IXFV12N120P Equivalent & Substitute Parts

Part Overview

The IXFV12N120P is an N-Channel MOSFET rated for 1200V drain-to-source voltage with 12A continuous drain current at 25°C. Manufactured by IXYS, this device is housed in a PLUS220 package (TO-220-3 Short Tab) and is designed for high-voltage switching applications. The part is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IXFV12N120P is determined by equivalence in the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Drain-to-Source Voltage (Vdss): Must equal or exceed 1200V
• Continuous Drain Current (Id): Must equal or exceed 12A at 25°C
• Gate Drive Voltage: Must support 10V operation
• Maximum Gate Voltage (Vgs): Must accommodate ±30V
• Operating Temperature Range: Must span -55°C to 150°C

Mechanical Compatibility Criteria:

• Mounting Type: Through Hole configuration
• Package Classification: TO-220 family or equivalent footprint compatibility

The APT13F120B from Microchip Technology meets these substitution criteria with equivalent or superior electrical ratings and compatible through-hole mounting.

Engineering Selection Recommendations

APT13F120B as Primary Substitute:

The APT13F120B is the qualified substitute for the IXFV12N120P based on the following factors:

1. Electrical Compatibility: The APT13F120B exceeds the minimum electrical requirements of the IXFV12N120P. It provides 14A continuous drain current versus the original 12A, and 625W power dissipation versus 543W, offering improved thermal headroom and current capacity.

2. Voltage Rating Equivalence: Both devices maintain identical 1200V drain-to-source voltage ratings and ±30V gate voltage specifications, ensuring direct functional equivalence in high-voltage switching circuits.

3. Temperature Range Alignment: Operating temperature ranges are identical (-55°C to 150°C), confirming thermal performance compatibility across all operating conditions.

4. Product Status: The APT13F120B is classified as Active, ensuring ongoing availability and manufacturer support, contrasting with the obsolete status of the IXFV12N120P.

5. Regulatory Compliance: The APT13F120B carries RoHS3 compliance certification, meeting current environmental and regulatory standards. Both devices are REACH Unaffected and classified under ECCN EAR99.

Package Consideration: The APT13F120B uses a TO-247-3 package versus the PLUS220 (TO-220-3 Short Tab) of the original part. Both are through-hole configurations with compatible thermal and electrical characteristics, though PCB layout modifications may be required to accommodate the different package footprint.

Frequently Asked Questions (FAQ)

Q: Can the APT13F120B directly replace the IXFV12N120P without circuit modifications?

A: The APT13F120B is electrically equivalent and functionally compatible. However, the package difference (TO-247-3 versus TO-220-3 Short Tab) requires PCB layout adjustment. Pin configuration and electrical function are compatible.

Q: What is the significance of the higher gate charge (145 nC vs. 103 nC) in the APT13F120B?

A: The APT13F120B exhibits higher gate charge, which affects gate drive circuit design. This parameter determines the energy required to switch the device and influences switching speed. Gate drive circuits must be verified for compatibility with the increased charge requirement.

Q: Why does the APT13F120B have a lower gate threshold voltage (5V vs. 6.5V)?

A: The lower threshold voltage of the APT13F120B indicates it requires less gate voltage to initiate conduction. This is within acceptable operating margins for 10V gate drive applications and does not prevent substitution.

Q: Are there thermal management differences between the two packages?

A: The TO-247-3 package (APT13F120B) and TO-220-3 package (IXFV12N120P) have different thermal characteristics. The TO-247 package typically offers improved thermal performance due to its larger lead frame. Thermal analysis specific to your application is necessary to confirm adequate heat dissipation.

Q: What compliance certifications apply to the APT13F120B?

A: The APT13F120B is RoHS3 compliant, REACH Unaffected, and classified under ECCN EAR99. These certifications align with current regulatory requirements for electronic components in industrial and commercial applications.

Q: Is the APT13F120B available in the same packaging format as the IXFV12N120P?

A: No. The APT13F120B is supplied in TO-247-3 package format, while the IXFV12N120P uses PLUS220 (TO-220-3 Short Tab). Both are through-hole packages, but physical dimensions and PCB footprints differ and require layout redesign.

Q: What is the inventory status of the APT13F120B?

A: The APT13F120B is currently in active production with 1303 pieces available in new original stock, ensuring reliable procurement compared to the obsolete IXFV12N120P.
