IXTA2N80 N-Channel MOSFET 800V 2A Equivalent & Substitute Parts

Part Overview

The IXTA2N80 is an N-Channel MOSFET rated for 800V drain-to-source voltage with a continuous drain current of 2A at 25°C. This device is packaged in a Surface Mount TO-263AA (D2PAK) configuration and is designed for high-voltage switching applications. The IXTA2N80 is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support, production continuity, and system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IXTA2N80 is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

• Drain to Source Voltage (Vdss): Must equal or exceed 800V
• FET Type: Must be N-Channel
• Technology: Must be MOSFET (Metal Oxide)
• Mounting Type: Must be Surface Mount
• Package / Case: Must be compatible with TO-263-3, D2PAK configuration

Functional Compatibility Parameters:

• Continuous Drain Current (Id) @ 25°C: Substitute must support minimum 2A
• Operating Temperature Range: Must encompass -55°C to 150°C
• Gate Voltage Rating (Vgs): Must support ±20V or greater

Compliance Parameters:

• RoHS Status: Must be ROHS3 Compliant
• Moisture Sensitivity Level: Must be MSL 1 or equivalent
• REACH Status: Must be REACH Unaffected

The IXFA7N80P qualifies as a direct substitute based on these criteria. While it provides enhanced electrical performance characteristics (higher current rating, lower on-resistance, and greater power dissipation capability), it maintains full compatibility with the IXTA2N80 in terms of voltage rating, package type, temperature range, and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The IXFA7N80P is the manufacturer-recommended substitute for the obsolete IXTA2N80. Both devices are manufactured by IXYS and share identical voltage ratings, package configurations, and operating temperature ranges. Both are ROHS3 Compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings.

The IXFA7N80P is classified as an Active product, ensuring ongoing availability and supply chain continuity. The IXTA2N80, designated as Obsolete, presents supply constraints and long-term sourcing risks.

From an electrical standpoint, the IXFA7N80P provides superior performance characteristics within the same physical package. The higher continuous drain current rating (7A versus 2A), reduced on-resistance (1.44Ohm versus 6.2Ohm), and increased power dissipation capability (200W versus 54W) make the IXFA7N80P suitable for applications requiring the IXTA2N80 specifications while offering design margin and performance headroom.

Both devices maintain the same 800V drain-to-source voltage rating and operate across the identical temperature range (-55°C to 150°C). The TO-263AA package compatibility ensures direct mechanical and thermal interface equivalence.

Frequently Asked Questions (FAQ)

Q: Can the IXFA7N80P directly replace the IXTA2N80 in existing designs?

A: Yes. Both devices share identical voltage ratings (800V Vdss), package type (TO-263-3, D2PAK), operating temperature range (-55°C to 150°C), and regulatory compliance status (ROHS3 Compliant, REACH Unaffected). The IXFA7N80P is pin-compatible and mechanically interchangeable with the IXTA2N80.

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

A: The IXFA7N80P provides higher current handling capability (7A continuous versus 2A), lower on-resistance (1.44Ohm versus 6.2Ohm at rated conditions), and greater power dissipation capacity (200W versus 54W). These differences represent performance enhancements within the same voltage class and package footprint.

Q: Why is the IXTA2N80 listed as Obsolete?

A: The IXTA2N80 has been discontinued by the manufacturer. The IXFA7N80P represents the active, supported alternative from IXYS for new designs and production continuity.

Q: Are there any gate drive considerations when substituting the IXFA7N80P for the IXTA2N80?

A: Both devices operate with a 10V drive voltage for maximum on-resistance specification. The IXFA7N80P supports a higher maximum gate voltage (±30V versus ±20V), providing additional design flexibility. Gate charge differs (32nC versus 22nC at 10V), which may affect switching speed characteristics in gate drive circuits.

Q: Is the TO-263AA package identical for both devices?

A: Yes. Both the IXTA2N80 and IXFA7N80P use the TO-263-3 D2PAK (2 Leads + Tab) package configuration, ensuring identical PCB footprint, thermal interface, and mounting requirements.

Q: What is the moisture sensitivity level for both devices?

A: Both devices carry MSL 1 (Unlimited) moisture sensitivity rating, indicating no moisture-related handling restrictions during storage, transport, or assembly.

Q: Are both devices RoHS compliant?

A: Yes. Both the IXTA2N80 and IXFA7N80P are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.
