IXFX32N100P N-Channel MOSFET Equivalent & Substitute Parts

Part Overview

The IXFX32N100P is an N-Channel MOSFET manufactured by IXYS, rated for 1000V drain-to-source voltage with 32A continuous drain current at 25°C. This device is part of the HiPerFET™ Polar series and is housed in a PLUS247™-3 package (TO-247-3 variant). The part is currently in active production status with 2100 units in stock.

Equivalent and substitute parts are identified when alternative devices meet the same functional requirements within specified electrical and mechanical tolerances. Substitutes are necessary when the primary part becomes unavailable, when inventory constraints require alternative sourcing, or when design flexibility permits selection from multiple qualified suppliers.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IXFX32N100P is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Drain-to-Source Voltage (Vdss) must equal or exceed 1000V
• Continuous Drain Current (Id) must equal or exceed 32A at 25°C
• On-State Resistance (Rds On) must not exceed 320 mOhm at specified gate voltage
• Gate Threshold Voltage (Vgs(th)) must be compatible with 10V drive voltage
• Operating temperature range must encompass -55°C to 150°C

Mechanical Compatibility Criteria:

• Package type must be TO-247-3 (Through Hole)
• FET type must be N-Channel
• Technology must be MOSFET (Metal Oxide)

The STW22N95K5 from STMicroelectronics is listed as a substitute part. However, this device exhibits the following parameter deviations from the IXFX32N100P:

• Vdss: 950V (50V lower than required 1000V specification)
• Id: 17.5A (14.5A lower than required 32A specification)
• Power Dissipation: 250W (710W lower than required 960W specification)

These deviations indicate the STW22N95K5 operates within a reduced electrical envelope and is not a direct functional equivalent for applications requiring the full 1000V/32A rating of the IXFX32N100P.

Parameter Comparison

Engineering Selection Recommendations

IXFX32N100P Selection: The IXFX32N100P remains the appropriate choice for applications requiring the full specified electrical performance envelope of 1000V/32A/960W. This device is in active production status with adequate inventory availability (2100 units in stock). The part maintains ROHS3 compliance, MSL Level 1 rating, and REACH unaffected status, meeting standard environmental and regulatory requirements.

STW22N95K5 Consideration: The STW22N95K5 is in active production status and carries AEC-Q101 automotive qualification. However, this device operates at reduced voltage (950V), reduced current (17.5A), and reduced power dissipation (250W) compared to the IXFX32N100P. The STW22N95K5 is suitable only for applications where the lower electrical ratings are acceptable and where the automotive qualification is required. Both devices share identical operating temperature range (-55°C to 150°C), identical package type (TO-247-3), and identical regulatory compliance status (ROHS3, REACH unaffected, MSL 1).

Direct substitution of the STW22N95K5 for the IXFX32N100P is not recommended for applications designed to the full 1000V/32A specification.

Frequently Asked Questions (FAQ)

Q: Can the STW22N95K5 be used as a direct replacement for the IXFX32N100P?

A: No. The STW22N95K5 has lower electrical ratings (950V vs. 1000V, 17.5A vs. 32A, 250W vs. 960W). Direct substitution is only valid if the application circuit operates within the reduced electrical envelope of the STW22N95K5.

Q: Are both devices housed in the same package?

A: Yes. Both the IXFX32N100P and STW22N95K5 use the TO-247-3 through-hole package, ensuring mechanical compatibility in PCB layouts designed for this form factor.

Q: What are the key electrical differences between these devices?

A: The primary differences are drain-to-source voltage (1000V vs. 950V), continuous drain current (32A vs. 17.5A), and maximum power dissipation (960W vs. 250W). Gate charge is significantly lower in the STW22N95K5 (48 nC vs. 225 nC), which affects switching speed characteristics.

Q: Do both devices meet the same regulatory standards?

A: Both devices are ROHS3 compliant, have MSL Level 1 rating, and REACH unaffected status. The STW22N95K5 carries additional AEC-Q101 automotive qualification, which the IXFX32N100P does not list.

Q: What is the operating temperature range for both devices?

A: Both devices operate across the identical temperature range of -55°C to 150°C (TJ), ensuring thermal compatibility in equivalent thermal environments.

Q: Which device should be selected for new designs?

A: Selection depends on application requirements. For designs requiring 1000V/32A performance, the IXFX32N100P is the appropriate choice. For automotive applications with lower voltage/current requirements, the STW22N95K5 with AEC-Q101 qualification may be suitable.
