IXFV74N20P N-Channel MOSFET Equivalent & Substitute Parts

Part Overview

The IXFV74N20P is an N-Channel 200V 74A MOSFET manufactured by IXYS in the PolarHT™ HiPerFET™ series, housed in a PLUS220 through-hole package. This device is classified as obsolete product status. Identification of equivalent and substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades where the original part is no longer readily available from primary sources.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IXFV74N20P is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

• Drain to Source Voltage (Vdss): 200V minimum
• Continuous Drain Current (Id): Equal to or greater than 74A
• Package Type: Through-hole TO-220-3 configuration
• Gate Drive Voltage: 10V nominal
• Operating Temperature Range: Minimum -55°C to 175°C

Secondary Compatibility Parameters:

• On-State Resistance (Rds On): Lower or equal values preferred for thermal performance
• Gate Charge (Qg): Lower values reduce switching losses
• Power Dissipation: Adequate thermal handling capability

Substitute parts must satisfy the primary electrical specifications (voltage and current ratings) and maintain mechanical compatibility through identical through-hole TO-220-3 packaging. Parts that meet or exceed these parameters are classified as direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: STP75NF20 (STMicroelectronics)

The STP75NF20 is the preferred substitute for the IXFV74N20P. This device matches the continuous drain current specification at 75A, exceeding the original 74A rating. The on-state resistance of 34 mOhm is identical to the IXFV74N20P, ensuring equivalent thermal performance. The STP75NF20 maintains the same 200V Vdss rating and TO-220-3 package configuration. The device is RoHS3 compliant and carries active product status, ensuring long-term availability and supply chain stability. The operating temperature range extends to 150°C, which is 25°C lower than the original part but remains suitable for most industrial applications.

Secondary Substitute: FDP2614 (onsemi)

The FDP2614 provides an alternative with 62A continuous drain current, which is 12A below the original specification. This part is suitable for applications where the full 74A current rating is not required. The FDP2614 offers superior on-state resistance at 27 mOhm, providing improved thermal efficiency. RoHS3 compliance and active product status support long-term design continuity. The operating temperature range is limited to 150°C.

Tertiary Substitute: IPP320N20N3GXKSA1 (Infineon Technologies)

The IPP320N20N3GXKSA1 is suitable only for applications requiring 34A or less continuous drain current. This part does not meet the full current specification of the IXFV74N20P and should be used only in current-limited designs. The device offers the lowest gate charge at 29 nC, reducing switching losses. Operating temperature range extends to 175°C, matching the original part. RoHS3 compliance and active product status ensure availability.

Frequently Asked Questions (FAQ)

Q: Can the FDP2614 be used as a direct replacement for the IXFV74N20P?

A: The FDP2614 is mechanically compatible through identical TO-220-3 packaging and matches the 200V voltage rating. However, the continuous drain current is rated at 62A, which is 12A below the IXFV74N20P specification. Use this substitute only in applications where the maximum current requirement does not exceed 62A.

Q: What is the primary advantage of the STP75NF20 over the original IXFV74N20P?

A: The STP75NF20 exceeds the original current rating at 75A while maintaining identical on-state resistance of 34 mOhm. The device carries active product status, ensuring reliable long-term availability compared to the obsolete IXFV74N20P.

Q: Is the IPP320N20N3GXKSA1 suitable for high-current applications?

A: No. The IPP320N20N3GXKSA1 is rated for only 34A continuous drain current, significantly below the IXFV74N20P specification of 74A. This part is suitable only for lower-current designs or as a substitute in current-limited circuits.

Q: Are all substitute parts RoHS compliant?

A: Yes. The FDP2614, IPP320N20N3GXKSA1, and STP75NF20 are all RoHS3 compliant, meeting environmental and regulatory requirements for modern electronics manufacturing.

Q: What is the impact of operating temperature range differences?

A: The IXFV74N20P and IPP320N20N3GXKSA1 support operation to 175°C. The FDP2614 and STP75NF20 are limited to 150°C. For applications requiring operation above 150°C, use the IPP320N20N3GXKSA1 or verify that the design does not exceed 150°C junction temperature.

Q: Can these substitutes be used interchangeably in existing PCB designs?

A: All substitute parts use TO-220-3 through-hole packaging and are mechanically compatible with the original IXFV74N20P footprint. Electrical performance differences, particularly in current rating and on-state resistance, must be verified against circuit requirements before implementation.

Q: Which substitute offers the best thermal performance?

A: The FDP2614 provides the lowest on-state resistance at 27 mOhm, resulting in the lowest conduction losses and superior thermal efficiency. However, this advantage is offset by the lower current rating of 62A.
