IXTH200N075T N-Channel 75V 200A MOSFET Equivalent & Substitute Parts

Part Overview

The IXTH200N075T is an N-Channel MOSFET manufactured by IXYS, rated for 75V drain-to-source voltage and 200A continuous drain current in a TO-247 through-hole package. This device is classified as obsolete product status. Due to its obsolescence, equivalent and substitute parts from active manufacturers are necessary to maintain design continuity and ensure long-term component availability for new production and field replacements.

Substitute Part Grouping Explanation

Substitution eligibility for the IXTH200N075T is determined by the following critical parameters:

Primary Matching Criteria:

Drain-to-Source Voltage (Vdss): Must equal or exceed 75V
Continuous Drain Current (Id): Must meet or exceed 200A at 25°C
Package Type: TO-247 form factor (TO-247-3, TO-247AC, TO-247AD variants acceptable)
Mounting Type: Through-hole configuration
Gate Voltage Rating (Vgs Max): Must support ±20V operation
Operating Temperature Range: Must span -55°C to 175°C minimum

Secondary Compatibility Parameters:

On-State Resistance (Rds On): Lower values indicate improved performance; values within 20% variance are functionally compatible
Gate Charge (Qg): Affects switching speed; higher values acceptable if circuit design accommodates
Input Capacitance (Ciss): Influences gate drive requirements; variance acceptable within circuit design margins
Power Dissipation Rating: Must support thermal requirements of the application

Substitute parts meeting all primary criteria are classified as direct functional equivalents. Parts meeting primary criteria with secondary parameter variations are classified as similar substitutes with application-dependent suitability.

Engineering Selection Recommendations

Direct Functional Equivalents (200A+ Current Rating, 75V Vdss):

IXFH230N075T2, IRFP2907PBF, and FDH210N08 meet all primary substitution criteria for the IXTH200N075T. These parts maintain the 75V voltage rating and deliver continuous drain current at or above 200A. All three are active products with ROHS3 compliance, ensuring long-term availability and regulatory conformance. The IXFH230N075T2 offers enhanced performance with 230A rating and lower Rds On (4.2 mOhm), while IRFP2907PBF provides 209A with established HEXFET® technology. FDH210N08 delivers 210A in standard TO-247-3 packaging.

Secondary Substitutes (Reduced Current Rating, 75V Vdss):

IRFP3077PBF and FDH047AN08A0 operate at 75V but with reduced continuous drain current ratings (120A and 15A respectively). These parts are suitable only for applications where the actual operating current does not exceed their rated specifications. IRFP3077PBF provides a mid-range option with 120A capability and superior Rds On performance (3.3 mOhm). FDH047AN08A0 is limited to 15A operation and is not suitable for high-current applications.

Not Recommended:

IRFP3306PBF operates at 60V Vdss, which is below the 75V requirement of the IXTH200N075T. This part does not meet the primary voltage matching criterion and introduces voltage derating risk in applications designed for 75V operation.

All recommended substitutes maintain the TO-247 package family compatibility, ±20V gate voltage rating, and -55°C to 175°C operating temperature range. Selection between direct equivalents should be based on specific application requirements for current capacity, on-state resistance, and thermal management.

Frequently Asked Questions (FAQ)

Q: Can IRFP3306PBF be used as a substitute for IXTH200N075T?

A: No. IRFP3306PBF is rated for 60V Vdss, which is 15V below the 75V requirement of IXTH200N075T. Using a lower voltage-rated device in a 75V application creates risk of device failure and is not an acceptable substitution.

Q: What is the difference between TO-247-3, TO-247AC, and TO-247AD packages?

A: All three are TO-247 family through-hole packages with identical electrical pin configurations and mechanical compatibility. TO-247-3 is the standard variant. TO-247AC and TO-247AD are manufacturer-specific designations with minor mechanical variations that do not affect electrical performance or PCB mounting. Devices in any of these variants are mechanically and electrically interchangeable.

Q: Is IRFP2907PBF a direct replacement for IXTH200N075T?

A: Yes. IRFP2907PBF meets all primary substitution criteria: 75V Vdss, 209A continuous drain current (exceeds 200A requirement), TO-247AC package (compatible with TO-247-3), ±20V gate voltage, and -55°C to 175°C operating range. IRFP2907PBF is an active product with ROHS3 compliance.

Q: Why does IXFH230N075T2 have higher gate charge (178 nC) than IXTH200N075T (160 nC)?

A: Gate charge variation reflects differences in internal device structure and switching characteristics between manufacturers and product generations. The 178 nC specification for IXFH230N075T2 is within acceptable variance for functional substitution. Gate drive circuits designed for the original part will operate the substitute part; however, switching speed may differ slightly. This does not prevent substitution in most applications.

Q: Can FDH047AN08A0 be used in place of IXTH200N075T?

A: No. FDH047AN08A0 is rated for only 15A continuous drain current, which is significantly below the 200A requirement of IXTH200N075T. This part is suitable only for low-current applications and cannot support the current demands of circuits designed for 200A operation.

Q: What does "Product Status: Obsolete" mean for IXTH200N075T?

A: Obsolete status indicates that IXYS has discontinued manufacturing and support for this part. New inventory may be available from distributors, but long-term supply cannot be guaranteed. For new designs and future production, selection of an active substitute part (IXFH230N075T2, IRFP2907PBF, or FDH210N08) is necessary to ensure component availability.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All recommended substitute parts (IXFH230N075T2, IRFP2907PBF, FDH210N08, IRFP3077PBF, and FDH047AN08A0) are ROHS3 compliant. The original IXTH200N075T does not specify RoHS status. ROHS3 compliance ensures the parts meet current environmental and regulatory requirements for manufacturing and distribution.

Q: What is the significance of Rds On (on-state resistance) in selecting a substitute?

A: Rds On determines power dissipation during device operation. Lower Rds On values result in reduced heat generation and improved efficiency. Substitute parts with lower Rds On (such as IRFP3077PBF at 3.3 mOhm) provide performance benefits. However, higher Rds On values within reasonable variance are functionally acceptable if the circuit design and thermal management accommodate the increased power dissipation.

Q: Can substitute parts be mixed in the same circuit or application?

A: Mixing different substitute parts in parallel or in the same application is not recommended without detailed circuit analysis. Differences in Rds On, gate charge, and input capacitance can result in unequal current sharing or switching timing mismatches. If multiple devices are required, use identical part numbers to ensure consistent performance.
