FML-13S Diode Array Equivalent & Substitute Parts Reference

Part Overview

The FML-13S from Sanken Electric USA Inc. is a diode array featuring a 1 pair common cathode configuration with a maximum reverse voltage of 300 V and a forward current rating of 5 A per diode. Housed in a TO-220-3 Full Pack package for through hole mounting, the FML-13S utilizes standard technology and provides fast recovery characteristics. This product is currently classified as obsolete, making alternative model selection necessary for ongoing production, maintenance, or design continuity.

Substitute Part Grouping Explanation

Substitution is determined by matching the electrical and mechanical key parameters. These parameters are: diode configuration, reverse voltage rating, average rectified current, forward voltage characteristic, reverse recovery time, reverse leakage current, package type, mounting method, and RoHS status. Only parts that are strictly equivalent in these specified parameters are considered direct substitutes for the FML-13S in the Diodes, Rectifiers component category.

Engineering Selection Recommendations

FML-13S is identified as obsolete. DURF1030CT is listed as active and maintains RoHS3 compliance. Both products share fully equivalent diode configuration, voltage and current ratings, rectifier speed, and mounting/package formats with minimal mechanical distinction (isolated tab). Selection is therefore enabled strictly by status, availability, and aligned regulatory compliance certifications.

Frequently Asked Questions (FAQ)

Q1: On what basis can DURF1030CT substitute for FML-13S in this category?
A1: Substitution is based on matching diode array configuration, voltage rating, current capacity, recovery speed, package type, mounting method, and RoHS compliance.

Q2: Are there any differences in reverse recovery time or leakage between the two parts?
A2: DURF1030CT has a reverse recovery time of 45 ns versus 50 ns for FML-13S, and a lower reverse leakage current. Both meet the required fast recovery and leakage characteristics for substitution.

Q3: Is package compatibility maintained?
A3: Both devices use a TO-220-3 Full Pack through hole package; DURF1030CT specifies an "Isolated Tab" feature, but the fundamental footprint and mechanical mounting are consistent.

Q4: How does product status affect selection?
A4: FML-13S is obsolete, necessitating substitution. DURF1030CT maintains active status and regulatory compliance.

Q5: Are there any RoHS compliance differences?
A5: FML-13S is RoHS compliant. DURF1030CT is ROHS3 compliant, aligning with stricter RoHS version compliance.
