IRGP4760DPBF Equivalent & Substitute Parts

Part Overview

The IRGP4760DPBF is an Infineon Technologies IGBT rated for 650V collector-emitter breakdown voltage with 90A maximum collector current and 325W power dissipation in a Through Hole TO-247-3 package. This device is classified as Obsolete, necessitating identification of functionally equivalent alternatives for ongoing design support and procurement requirements. Substitute parts must maintain electrical compatibility within the specified voltage, current, and thermal operating ranges while accommodating the through-hole mounting configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IRGP4760DPBF is determined by the following critical electrical and mechanical parameters:

Voltage Rating Compatibility: Substitute parts must operate at or above the 650V collector-emitter breakdown voltage specification. The IKW60N60H3FKSA1 operates at 600V, which is below the original specification. However, this device qualifies as a substitute only in applications where the actual operating voltage does not exceed 600V, as the breakdown voltage margin is reduced.

Current Rating Compatibility: The substitute must support the maximum collector current requirement of 90A. The IKW60N60H3FKSA1 is rated for 80A continuous collector current, which is below the original 90A specification. This device is suitable only for applications requiring 80A or less.

Package and Mounting Compatibility: Both devices utilize the TO-247-3 package with Through Hole mounting, ensuring mechanical and thermal interface compatibility.

Operating Temperature Range: Both devices support the -40°C to 175°C junction temperature range, maintaining thermal compatibility.

Compliance and Status: The substitute part is Active product status with ROHS3 compliance, whereas the original is Obsolete. This transition supports long-term supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The IRGP4760DPBF is classified as Obsolete. The IKW60N60H3FKSA1 is Active product status, ensuring continued availability and manufacturing support from Infineon Technologies.

Compliance and Regulatory Status: Both devices maintain REACH Unaffected and EAR99 ECCN classifications, ensuring equivalent regulatory compliance. The IKW60N60H3FKSA1 carries ROHS3 compliance certification, supporting modern environmental standards.

Electrical Parameter Derating: The IKW60N60H3FKSA1 operates at reduced voltage (600V versus 650V) and reduced continuous current (80A versus 90A) ratings. Circuit designs must accommodate these reduced specifications. Applications operating at voltages exceeding 600V or requiring continuous currents above 80A cannot use this substitute without circuit redesign.

Switching Characteristics: The substitute exhibits different switching behavior, including reduced turn-on delay (27ns versus 70ns) and increased turn-off delay (252ns versus 140ns). Gate charge is significantly higher (375nC versus 145nC), requiring gate driver circuit evaluation for compatibility.

Thermal Performance: The IKW60N60H3FKSA1 supports higher maximum power dissipation (416W versus 325W), providing improved thermal headroom in applications within its current and voltage ratings.

Frequently Asked Questions (FAQ)

Q: Can the IKW60N60H3FKSA1 directly replace the IRGP4760DPBF in all applications?

A: No. The substitute operates at 600V maximum breakdown voltage and 80A maximum continuous current, both below the original specifications. Direct replacement is limited to applications where actual operating voltage does not exceed 600V and continuous current does not exceed 80A.

Q: What is the voltage margin difference between these devices?

A: The IRGP4760DPBF provides 650V breakdown voltage, while the IKW60N60H3FKSA1 provides 600V. This represents a 50V reduction in voltage margin. Applications operating near the original 650V specification cannot use the substitute without circuit modification.

Q: Are the switching characteristics compatible?

A: The devices exhibit different switching delays. The IKW60N60H3FKSA1 has faster turn-on (27ns versus 70ns) but slower turn-off (252ns versus 140ns). Gate charge is significantly higher (375nC versus 145nC). Gate driver circuits must be evaluated for compatibility with these characteristics.

Q: Do both devices use the same package?

A: Yes. Both devices use the TO-247-3 package with Through Hole mounting, ensuring mechanical and thermal interface compatibility.

Q: What is the current rating difference?

A: The IRGP4760DPBF supports 90A continuous collector current, while the IKW60N60H3FKSA1 supports 80A. The substitute cannot be used in applications requiring continuous currents above 80A.

Q: Are there compliance differences?

A: Both devices maintain REACH Unaffected and EAR99 classifications. The IKW60N60H3FKSA1 carries ROHS3 compliance, while the original IRGP4760DPBF compliance status is not specified. The substitute supports modern environmental standards.

Q: What is the product status difference?

A: The IRGP4760DPBF is Obsolete, while the IKW60N60H3FKSA1 is Active. The Active status ensures continued manufacturing support and supply chain availability from Infineon Technologies.

Q: Can the higher power rating of the substitute improve thermal performance?

A: The IKW60N60H3FKSA1 supports 416W maximum power dissipation versus 325W for the original. However, this advantage applies only within the substitute's reduced voltage and current ratings. Applications must operate within both the 600V voltage limit and 80A current limit to benefit from improved thermal performance.
