IXTP220N055T N-Channel MOSFET Equivalent & Substitute Parts

Part Overview

The IXTP220N055T is an N-Channel MOSFET manufactured by IXYS, rated for 55V drain-to-source voltage with 220A continuous drain current at 25°C. This device is packaged in TO-220-3 through-hole configuration and is part of the TrenchMV™ series. The part is currently listed as obsolete, making identification of equivalent and substitute components necessary for ongoing design support and production continuity. Substitute parts must maintain electrical compatibility within the specified voltage and current ratings while accommodating the through-hole TO-220-3 package format.

Substitute Part Grouping Explanation

Substitution eligibility for the IXTP220N055T is determined by the following critical parameters:

Voltage Rating Compatibility: Substitute parts must have a Vdss rating equal to or greater than 55V. Parts with higher voltage ratings (60V, 75V) are acceptable as they provide equivalent or superior voltage withstand capability.

Current Rating Compatibility: Substitute parts must have a continuous drain current (Id) rating equal to or greater than 220A at 25°C. This ensures the substitute can handle the same or greater current load without thermal stress.

Package Compatibility: All substitute parts must use the TO-220-3 through-hole package format to ensure mechanical and thermal compatibility with existing PCB layouts and heatsinking arrangements.

Operating Temperature Range: Substitute parts must support the full operating temperature range of -55°C to 175°C to maintain functional equivalence across all environmental conditions.

Gate Drive Voltage: Substitute parts must be compatible with 10V gate drive voltage, the standard drive voltage specified for the main part.

Parts meeting these criteria are classified as direct substitutes. Parts with higher current ratings or lower on-state resistance values provide performance enhancements while maintaining full backward compatibility.

Engineering Selection Recommendations

Primary Substitute - Full Electrical Equivalence:

The IXTP260N055T2 is the recommended primary substitute. This part maintains the same 55V voltage rating as the original IXTP220N055T while providing enhanced performance characteristics. The IXTP260N055T2 delivers 260A continuous drain current, exceeding the 220A requirement, and features improved on-state resistance of 3.3mOhm compared to 4.0mOhm. Gate charge is reduced to 140nC, improving switching efficiency. The part is manufactured by IXYS using the TrenchT2™ technology platform and holds Active product status with RoHS3 compliance certification. This part is suitable for direct replacement in existing designs without circuit modification.

Secondary Substitutes - Higher Voltage Rating:

The IRFB3207PBF and IRFB3207ZPBF are Infineon HEXFET® devices with 75V voltage ratings. Both parts are manufactured by Infineon and hold Active product status with RoHS3 compliance. The IRFB3207PBF provides 170A continuous current with 4.5mOhm on-state resistance. The IRFB3207ZPBF provides 120A continuous current with 4.1mOhm on-state resistance. These parts are suitable for applications where higher voltage margin is required, though they exceed the original voltage specification.

Alternative Substitutes - Reduced Current Rating:

The IRFB3306PBF is a 60V, 120A device with 4.2mOhm on-state resistance and Active product status. The CSD18532KCS is a Texas Instruments NexFET™ device rated for 60V and 100A with 4.2mOhm on-state resistance and Active product status. The IPP040N06N3GXKSA1 is an Infineon OptiMOS™ device rated for 60V and 90A; however, this part carries "Not For New Designs" status and should not be selected for new production. The STP130N6F7 is an STMicroelectronics STripFET™ F7 device rated for 60V and 80A with 5.0mOhm on-state resistance and Active product status.

These alternatives are suitable only for applications where the reduced current rating (below 220A) is acceptable. All recommended active substitutes carry RoHS3 compliance certification and support the full -55°C to 175°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can the IXTP260N055T2 be used as a direct replacement for the IXTP220N055T?

A: Yes. The IXTP260N055T2 maintains the same 55V voltage rating and TO-220-3 package format. The higher current rating (260A vs. 220A) and improved on-state resistance (3.3mOhm vs. 4.0mOhm) provide enhanced performance without requiring circuit modifications. Both parts support 10V gate drive voltage and the full -55°C to 175°C operating temperature range.

Q: Why do some substitute parts have higher voltage ratings (60V or 75V)?

A: Higher voltage-rated devices provide superior voltage withstand capability and are electrically compatible with 55V applications. The higher voltage rating does not degrade performance in 55V circuits; it simply provides additional safety margin. These parts are suitable substitutes when voltage headroom is beneficial to circuit design.

Q: Are all substitute parts RoHS3 compliant?

A: All recommended active substitutes carry RoHS3 compliance certification. The IPP040N06N3GXKSA1 is RoHS3 compliant but carries "Not For New Designs" status and should not be selected for new production applications.

Q: What is the significance of the TO-220-3 package requirement?

A: The TO-220-3 package is a three-terminal through-hole configuration with standardized pin spacing and thermal characteristics. All substitute parts must use this package format to ensure mechanical compatibility with existing PCB layouts, heatsink mounting arrangements, and thermal management systems.

Q: Can I use a substitute part with lower current rating than 220A?

A: Substitutes with lower current ratings (such as IRFB3306PBF at 120A or CSD18532KCS at 100A) are only suitable for applications where the circuit current requirement does not exceed the substitute part's rating. These parts are not recommended for designs that require the full 220A capability of the original part.

Q: What is the difference between IRFB3207PBF and IRFB3207ZPBF?

A: Both parts are Infineon HEXFET® devices with 75V voltage rating and TO-220-3 packaging. The IRFB3207PBF is rated for 170A continuous current with 4.5mOhm on-state resistance. The IRFB3207ZPBF is rated for 120A continuous current with 4.1mOhm on-state resistance. Selection depends on the specific current requirement of the application.

Q: Why is the IPP040N06N3GXKSA1 not recommended for new designs?

A: The IPP040N06N3GXKSA1 carries "Not For New Designs" product status from Infineon Technologies. While the part is electrically functional and available in inventory, this status indicates that the manufacturer is not recommending this device for new product development. For new designs, select from parts with Active product status.

Q: Are all substitute parts available in the same packaging format?

A: All substitute parts listed use the TO-220-3 through-hole package format, ensuring mechanical and thermal compatibility. Some parts are supplied in tube packaging while others may use alternative packaging; however, the component package type (TO-220-3) remains consistent across all substitutes.
