IXGH28N60B IGBT 600V 40A 150W Equivalent & Substitute Parts

Part Overview

The IXGH28N60B is an IGBT (Insulated Gate Bipolar Transistor) manufactured by IXYS, rated for 600V collector-emitter breakdown voltage and 40A maximum collector current with 150W power dissipation capability. The device is packaged in a Through Hole TO-247AD configuration and is classified as obsolete. Due to its obsolete product status, equivalent and substitute parts from active manufacturers are necessary to maintain design continuity and ensure long-term component availability for new production runs and system upgrades.

Substitute Part Grouping Explanation

Substitution of the IXGH28N60B is determined by the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

Voltage rating: 600V collector-emitter breakdown voltage (minimum requirement)
Current rating: 40A maximum collector current (minimum requirement)
Package type: Through Hole TO-247-3 or compatible footprint
Input type: Standard gate drive compatibility
Operating temperature range: Minimum -55°C to 150°C junction temperature

Substitution Categories:

Direct Substitutes maintain identical or superior electrical specifications within the same voltage and current class, allowing pin-for-pin replacement with no circuit modifications.

Similar Substitutes meet the core voltage and current requirements but may differ in secondary parameters such as power dissipation capability, switching characteristics, or gate charge. These parts are functionally compatible but require verification of thermal management and switching performance in the target application.

Parts that exceed the 40A current rating (such as IXGH36N60B3 at 92A) are suitable for applications where higher current capability provides design margin, provided thermal management is adequate.

Engineering Selection Recommendations

For Direct Replacement (Pin-Compatible):

The IXGH36N60B3 from IXYS is the primary direct substitute. It maintains the same manufacturer lineage and TO-247-3 package, with superior electrical performance (92A vs. 40A, 250W vs. 150W). The part is Active status with ROHS3 compliance, ensuring long-term availability. The lower Vce(on) (1.8V vs. 2V) and faster switching times (19/125ns vs. 15/175ns) provide improved efficiency. This part is suitable for applications requiring higher current margin or improved thermal performance.

For Equivalent Functionality (Same Voltage/Current Class):

The IKW20N60H3FKSA1 and IKW20N60TFKSA1 from Infineon Technologies are functionally equivalent at the 600V/40A specification. Both are Active status with ROHS3 compliance and extended operating temperature range (-40 to 175°C). These Trench Field Stop technology devices provide alternative sourcing from a major manufacturer. The IKW20N60TFKSA1 offers lower Vce(on) (2.05V vs. 2.4V) and faster reverse recovery (41ns vs. 112ns).

The STGW20V60DF from STMicroelectronics matches the 600V/40A specification in TO-247-3 package with Active status and ROHS3 compliance. Extended operating temperature range (-55 to 175°C) matches the original part's lower temperature limit. Power rating of 167W is within acceptable margin of the original 150W specification.

For Higher Current Applications:

The STGW40H60DLFB provides 80A current capability (double the original 40A) in the same 600V voltage class and TO-247-3 package. Active status with ROHS3 compliance ensures availability. This part is suitable for applications where current margin or thermal headroom is required.

Compliance and Availability:

All recommended substitute parts are Active status products with ROHS3 compliance, ensuring regulatory compliance and long-term manufacturing support. The IXGH28N60B's Obsolete status necessitates transition to one of these Active alternatives for new designs and production continuity.

Frequently Asked Questions (FAQ)

Q: Can the IXGH36N60B3 directly replace the IXGH28N60B in existing designs?

A: Yes. The IXGH36N60B3 maintains identical TO-247-3 package pinout and Standard input type gate drive compatibility. The higher current rating (92A vs. 40A) and improved switching characteristics provide superior performance without circuit modification. Thermal management design should account for the higher power dissipation capability (250W vs. 150W).

Q: What is the difference between the Infineon IKW20N60H3FKSA1 and IKW20N60TFKSA1?

A: Both devices are 600V/40A Trench Field Stop IGBTs in TO-247-3 package with identical gate charge (120nC). The IKW20N60TFKSA1 features lower Vce(on) (2.05V vs. 2.4V) and significantly faster reverse recovery time (41ns vs. 112ns), resulting in lower switching losses. The IKW20N60H3FKSA1 provides extended operating temperature range specification (-40 to 175°C vs. unspecified for TFKSA1).

Q: Are the STMicroelectronics STGW20V60DF and STGW40H60DLFB interchangeable?

A: Both are 600V Trench Field Stop IGBTs in TO-247-3 package with Active status and ROHS3 compliance. The STGW20V60DF is rated for 40A continuous current (matching the original IXGH28N60B), while the STGW40H60DLFB is rated for 80A. The STGW40H60DLFB is not a direct replacement due to higher current rating and gate charge (210nC vs. 116nC), which affects gate drive circuit requirements. Selection depends on application current requirements.

Q: What is the impact of higher gate charge on circuit design?

A: Gate charge affects the gate drive circuit's switching speed and power consumption. The IXGH28N60B has 68nC gate charge. Substitute parts range from 80nC (IXGH36N60B3) to 210nC (STGW40H60DLFB). Higher gate charge requires longer gate drive pulse width or higher gate drive current to achieve the same switching speed. Existing gate drive circuits designed for 68nC may require adjustment for parts with significantly higher gate charge (120nC or above).

Q: Can I use a 650V rated IGBT in a 600V application?

A: The STGW30H65FB (650V rating) is not included in the primary substitute list for the IXGH28N60B. While 650V devices can operate in 600V applications, they represent a different voltage class with different electrical characteristics. Use only parts explicitly listed as substitutes for the IXGH28N60B to ensure design compatibility and performance validation.

Q: What is the significance of "Active" vs. "Obsolete" product status?

A: Active status indicates the manufacturer continues production and supports the part with technical documentation and supply chain availability. Obsolete status means the manufacturer has discontinued production. The IXGH28N60B's Obsolete status creates supply risk for new production. All recommended substitutes are Active status, ensuring long-term availability and manufacturer support.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All recommended substitute parts carry ROHS3 Compliant certification. The original IXGH28N60B does not specify RoHS status. Transition to ROHS3 compliant substitutes ensures compliance with current environmental regulations and procurement requirements.

Q: What package considerations apply to these substitutes?

A: All substitute parts use Through Hole TO-247-3 package, maintaining identical PCB footprint and mounting compatibility with the original IXGH28N60B. The STGFW20V60DF uses TO-3PF package (different footprint) and is not recommended for direct replacement without PCB redesign.
