STGW50H60DF IGBT Equivalent & Substitute Parts

Part Overview

The STGW50H60DF is a Trench Field Stop IGBT manufactured by STMicroelectronics, rated for 600V collector-emitter breakdown voltage and 100A continuous collector current with a maximum power dissipation of 360W. The device is packaged in a Through Hole TO-247-3 configuration and is classified as Obsolete product status. Due to its obsolete classification, equivalent substitute parts from active product lines are necessary for new designs and ongoing production requirements. Substitute parts must maintain electrical compatibility within the specified voltage, current, and thermal operating ranges while accommodating the Through Hole TO-247 package format.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the STGW50H60DF is determined by the following critical parameters:

Voltage Compatibility: Substitute parts must have a Collector-Emitter Breakdown Voltage (BVCES) rating equal to or greater than 600V to ensure safe operation within the original circuit design envelope.

Current Capability: Substitute parts must support a continuous collector current (Ic) rating of at least 100A to handle the design load without thermal stress or performance degradation.

Power Dissipation: Substitute parts must have a maximum power rating of at least 360W to accommodate thermal requirements in the application.

Package Compatibility: All substitute parts must utilize the Through Hole TO-247-3 package format to ensure mechanical and electrical compatibility with existing PCB layouts and thermal management solutions.

Thermal Operating Range: Substitute parts must support the junction temperature range of -55°C to 150°C minimum to maintain functionality across the intended operating environment.

Compliance: All substitute parts must maintain ROHS3 compliance and REACH unaffected status to satisfy regulatory and supply chain requirements.

The following substitute parts meet these criteria:

• STGW60H65DFB (STMicroelectronics): Active product with higher voltage rating (650V) and comparable current handling (80A), suitable for applications with elevated voltage margins.
• AOK50B60D1 (Alpha & Omega Semiconductor): Matches 600V/100A specifications but classified as Not For New Designs; available for legacy system support.
• IXXH50N60B3 (IXYS): Exceeds current specification (120A) with enhanced power rating (600W), suitable for high-performance applications.
• NGTB45N60S2WG (onsemi): Lower current rating (45A) limits direct substitution to reduced-load applications only.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute - STGW60H65DFB: This STMicroelectronics part is classified as Active product status and maintains ROHS3 compliance. The 650V voltage rating provides enhanced margin above the original 600V specification, and the 375W power rating closely matches the 360W requirement. The extended operating temperature range to 175°C offers improved thermal headroom. This part is recommended for new designs requiring direct replacement of the obsolete STGW50H60DF.

Secondary Substitute - IXXH50N60B3: This IXYS part is classified as Active product status with ROHS3 compliance. The 120A continuous current rating exceeds the 100A specification, and the 600W power rating provides substantial thermal margin. This part is suitable for applications where enhanced performance and thermal capacity are beneficial, though it represents a higher-specification alternative.

Legacy Support - AOK50B60D1: This Alpha & Omega Semiconductor part matches the 600V/100A electrical specifications exactly but is classified as Not For New Designs. This part is available for sustaining production of existing designs but should not be selected for new development.

Limited Application - NGTB45N60S2WG: This onsemi part is classified as Active product status with ROHS3 compliance. The 45A continuous current rating is insufficient for direct substitution in applications requiring the full 100A specification. This part is suitable only for reduced-load applications or where current requirements do not exceed 45A.

Frequently Asked Questions (FAQ)

Q: Can the STGW60H65DFB directly replace the STGW50H60DF in existing designs?

A: The STGW60H65DFB is mechanically and electrically compatible with the STGW50H60DF. Both devices use the TO-247-3 package and share the same Through Hole mounting configuration. The 650V voltage rating of the STGW60H65DFB is compatible with 600V circuit designs. However, the reduced continuous current rating (80A versus 100A) must be verified against application load requirements. The slightly higher Vce(on) value (2V versus 1.8V) results in marginally increased power dissipation that should be evaluated in thermal analysis.

Q: What is the primary reason for substituting the STGW50H60DF?

A: The STGW50H60DF is classified as Obsolete product status, indicating that STMicroelectronics has discontinued manufacturing and support. Substitute parts from active product lines ensure long-term supply availability, ongoing technical support, and compliance with current manufacturing standards.

Q: Does the IXXH50N60B3 require PCB layout modifications?

A: The IXXH50N60B3 uses the TO-247-3 package format identical to the STGW50H60DF and requires no PCB layout modifications. The Through Hole mounting configuration and pin assignments are compatible. The enhanced power rating (600W versus 360W) may allow for improved thermal performance without design changes.

Q: Why is the NGTB45N60S2WG listed as a substitute if it has lower current rating?

A: The NGTB45N60S2WG is listed as a substitute option for applications where the continuous collector current requirement is 45A or less. This part is not suitable for designs requiring the full 100A specification of the original STGW50H60DF. Verification of actual application current requirements is necessary before selecting this part.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all listed substitute parts (STGW60H65DFB, AOK50B60D1, IXXH50N60B3, and NGTB45N60S2WG) are ROHS3 compliant and REACH unaffected, maintaining regulatory compliance with current environmental and supply chain standards.

Q: What is the impact of higher Vce(on) values in substitute parts?

A: Higher Vce(on) values result in increased power dissipation at the same collector current. For example, the AOK50B60D1 has a Vce(on) of 2.4V compared to 1.8V for the STGW50H60DF. This 0.6V difference increases power loss and requires thermal management verification. Applications with tight thermal budgets should prioritize substitutes with lower Vce(on) values, such as the IXXH50N60B3 (1.8V).

Q: Can the STGW60H65DFB be used in applications with voltage transients exceeding 600V?

A: The STGW60H65DFB has a Collector-Emitter Breakdown Voltage rating of 650V, which provides a 50V margin above the original 600V specification. This margin accommodates typical voltage transients in switching applications. However, circuit protection and snubber design must still be verified to ensure transient voltages remain within the 650V rating.
