STP80NF55 MOSFET N-CH 55V 80A TO220 Equivalent & Substitute Parts

Part Overview

The STP80NF55 is an N-channel MOSFET manufactured by STMicroelectronics, rated for 55V drain-to-source voltage and 80A continuous drain current in a Through Hole TO-220 package. This device is classified as Obsolete product status. Due to obsolescence, equivalent substitute parts from active product lines are necessary to maintain design continuity and ensure long-term component availability for new production and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the STP80NF55 are selected based on the following critical parameters that determine functional compatibility:

Primary Substitution Criteria:

• FET Type: N-Channel (all substitutes must be N-Channel)
• Mounting Type: Through Hole (all substitutes must be Through Hole)
• Package / Case: TO-220-3 (all substitutes must use TO-220-3 package)
• Drain to Source Voltage (Vdss): 55V or higher (substitutes rated at 55V or 60V are acceptable)
• Current - Continuous Drain (Id) @ 25°C: 75A or higher (substitutes rated at 75A or 120A meet or exceed the original 80A specification)
• RoHS Status: ROHS3 Compliant (all substitutes must maintain compliance)
• Moisture Sensitivity Level (MSL): 1 (Unlimited) (all substitutes must match or exceed this rating)

The three substitute parts listed (IRF1010EZPBF, IRF3205ZPBF, IRFB3206PBF) are all manufactured by Infineon Technologies and carry Active product status, ensuring long-term availability and supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are manufactured by Infineon Technologies and carry Active product status, ensuring availability and ongoing manufacturer support. Each substitute maintains ROHS3 compliance and MSL 1 (Unlimited) rating, matching the original STP80NF55 environmental and regulatory requirements.

IRF1010EZPBF is suitable for applications where the 55V voltage rating of the original part is critical and current requirements do not exceed 75A. This part provides a direct voltage-class match at 60V with slightly reduced current capacity.

IRF3205ZPBF provides an exact voltage-class match at 55V with 75A continuous drain current. This part is appropriate for designs where the original 55V specification is a primary design constraint.

IRFB3206PBF offers enhanced current handling at 120A continuous drain current with a 60V voltage rating. This part is suitable for applications requiring higher current capacity than the original 80A specification or where voltage headroom above 55V is acceptable.

All substitute parts use the TO-220-3 package and Through Hole mounting type, ensuring mechanical and electrical compatibility with existing PCB layouts and thermal management solutions designed for the STP80NF55.

Frequently Asked Questions (FAQ)

Q: Can the IRF1010EZPBF replace the STP80NF55 in all applications?

A: The IRF1010EZPBF is compatible with STP80NF55 applications from a package and mounting perspective. However, the IRF1010EZPBF is rated at 60V (versus 55V) and 75A (versus 80A). Applications operating at or near the 80A specification may require evaluation of the reduced current rating.

Q: What is the difference between IRF3205ZPBF and IRF1010EZPBF?

A: Both parts are rated at 75A continuous drain current. The IRF3205ZPBF matches the original 55V voltage rating exactly, while the IRF1010EZPBF is rated at 60V. The IRF3205ZPBF is the preferred substitute when the 55V specification is a design requirement.

Q: Is the IRFB3206PBF suitable for designs that do not require 120A current capacity?

A: Yes. The IRFB3206PBF is rated at 120A continuous drain current, which exceeds the original 80A specification. It can be used in applications requiring 80A or less. The higher current rating does not create compatibility issues in lower-current applications.

Q: Are all substitute parts available in the same packaging format?

A: All substitute parts use the TO-220-3 package in Through Hole mounting configuration, matching the original STP80NF55 package specification. Packaging format is identical across all substitutes.

Q: Do the substitute parts meet the same compliance standards as the STP80NF55?

A: Yes. All substitute parts are ROHS3 compliant and carry MSL 1 (Unlimited) rating, matching the original part's environmental and regulatory compliance status.

Q: Why is the STP80NF55 listed as Obsolete?

A: The STP80NF55 is classified as Obsolete by STMicroelectronics. The substitute parts listed are from Infineon Technologies and carry Active product status, ensuring continued availability and manufacturer support for new designs and production requirements.
