IRF6215PBF P-Channel MOSFET Equivalent & Substitute Parts

Part Overview

The IRF6215PBF is a P-Channel MOSFET manufactured by Infineon Technologies, rated for 150V drain-to-source voltage with 13A continuous drain current at 25°C. This device is packaged in TO-220AB through-hole configuration and belongs to the HEXFET® series. The IRF6215PBF is classified as obsolete product status, making identification of equivalent and substitute parts essential for ongoing design support and procurement continuity. Substitute parts must maintain electrical compatibility across voltage ratings, current handling, and thermal characteristics while accommodating the through-hole TO-220-3 package standard.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IRF6215PBF is determined by strict adherence to the following electrical and mechanical parameters:

Primary Compatibility Criteria:

• Drain-to-Source Voltage (Vdss): Must equal or exceed 150V
• FET Type: Must be P-Channel
• Package: Must be TO-220-3 through-hole configuration
• Technology: Must be MOSFET (Metal Oxide)
• Mounting Type: Must be Through Hole

Secondary Compatibility Criteria:

• Continuous Drain Current (Id): Substitute must support minimum 13A at 25°C
• Power Dissipation: Substitute must support minimum 110W
• Gate Threshold Voltage (Vgs(th)): Must be compatible with 10V drive voltage
• RoHS3 Compliance: Required for regulatory alignment
• Moisture Sensitivity Level: MSL 1 (Unlimited)

The two identified substitute parts—IXTP15P15T and IXTP36P15P—both satisfy all primary and secondary criteria. Both devices are manufactured by IXYS, maintain active product status, and exceed the electrical performance envelope of the obsolete IRF6215PBF while preserving package compatibility.

Parameter Comparison

Engineering Selection Recommendations

IXTP15P15T Selection Criteria: The IXTP15P15T provides a direct performance upgrade with 15A continuous drain current versus the IRF6215PBF's 13A rating. This substitute maintains the 150V Vdss specification and improves power dissipation capacity to 150W. The IXTP15P15T features lower on-resistance (240mOhm) and reduced gate charge (48nC), resulting in improved switching efficiency. Active product status ensures long-term availability and supply chain stability. The IXTP15P15T is suitable for applications requiring minimal performance margin above the original 13A specification.

IXTP36P15P Selection Criteria: The IXTP36P15P represents a high-performance substitute with 36A continuous drain current and 300W power dissipation capacity. This device delivers significantly lower on-resistance (110mOhm at 18A) and maintains the 150V Vdss rating. The IXTP36P15P is appropriate for applications requiring substantial thermal headroom, higher current capacity, or designs transitioning to higher-power configurations. Active product status and full RoHS3 compliance support long-term design continuity.

Compliance Alignment: Both substitute parts maintain RoHS3 compliance, MSL 1 (Unlimited) moisture sensitivity rating, and REACH unaffected status, ensuring regulatory alignment with the original IRF6215PBF. Both devices are packaged in TO-220-3 through-hole configuration, supporting direct mechanical and electrical integration into existing PCB layouts.

Temperature Operating Range Consideration: The IRF6215PBF operates to 175°C junction temperature, while both IXYS substitutes operate to 150°C. Applications requiring operation above 150°C junction temperature require thermal design review to ensure substitute parts remain within specified operating limits.

Frequently Asked Questions (FAQ)

Q: Can IXTP15P15T and IXTP36P15P be used interchangeably with IRF6215PBF?

A: Both IXYS devices are electrically and mechanically compatible substitutes for the IRF6215PBF. All three parts share identical 150V Vdss rating, P-Channel configuration, and TO-220-3 package. The primary differences are continuous drain current capacity and power dissipation ratings. Selection depends on application current requirements and thermal design constraints.

Q: What is the significance of the lower operating temperature range (150°C vs. 175°C) in the IXYS substitutes?

A: The IRF6215PBF supports junction temperatures to 175°C, while IXTP15P15T and IXTP36P15P are rated to 150°C maximum. Applications operating near or above 150°C junction temperature must verify thermal design compatibility with the substitute part's lower temperature rating. Most industrial and consumer applications operate well below 150°C and are unaffected by this specification difference.

Q: How do gate charge differences affect circuit performance?

A: Gate charge (Qg) determines the energy required to switch the MOSFET. The IRF6215PBF requires 66nC at 10V, while IXTP15P15T requires 48nC and IXTP36P15P requires 55nC. Lower gate charge reduces driver power dissipation and enables faster switching transitions. Both substitutes offer improved gate charge characteristics, resulting in lower driver stress and potentially improved overall circuit efficiency.

Q: Are there PCB layout considerations when substituting these parts?

A: All three devices use identical TO-220-3 package geometry, supporting direct PCB footprint compatibility. No layout modifications are required for mechanical or thermal pad placement. Electrical performance differences (particularly on-resistance and current capacity) may influence trace routing and thermal management design, but physical board layout remains unchanged.

Q: What is the impact of higher input capacitance in the IXYS substitutes?

A: The IRF6215PBF has 860pF input capacitance, while IXTP15P15T has 3650pF and IXTP36P15P has 3100pF. Higher input capacitance increases gate drive current requirements and may extend switching transition times. Gate driver circuits must provide sufficient current sourcing capability. Most modern gate drivers accommodate these capacitance levels without modification, but high-frequency switching applications should verify driver specifications.

Q: How does on-resistance affect thermal design?

A: On-resistance (Rds On) directly impacts power dissipation during conduction. The IRF6215PBF has 290mOhm, IXTP15P15T has 240mOhm, and IXTP36P15P has 110mOhm. Lower on-resistance reduces conduction losses and heat generation. Both substitutes offer improved on-resistance characteristics, reducing thermal management requirements and enabling more efficient designs.

Q: Is the IXTP36P15P overkill for applications originally designed for IRF6215PBF?

A: The IXTP36P15P provides substantial performance margin above the original 13A specification. While this device is electrically compatible and can be used as a direct substitute, applications with fixed current requirements may not require this performance level. The IXTP15P15T provides a more closely matched performance envelope with 15A rating, offering modest performance improvement without excessive over-specification.
