FML-G12S Equivalent & Substitute Parts – Diodes, Rectifiers
Part Overview
The Sanken Electric USA Inc. FML-G12S is a general-purpose standard diode in the Diodes, Rectifiers category. It features a maximum DC reverse voltage of 200 V and a current rating of 5A, with fast recovery performance (trr: 40 ns). Packaged in a TO-220F-2L through-hole case, it is suitable for various power rectification tasks.
This product is listed as Obsolete, making the identification of equivalent and substitute parts necessary to ensure continued supply and maintenance for applications that rely on the FML-G12S form, fit, and functional characteristics.

Engineering Selection Recommendations
The FML-G12S is designated as Obsolete. Substitute models (SFAF2004GHC0G, STTH1502FP, STTH802FP) are all currently Active and meet RoHS requirements. All substitute diodes share equivalent or superior electrical ratings and packaging form factors. Product status and compliance should be the deciding factors when selecting an alternative.
Frequently Asked Questions (FAQ)
Q: What criteria are used to determine acceptable substitute diodes for the FML-G12S?
A: Acceptable substitutes must match or exceed the voltage and current ratings, offer similar or better forward voltage drop and reverse recovery time, conform to through-hole mounting requirements, and share the TO-220-2 Full Pack or equivalent package.
Q: Are the pinouts and package formats of substitutes compatible with the FML-G12S?
A: Substitute parts are specified in the TO-220-2 Full Pack (or closely compatible TO-220 family/layout) package, supporting direct mechanical and PCB replacement, provided the specific package variations (such as tab isolation) are considered in final assembly.
Q: Do substitute parts require reevaluation of environmental or compliance status?
A: All substitute parts meet RoHS compliance and have Moisture Sensitivity Level (MSL) 1 (Unlimited), aligning with modern environmental and manufacturing standards.
Q: Can substitute parts handle the same or greater electrical load as the FML-G12S?
A: All listed substitute parts have equal or higher DC reverse voltage and average rectified current ratings, confirming suitability for at least the same load as the FML-G12S.
Q: What should be considered regarding operating temperature?
A: Substitute parts offer equal or extended operating junction temperature ranges, ensuring compatibility within or beyond the original specifications.
