IXGH38N60 IGBT Equivalent & Substitute Parts

Part Overview

The IXGH38N60 is a 600V, 76A IGBT manufactured by IXYS in a Through Hole TO-247AD package. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and production continuity. The IXGH38N60 operates within a junction temperature range of -55°C to 150°C and is suitable for high-voltage switching applications requiring moderate current handling and thermal dissipation up to 200W.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IXGH38N60 is determined by the following critical parameters:

Voltage Rating: All substitute parts must maintain a minimum Collector-Emitter breakdown voltage of 600V. Parts rated at 650V are acceptable as they provide voltage margin compatibility.

Current Rating: Substitute parts must support a minimum continuous collector current (Ic) equal to or exceeding 76A. Parts rated at 80A satisfy this requirement with operational headroom.

Package Compatibility: All substitutes must use the TO-247-3 Through Hole package to ensure mechanical and thermal interface compatibility with existing PCB designs.

Input Type: All parts maintain Standard input type configuration, ensuring gate drive circuit compatibility.

Thermal Operating Range: Substitute parts must support the full operating temperature range of -55°C to 150°C minimum. Parts rated to 175°C provide extended thermal margin.

The three substitute parts identified—FGH40N60SMD-F085, NGTB40N60L2WG, and STGW40H65DFB—meet these core substitution criteria while offering enhanced performance characteristics in switching energy and gate charge specifications.

Parameter Comparison

Engineering Selection Recommendations

FGH40N60SMD-F085 (onsemi): This part is classified as Active product status with AEC-Q101 automotive qualification. It provides the lowest switching delay times (18ns on, 110ns off) and operates across an extended temperature range to 175°C. The part is ROHS3 compliant. This substitute is suitable for applications requiring improved switching performance and long-term supply availability.

NGTB40N60L2WG (onsemi): This part is classified as Obsolete, similar to the IXGH38N60. While it meets voltage and current requirements with higher pulsed current capability (160A), its obsolete status provides no advantage for long-term design support. This part is ROHS3 compliant and operates to 175°C.

STGW40H65DFB (STMicroelectronics): This part is classified as Active product status with the highest inventory availability (6560 units). It provides a 650V voltage rating, offering additional voltage margin. The part features balanced switching characteristics (40ns on, 142ns off) and is ROHS3 compliant with extended temperature operation to 175°C. This substitute is recommended for applications requiring maximum supply continuity and voltage headroom.

For new designs and production continuity, FGH40N60SMD-F085 or STGW40H65DFB are preferred due to Active product status and established supply chains.

Frequently Asked Questions (FAQ)

Q: Can the IXGH38N60 be directly replaced with any of these substitutes?

A: Yes, all three substitute parts meet the core electrical and mechanical requirements. All maintain 600V or higher voltage ratings, support 76A or greater continuous current, and use the TO-247-3 Through Hole package. PCB layout and thermal management design remain compatible without modification.

Q: What is the difference between the substitute parts?

A: The primary differences are manufacturer, product status, and performance characteristics. FGH40N60SMD-F085 offers the fastest switching times. NGTB40N60L2WG provides the highest pulsed current capability but is obsolete. STGW40H65DFB offers the highest voltage rating and best supply availability.

Q: Why is product status important for selection?

A: Active product status indicates ongoing manufacturing and supply availability. FGH40N60SMD-F085 and STGW40H65DFB are Active, ensuring long-term procurement viability. NGTB40N60L2WG is Obsolete, presenting potential future supply constraints.

Q: Are there thermal considerations when substituting?

A: All substitutes support the IXGH38N60 operating temperature range of -55°C to 150°C. The substitutes extend operation to 175°C, providing additional thermal margin. Thermal design calculations based on maximum power dissipation should account for the higher power ratings of the substitutes (283W to 417W versus 200W).

Q: Do the substitutes require different gate drive circuits?

A: All parts maintain Standard input type configuration. Gate charge values differ (125nC original versus 180-228nC substitutes), which may require gate drive circuit evaluation for switching speed optimization, but direct compatibility is maintained.

Q: What compliance certifications apply to these parts?

A: All parts are REACH Unaffected and ROHS3 compliant. FGH40N60SMD-F085 carries AEC-Q101 automotive qualification, suitable for automotive and industrial applications requiring formal qualification.

Q: Is the TO-247-3 package identical across all parts?

A: Yes, all parts use the TO-247-3 Through Hole package with identical mechanical dimensions and pin configuration, ensuring direct PCB compatibility without layout modification.
