Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IXGR32N60C is determined by the following critical parameters:

Voltage Compatibility: All substitute parts must maintain a Collector-Emitter breakdown voltage rating of 600V to ensure safe operation within the original circuit design envelope.

Current Rating: Substitute parts must support a continuous collector current (Ic) rating of at least 45A. Parts with higher current ratings (40A minimum) are acceptable as they provide equivalent or superior current handling capacity.

Power Dissipation: The substitute must support a maximum power rating of at least 140W to accommodate thermal design requirements.

Package and Mounting: Substitute parts must use through-hole mounting in compatible packages. TO-247-3 packages are directly compatible with the original ISOPLUS247™ footprint.

Operating Temperature: Substitute parts must support the operating temperature range of -55°C to 150°C (TJ) or higher.

Input Type: Standard input type configuration is required for gate drive compatibility.

The following substitute parts meet these criteria:

• STGW40H60DLFB (STMicroelectronics): 600V, 80A, 283W, TO-247-3, Active status
• STGW19NC60HD (STMicroelectronics): 600V, 42A, 140W, TO-247-3, Active status
• STGW20V60DF (STMicroelectronics): 600V, 40A, 167W, TO-247-3, Active status
• STGFW20V60DF (STMicroelectronics): 600V, 40A, 52W, TO-3PF, Obsolete status

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: STGW19NC60HD

The STGW19NC60HD is the optimal substitute for the IXGR32N60C. This part maintains electrical equivalence across all critical parameters: 600V voltage rating, 42A continuous current (within 7A of the original 45A), and 140W power dissipation (exact match). The TO-247-3 package provides direct mechanical compatibility with the original ISOPLUS247™ footprint. The STGW19NC60HD carries Active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment. Operating temperature range extends to 150°C, matching the original specification. Gate charge of 53nC is lower than the original 110nC, resulting in improved switching efficiency.

Secondary Recommendation: STGW20V60DF

The STGW20V60DF provides an alternative with enhanced power handling (167W versus 140W) and improved thermal performance (175°C operating range). The 40A continuous current rating is 5A below the original specification but remains within acceptable margins for most applications. This part is Active status with ROHS3 compliance. The TO-247-3 package ensures mechanical compatibility. Lower Vce(on) (2.2V versus 2.7V) reduces conduction losses.

Tertiary Recommendation: STGW40H60DLFB

The STGW40H60DLFB is suitable for applications requiring higher current capacity (80A continuous, 160A pulsed). This part delivers superior power dissipation (283W) and extended operating temperature range (175°C). Active product status with ROHS3 compliance ensures availability. The TO-247-3 package maintains mechanical compatibility. Higher gate charge (210nC) and longer turn-off delay (142ns) require gate drive circuit evaluation. This part is appropriate for designs with thermal margin and gate drive capability for higher capacitive loads.

Not Recommended: STGFW20V60DF

The STGFW20V60DF is classified as Obsolete, presenting the same long-term availability risk as the original IXGR32N60C. Additionally, the 52W power rating is substantially below the 140W requirement, making this part unsuitable for equivalent thermal design. The TO-3PF package differs from the original TO-247-3, requiring PCB layout modification.

Frequently Asked Questions (FAQ)

Q: Can the STGW19NC60HD directly replace the IXGR32N60C without circuit modifications?

A: The STGW19NC60HD is electrically compatible with the IXGR32N60C across voltage, current, and power specifications. Both parts use TO-247-3 packages with identical pin configurations and standard input type gate drive. Direct substitution is supported without circuit modifications. The lower gate charge (53nC versus 110nC) may improve switching performance in existing gate drive circuits.

Q: What is the significance of the 42A versus 45A current rating difference?

A: The STGW19NC60HD provides 42A continuous current capacity compared to the original 45A. This 3A difference (6.7% margin reduction) is acceptable for most applications operating below the original 45A design point. Applications operating at or near 45A continuous current should evaluate thermal performance with the substitute part to confirm adequate margin.

Q: Why does the STGW40H60DLFB have a higher gate charge than the original part?

A: The STGW40H60DLFB (210nC) has higher gate charge than the IXGR32N60C (110nC) due to its higher current rating (80A versus 45A). Higher current capacity requires larger silicon die area, resulting in increased gate capacitance. Gate drive circuits must supply sufficient current to charge this capacitance within acceptable switching time windows. Existing gate drive circuits should be evaluated for compatibility with the higher gate charge specification.

Q: Are all substitute parts ROHS3 compliant?

A: The three Active substitute parts (STGW19NC60HD, STGW20V60DF, STGW40H60DLFB) are ROHS3 compliant. The STGFW20V60DF (Obsolete) does not specify RoHS status. All parts carry REACH Unaffected designation. For applications requiring regulatory compliance documentation, the Active parts with ROHS3 certification are preferred.

Q: What is the difference between the TO-247-3 and TO-3PF packages?

A: The TO-247-3 is a standard through-hole package with three leads (Collector, Gate, Emitter) in a rectangular configuration. The TO-3PF is a full-pack variant with different lead geometry and spacing. These packages are not mechanically interchangeable and require different PCB footprints. The STGFW20V60DF uses TO-3PF, while the IXGR32N60C and recommended substitutes use TO-247-3.

Q: How do switching energy specifications affect circuit performance?

A: Switching energy (measured in µJ) represents energy dissipated during turn-on and turn-off transitions. The IXGR32N60C specifies 320µJ off-switching energy. The STGW19NC60HD specifies 189µJ off-switching energy, indicating lower switching losses. Lower switching energy reduces thermal stress and improves efficiency in high-frequency applications. The STGW40H60DLFB specifies 363µJ off-switching energy, reflecting its higher current rating and larger die size.

Q: Can the STGW40H60DLFB be used in applications designed for 45A operation?

A: The STGW40H60DLFB (80A rating) can be used in 45A applications. The higher current rating provides additional thermal margin and reliability. However, the higher gate charge (210nC) and longer turn-off delay (142ns) require gate drive circuit evaluation. Existing gate drive circuits designed for the IXGR32N60C (110nC gate charge) must confirm adequate current sourcing capability for the higher capacitive load. Switching frequency and thermal performance should be validated in the target application.

Q: What is the operating temperature significance of the 150°C versus 175°C range?

A: The IXGR32N60C specifies -55°C to 150°C (TJ) operating range. The STGW19NC60HD matches this specification exactly. The STGW20V60DF and STGW40H60DLFB extend to 175°C, providing 25°C additional thermal margin. Extended temperature range allows operation in higher ambient or higher power dissipation conditions. Applications with tight thermal budgets benefit from the extended range of the STMicroelectronics alternatives.

Q: Is the STGFW20V60DF a viable substitute despite its Obsolete status?

A: The STGFW20V60DF is not recommended as a substitute. Although it carries the same Obsolete status as the original IXGR32N60C, it introduces additional obsolescence risk without providing functional improvement. The 52W power rating is substantially below the 140W requirement, creating thermal design incompatibility. The TO-3PF package differs from the original TO-247-3, requiring PCB redesign. Active alternatives (STGW19NC60HD, STGW20V60DF, STGW40H60DLFB) provide superior long-term availability and regulatory compliance.
