IXFV26N60P N-Channel 600V 26A MOSFET Equivalent & Substitute Parts

Part Overview

The IXFV26N60P is an N-Channel 600V 26A power MOSFET manufactured by IXYS in the PolarHV™ series. This device is rated for 460W continuous power dissipation and features a PLUS220 package (TO-220-3 Short Tab) for through-hole mounting. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and production continuity. Substitute parts must maintain compatibility across critical electrical parameters including drain-source voltage, continuous drain current, on-resistance characteristics, and thermal performance while accommodating different package configurations.

Substitute Part Grouping Explanation

Substitution of the IXFV26N60P is determined by strict adherence to the following electrical and mechanical criteria:

Primary Substitution Criteria:

Drain-Source Voltage (Vdss): Must equal or exceed 600V
Continuous Drain Current (Id): Must equal or exceed 26A at 25°C
On-Resistance (Rds On): Must not exceed 270mOhm at specified gate voltage
Power Dissipation: Must support thermal requirements of the application
Gate Threshold Voltage: Must fall within compatible operating range
Operating Temperature: Must span -55°C to 150°C minimum
Mounting Type: Through-hole configuration required
Package Compatibility: TO-220-3 or equivalent footprint

Substitution Logic: Parts are grouped into two categories based on their ability to meet the primary criteria:

Direct Substitutes (Higher Current Rating): Parts exceeding 26A continuous drain current with Vdss ≥ 600V and Rds On ≤ 270mOhm. These provide enhanced current handling and thermal performance.
Functional Alternatives (Reduced Current Rating): Parts with continuous drain current below 26A but maintaining Vdss ≥ 600V and compatible Rds On characteristics. These are suitable for applications where the full 26A rating is not required.

Package variations (TO-220-3 standard vs. TO-247-3) are noted as they affect PCB layout and thermal management but do not prevent functional substitution in most applications.

Engineering Selection Recommendations

For Direct Current Replacement (≥26A Requirement):

The APT28F60B (Microsemi Corporation) is the only substitute part that meets or exceeds the 26A continuous drain current specification. This part delivers 30A at 25°C with superior on-resistance (250mOhm) and higher power dissipation capability (520W). The APT28F60B is classified as Active, ensuring long-term availability and supply chain stability. The TO-247-3 package provides enhanced thermal performance through larger lead geometry, though PCB layout modifications may be required. This part is suitable for direct functional replacement in applications requiring the full current rating of the original IXFV26N60P.

For Reduced Current Applications (<26A Requirement):

When application requirements permit continuous drain current below 26A, the following parts are recommended based on product status and compliance:

STP22NM60N (STMicroelectronics): Rated 16A continuous drain current with 220mOhm on-resistance and 125W power dissipation. Active product status with RoHS3 compliance. TO-220-3 package maintains original footprint compatibility.
FCP260N60E (Fairchild Semiconductor): Rated 15A continuous drain current with 260mOhm on-resistance and 156W power dissipation. Active product status. TO-220-3 package provides direct footprint compatibility.
SPP15N60C3XKSA1 (Infineon Technologies CoolMOS™): Rated 15A continuous drain current with 280mOhm on-resistance and 156W power dissipation. Active product status with RoHS3 compliance. Vdss rating of 650V provides additional voltage margin. TO-220-3 package.

Compliance and Availability:

All recommended active substitutes carry RoHS3 compliance and REACH Unaffected status, meeting modern regulatory requirements. Parts classified as Active or Last Time Buy ensure component availability for production planning. Obsolete alternatives (IPP60R280E6XKSA1) should be avoided for new designs despite electrical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the APT28F60B replace the IXFV26N60P in all applications?

A: The APT28F60B meets all electrical requirements for direct substitution, including Vdss (600V), continuous drain current (30A exceeds 26A), and on-resistance (250mOhm is superior to 270mOhm). The primary consideration is the package change from TO-220-3 Short Tab to TO-247-3, which requires PCB layout modification. Thermal performance is improved due to larger lead geometry. Electrical compatibility is confirmed.

Q: What is the difference between the IPP60R280C6XKSA1 and IPP60R280E6XKSA1?

A: Both parts are electrically identical with 600V Vdss, 13.8A continuous drain current, and 280mOhm on-resistance. The primary difference is product status: IPP60R280C6XKSA1 is Last Time Buy, while IPP60R280E6XKSA1 is Obsolete. For new designs, the C6 variant should be selected to ensure continued availability during the Last Time Buy window.

Q: Are the STMicroelectronics STP18N60M2 and STP18NM60N interchangeable?

A: Both parts share identical electrical specifications: 600V Vdss, 13A continuous drain current, and 280-285mOhm on-resistance. Both are Active products in TO-220-3 packages. The primary difference is the series designation (MDmesh™ II Plus vs. MDmesh™ II) and minor variations in gate charge (21.5 nC vs. 35 nC). They are functionally interchangeable for applications requiring 13A or less.

Q: Why does the SPP15N60C3XKSA1 have a higher Vdss rating (650V) than the original part (600V)?

A: The SPP15N60C3XKSA1 is rated for 650V Vdss, which exceeds the 600V requirement of the IXFV26N60P. This higher voltage rating provides additional safety margin in applications subject to voltage transients or overshoot conditions. The part remains fully compatible with 600V system designs and does not introduce incompatibility.

Q: Can I use a lower current-rated part if my application does not require 26A?

A: Yes. If your application requires continuous drain current below 26A, parts such as STP22NM60N (16A), FCP260N60E (15A), or SPP15N60C3XKSA1 (15A) are suitable substitutes. The critical requirement is that the selected part's continuous drain current rating must equal or exceed the actual application current demand. Verify your circuit's maximum sustained current before selecting a lower-rated alternative.

Q: What are the thermal implications of switching from IXFV26N60P to APT28F60B?

A: The APT28F60B provides superior thermal performance through higher power dissipation capability (520W vs. 460W) and lower on-resistance (250mOhm vs. 270mOhm). The TO-247-3 package features larger lead geometry compared to TO-220-3, improving heat transfer to the PCB and heatsink. These characteristics reduce junction temperature under identical current and ambient conditions. Thermal design should be re-evaluated to take advantage of improved performance.

Q: Are all substitute parts RoHS compliant?

A: All recommended Active and Last Time Buy parts carry RoHS3 compliance certification. The obsolete IXFV26N60P and IPP60R280E6XKSA1 do not have RoHS3 compliance documented in the provided specifications. For applications requiring RoHS compliance, select only parts with explicit RoHS3 status.

Q: What is the significance of the PLUS220 package designation on the original part?

A: PLUS220 is IXYS's proprietary designation for a TO-220-3 Short Tab package. This package is functionally equivalent to standard TO-220-3 packages used by other manufacturers. Substitute parts in standard TO-220-3 packages maintain footprint compatibility. The TO-247-3 package (APT28F60B) is physically larger and requires PCB layout modification but provides improved thermal performance.
