IXFH340N075T2 Equivalent & Substitute Parts

Part Overview

The IXFH340N075T2 is an N-Channel MOSFET manufactured by IXYS, rated for 75V drain-to-source voltage with 340A continuous drain current at 25°C. This device is part of the HiPerFET™ and TrenchT2™ series and is housed in a TO-247AD through-hole package. The component is Active in product status and RoHS3 compliant.

Substitute parts are identified when equivalent electrical performance can be achieved within the specified parameter ranges, accounting for differences in current rating, voltage rating, and power dissipation characteristics. Substitution becomes necessary when the primary part is unavailable or when application requirements permit operation within the electrical boundaries of alternative devices.

Substitute Part Grouping Explanation

Substitution of the IXFH340N075T2 is determined by the following critical electrical parameters:

Primary Substitution Criteria:

Drain-to-Source Voltage (Vdss): Must equal or exceed 75V
Continuous Drain Current (Id): Must support the application's current requirements
On-State Resistance (Rds On): Must be compatible with thermal and efficiency constraints
Gate Threshold Voltage (Vgs(th)): Must fall within ±20V maximum gate voltage specification
Operating Temperature Range: Must span -55°C to 175°C
Package Type: Through-hole TO-247 family variants acceptable
Compliance: RoHS3 compliant, REACH unaffected status required

The substitute parts listed below meet these criteria with the following considerations:

IRFP7537PBF: 60V rating (lower voltage rating than primary part); 172A continuous current; TO-247 package
IRFP3077PBF: 75V rating (matches primary part); 120A continuous current; TO-247AC package
IRFP3206PBF: 60V rating (lower voltage rating than primary part); 120A continuous current; TO-247AC package

All substitute parts are manufactured by Infineon Technologies, are Active in product status, and maintain RoHS3 compliance and REACH unaffected status.

Engineering Selection Recommendations

IRFP7537PBF Selection Criteria: This device is suitable for applications where the 60V Vdss rating is acceptable and current requirements do not exceed 172A. The lower power dissipation rating (230W) requires thermal management consideration. All regulatory compliance requirements are met.

IRFP3077PBF Selection Criteria: This device maintains the 75V Vdss rating of the primary part and is suitable for applications requiring continuous currents up to 120A. The power dissipation rating of 340W is lower than the primary part. All regulatory compliance requirements are met.

IRFP3206PBF Selection Criteria: This device operates at 60V Vdss and supports continuous currents up to 120A. The power dissipation rating of 280W is lower than the primary part. All regulatory compliance requirements are met.

All substitute parts maintain Active product status, RoHS3 compliance, and REACH unaffected designation. Selection between substitutes depends on application voltage and current requirements.

Frequently Asked Questions (FAQ)

Q: Can IRFP7537PBF replace IXFH340N075T2 in all applications?

A: No. The IRFP7537PBF has a lower Vdss rating (60V versus 75V) and lower continuous current rating (172A versus 340A). It is suitable only for applications where both the voltage and current requirements fall within its specifications.

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

A: Both are through-hole TO-247 family packages with three leads. The primary part uses TO-247AD, while substitute parts use TO-247 or TO-247AC variants. Pin configuration and mechanical dimensions may differ; physical verification is required for board-level compatibility.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are RoHS3 compliant and REACH unaffected, matching the compliance status of the primary part.

Q: Which substitute part has the lowest on-state resistance?

A: The IRFP3206PBF has the lowest Rds On specification at 3.0 mOhm @ 75A, 10V. However, this measurement is taken at a lower current level than the primary part's 3.2 mOhm @ 100A, 10V specification.

Q: Can I use IRFP3077PBF as a direct replacement for IXFH340N075T2?

A: The IRFP3077PBF maintains the 75V Vdss rating but has a significantly lower continuous current rating (120A versus 340A). It is suitable only for applications where current requirements do not exceed 120A. Package type differences (TO-247AC versus TO-247AD) require physical verification.

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

A: All parts, including the primary and substitute devices, operate across -55°C to 175°C junction temperature range.

Q: How do gate charge specifications compare?

A: The primary part has a gate charge of 300 nC @ 10V. Substitute parts range from 170 nC to 220 nC @ 10V, indicating faster switching characteristics in the substitute devices.
