IRF1407STRR N-Channel 75V 100A MOSFET Equivalent & Substitute Parts

Part Overview

The IRF1407STRR is an N-Channel MOSFET manufactured by Infineon Technologies, rated for 75V drain-to-source voltage and 100A continuous drain current in the D2PAK surface mount package. This device belongs to the HEXFET® series and is classified as Obsolete. Due to its obsolete status and limited availability relative to active alternatives, equivalent and substitute parts are necessary for new designs and ongoing production support. Substitute parts maintain electrical compatibility within specified parameter ranges while offering improved availability, compliance status, or enhanced performance characteristics.

Substitute Part Grouping Explanation

Substitute parts are grouped into two categories based on electrical and mechanical compatibility with the IRF1407STRR:

Category 1: Manufacturer-Recommended Direct Equivalents (Infineon OptiMOS™ Series) These parts maintain identical voltage and current ratings (75V, 100A or 75V, 80A) with improved on-state resistance, lower gate charge, and higher power dissipation capability. All are surface mount D2PAK packages with RoHS3 compliance and active or last-time-buy product status.

Category 2: Parametric Equivalents and Cross-Manufacturer Alternatives These parts share the same package footprint (D2PAK/TO-263-3) and operate within the same voltage class (55V to 75V). Current ratings range from 75A to 110A. Substitution is valid when application requirements permit operation at the specified current and voltage ratings of the alternative device.

Key Parameters Determining Substitution Validity:

Drain-to-Source Voltage (Vdss): Must equal or exceed application requirement
Continuous Drain Current (Id): Must equal or exceed application requirement
Package Type: D2PAK (TO-263-3) for direct mechanical compatibility
On-State Resistance (Rds On): Lower values indicate improved performance
Operating Temperature Range: Must encompass application operating conditions
RoHS and Compliance Status: Required for regulated applications

Engineering Selection Recommendations

Primary Recommendation: IRF1407STRLPBF This part is electrically and mechanically identical to the IRF1407STRR with identical electrical specifications (75V, 100A, 7.8mOhm Rds On). The primary advantage is Active product status with ROHS3 compliance, ensuring long-term availability and regulatory compliance for new designs. Inventory availability is significantly higher (21,400 units) compared to the obsolete IRF1407STRR.

Secondary Recommendation: IPB100N08S207ATMA1 Manufacturer-recommended Infineon OptiMOS™ alternative rated for 75V, 100A operation. Offers improved performance with lower on-state resistance (6.8mOhm vs. 7.8mOhm), reduced gate charge (200nC vs. 250nC), and higher power dissipation capability (300W vs. 200W). Product status is Last Time Buy with ROHS3 compliance. Suitable for applications where improved efficiency and thermal performance are beneficial.

Tertiary Recommendation: IPB80N08S207ATMA1 Infineon OptiMOS™ device rated for 75V, 80A operation. Applicable when application current requirements do not exceed 80A. Offers improved on-state resistance (7.1mOhm), significantly reduced gate charge (180nC), and higher power dissipation (300W). Active product status ensures long-term availability. Lower current rating reduces thermal stress in current-limited applications.

Cross-Manufacturer Alternatives:

FDB060AN08A0 (onsemi PowerTrench®): 75V, 80A rating with 6mOhm on-state resistance and 255W power dissipation. Active status with ROHS3 compliance. Suitable for applications where current does not exceed 80A and improved efficiency is required.

BUK9606-75B,118 (Nexperia TrenchMOS™): 75V, 75A rating with superior on-state resistance (5.5mOhm) and lowest gate charge (95nC) among 75V alternatives. Active status with AEC-Q101 automotive qualification. Recommended for automotive and high-efficiency applications where current requirements are 75A or less.

Voltage-Reduced Alternatives (Not Recommended for Direct Substitution): FDB5800 (60V, 80A) and AOB2606L (60V, 72A) operate at reduced voltage ratings. These are suitable only when application maximum voltage does not exceed 60V. IXTA110N055T2 (55V, 110A) operates at 55V and is suitable only when application maximum voltage does not exceed 55V.

