Equivalent & Substitute Parts Reference for FMEN-430A

Part Overview

The Sanken Electric USA Inc. FMEN-430A is a Schottky diode array in the Diodes, Rectifiers category. It features a 1 pair common cathode configuration, 100 V maximum reverse voltage, and 15A average forward current per diode, housed in a TO-3P-3 Full Pack through-hole package. The product is currently active and available in inventory. Due to potential lifecycle, availability, and logistics considerations, there is a need to identify strictly parametric equivalent or substitute models matching the specified electrical and mechanical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitute or equivalent parts for Schottky diode arrays, such as the FMEN-430A, are identified exclusively by matching these key parameters:

• Diode configuration (1 pair common cathode)
• Technology (Schottky)
• Reverse voltage rating (100 V)
• Average forward current per diode (15A)
• Maximum forward voltage at rated current (850 mV @ 15A)
• Switching speed (Fast Recovery ≤ 500ns, > 200mA)
• Maximum reverse leakage current at maximum reverse voltage
• Operating junction temperature range
• Mounting type (through hole)
• Package type and supplier device package
• Regulatory compliance (RoHS, MSL, ECCN, and HTSUS where applicable)

Parameter Comparison

Engineering Selection Recommendations

FMEN-430A is designated as active and RoHS compliant, with an unlimited moisture sensitivity level (MSL 1). The substitute part, FST30100, matches key electrical and mechanical parameters but is marked obsolete, limiting its use in new designs. Both parts are compliant with RoHS and ECCN regulations, and share the same harmonized tariff schedule code.

Frequently Asked Questions (FAQ)

Q: What are the critical parameters when selecting an equivalent or substitute for FMEN-430A?
A: Selection requires matching diode configuration, technology, maximum reverse voltage, average rectified current, forward voltage at rated current, switching speed, reverse leakage current, operating junction temperature, mounting type, package type, and regulatory compliance.

Q: Can FST30100 be used as a direct substitute for FMEN-430A?
A: FST30100 provides the same core electrical and mounting specifications. Users must verify product status and supply chain availability since it is categorized as obsolete.

Q: Are there differences in package between FMEN-430A and FST30100?
A: Both parts share the TO-3P-3 Full Pack case, though the supplier device package designation differs (TO-3PF vs. TO-247AD). Only the explicitly stated package details are presented.

Q: How does RoHS and MSL compliance affect part selection?
A: Both FMEN-430A and FST30100 are RoHS compliant and rated MSL 1, supporting standard compliance and unlimited floor life in processing environments.

Q: Is there any difference in reverse leakage current between the two parts?
A: FMEN-430A has a specified reverse leakage current of 300 µA at 100 V, while FST30100 is specified at 500 µA at 100 V. This parameter must be compared against application requirements for compatibility.
