IXFH16N60P3 Equivalent & Substitute Parts

Part Overview

The IXFH16N60P3 is an N-Channel 600V 16A MOSFET manufactured by IXYS in the HiPerFET™ and Polar3™ series. This device is housed in a TO-247 through-hole package and is rated for 347W maximum power dissipation at case temperature. The part is currently Active in product status and fully compliant with RoHS3 and REACH regulations.

Substitute parts become necessary when the primary component experiences extended lead times, inventory constraints, or when design requirements permit operation within alternative electrical and mechanical specifications. The IXFH16N60P3 can be substituted with parts that maintain compatibility across critical parameters including drain-source voltage rating, continuous drain current capability, gate drive voltage, package type, and operating temperature range.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IXFH16N60P3 is determined by the following critical parameters:

Voltage Rating Compatibility: The drain-source voltage (Vdss) must be equal to or greater than 600V. Parts rated at higher voltages (such as 800V) are acceptable for 600V applications and provide additional design margin.

Current Capability: The continuous drain current (Id) at 25°C must meet or exceed the application requirement. The IXFH16N60P3 is rated at 16A; substitute parts with lower current ratings (11A) are acceptable only when the application current demand does not exceed the substitute part's rating.

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 mounting arrangements.

Gate Drive Voltage: The drive voltage specification (10V) and maximum gate voltage (±30V or ±20V) must be compatible with the circuit's gate driver capabilities.

Operating Temperature Range: The operating temperature range of -55°C to 150°C (TJ) must be maintained or exceeded by substitute parts.

Regulatory Compliance: All substitute parts must maintain RoHS3 compliance and REACH unaffected status to satisfy procurement and environmental requirements.

Parameter Comparison

Engineering Selection Recommendations

IRFPC50APBF (Vishay Siliconix): This part is suitable as a direct substitute when application current requirements do not exceed 11A continuous drain current. The IRFPC50APBF maintains identical 600V voltage rating and TO-247-3 package compatibility. The part is Active in product status, ensuring long-term availability and supply chain stability. RoHS3 compliance and REACH unaffected status align with the primary part's regulatory requirements. The higher gate charge (70 nC versus 36 nC) and input capacitance (2100 pF versus 1830 pF) require verification that gate driver circuitry can accommodate these increased switching losses.

SPW11N80C3FKSA1 (Infineon Technologies): This part provides a higher voltage rating (800V) suitable for applications requiring additional voltage margin above the 600V specification. The part maintains 11A continuous drain current and TO-247-3 package compatibility. However, this part carries a "Not For New Designs" product status, indicating that Infineon has discontinued active development and support. While currently in stock, this part should be selected only when existing designs require continuation or when 800V rating provides specific circuit advantages. The lower maximum gate voltage (±20V versus ±30V) requires confirmation that gate driver output does not exceed ±20V. RoHS3 compliance and REACH unaffected status are maintained.

Current Availability: The IXFH16N60P3 maintains 1062 pieces in stock. The IRFPC50APBF has 2225 pieces available, and the SPW11N80C3FKSA1 has 3312 pieces available, providing alternative sourcing options for extended production runs.

Frequently Asked Questions (FAQ)

Q: Can the IRFPC50APBF replace the IXFH16N60P3 in all applications?

A: The IRFPC50APBF is suitable for applications where continuous drain current does not exceed 11A. The IXFH16N60P3 is rated at 16A continuous current; therefore, applications requiring the full 16A rating cannot use the IRFPC50APBF as a direct substitute. Both parts share identical 600V voltage rating, TO-247-3 package, and operating temperature range, ensuring mechanical and thermal compatibility.

Q: What is the significance of the SPW11N80C3FKSA1 "Not For New Designs" status?

A: The "Not For New Designs" designation indicates that Infineon has concluded active development and support for this part. While the part remains available in inventory and maintains full RoHS3 compliance, it is intended for sustaining existing designs rather than new product development. New designs should prioritize the IXFH16N60P3 or IRFPC50APBF, both of which carry Active product status.

Q: Are there differences in gate drive requirements between these parts?

A: All three parts operate at 10V drive voltage. However, gate charge differs significantly: IXFH16N60P3 (36 nC), IRFPC50APBF (70 nC), and SPW11N80C3FKSA1 (85 nC). Higher gate charge increases switching losses and requires gate driver circuitry capable of supplying higher peak currents. The SPW11N80C3FKSA1 also specifies a maximum gate voltage of ±20V compared to ±30V for the other parts; gate driver output must not exceed this limit.

Q: Do all substitute parts maintain the same thermal characteristics?

A: No. Maximum power dissipation differs: IXFH16N60P3 (347W), IRFPC50APBF (180W), and SPW11N80C3FKSA1 (156W). Lower power dissipation ratings in substitute parts reflect their reduced current capability. Thermal design calculations must account for these differences; applications requiring the full 347W dissipation capability cannot use the lower-rated substitutes.

Q: Is the TO-247-3 package identical across all three parts?

A: All three parts use the TO-247-3 through-hole package, ensuring mechanical compatibility with existing PCB layouts and heatsink mounting arrangements. The IXFH16N60P3 uses the IXTH variant, the IRFPC50APBF uses TO-247AC, and the SPW11N80C3FKSA1 uses PG-TO247-3-1; these are functionally equivalent package designations within the TO-247-3 family.

Q: What is the impact of different input capacitance values?

A: Input capacitance (Ciss) affects gate charge and switching speed. The IXFH16N60P3 has 1830 pF at 25V, the IRFPC50APBF has 2100 pF at 25V, and the SPW11N80C3FKSA1 has 1600 pF at 100V. Higher input capacitance increases gate charge and switching losses. The SPW11N80C3FKSA1 measurement at 100V versus 25V reflects different test conditions and should be considered when comparing switching performance.

Q: Are all parts compliant with current environmental regulations?

A: Yes. All three parts are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component procurement and use.
