IPB65R225C7ATMA2 Equivalent & Substitute Parts

Part Overview

The IPB65R225C7ATMA2 is an N-Channel 650V 11A MOSFET manufactured by Infineon Technologies, part of the CoolMOS™ C7 series. This surface mount device in TO-263-3 (D2PAK) packaging is designed for high-voltage switching applications requiring 650V drain-to-source voltage capability. The part is currently Active in product status with 864 units in stock. Equivalent and substitute parts are identified based on matching electrical specifications and mechanical compatibility within the N-Channel MOSFET category for 600V to 650V applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IPB65R225C7ATMA2 is determined by the following criteria:

Primary Matching Parameters:

• Drain-to-Source Voltage (Vdss): 600V minimum to 650V maximum
• Continuous Drain Current (Id): 11A or greater at 25°C
• Package Type: TO-263-3 (D2PAK) surface mount
• Operating Temperature Range: -55°C to 150°C or wider
• RoHS Compliance: ROHS3 Compliant

Secondary Compatibility Factors:

• Gate Charge (Qg): Within ±30% of 20 nC for switching performance consistency
• Rds On (Max): Lower or equal values acceptable; higher values require thermal analysis
• Power Dissipation: 63W or greater capability
• Moisture Sensitivity Level: MSL 1 (Unlimited)

The identified substitute parts meet these criteria while maintaining functional equivalence in high-voltage switching applications.

Parameter Comparison

Engineering Selection Recommendations

FCB260N65S3 (onsemi SuperFET® III): This part provides equivalent 650V voltage rating and higher continuous drain current (12A vs. 11A). However, the product status is "Not For New Designs," which restricts its use in new development projects. The higher gate charge (24 nC vs. 20 nC) and increased Rds On (260 mOhm vs. 225 mOhm) result in higher switching losses and thermal dissipation. This substitute is suitable only for legacy system maintenance or replacement applications where design freeze is established. All compliance certifications (ROHS3, MSL 1) are equivalent.

STB18N60M2 (STMicroelectronics MDmesh™ II Plus): This part is Active in product status and suitable for new designs. The 600V Vdss rating is 50V lower than the main part, requiring verification that the application does not exceed 600V operating conditions. The higher continuous drain current (13A vs. 11A) and greater power dissipation capability (110W vs. 63W) provide thermal margin. The gate charge (21.5 nC) and Rds On (280 mOhm) are within acceptable ranges for switching performance. All compliance certifications match the main part. This substitute is recommended for applications operating at 600V or below where Active product status is required.

Frequently Asked Questions (FAQ)

Q: Can FCB260N65S3 be used as a direct replacement for IPB65R225C7ATMA2 in new product designs?

A: No. The FCB260N65S3 carries a "Not For New Designs" product status designation. While electrical parameters are compatible, this status restricts use in new development. It is suitable only for legacy system maintenance or replacement in established designs.

Q: What is the primary voltage limitation when substituting with STB18N60M2?

A: The STB18N60M2 has a maximum Vdss of 600V, compared to 650V for the IPB65R225C7ATMA2. Applications must operate at 600V or below. If the circuit design requires 650V capability, this substitute is not suitable.

Q: Are all three parts mechanically compatible in the same PCB footprint?

A: Yes. All three parts use TO-263-3 (D2PAK) surface mount packaging with identical lead configuration and thermal tab. PCB footprints are interchangeable without layout modification.

Q: How do gate charge differences affect circuit performance?

A: Gate charge (Qg) determines the energy required to switch the MOSFET. The main part requires 20 nC, while substitutes require 24 nC (FCB260N65S3) or 21.5 nC (STB18N60M2). Higher gate charge increases driver power consumption and may extend switching time. Driver circuits rated for 20 nC will function with higher Qg values but with reduced switching speed margin.

Q: What thermal considerations apply when substituting parts with different Rds On values?

A: Rds On directly affects conduction losses (P = I²R). The main part (225 mOhm) has lower losses than FCB260N65S3 (260 mOhm) or STB18N60M2 (280 mOhm). Higher Rds On generates more heat at the same current. Thermal design must accommodate the increased power dissipation, or current derating may be necessary.

Q: Are moisture sensitivity and RoHS compliance identical across all three parts?

A: Yes. All three parts are MSL 1 (Unlimited moisture sensitivity) and ROHS3 Compliant. Storage and handling requirements are identical. Environmental compliance certifications present no substitution barriers.

Q: Which substitute is recommended for new product development?

A: STB18N60M2 is the only substitute with Active product status, making it the appropriate choice for new designs. FCB260N65S3 is restricted to legacy applications. Selection between the main part and STB18N60M2 depends on whether the application voltage requirement is 650V (main part) or 600V (substitute).
