IXTY2N80P Equivalent & Substitute Parts

Part Overview

The IXTY2N80P is an N-Channel MOSFET manufactured by IXYS, rated for 800V drain-to-source voltage with 2A continuous drain current at 25°C. This device is part of the PolarHV™ series and is housed in a TO-252AA surface mount package. The part is currently classified as obsolete, making identification of equivalent and substitute components essential for design continuity and procurement planning.

Substitute parts are necessary due to the obsolete status of the IXTY2N80P. Active alternatives with comparable electrical and mechanical specifications enable system designers to maintain performance requirements while ensuring long-term component availability.

Substitute Part Grouping Explanation

Substitution of the IXTY2N80P is determined by the following critical parameters:

Voltage Rating Compatibility: The drain-to-source voltage (Vdss) must equal or exceed 800V to maintain circuit protection margins in high-voltage applications.

Current Rating Compatibility: The continuous drain current (Id) must equal or exceed 2A at 25°C to support the same load conditions.

On-Resistance (Rds On): The maximum on-resistance at rated conditions should not significantly exceed 6 Ohm to maintain thermal performance and power dissipation characteristics.

Package Compatibility: All substitute parts must use the TO-252-3 DPAK surface mount package to ensure mechanical and thermal compatibility with existing PCB layouts.

Operating Temperature Range: The operating temperature range must span -55°C to 150°C to match the thermal envelope of the original design.

Substitute parts are grouped into two categories:

Category 1 – Direct Voltage/Current Match (800V, 2A): Parts meeting or exceeding both the 800V voltage rating and 2A current rating with comparable on-resistance and thermal characteristics.

Category 2 – Lower Voltage Alternatives (600V): Parts with reduced voltage ratings suitable only for applications where the 800V rating is not a functional requirement.

Engineering Selection Recommendations

Primary Substitute – STD2N80K5 (STMicroelectronics)

The STD2N80K5 is the recommended primary substitute for the IXTY2N80P. This part maintains the critical 800V voltage rating and 2A current rating, ensuring full compatibility with high-voltage circuit designs. The STD2N80K5 features improved on-resistance (4.5 Ohm versus 6 Ohm) and significantly lower gate charge (3 nC versus 10.6 nC), resulting in enhanced switching efficiency and reduced thermal stress. The device is active in production, ROHS3 compliant, and available in high inventory quantities (688,300 units). The TO-252-3 DPAK package provides direct mechanical compatibility with existing PCB layouts.

Secondary Substitute – IXFY4N85X (IXYS)

The IXFY4N85X serves as a secondary substitute with enhanced performance characteristics. This part exceeds the voltage rating (850V) and current rating (3.5A), providing additional design margin for high-voltage applications. The IXFY4N85X delivers superior on-resistance (2.5 Ohm) and lower gate charge (7 nC), supporting higher efficiency designs. The device is active in production and ROHS3 compliant. The TO-252AA package maintains mechanical compatibility. This substitute is suitable for applications requiring performance enhancement beyond the original specification.

Lower Voltage Alternatives – IRFR1N60APBF, IRFR1N60ATRLPBF, RJK6002DPD-00#J2

These three parts operate at 600V, representing a 200V reduction from the original 800V rating. These alternatives are suitable only for applications where the 800V voltage rating is not a functional requirement. All three devices are active in production and ROHS3 compliant. The IRFR1N60APBF and IRFR1N60ATRLPBF are functionally identical Vishay Siliconix parts, differentiated only by packaging format (Tube versus Cut Tape). The RJK6002DPD-00#J2 from Renesas Electronics maintains the 2A current rating and comparable on-resistance (6.8 Ohm), making it suitable for direct substitution in 600V applications.

Frequently Asked Questions (FAQ)

Q: Can the STD2N80K5 directly replace the IXTY2N80P in all applications?

A: Yes, the STD2N80K5 provides direct substitution for the IXTY2N80P. Both devices share the same 800V voltage rating, 2A current rating, and TO-252-3 DPAK package. The STD2N80K5 features improved electrical characteristics (lower on-resistance and gate charge), which enhance system performance without requiring circuit modifications.

Q: What is the key difference between the IXFY4N85X and the IXTY2N80P?

A: The IXFY4N85X exceeds the original specification with a higher voltage rating (850V versus 800V) and higher current rating (3.5A versus 2A). The on-resistance is significantly lower (2.5 Ohm versus 6 Ohm), and gate charge is reduced (7 nC versus 10.6 nC). These improvements result in lower power dissipation and faster switching characteristics. The IXFY4N85X is suitable for applications requiring enhanced performance or additional design margin.

Q: Why are the 600V alternatives (IRFR1N60APBF, IRFR1N60ATRLPBF, RJK6002DPD-00#J2) listed as substitutes if they have a lower voltage rating?

A: These 600V parts are listed as alternatives for applications where the 800V voltage rating is not a functional requirement. They are not direct substitutes for high-voltage designs but serve as options for lower-voltage circuit implementations. Selection of these parts requires verification that the application circuit operates safely at 600V maximum voltage.

Q: What is the difference between IRFR1N60APBF and IRFR1N60ATRLPBF?

A: These two Vishay Siliconix parts are electrically identical. The difference is in packaging format: IRFR1N60APBF is supplied in Tube packaging, while IRFR1N60ATRLPBF is supplied in Cut Tape (CT) format. Both parts have identical electrical specifications, operating temperature range, and RoHS compliance status. Selection between these two depends on procurement and assembly requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all active substitute parts listed (STD2N80K5, IXFY4N85X, IRFR1N60APBF, IRFR1N60ATRLPBF, and RJK6002DPD-00#J2) are ROHS3 compliant. The original IXTY2N80P does not specify RoHS status due to its obsolete classification.

Q: Can the RJK6002DPD-00#J2 be used as a direct replacement for the IXTY2N80P?

A: The RJK6002DPD-00#J2 cannot be used as a direct replacement due to its 600V voltage rating, which is 200V lower than the IXTY2N80P. However, it maintains the 2A current rating and comparable on-resistance (6.8 Ohm). This part is suitable only for applications where the circuit operates at 600V or lower maximum voltage.

Q: What is the significance of the lower gate charge in the STD2N80K5 compared to the IXTY2N80P?

A: The STD2N80K5 has a gate charge of 3 nC compared to 10.6 nC in the IXTY2N80P. Lower gate charge results in faster switching transitions, reduced gate drive power requirements, and lower switching losses. This characteristic improves overall system efficiency and thermal performance, particularly in high-frequency switching applications.

Q: Are the TO-252AA and DPAK packages mechanically compatible?

A: The TO-252AA and DPAK packages are mechanically and thermally compatible. Both designations refer to the same physical package format: TO-252-3 with 2 leads plus a thermal tab. Parts specified as TO-252AA or DPAK can be used interchangeably in PCB layouts designed for this package type.

Q: What inventory status should be considered when selecting a substitute?

A: The STD2N80K5 has the highest inventory availability (688,300 units), ensuring long-term procurement security. The IXFY4N85X (761 units) and other alternatives have lower inventory levels. For critical applications requiring sustained component availability, the STD2N80K5 is the preferred choice.
