IXFH270N06T3 Equivalent & Substitute Parts

Part Overview

The IXFH270N06T3 is an N-Channel MOSFET rated for 60V drain-to-source voltage with 270A continuous drain current at 25°C. This device is manufactured by IXYS using HiperFET™ and TrenchT3™ technology in a TO-247 through-hole package. The part carries a Last Time Buy product status, indicating that the original manufacturer has discontinued or will discontinue production. Equivalent and substitute parts are necessary to maintain design continuity and ensure long-term component availability for new production runs and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of N-Channel MOSFETs is determined by compatibility across the following critical parameters:

Voltage Rating Compatibility: The substitute part must have a Vdss rating equal to or greater than the original part. The IXFH270N06T3 operates at 60V; therefore, substitute parts rated at 60V or higher are acceptable.

Current Handling Capability: The substitute part's continuous drain current (Id) must meet or exceed the application requirement. The original part is rated for 270A at 25°C. Substitute parts with lower current ratings may be used only if the application does not require the full 270A capacity.

On-State Resistance (Rds On): Lower Rds On values indicate better efficiency and reduced power dissipation. Substitute parts with comparable or lower Rds On values maintain or improve thermal performance.

Gate Charge (Qg): Gate charge affects switching speed and driver circuit requirements. Substitute parts with similar or lower gate charge values ensure compatible gate drive characteristics.

Package and Mounting: All substitute parts must use the TO-247-3 through-hole package to ensure mechanical and thermal compatibility with existing PCB layouts and heatsink assemblies.

Compliance and Status: All substitute parts must maintain RoHS3 compliance, MSL Level 1 rating, and REACH compliance to satisfy regulatory and supply chain requirements.

Parameter Comparison

Engineering Selection Recommendations

IRFP7537PBF is the primary substitute for applications where the full 270A current capacity of the IXFH270N06T3 is not required. This part maintains the 60V voltage rating and provides 172A continuous drain current with comparable on-state resistance (3.3 mOhm @ 100A, 10V). The IRFP7537PBF is manufactured by Infineon Technologies with Active product status, ensuring long-term availability. All regulatory certifications (RoHS3, MSL Level 1, REACH compliance) are maintained. Gate charge is slightly higher at 210 nC, which may require minor adjustments to gate drive timing but remains within acceptable operating parameters.

IRFP3206PBF is suitable for applications requiring lower current capacity (120A) at the same 60V rating. This part offers the lowest on-state resistance (3.0 mOhm @ 75A, 10V) and the lowest gate charge (170 nC), resulting in improved efficiency and faster switching characteristics. The IRFP3206PBF is Active status with full regulatory compliance. Power dissipation is reduced to 280W, which may require thermal design review for high-power applications.

IRFP3077PBF provides a higher voltage rating (75V) with 120A continuous drain current. This part is suitable only for applications where the higher voltage margin is beneficial or required. The 75V rating introduces design margin but does not provide the current capacity of the original part. This substitute is Active status with full compliance certifications.

All three substitute parts are available in high inventory quantities, ensuring supply chain continuity. Selection should be based on specific application current requirements and thermal design constraints.

Frequently Asked Questions (FAQ)

Q: Can the IRFP7537PBF directly replace the IXFH270N06T3 in all applications?

A: The IRFP7537PBF is a direct mechanical and electrical substitute for applications requiring up to 172A continuous drain current. If the original design requires the full 270A capacity of the IXFH270N06T3, the IRFP7537PBF is not suitable. Verify application current requirements before substitution.

Q: What is the difference between TO-247 and TO-247AC packages?

A: Both TO-247 and TO-247AC are three-lead through-hole packages with identical mechanical dimensions and pin configurations. The designations refer to minor manufacturing variations by different suppliers. All substitute parts listed use TO-247-3 package specifications and are mechanically compatible with existing PCB layouts.

Q: Are there current capacity limitations when using IRFP3206PBF or IRFP3077PBF?

A: Yes. The IRFP3206PBF and IRFP3077PBF are rated for 120A continuous drain current, compared to 270A for the IXFH270N06T3. These parts are suitable only for applications where the design current does not exceed 120A. Exceeding this rating will result in device failure and potential circuit damage.

Q: Do all substitute parts maintain the same operating temperature range?

A: Yes. All substitute parts listed operate across the same temperature range (-55°C to 175°C junction temperature) as the original IXFH270N06T3, ensuring thermal compatibility in existing designs.

Q: What is the impact of different gate charge values on circuit design?

A: Gate charge affects the speed at which the MOSFET switches on and off. The IRFP3206PBF has the lowest gate charge (170 nC), enabling faster switching. The IRFP3077PBF has the highest gate charge (220 nC), requiring slightly longer switching times. Gate drive circuits must be verified to ensure adequate current and voltage to charge the gate within the required switching time window.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed carry RoHS3 compliance certification, meeting regulatory requirements for hazardous substance restrictions. MSL Level 1 rating applies to all parts, indicating unlimited shelf life under standard storage conditions.

Q: Which substitute part offers the best efficiency?

A: The IRFP3206PBF provides the lowest on-state resistance (3.0 mOhm @ 75A, 10V) and lowest gate charge (170 nC), resulting in the lowest conduction losses and fastest switching characteristics. However, this part is limited to 120A continuous current and 280W power dissipation, which may not suit high-power applications.
