IXFV22N50P N-Channel 500V 22A MOSFET Equivalent & Substitute Parts

Part Overview

The IXFV22N50P is an N-Channel MOSFET manufactured by IXYS, rated for 500V drain-to-source voltage with 22A continuous drain current at 25°C. This device is housed in a PLUS220 package (TO-220-3 Short Tab) and is designed for through-hole mounting applications requiring high-voltage switching capability. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IXFV22N50P is determined by strict equivalence across the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Drain-to-Source Voltage (Vdss): Must equal or exceed 500V
• Continuous Drain Current (Id): Must equal or exceed 22A at 25°C
• Drive Voltage: Must operate at 10V gate drive
• Gate Threshold Voltage (Vgs(th)): Must fall within compatible range for circuit operation
• Operating Temperature Range: Must span -55°C to 150°C minimum

Mechanical Equivalence Criteria:

• Mounting Type: Through-hole configuration required
• Package Compatibility: Physical dimensions and pin configuration must accommodate existing PCB layouts

The APT24F50B from Microchip Technology meets these substitution criteria. It provides equivalent voltage rating (500V Vdss), exceeds the current requirement (24A vs. 22A), maintains 10V drive voltage compatibility, and operates across the required temperature range. The device is housed in a TO-247-3 package, which is a through-hole alternative to the PLUS220 package.

Parameter Comparison

Engineering Selection Recommendations

The APT24F50B is a functionally equivalent substitute for the obsolete IXFV22N50P based on the following factors:

Electrical Compatibility: Both devices share identical 500V Vdss rating and 10V drive voltage specification. The APT24F50B provides higher continuous drain current (24A vs. 22A), delivering improved thermal margin and reduced on-state losses (240mOhm vs. 270mOhm at 11A, 10V). Both operate across the full -55°C to 150°C temperature range.

Product Status and Compliance: The IXFV22N50P is classified as obsolete, whereas the APT24F50B is active and in production. The APT24F50B carries RoHS3 compliance certification, ensuring alignment with current regulatory requirements. Both devices maintain REACH Unaffected status.

Package Consideration: The APT24F50B uses a TO-247-3 package instead of the PLUS220 (TO-220-3 Short Tab). Both are through-hole packages with different physical footprints. PCB layout modification is required to accommodate the TO-247-3 package dimensions.

Frequently Asked Questions (FAQ)

Q: Can the APT24F50B directly replace the IXFV22N50P without circuit modification?

A: Electrical substitution is valid. The APT24F50B meets or exceeds all critical electrical parameters (Vdss, Id, Vgs, temperature range). However, the TO-247-3 package has different physical dimensions than the PLUS220 package, requiring PCB layout changes for mounting.

Q: What is the significance of the higher drain current rating (24A vs. 22A) on the APT24F50B?

A: The higher current rating provides additional thermal headroom and reduces on-state power dissipation. This allows the substitute device to operate at lower junction temperatures under identical load conditions, improving reliability and extending component life.

Q: Are there differences in gate charge between these devices?

A: Yes. The IXFV22N50P has a maximum gate charge of 50 nC at 10V, while the APT24F50B specifies 90 nC at 10V. Higher gate charge increases switching losses and requires higher gate drive current. Gate drive circuits must be verified for compatibility with the increased charge requirement.

Q: What is the impact of the different gate threshold voltages?

A: The IXFV22N50P specifies Vgs(th) of 5.5V at 2.5mA, while the APT24F50B specifies 5.0V at 1mA. Both values fall within the ±30V maximum gate voltage specification. Circuit gate drive voltage must exceed the threshold voltage to ensure full device turn-on; both devices are compatible with standard 10V to 15V gate drive levels.

Q: Does the input capacitance difference affect circuit performance?

A: The APT24F50B has higher input capacitance (3630 pF vs. 2630 pF at 25V). This increases gate charge and switching time. Gate drive circuits with sufficient current capability must be confirmed to handle the increased capacitive load.

Q: Is the TO-247-3 package suitable for the same thermal management approach as PLUS220?

A: Both packages are through-hole designs with similar thermal characteristics. The TO-247-3 package provides equivalent or superior thermal performance. Existing heatsink mounting solutions may require mechanical adaptation due to different package geometry and lead configuration.

Q: What compliance certifications should be verified for the substitute part?

A: The APT24F50B carries RoHS3 compliance, which is current regulatory standard. Both devices maintain REACH Unaffected status. Verify that RoHS3 compliance aligns with your application and regional requirements.
