IRGPH40F IGBT Equivalent & Substitute Parts

Part Overview

The IRGPH40F is a fast IGBT manufactured by Infineon Technologies, rated for 1200V collector-emitter breakdown voltage and 29A maximum collector current. This component is designed for high-voltage switching applications requiring through-hole mounting in TO-247AC packaging. The part is currently classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IRGPH40F is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - Collector Emitter Breakdown (Max): 1200V minimum
• Package / Case: TO-247-3 form factor
• Mounting Type: Through Hole
• Input Type: Standard
• Operating Temperature Range: -55°C to 150°C or wider

Allowable Variation Parameters:

• Current - Collector (Ic) (Max): Equal to or greater than 29A
• Vce(on) (Max): Equal to or lower than 3.3V at equivalent test conditions
• Power - Max: Equal to or greater than 160W

The IXGH20N120 from IXYS meets all critical matching parameters and demonstrates improved electrical performance characteristics within the allowable variation range.

Engineering Selection Recommendations

IXGH20N120 as Primary Substitute:

The IXGH20N120 is designated as the manufacturer-recommended substitute for the IRGPH40F. This part maintains electrical equivalence across all critical parameters while offering improved on-state voltage performance (2.5V versus 3.3V at comparable test conditions). The IXGH20N120 is classified as Active product status, ensuring continued availability and manufacturer support.

Compliance Considerations:

The IXGH20N120 carries ROHS3 compliance certification, whereas the IRGPH40F is RoHS non-compliant. Both parts are REACH Unaffected and classified under ECCN EAR99. For applications subject to RoHS regulatory requirements, the IXGH20N120 provides compliant operation.

Mechanical Compatibility:

Both components utilize identical TO-247-3 through-hole packaging and TO-247 form factor specifications, enabling direct mechanical substitution without PCB redesign or mechanical rework.

Frequently Asked Questions (FAQ)

Q: Can the IXGH20N120 directly replace the IRGPH40F in existing designs?

A: Yes. The IXGH20N120 maintains identical voltage rating (1200V), operating temperature range (-55 to 150°C), and TO-247-3 package form factor. The higher current rating (40A versus 29A) and lower on-state voltage (2.5V versus 3.3V) represent performance improvements compatible with existing circuit designs.

Q: What is the significance of the higher current rating on the IXGH20N120?

A: The IXGH20N120 is rated for 40A maximum collector current compared to 29A on the IRGPH40F. This higher rating provides additional design margin and does not create incompatibility. The substitute will operate safely in applications designed for the lower current specification.

Q: Are there package differences between these parts?

A: Both parts use TO-247-3 through-hole packaging. The IRGPH40F is supplied in TO-247AC variant, while the IXGH20N120 is supplied in TO-247AD variant. Both variants conform to TO-247-3 mechanical and electrical specifications, enabling direct pin-compatible substitution.

Q: Why is the IRGPH40F classified as obsolete?

A: Obsolete classification indicates the part is no longer manufactured or supported by Infineon Technologies. The IXGH20N120 represents the active alternative for new designs and replacement applications.

Q: Does the IXGH20N120 meet RoHS requirements?

A: Yes. The IXGH20N120 is ROHS3 compliant. The original IRGPH40F is RoHS non-compliant. For applications requiring RoHS compliance, the IXGH20N120 provides a compliant substitute.

Q: What are the switching characteristics of the IXGH20N120?

A: The IXGH20N120 provides switching energy of 6.5mJ (off) and delay times of 28ns (on) and 400ns (off) at 25°C under test conditions of 800V, 20A, 47Ohm, 15V. Gate charge is specified at 63nC.
