Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the IXTP98N075T are selected based on the following critical parameters that must align with the original device:

Mandatory Matching Parameters:

• FET Type: N-Channel
• Technology: MOSFET (Metal Oxide)
• Drain to Source Voltage (Vdss): 75V
• Package / Case: TO-220-3
• Mounting Type: Through Hole
• Operating Temperature Range: -55°C to 175°C (TJ)
• RoHS Status: ROHS3 Compliant

Current Rating Consideration: The IXTP98N075T specifies 98A continuous drain current at case temperature (Tc). Substitute parts must maintain equivalent or superior current handling capability to ensure functional compatibility in the target application.

Gate Threshold Voltage (Vgs(th)): All substitute parts maintain a maximum gate threshold voltage of 4V at the specified test current, ensuring consistent gate drive requirements.

Maximum Gate Voltage (Vgs): Substitute parts operate within ±20V to ±25V maximum gate voltage specifications, all compatible with standard gate drive circuits.

The three substitute parts listed below satisfy all mandatory parameters and provide active product status with full compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

AOT470 (Alpha & Omega Semiconductor Inc.)

The AOT470 is an active product with ROHS3 compliance and MSL 1 rating. It provides 100A continuous drain current at case temperature, exceeding the IXTP98N075T specification of 98A. Maximum power dissipation reaches 268W at case temperature. The device supports ±25V maximum gate voltage, offering broader gate drive compatibility than the original part. This substitute is suitable for applications requiring equivalent or higher current capacity within the 75V voltage class.

STP75NF75 (STMicroelectronics)

The STP75NF75 is an active STripFET™ II series device with ROHS3 compliance and MSL 1 rating. It delivers 80A continuous drain current at case temperature with 300W maximum power dissipation. The part maintains ±20V maximum gate voltage specification matching the original device. This substitute is appropriate for applications where the 80A current rating is sufficient and where the higher power dissipation capability provides thermal margin.

STP76NF75 (STMicroelectronics)

The STP76NF75 is an active STripFET™ II series device with ROHS3 compliance and MSL 1 rating. Electrical specifications are identical to the STP75NF75, providing 80A continuous drain current and 300W maximum power dissipation. Both STMicroelectronics parts share the same performance characteristics and series designation. This substitute is appropriate for applications where the 80A current rating is sufficient and where the higher power dissipation capability provides thermal margin.

Product Status Consideration:

All three substitute parts carry active product status, ensuring long-term availability and manufacturing support. The IXTP98N075T obsolete status necessitates transition to one of these active alternatives for new designs and ongoing production requirements.

Frequently Asked Questions (FAQ)

Q: Can the AOT470 directly replace the IXTP98N075T in all applications?

A: The AOT470 matches all mandatory electrical and mechanical parameters: 75V Vdss, N-Channel MOSFET technology, TO-220-3 package, Through Hole mounting, and -55°C to 175°C operating range. The 100A continuous drain current exceeds the original 98A specification. Compliance certifications (ROHS3, MSL 1) are identical. Direct substitution is supported for applications within these electrical specifications.

Q: What is the difference between STP75NF75 and STP76NF75?

A: Both parts are STMicroelectronics STripFET™ II series devices with identical electrical specifications: 75V Vdss, 80A continuous drain current, 300W maximum power dissipation, and ±20V maximum gate voltage. Both are active products with ROHS3 compliance and MSL 1 rating. The parts are functionally equivalent for substitution purposes.

Q: Why does the IXTP98N075T have a lower current rating (98A) than the AOT470 (100A)?

A: Current ratings reflect manufacturer test conditions and thermal design specifications. The AOT470 achieves 100A at case temperature (Tc) while the IXTP98N075T achieves 98A at case temperature. Both devices operate within the same 75V voltage class and TO-220-3 package. The AOT470 provides equivalent or superior current handling capability.

Q: Are all substitute parts RoHS compliant?

A: All substitute parts listed (AOT470, STP75NF75, STP76NF75) carry ROHS3 Compliant status, matching the original IXTP98N075T certification. All parts also maintain MSL 1 (Unlimited) moisture sensitivity level.

Q: Can I use a substitute part with lower current rating (80A) in place of the IXTP98N075T (98A)?

A: The STP75NF75 and STP76NF75 both specify 80A continuous drain current at case temperature, which is lower than the original 98A specification. Substitution with these parts is valid only when the application circuit design operates at or below 80A continuous drain current. Thermal design and current distribution must be verified for the specific application.

Q: What is the significance of the TO-220-3 package specification?

A: The TO-220-3 package is a Through Hole configuration with three leads (Gate, Drain, Source). All substitute parts maintain this identical package specification, ensuring mechanical and electrical compatibility with existing PCB layouts and thermal management solutions.

Q: Do all substitute parts support the same gate drive voltage?

A: The IXTP98N075T, STP75NF75, and STP76NF75 all specify ±20V maximum gate voltage. The AOT470 supports ±25V maximum gate voltage, providing broader compatibility with gate drive circuits. All parts maintain 4V maximum gate threshold voltage, ensuring consistent gate drive requirements.

Q: What is the operating temperature range for all parts?

A: All parts, including the original IXTP98N075T and all three substitutes (AOT470, STP75NF75, STP76NF75), operate across -55°C to 175°C junction temperature (TJ) range, ensuring thermal compatibility across the full specified operating envelope.
