FML-G13S Equivalent & Substitute Parts Reference

Part Overview

The Sanken Electric USA Inc. FML-G13S is a general purpose diode rated at 300 V reverse voltage and 5 A average rectified current, housed in a TO-220F-2L through-hole package. This product has an obsolete status. When a diode becomes obsolete, finding equivalent and substitute rectifier models is necessary to support ongoing production, maintain legacy equipment, and ensure serviceability. Substitute parts are identified by matching critical electrical, mechanical, and compliance parameters.

Engineering Selection Recommendations

The FML-G13S diode has obsolete status, while SFAF1605G C0G and SFAF505G C0G are active. All listed substitute parts comply with RoHS and have the same MSL rating, ECCN, and HTSUS codes as FML-G13S. For compliance and continued product availability, SFAF1605G C0G and SFAF505G C0G meet essential selection criteria.

Frequently Asked Questions (FAQ)

Q1: What key electrical parameters must match for substituting a rectifier diode?
A1: The primary parameters are maximum reverse voltage, average rectified current, forward voltage drop at the rated current, recovery speed, and reverse leakage at rated voltage.

Q2: Why is package compatibility important in substitute diode selection?
A2: The package type (TO-220-2 Full Pack or equivalent full-pack style) and pinout must match to ensure mechanical and thermal compatibility with existing PCB footprints and heatsink attachments.

Q3: Are MSL and RoHS compliance important for substitution?
A3: MSL ensures correct handling during assembly, and RoHS compliance ensures environmental and legislative conformity.

Q4: What is the impact of product status on substitution?
A4: When the original product is obsolete, only active or available parts should be selected to ensure long-term supply and support.

Q5: Is it necessary to match speed and reverse recovery time when selecting substitutes?
A5: For fast recovery diodes in the same category, matching the specified speed and reverse recovery time is critical for circuit performance.
