IXTH88N30P N-Channel 300V 88A MOSFET Equivalent & Substitute Parts

Part Overview

The IXTH88N30P is an N-Channel MOSFET manufactured by IXYS, rated for 300V drain-to-source voltage and 88A continuous drain current at 25°C. This device is housed in a TO-247 through-hole package and is designed for high-power switching applications requiring robust thermal performance up to 600W. The part is currently in active production status with RoHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are identified when equivalent electrical performance can be achieved within the specified parameter ranges, accounting for differences in voltage ratings, current capacity, and thermal characteristics. Alternative devices may be necessary due to inventory availability, lead time considerations, or application-specific thermal and electrical requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IXTH88N30P is determined by the following critical parameters:

Voltage Rating Compatibility: The substitute device must support the application's maximum drain-to-source voltage requirement. The IXTH88N30P operates at 300V; substitute parts with equal or higher Vdss ratings are acceptable.

Current Capacity: The continuous drain current rating must meet or exceed the application's steady-state current demand. The IXTH88N30P provides 88A; substitute parts with equal or higher Id ratings are suitable.

On-State Resistance (Rds On): This parameter directly affects power dissipation and thermal performance. Lower Rds On values reduce conduction losses and improve efficiency.

Gate Charge (Qg): This parameter influences switching speed and gate drive requirements. Lower gate charge enables faster switching transitions.

Thermal Performance: Power dissipation capability must support the application's thermal budget. The IXTH88N30P dissipates up to 600W.

Package and Mounting: The TO-247 through-hole package establishes mechanical and thermal interface requirements.

Compliance and Status: Active product status and RoHS3 compliance ensure long-term availability and regulatory conformance.

Parameter Comparison

Engineering Selection Recommendations

IXTH88N30P as Primary Selection: The IXTH88N30P is the specified component for applications requiring 300V operation with 88A continuous current capacity and 600W thermal dissipation. This device is in active production with full RoHS3 compliance and unlimited moisture sensitivity rating, ensuring long-term supply chain stability.

IRFP4229PBF as Substitute: The IRFP4229PBF from Infineon Technologies is an alternative N-Channel MOSFET suitable for applications where the voltage and current requirements are lower than the primary specification. This device operates at 250V maximum drain-to-source voltage with 44A continuous current capacity and 310W power dissipation. The IRFP4229PBF is also in active production with RoHS3 compliance.

Substitution Constraints: The IRFP4229PBF has reduced voltage rating (250V versus 300V), reduced current capacity (44A versus 88A), and reduced power dissipation capability (310W versus 600W). These differences limit its use to applications with lower electrical and thermal demands. The IRFP4229PBF exhibits lower gate charge (110nC versus 180nC) and lower input capacitance (4560pF versus 6300pF), resulting in faster switching characteristics.

Compliance Basis: Both devices maintain active product status and RoHS3 compliance, supporting regulatory requirements and supply chain continuity. Selection between these parts must be based on the specific application's voltage, current, and thermal requirements.

Frequently Asked Questions (FAQ)

Q: Can the IRFP4229PBF directly replace the IXTH88N30P in all applications?

A: No. The IRFP4229PBF has lower electrical ratings across three critical parameters: drain-to-source voltage (250V versus 300V), continuous drain current (44A versus 88A), and power dissipation (310W versus 600W). Substitution is valid only for applications where these reduced ratings are sufficient for the intended circuit operation.

Q: What is the significance of the voltage rating difference between these devices?

A: The IXTH88N30P is rated for 300V drain-to-source operation, while the IRFP4229PBF is rated for 250V. Applications operating at voltages above 250V require the IXTH88N30P to maintain adequate safety margin and prevent device failure. The 50V difference represents a 20% reduction in voltage capability.

Q: How do the current ratings affect substitution decisions?

A: The IXTH88N30P provides 88A continuous drain current, while the IRFP4229PBF provides 44A. Applications requiring current levels between 44A and 88A cannot use the IRFP4229PBF without exceeding its maximum continuous current rating. The IXTH88N30P must be used for higher-current applications.

Q: What is the impact of power dissipation differences?

A: The IXTH88N30P dissipates up to 600W, while the IRFP4229PBF dissipates up to 310W. Applications with thermal budgets exceeding 310W require the IXTH88N30P. The lower power dissipation rating of the IRFP4229PBF indicates reduced thermal capacity and may require enhanced cooling solutions or lower operating currents.

Q: Are the package types compatible?

A: Both devices use TO-247 through-hole packages. The IXTH88N30P uses TO-247 (IXTH) and the IRFP4229PBF uses TO-247AC. These packages are mechanically compatible with standard TO-247 footprints and mounting hardware, though minor pin configuration differences may exist. Verify pin assignments before installation.

Q: Do both devices meet the same compliance standards?

A: Yes. Both the IXTH88N30P and IRFP4229PBF are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Both devices carry unlimited moisture sensitivity rating (MSL 1). Compliance requirements do not differentiate between these parts.

Q: What are the gate charge implications for circuit design?

A: The IXTH88N30P has gate charge of 180nC at 10V, while the IRFP4229PBF has 110nC. Lower gate charge in the IRFP4229PBF enables faster switching transitions and reduces gate drive power requirements. Applications with stringent switching speed requirements may benefit from the IRFP4229PBF's lower gate charge, provided voltage and current ratings are adequate.

Q: How do operating temperature ranges compare?

A: The IXTH88N30P operates from -55°C to 150°C junction temperature, while the IRFP4229PBF operates from -40°C to 175°C. The IRFP4229PBF has a wider upper temperature limit (175°C versus 150°C) but a narrower lower temperature limit (-40°C versus -55°C). Applications requiring operation below -40°C require the IXTH88N30P.
