Key Parameters

Substitute Part Grouping Explanation

Substitution of the IXTH220N075T is determined by the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

• Drain to Source Voltage (Vdss): 75V minimum
• Continuous Drain Current (Id): 220A or greater at 25°C
• Package Type: TO-247 form factor (TO-247-3, TO-247AC, or TO-247AD variants acceptable)
• Operating Temperature Range: -55°C to 175°C minimum
• Gate Drive Voltage: 10V
• Maximum Gate Voltage (Vgs): ±20V

Secondary Compatibility Parameters:

• On-State Resistance (Rds On): Lower or equivalent values indicate improved performance
• Gate Charge (Qg): Lower values reduce switching losses
• Input Capacitance (Ciss): Lower values reduce gate drive requirements
• Power Dissipation: 480W or greater supports thermal equivalence

Substitute parts are grouped into two categories: Direct Equivalents (matching or exceeding all primary criteria) and Functional Alternatives (meeting primary criteria with trade-offs in secondary parameters).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Preferred):

IXFH230N075T2 is the primary substitute for IXTH220N075T. This part maintains the same 75V voltage rating and exceeds the 220A current requirement with 230A continuous drain current. The IXFH230N075T2 is manufactured by IXYS, the same supplier as the original part, ensuring design continuity. This device is Active in product status and ROHS3 Compliant, providing long-term availability and regulatory compliance. The on-state resistance of 4.2 mOhm at 50A, 10V is superior to the original specification, resulting in lower conduction losses. The TO-247AD package variant is mechanically compatible with TO-247-3 applications.

Secondary Equivalent (High Current Capability):

IRFP2907PBF from Infineon Technologies meets the 75V voltage requirement and provides 209A continuous drain current, closely matching the original 220A specification. This part is Active in product status and ROHS3 Compliant. The on-state resistance of 4.5 mOhm at 125A, 10V is equivalent to the original part. However, the gate charge of 620 nC at 10V is significantly higher than the original 165 nC, resulting in increased gate drive power requirements. The TO-247AC package is mechanically compatible with TO-247-3 applications.

Functional Alternative (Lower Current Rating):

IRFP3077PBF from Infineon Technologies maintains the 75V voltage rating but provides only 120A continuous drain current, representing a 45% reduction from the original 220A specification. This part is suitable only for applications where the current requirement does not exceed 120A. The on-state resistance of 3.3 mOhm at 75A, 10V is superior to the original specification. The gate charge of 220 nC at 10V is higher than the original but lower than IRFP2907PBF. This part is Active in product status and ROHS3 Compliant.

Not Recommended:

IRFP3306PBF has a reduced voltage rating of 60V, which is below the original 75V specification and does not meet the primary substitution criterion. This part is not suitable for applications requiring the full 75V capability.

FDH210N08 from onsemi meets the 75V voltage requirement and provides 210A continuous drain current, closely matching the original specification. However, critical electrical parameters including on-state resistance, gate threshold voltage, gate charge, and input capacitance are not specified in the provided data, preventing complete electrical equivalence verification. This part is Active in product status and ROHS3 Compliant.

Frequently Asked Questions (FAQ)

Q: Can IXFH230N075T2 be used as a direct replacement for IXTH220N075T?

A: Yes. IXFH230N075T2 meets all primary substitution criteria: 75V voltage rating, 230A continuous drain current (exceeding the original 220A), TO-247 package compatibility, and identical operating temperature range. The part is manufactured by IXYS and is Active in product status, ensuring long-term availability.

Q: What is the significance of the higher gate charge in IRFP2907PBF compared to IXTH220N075T?

A: Gate charge (Qg) determines the energy required to switch the MOSFET on and off. IRFP2907PBF has a gate charge of 620 nC at 10V, compared to 165 nC for IXTH220N075T. This 3.76x increase requires proportionally higher gate drive current or longer switching times, potentially increasing switching losses and reducing maximum switching frequency in the application circuit.

Q: Are TO-247AC and TO-247AD packages mechanically interchangeable with TO-247-3?

A: Yes. TO-247AC and TO-247AD are mechanical variants of the TO-247-3 package. All three variants have identical pin configurations and mounting hole patterns, allowing direct mechanical substitution on printed circuit boards designed for TO-247-3 devices.

Q: Why is IRFP3306PBF not recommended as a substitute?

A: IRFP3306PBF has a maximum drain-to-source voltage (Vdss) of 60V, which is below the original IXTH220N075T specification of 75V. Using this part in a circuit designed for 75V operation would result in device failure or reduced reliability. This part does not meet the primary substitution criterion for voltage rating.

Q: What is the impact of lower on-state resistance in substitute parts?

A: Lower on-state resistance (Rds On) reduces conduction losses during the on-state, resulting in lower heat generation and improved efficiency. For example, IRFP3077PBF has 3.3 mOhm compared to the original 4.5 mOhm, reducing resistive losses by approximately 27% at equivalent current levels. This improvement is beneficial for thermal management and overall system efficiency.

Q: Can FDH210N08 be used if electrical parameters are not fully specified?

A: FDH210N08 meets the voltage and current requirements based on available data. However, the absence of specified values for on-state resistance, gate threshold voltage, gate charge, and input capacitance prevents complete electrical equivalence verification. Use of this part requires obtaining complete electrical specifications from the manufacturer or conducting application-specific testing to confirm compatibility.

Q: What does ROHS3 Compliance indicate?

A: ROHS3 Compliance indicates that the part meets the Restriction of Hazardous Substances Directive 3, which restricts the use of specific hazardous materials in electrical and electronic equipment. All active substitute parts listed are ROHS3 Compliant, ensuring regulatory compliance for new designs and procurement.

Q: Is the IXTH220N075T still available for procurement?

A: IXTH220N075T is classified as Obsolete. While 784 pieces are listed as in stock, long-term availability is not guaranteed. Substitution with an Active product status part such as IXFH230N075T2 is recommended for new designs and ongoing production to ensure supply chain continuity.
