FR85JR05 Equivalent & Substitute Parts Engineering Reference

Part Overview

The GeneSiC Semiconductor FR85JR05 is a diode designed for general-purpose, reverse polarity applications in the diodes and rectifiers category. It features a maximum reverse voltage of 600 V, average rectified current of 85A, fast recovery time of 500 ns, and a DO-203AB, DO-5, stud mount package. This part is active and RoHS compliant. Alternative models are sought for supply chain flexibility, to ensure consistent production flow, and to support design-in requirements in case of allocation, lead time, or inventory variations.

Key Parameters

Substitute Part Grouping Explanation

Parametric equivalent and substitute parts are grouped based on identical or tighter tolerance in allowed parameters: Voltage - DC Reverse (Vr) (Max), Current - Average Rectified (Io), Voltage - Forward (Vf) (Max) @ If, Speed classification (Fast Recovery <= 500ns, > 200mA Io), Reverse Recovery Time (trr), Reverse Leakage Current, package (DO-203AB, DO-5, Stud), mounting type, operating temperature range, RoHS status, and Moisture Sensitivity Level. Only parts matching these parameters without exceeding maximum ratings are included as valid substitutes.

Parameter Comparison

Engineering Selection Recommendations

All listed equivalent and substitute part numbers, including FR85JR02, are RoHS compliant and have Moisture Sensitivity Level 1 (Unlimited). Both parts are in active status. Only use parts with matching compliance and active product status as direct substitutes in assemblies or BOMs where RoHS requirements apply.

Frequently Asked Questions (FAQ)

Q1: What criteria are used for selecting equivalent or substitute diodes in the DO-203AB, DO-5, Stud category?
A1: Substitution is based strictly on matching Voltage - DC Reverse (Vr) (Max), Current - Average Rectified (Io), Voltage - Forward (Vf) (Max) @ If, speed, reverse recovery time (trr), reverse leakage, mechanical package, mounting type, and compliance.

Q2: Are FR85JR05 and FR85JR02 interchangeable in all applications using DO-5 package?
A2: Both parts share the same maximum voltage, current, forward voltage, package, mounting, operating temperature range, RoHS status, and MSL, differing only in reverse recovery time (trr).

Q3: Can these substitutes be used directly on a BOM without additional qualification?
A3: If product status is active and compliance matches, these substitutions are valid per the provided parameters.

Q4: Is mechanical compatibility ensured between FR85JR05 and FR85JR02?
A4: Both use an identical package and mounting type (DO-203AB, DO-5, Stud, Chassis mount), ensuring form and fit compatibility within the constraints specified.

Q5: What is the Reverse Recovery Time (trr) difference between the parts?
A5: FR85JR05 has a trr of 500 ns; FR85JR02 has a trr of 250 ns. Both are classified as Fast Recovery <= 500ns, > 200mA (Io).

Q6: Which environmental ratings are covered?
A6: Both listed parts are RoHS compliant with Moisture Sensitivity Level 1 (Unlimited), supporting lead-free and standard storage/handling practices.