Frequently Asked Questions (FAQ)

Q1: Can IRF1407STRLPBF directly replace IRF1407STRR in existing designs? Yes. IRF1407STRLPBF is electrically and mechanically identical to IRF1407STRR. All electrical parameters, package dimensions, and pin configurations are equivalent. The primary difference is product status (Active vs. Obsolete) and RoHS compliance (ROHS3 vs. Non-compliant). No circuit modifications are required.

Q2: What is the advantage of IPB100N08S207ATMA1 over IRF1407STRLPBF? IPB100N08S207ATMA1 offers improved performance characteristics: lower on-state resistance (6.8mOhm vs. 7.8mOhm reduces conduction losses), reduced gate charge (200nC vs. 250nC improves switching speed), and higher power dissipation capability (300W vs. 200W). These improvements result in lower heat generation and improved efficiency. Both maintain 75V, 100A ratings and D2PAK packaging.

Q3: Can I use IPB80N08S207ATMA1 if my application requires 100A continuous current? No. IPB80N08S207ATMA1 is rated for maximum 80A continuous drain current. Using this device in a 100A application exceeds its current rating and will result in excessive junction temperature, reduced device lifetime, and potential failure. Use only when application current requirements do not exceed 80A.

Q4: Are BUK9606-75B,118 and IXTA110N055T2 suitable replacements? BUK9606-75B,118 is suitable when application current does not exceed 75A. It maintains the 75V voltage rating and offers superior on-state resistance (5.5mOhm). IXTA110N055T2 is suitable only when application maximum voltage does not exceed 55V; it offers higher current capability (110A) but reduced voltage rating. Verify application voltage and current requirements before selection.

Q5: Why are FDB5800 and AOB2606L listed if they have lower voltage ratings? These devices are included for applications where the maximum operating voltage is 60V or less. FDB5800 (60V, 80A) and AOB2606L (60V, 72A) offer alternative sourcing options and improved on-state resistance (6mOhm and 6.2mOhm respectively) for voltage-reduced applications. They are not suitable for circuits requiring full 75V operation.

Q6: What does "Last Time Buy" product status mean? Last Time Buy indicates the manufacturer will accept orders for a limited period before discontinuing the part. IPB100N08S207ATMA1 carries this status. Existing inventory may be available, but future procurement should transition to Active alternatives such as IPB80N08S207ATMA1 or IRF1407STRLPBF to ensure long-term supply continuity.

Q7: Are all substitute parts RoHS3 compliant? All recommended substitutes except BUK9609-75A,118 carry explicit ROHS3 compliance certification. BUK9609-75A,118 compliance status is not specified in available data. For applications requiring RoHS compliance verification, confirm with the component supplier before procurement.

Q8: Do substitute parts require PCB layout modifications? No. All substitute parts use the D2PAK (TO-263-3) package with identical pin configuration and mechanical dimensions. Existing PCB layouts designed for IRF1407STRR accommodate all listed substitutes without modification. Thermal management considerations may improve with lower on-state resistance alternatives.

Q9: Which substitute offers the best thermal performance? IPB100N08S207ATMA1 and IPB80N08S207ATMA1 offer the highest power dissipation capability (300W) combined with low on-state resistance. BUK9606-75B,118 provides the lowest on-state resistance (5.5mOhm) among 75V alternatives, resulting in minimal conduction losses. Selection depends on whether maximum current (100A) or maximum efficiency is the priority.

Q10: Can I mix IRF1407STRR and substitute parts in the same production batch? Electrical compatibility is maintained across all recommended substitutes. However, mixing obsolete (IRF1407STRR) and active parts (IRF1407STRLPBF, IPB100N08S207ATMA1) in the same batch introduces supply chain risk and complicates inventory management. Standardize on a single active part number for new production runs.
