140N30P or IRFP4332PBF (where voltage requirements permit) are preferred selections.
