IXGP20N60B IGBT Equivalent & Substitute Parts

Part Overview

The IXGP20N60B is a 600V, 40A IGBT manufactured by IXYS in the HiPerFAST™ series, housed in a TO-220-3 through-hole package. This component is classified as obsolete, necessitating identification of active equivalent and substitute parts for new designs and production continuity. The IXGP20N60B delivers 150W maximum power dissipation with switching energy specifications of 150µJ (on) and 700µJ (off), making it suitable for general-purpose switching applications in the 600V class.

Due to its obsolete status, equivalent active parts from Infineon Technologies and STMicroelectronics are available as direct substitutes, maintaining the same voltage and current ratings while offering improved performance characteristics and continued manufacturing support.

Substitute Part Grouping Explanation

Substitution of the IXGP20N60B is determined by strict equivalence in the following critical parameters:

Primary Substitution Criteria:

Voltage - Collector Emitter Breakdown (Max): 600V
Current - Collector (Ic) (Max): 40A
Package / Case: TO-220-3
Mounting Type: Through Hole
Input Type: Standard

Secondary Compatibility Parameters:

Current - Collector Pulsed (Icm): 80A or greater
Vce(on) (Max) @ Vge, Ic: 2V or lower at 15V, 20A
Operating Temperature Range: Must encompass -55°C minimum
Gate Charge: 90nC to 120nC range acceptable

All substitute parts listed maintain the 600V/40A core ratings and TO-220-3 package specification. Variations in switching energy, gate charge, and thermal characteristics reflect different IGBT technology generations (standard vs. Trench Field Stop architectures) but do not preclude functional substitution within the specified electrical envelope.

Engineering Selection Recommendations

Primary Substitutes (Infineon TrenchStop® Series):

The IGP20N60H3XKSA1, IKP20N60H3XKSA1, and IKP20N60TXKSA1 represent active Infineon alternatives with Trench Field Stop technology. All three maintain the 600V/40A electrical specification and TO-220-3 package. These parts are ROHS3 compliant and carry active product status with full manufacturing support. The IKP20N60TXKSA1 offers the lowest Vce(on) at 2.05V, providing superior conduction efficiency compared to the original IXGP20N60B at 2V. All Infineon substitutes extend the upper operating temperature to 175°C, compared to the original 150°C maximum.

Secondary Substitutes (STMicroelectronics Series):

The STGP20H60DF provides the closest electrical match to the IXGP20N60B, with identical Vce(on) of 2V at 15V, 20A and matching 80A pulsed current rating. This part is ROHS3 compliant and active. The STGP19NC60HD operates at lower gate charge (53nC) and reduced switching times but is rated for 12A test current rather than 20A, resulting in higher Vce(on) at 2.5V. Both STMicroelectronics parts maintain the -55°C lower temperature limit of the original device.

Compliance and Availability:

All substitute parts carry REACH Unaffected status and EAR99 ECCN classification, matching the original part's regulatory profile. Moisture Sensitivity Level remains at MSL 1 (Unlimited) across all alternatives. Current inventory levels are substantial across all substitutes, ensuring supply continuity.

Frequently Asked Questions (FAQ)

Q: Can the IGP20N60H3XKSA1 directly replace the IXGP20N60B without circuit modifications?

A: The IGP20N60H3XKSA1 maintains the 600V/40A ratings and TO-220-3 package, enabling direct pin-compatible substitution. The higher Vce(on) of 2.4V versus 2V results in approximately 4% increased conduction losses at 20A. Gate charge increases from 90nC to 120nC, requiring gate driver verification for switching frequency compatibility. Operating temperature range extends to 175°C, providing enhanced thermal margin.

Q: What is the difference between the Infineon Trench Field Stop variants?

A: The IKP20N60H3XKSA1 and IGP20N60H3XKSA1 are electrically identical with 2.4V Vce(on) and 690µJ switching energy. The IKP20N60TXKSA1 offers improved conduction performance at 2.05V Vce(on) with 770µJ switching energy and reduced reverse recovery time of 41ns. Selection depends on whether conduction efficiency or switching speed is prioritized in the application.

Q: Is the STGP19NC60HD suitable for high-current applications?

A: The STGP19NC60HD is rated for 40A continuous collector current, matching the IXGP20N60B specification. However, its test condition is specified at 12A rather than 20A, and pulsed current is limited to 60A versus 80A for the original part. This part is appropriate for applications where gate charge minimization (53nC) and fast switching times are critical, but not for maximum current density operation.

Q: What packaging considerations apply to these substitutes?

A: All substitute parts are housed in TO-220-3 through-hole packages with identical pin configurations to the IXGP20N60B. Tube packaging is standard for Infineon and STMicroelectronics variants. PCB footprint and thermal interface requirements remain unchanged, enabling direct mechanical substitution.

Q: Are there temperature derating requirements when using substitutes with extended operating ranges?

A: The Infineon substitutes extend maximum junction temperature to 175°C compared to the original 150°C. This provides additional thermal margin but does not eliminate derating requirements. Thermal design calculations must account for the specific Vce(on) and switching energy characteristics of the selected substitute to ensure junction temperature remains within specified limits.

Q: Which substitute offers the best overall performance match to the IXGP20N60B?

A: The STGP20H60DF provides the closest electrical performance match with identical 2V Vce(on) at 15V, 20A and matching 80A pulsed current. This STMicroelectronics part maintains the original -55°C lower temperature limit and offers active product status with ROHS3 compliance. Switching energy characteristics (209µJ on, 261µJ off) differ from the original, reflecting modern Trench Field Stop technology.
