MBRF40020 Equivalent & Substitute Parts Reference

Part Overview

The MBRF40020 from GeneSiC Semiconductor is a Schottky diode array (1 pair common cathode) in a TO-244AB chassis mount package, rated for 20 V maximum DC reverse voltage and 200A average rectified current per diode. It features fast recovery performance (≤500 ns at >200 mA), a forward voltage of 700 mV at 200A, and maximum reverse leakage of 1 mA at 20V. The part is currently marked as "Obsolete."
Due to its obsolete status, it is necessary to identify functionally compatible substitutes within the Diodes, Rectifiers category to ensure ongoing system maintenance and design continuity.

Substitute Part Grouping Explanation

Substitute parts are grouped based strictly on matching configuration, technology, electrical performance, and mounting characteristics. The following key parameters determine equivalence within the Diodes, Rectifiers category:

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max)
• Current - Average Rectified (Io) (per Diode)
• Voltage - Forward (Vf) (Max) @ If
• Speed (Fast Recovery ≤500ns)
• Current - Reverse Leakage @ Vr
• Operating Temperature - Junction
• Mounting Type
• Package / Case
• MSL rating, ECCN, and HTSUS

Engineering Selection Recommendations

Selection decisions based on provided parameters can reference the following:

• The MBRF40020 is obsolete; MBRT200200 is listed as active in the same category
• Both parts align in technology and configuration and share similar compliance information (MSL 1, ECCN EAR99, HTSUS 8541.10.0080)
• Only parameters explicitly provided should be considered; additional factors must not be introduced

Frequently Asked Questions (FAQ)

Q1: How are equivalent rectifier diode substitutes determined?
A1: Equivalent substitutes are determined by matching diode configuration, technology type, major electrical parameters (reverse voltage, average rectified current, forward voltage, recovery speed, and reverse leakage), mounting type, package, and compliance attributes.

Q2: What are the primary compatibility criteria for substituting MBRF40020?
A2: The primary criteria include matching Schottky technology, 1 pair common cathode configuration, suitable voltage and current ratings, recovery speed, reverse leakage, compatible operating temperature range, and identical or functionally compatible mounting and package types.

Q3: Does the package or mounting type affect interchangeability?
A3: Substitution compatibility requires that mounting type and package or case specified in the key parameters align or are compatible as per the provided attributes.

Q4: Is compliance information relevant to selecting substitutes in this category?
A4: Yes, attributes such as Moisture Sensitivity Level (MSL), ECCN, and HTSUS are relevant as they impact logistics and regulatory acceptance, as provided in the parameter list.

Q5: Can parts with different voltage and current ratings be considered equivalents?
A5: Only parts aligning with the provided key parameters should be considered. Substitution is limited to parts listed with explicit parameter compatibility.
