IXTY01N80 N-Channel MOSFET 800V 100mA Equivalent & Substitute Parts

Part Overview

The IXTY01N80 is an N-Channel MOSFET manufactured by IXYS, rated for 800V drain-to-source voltage with 100mA continuous drain current at 25°C. The device is housed in a Surface Mount TO-252AA package and is designed for high-voltage switching applications requiring 25W maximum power dissipation.

The IXTY01N80 is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IXTY01N80 is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Drain-to-Source Voltage (Vdss) rating must equal or exceed 800V
• Continuous Drain Current (Id) must support the application's current requirements
• On-State Resistance (Rds On) must be compatible with switching losses and thermal management
• Gate Threshold Voltage (Vgs(th)) must fall within acceptable control voltage ranges
• Gate Charge (Qg) and Input Capacitance (Ciss) must be compatible with gate drive circuitry
• Maximum Gate Voltage (Vgs Max) must accommodate the gate drive voltage
• Power Dissipation rating must support thermal requirements
• Operating Temperature range must cover the application environment

Mechanical Compatibility Criteria:

• Package type must be TO-252AA (DPAK, 2 Leads + Tab, SC-63)
• Surface Mount mounting type required
• Pin configuration must be identical

Regulatory & Compliance Criteria:

• RoHS3 Compliance required
• MSL rating of 1 (Unlimited) required
• REACH Unaffected status required

The substitute part RFD3055LESM9A does not meet the electrical compatibility requirements for direct substitution due to significantly lower Vdss rating (60V versus 800V). This part operates in a different voltage class and is not suitable for applications requiring 800V operation.

Parameter Comparison

Engineering Selection Recommendations

The RFD3055LESM9A is not suitable as a direct substitute for the IXTY01N80 in applications requiring 800V operation. The substitute part is rated for only 60V maximum drain-to-source voltage, representing a 13.3:1 reduction in voltage rating. This fundamental electrical incompatibility makes the RFD3055LESM9A unsuitable for high-voltage switching applications designed around the IXTY01N80.

Both parts share identical mechanical compatibility: Surface Mount TO-252AA (DPAK) package with identical pin configuration. Both parts meet RoHS3 compliance, MSL 1 (Unlimited) rating, and REACH Unaffected status.

For applications requiring an 800V N-Channel MOSFET in TO-252AA packaging, alternative parts must be evaluated based on voltage rating equivalence rather than the RFD3055LESM9A, which operates in a different voltage class.

Frequently Asked Questions (FAQ)

Q: Can the RFD3055LESM9A replace the IXTY01N80 in my circuit?

A: No. The RFD3055LESM9A is rated for 60V maximum drain-to-source voltage, while the IXTY01N80 is rated for 800V. Using a 60V device in an 800V application will result in device failure. The parts operate in different voltage classes and are not interchangeable.

Q: Are the packages physically identical?

A: Yes. Both the IXTY01N80 and RFD3055LESM9A use the TO-252AA (DPAK) Surface Mount package with identical pin configuration. Physical board-level compatibility exists, but electrical incompatibility prevents substitution.

Q: What is the primary reason these parts cannot be substituted?

A: The drain-to-source voltage rating (Vdss) is the limiting factor. The IXTY01N80 is designed for 800V applications, while the RFD3055LESM9A is designed for 60V applications. This 13.3:1 difference in voltage rating makes them unsuitable for cross-application use.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are RoHS3 Compliant, carry MSL 1 (Unlimited) rating, and have REACH Unaffected status. Regulatory and environmental compliance is equivalent between the two parts.

Q: What should I do if I need to replace an obsolete IXTY01N80?

A: Identify alternative N-Channel MOSFETs with 800V or higher Vdss rating in TO-252AA packaging. The RFD3055LESM9A does not meet the voltage requirement. Consult component datasheets to verify that all electrical parameters, including Vdss, Rds On, gate charge, and input capacitance, are compatible with your circuit design.

Q: Why is the RFD3055LESM9A listed as a substitute if it cannot be used?

A: The RFD3055LESM9A shares the same package type and mounting technology as the IXTY01N80, but electrical parameters differ significantly. It is listed to clarify that while mechanical compatibility exists, electrical incompatibility prevents substitution. Direct voltage class equivalents must be identified separately.
