IXFH20N100P N-Channel 1000V 20A MOSFET Equivalent & Substitute Parts

Part Overview

The IXFH20N100P is an N-Channel MOSFET manufactured by IXYS, rated for 1000V drain-to-source voltage with 20A continuous drain current at 25°C. This device is part of the HiPerFET™ series and is housed in a TO-247AD through-hole package. The part is currently in active production status with 1559 units in stock.

Finding equivalent and substitute parts for the IXFH20N100P becomes necessary when addressing supply chain constraints, design optimization requirements, or application-specific performance needs. Substitute parts must maintain compatibility across critical electrical parameters including voltage rating, current capacity, gate charge characteristics, and thermal performance while accommodating minor variations in on-resistance and input capacitance.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the IXFH20N100P are identified based on strict alignment with the following critical electrical and mechanical parameters:

Voltage Rating Compatibility: All substitute parts must maintain the 1000V drain-to-source voltage (Vdss) rating to ensure safe operation within the same circuit topology and voltage stress conditions.

Current Capacity: Substitute parts must support continuous drain current (Id) at or above 20A at 25°C. Parts with lower current ratings are not acceptable as they cannot handle the design's current demands.

Package Compatibility: All substitute parts must use through-hole mounting in a TO-247 family package to ensure mechanical and thermal interface compatibility with existing PCB layouts and heatsink assemblies.

Gate Drive Voltage: Substitute parts must operate with a maximum on-resistance specification at 10V gate drive voltage, ensuring compatibility with standard gate driver circuits.

Operating Temperature Range: Substitute parts must support the full -55°C to 150°C junction temperature operating range to maintain performance across all environmental conditions.

Regulatory Compliance: All substitute parts must maintain ROHS3 compliance and REACH unaffected status to satisfy manufacturing and environmental requirements.

The APT17F100B from Microchip Technology meets these substitution criteria with the exception of continuous drain current, which is rated at 17A instead of 20A. This represents a 15% reduction in current capacity and requires application-level evaluation.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection: The IXFH20N100P remains the preferred selection for applications requiring the full 20A continuous drain current specification. This part is in active production status with adequate inventory (1559 units) and carries full ROHS3 compliance and REACH unaffected certification.

Substitute Part Consideration: The APT17F100B from Microchip Technology is suitable as a substitute only in applications where the continuous drain current requirement can be reduced to 17A or where the application operates below this threshold under normal operating conditions. This part is also in active production status with 1063 units in stock and maintains identical regulatory compliance.

Electrical Trade-offs: The APT17F100B exhibits higher on-resistance (800 mOhm @ 9A, 10V versus 570 mOhm @ 10A, 10V), resulting in increased power dissipation and heat generation. The substitute part also carries higher gate charge (150 nC versus 126 nC), which may impact gate driver performance and switching frequency characteristics. Input capacitance is lower in the substitute part (4845 pF versus 7300 pF), which may reduce gate drive requirements.

Thermal Considerations: The APT17F100B has a maximum power dissipation rating of 625W compared to 660W for the IXFH20N100P. Combined with the higher on-resistance, thermal management design must account for increased heat generation when using the substitute part.

Regulatory Compliance: Both parts maintain identical compliance status across ROHS3, REACH, and moisture sensitivity classifications, ensuring no regulatory barriers to substitution.

Frequently Asked Questions (FAQ)

Q: Can the APT17F100B be used as a direct replacement for the IXFH20N100P?

A: The APT17F100B is mechanically compatible (TO-247-3 package, through-hole mounting) and electrically compatible for voltage rating and operating temperature range. However, the 17A continuous drain current rating is 15% lower than the IXFH20N100P's 20A rating. Substitution is only valid if the application's actual current demand does not exceed 17A under any operating condition.

Q: What are the key electrical differences between these parts?

A: The primary differences are continuous drain current (20A versus 17A), on-resistance (570 mOhm versus 800 mOhm), gate charge (126 nC versus 150 nC), and input capacitance (7300 pF versus 4845 pF). These differences result in higher power dissipation and different gate drive characteristics for the substitute part.

Q: Are both parts suitable for high-frequency switching applications?

A: The IXFH20N100P has lower gate charge (126 nC) and higher input capacitance (7300 pF), which may provide different switching characteristics compared to the APT17F100B (150 nC gate charge, 4845 pF input capacitance). Application-specific gate driver design must account for these parameter differences.

Q: Do both parts require the same heatsink design?

A: No. The APT17F100B has higher on-resistance and lower maximum power dissipation (625W versus 660W). Thermal management design must be recalculated for the substitute part to account for increased on-resistance losses, which may require a larger or more efficient heatsink.

Q: Are there any package compatibility issues?

A: Both parts use TO-247-3 through-hole packages and are mechanically compatible with standard TO-247 heatsink assemblies and PCB layouts. No package-level modifications are required.

Q: What is the gate threshold voltage difference, and does it matter?

A: The APT17F100B has a lower gate threshold voltage (5V @ 1mA versus 6.5V @ 1mA). This may result in slightly different turn-on characteristics and should be evaluated in gate driver circuits with marginal gate voltage margins.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the IXFH20N100P and APT17F100B are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the moisture sensitivity level for both parts?

A: Both parts carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity concerns and no special storage or handling requirements.
