MBRF50045R Equivalent & Substitute Parts Reference

Part Overview

The MBRF50045R from GeneSiC Semiconductor is a Schottky diode array in the Diodes, Rectifiers category, providing a 1 pair common anode configuration with a maximum reverse voltage of 45 V and an average rectified current per diode of 250A. The device uses fast recovery Schottky technology with a forward voltage of 750 mV at 250A, housed in a TO-244AB chassis mount package. The product status is classified as Obsolete, making it essential for engineers to identify equivalent or substitute models that match its critical electrical and mechanical parameters to maintain system compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute selection is based strictly on identical or compatible values in the following parameters: diode configuration, technology, maximum reverse voltage, speed, mounting type, and operating temperature range. Only devices matching the 1 pair common anode arrangement, Schottky fast-recovery technology, 45 V maximum reverse voltage rating, and chassis mounting with equivalent temperature tolerances are considered valid substitutes.

Parameter Comparison

Engineering Selection Recommendations

Selection is guided by product status and the moisture sensitivity level (MSL), as these dictate availability and reliability standards. The MBRF50045R is classified as Obsolete, while the MBRT30045R remains Active, both featuring MSL 1 (Unlimited), supporting standard storage and handling procedures. Compliance information, such as ECCN and HTSUS codes, remains consistent across both parts.

Frequently Asked Questions (FAQ)

Q1: What are the essential criteria for substituting MBRF50045R with MBRT30045R?
A1: Substitution criteria include matching diode configuration (1 pair common anode), Schottky technology, 45 V maximum reverse voltage, fast recovery speed, chassis mount, and compatible operating temperature ranges.

Q2: Are the package or mounting differences significant for substitution?
A2: Both devices use chassis mounting, though the package differs (TO-244AB vs. Three Tower). Engineers should verify dimensional and mechanical compatibility based on exact mounting requirements.

Q3: How does the average rectified current rating impact substitute suitability?
A3: The MBRF50045R is rated for 250A, while the MBRT30045R is rated for 150A per diode. Ensure system requirements do not exceed the substitute's current rating.

Q4: Do both parts share the same compliance and MSL status?
A4: Both parts have an MSL of 1 (Unlimited), supporting unrestricted storage and handling conditions.

Q5: Is there any difference in reverse leakage current specifications?
A5: The main part is rated at 1 mA @ 45 V, while the substitute specifies 1 mA @ 20 V. Review system operating voltages accordingly.
