FML-22S Equivalent & Substitute Parts Reference

Part Overview

The Sanken Electric USA Inc. FML-22S is a diode array featuring a 1 pair common cathode configuration, rated for 200 V reverse voltage and 10A average rectified current per diode, housed in a TO-220-3 Full Pack package for through-hole mounting. Its fast recovery speed and robust electrical characteristics suit general-purpose rectification in high-current circuits. As the FML-22S is now classified as obsolete, finding alternative diodes/rectifiers meeting identical electrical and mechanical parameters is essential to maintain legacy designs and ensure ongoing product support.

Substitute Part Grouping Explanation

Substitute and equivalent diode array models are identified strictly by matching or closely aligning these key parameters: configuration (1 pair common cathode), maximum reverse voltage (200 V), average rectified current (as close as possible to 10A per diode), forward voltage (Vf), reverse recovery time (trr), reverse leakage current, thermal ratings, through-hole mounting type, and compatible package/case (TO-220-family Full Pack). Only models explicitly designated with these characteristics are listed below.

Engineering Selection Recommendations

The primary selection driver is the obsolete status of the Sanken Electric USA Inc. FML-22S. Substitute diode and rectifier parts MURF1620CTG, FFPF10UP20STU, and RF1001T2D are listed as active products. Each substitute’s RoHS compliance status is specified; where applicable, select only parts meeting required RoHS or environmental certifications. All alternatives are through-hole, TO-220 package variants, and maintain standard product and compliance identification.

Frequently Asked Questions (FAQ)

Q: What are the critical parameters for substituting the FML-22S?
A: Diode configuration, reverse voltage rating (200 V), average rectified current, forward voltage drop, recovery speed, leakage current, mounting type, and package compatibility.

Q: Are all listed substitutes compatible with through-hole mounting?
A: Yes, all equivalents use through-hole compatible TO-220 package families.

Q: What does “1 Pair Common Cathode” mean in the configuration?
A: This denotes a dual-diode structure where both diodes share a common cathode pin, suitable for common rectifier circuits.

Q: How should differences in average rectified current and forward voltage be considered?
A: Only substitutions with identical or slightly lower current ratings are listed. Forward voltage differences are explicitly stated to ensure proper matching.

Q: Are all alternatives RoHS compliant?
A: RoHS status is detailed for each part. Only substitutes with declared RoHS compliance are identified as compliant.

Q: Are package types for all substitutes fully aligned with FML-22S?
A: All substitutes share the TO-220 body style with minor suffix variations (F, FP, FN, 2/3 pins). Pin-outs and mechanical compatibility should match the TO-220-3 Full Pack standard per the provided parameters.
