MBRF20040R Equivalent & Substitute Parts Reference

Part Overview

The GeneSiC Semiconductor MBRF20040R is a Schottky diode array in a 1 Pair Common Anode configuration, rated for 40 V maximum DC reverse voltage and 100A average rectified current per diode. It features fast recovery, a low forward voltage drop, chassis mount TO-244AB package, and is suitable for high-current rectification applications. The product is obsolete, making the identification of alternative or substitute models necessary for ongoing designs, manufacturing, and maintenance.

Engineering Selection Recommendations

Selection between MBRF20040R and MBRT12040R should be based on current product status. MBRF20040R is designated obsolete, whereas MBRT12040R is active and RoHS compliant. Compliance information such as RoHS status and ECCN details are provided for both parts in the input.

Frequently Asked Questions (FAQ)

Q1: What are the main criteria for substituting the MBRF20040R?
A1: Substitution is based on matching technology (Schottky), diode configuration (1 Pair Common Anode), maximum reverse voltage (40 V), fast recovery speed, operating temperature range, mounting type, and package compatibility.

Q2: Can MBRT12040R replace MBRF20040R in all applications?
A2: MBRT12040R matches key electrical characteristics such as technology, reverse voltage, speed, and configuration but differs in maximum average rectified current and package/case style.

Q3: Is package compatibility mandatory for substitution?
A3: Yes, mechanical mounting and package/case type (TO-244AB vs. Three Tower) must be compatible with existing hardware requirements.

Q4: Are compliance and status considerations relevant for selection?
A4: Yes. MBRF20040R is obsolete, while MBRT12040R is active and RoHS compliant, which affects long-term availability and environmental compliance.
