IRGS4620DPBF IGBT 600V 32A Equivalent & Substitute Parts

Part Overview

The IRGS4620DPBF is a 600V, 32A IGBT manufactured by Infineon Technologies in D2PAK surface mount packaging. This component is classified as obsolete product status. Due to its obsolete designation, locating equivalent substitute parts with compatible electrical and mechanical specifications is necessary for ongoing design support and production continuity. Substitute parts must maintain compatibility across voltage rating, current capacity, package type, and thermal operating range to ensure functional equivalence in circuit applications.

Substitute Part Grouping Explanation

Substitute parts for the IRGS4620DPBF are selected based on the following critical parameters that define functional equivalence:

Voltage Rating: All substitute parts must maintain the 600V collector-emitter breakdown voltage specification to ensure safe operation within the same circuit voltage domain.

Current Capacity: Substitute parts must support minimum 32A collector current (Ic Max) to handle the design current requirements. Parts with higher current ratings provide additional design margin.

Package Compatibility: All substitutes must use TO-263-3 D2PAK surface mount packaging to ensure mechanical and thermal interface compatibility with existing PCB layouts and thermal management solutions.

Operating Temperature Range: Substitute parts must support the -40°C to 175°C junction temperature operating window or equivalent range to maintain reliability across the intended application environment.

Input Type: Standard input type configuration must be maintained for gate drive circuit compatibility.

The two qualified substitute parts meet these criteria while offering active product status and improved availability compared to the obsolete IRGS4620DPBF.

Engineering Selection Recommendations

IKB20N60TATMA1 (Infineon Technologies - Active Status)

This substitute part is manufactured by the same supplier as the original IRGS4620DPBF, ensuring design continuity and technical support alignment. The IKB20N60TATMA1 exceeds the minimum current specification at 40A versus 32A, providing additional design margin. The part is actively produced and widely available (3372 pcs in stock). It carries ROHS3 compliance certification and maintains REACH unaffected status. The TrenchStop® technology designation indicates advanced IGBT architecture. Operating temperature range matches the original specification at -40°C to 175°C.

STGB19NC60KDT4 (STMicroelectronics - Active Status)

This substitute part is actively produced by STMicroelectronics with significantly higher inventory availability (25300 pcs in stock). The STGB19NC60KDT4 meets the 600V voltage and 35A current requirements with margin above the original 32A specification. ROHS3 compliance and REACH unaffected status are confirmed. The PowerMESH™ series designation indicates modern IGBT technology. Operating temperature range extends to -55°C minimum, exceeding the original -40°C specification. Cut Tape and Digi-Reel® packaging options provide flexible procurement formats.

Both substitute parts maintain TO-263-3 D2PAK package compatibility, standard input type configuration, and surface mount mounting type. Selection between these two options depends on supplier preference, inventory requirements, and specific application thermal or switching performance needs.

Frequently Asked Questions (FAQ)

Q: Can the IKB20N60TATMA1 or STGB19NC60KDT4 be used as direct replacements for the IRGS4620DPBF in existing designs?

A: Both substitute parts maintain the same 600V voltage rating, TO-263-3 D2PAK package, surface mount configuration, and standard input type. Both exceed the minimum 32A current requirement. PCB layout compatibility is maintained due to identical package geometry. Gate drive circuits designed for standard input type IGBTs are compatible with both substitutes.

Q: What are the key differences between the two substitute options?

A: The IKB20N60TATMA1 is manufactured by Infineon Technologies (original supplier) with 40A current rating and TrenchStop® technology. The STGB19NC60KDT4 is manufactured by STMicroelectronics with 35A current rating, PowerMESH™ technology, and significantly higher inventory availability. The STGB19NC60KDT4 has lower reverse recovery time (31 ns vs 41 ns) and extended minimum operating temperature (-55°C vs -40°C).

Q: Are there any thermal management considerations when substituting these parts?

A: The IKB20N60TATMA1 has higher maximum power rating (166W vs 140W original), while the STGB19NC60KDT4 has lower maximum power rating (125W vs 140W original). Both parts use identical TO-263-3 D2PAK packaging with the same thermal interface characteristics. Thermal management solutions designed for the original part remain applicable to both substitutes.

Q: Do both substitute parts meet regulatory compliance requirements?

A: Both substitute parts carry ROHS3 compliance certification and REACH unaffected status, matching or exceeding the regulatory profile of the original IRGS4620DPBF. Both parts have MSL rating of 1 (Unlimited) for moisture sensitivity.

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

A: The original IRGS4620DPBF has 25 nC gate charge. The IKB20N60TATMA1 has 120 nC and the STGB19NC60KDT4 has 55 nC. Higher gate charge requires proportionally higher gate drive current to achieve specified switching times. Gate drive circuits must be evaluated for compatibility with the selected substitute part's gate charge specification.

Q: How do switching time differences affect application performance?

A: The original part specifies 31ns on-time and 83ns off-time. The IKB20N60TATMA1 has 18ns on-time and 199ns off-time. The STGB19NC60KDT4 has 30ns on-time and 105ns off-time. Switching time differences impact EMI characteristics and power loss profiles. Applications with strict switching frequency or EMI requirements should evaluate these parameters against design specifications.
