MBRF40030 Equivalent & Substitute Parts Reference

Part Overview

The MBRF40030 is a Schottky diode module manufactured by GeneSiC Semiconductor, designed as a diode array with a 1 Pair Common Cathode configuration, a maximum DC reverse voltage of 30 V, and an average rectified current rating of 200 A per diode. This device is housed in a TO-244AB chassis mount package and supports fast recovery operation. The diode is currently classified as obsolete, making it necessary to identify alternative parts that conform to its critical electrical and mechanical parameters for continued design support and maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MBRF40030 are identified strictly based on matching and allowing for equivalent or better values of the following parameters: diode configuration (1 Pair Common Cathode), technology (Schottky), maximum DC reverse voltage (30 V), package/case (TO-244AB), mounting type (Chassis Mount), speed (Fast Recovery <= 500ns, >200mA Io), and operating temperature range (-55°C ~ 150°C). These parameters are essential to ensure mechanical fit and electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

MBRF40030 is currently obsolete. The substitute part 440CNQ030 from Vishay General Semiconductor - Diodes Division is also obsolete but is available as new original stock. Both parts carry the same product category (Diodes, Rectifiers), identical mechanical and mounting configurations, and comply with Moisture Sensitivity Level 1 (Unlimited) and ECCN EAR99. RoHS3 and REACH status are specified for the substitute only where available; no contradictory compliance information is given. Selection between these parts should be based on procurement availability, compliance status, and fit within the specified parameters.

Frequently Asked Questions (FAQ)

Q1: What are the most critical substitution criteria for MBRF40030 in the Diodes, Rectifiers category?
A1: The most critical criteria are diode configuration (1 Pair Common Cathode), maximum DC reverse voltage (30 V), Schottky technology, mounting type (Chassis Mount), package type (TO-244AB), and equivalent or higher average rectified current rating.

Q2: Are the MBRF40030 and 440CNQ030 mechanically interchangeable?
A2: Both parts specify the same package/case (TO-244AB) and mounting type (Chassis Mount), ensuring mechanical interchangeability within the constraints of this package standard.

Q3: What compliance levels should be considered when selecting a substitute part?
A3: Moisture Sensitivity Level (MSL) and ECCN designations are provided for both parts. RoHS3 and REACH compliance are specified for the substitute where available; selection should consider documented compliance status.

Q4: Are there any package or mounting constraints with these substitutes?
A4: Both MBRF40030 and 440CNQ030 utilize the TO-244AB chassis mount package, so there are no package or mounting differences based on supplied information.

Q5: Does the reverse leakage current or forward voltage differ significantly between these parts?
A5: The main and substitute parts have specified current and voltage parameters at different test values; these details should be compared directly based on provided specifications for application-critical decisions.
