ZDX080N50 Equivalent & Substitute Parts Reference

Part Overview

The ZDX080N50 from Rohm Semiconductor is an N-channel MOSFET in the Transistors, FETs, MOSFETs category. It is designed for high-voltage, medium current applications with a Drain-Source Voltage (Vdss) of 500 V and a continuous drain current (Id) of 8A (Tc), provided in a TO-220FM full pack through-hole package. The product status is "Not For New Designs," making it necessary to identify and consider substitute models with equivalent or superior performance characteristics for ongoing or new projects.

Engineering Selection Recommendations

Part selection must be based on product status and compliance certifications. The ZDX080N50 is not intended for new designs. The provided substitute, FDPF12N50T, is classified as obsolete. Both components are ROHS3 compliant and REACH unaffected, aligning with standard environmental certifications.

Frequently Asked Questions (FAQ)

Q1: What are the key electrical requirements for substituting MOSFETs in this category?
A1: The primary parameters include FET type, Drain-Source Voltage (Vdss), Continuous Drain Current (Id), Rds On, Gate Threshold Voltage (Vgs(th)), Maximum Gate Voltage (Vgs), Power Dissipation, Gate Charge, Input Capacitance, package type, and mounting method.

Q2: Are the mechanical dimensions and package types consistent between ZDX080N50 and FDPF12N50T?
A2: Both use a TO-220-3 Full Pack package and support through-hole mounting, ensuring mechanical compatibility.

Q3: Does RoHS and REACH compliance affect substitute part acceptance?
A3: Both ZDX080N50 and its substitute FDPF12N50T are ROHS3 compliant and REACH unaffected, meeting standard environmental and safety requirements for this product category.

Q4: Can parts with an “Obsolete” or “Not For New Designs” product status be used for ongoing or future projects?
A4: These parts are suitable for existing designs but are not intended for inclusion in new developments, due to restricted long-term availability.

Q5: Is there compatibility at the drive voltage level?
A5: Both ZDX080N50 and FDPF12N50T require a 10V drive voltage for optimal Rds On performance.
