Equivalent & Substitute Parts for MBRTA80045

Part Overview

The MBRTA80045, manufactured by GeneSiC Semiconductor, is a diode array featuring a 1 pair common cathode Schottky technology configuration. It supports a reverse voltage of 45 V and a rectified current of 400 A per diode, housed in a Three Tower chassis mount package. As the product status is marked "Obsolete," sourcing direct replacements is necessary to maintain design continuity and replace existing inventory in applications requiring the specified electrical and mechanical properties.

Key Parameters

Substitute Part Grouping Explanation

Substitute candidates must match the following key parameters explicitly:

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 45 V
• Current - Average Rectified (Io) (per Diode): 400A
• Speed: Fast Recovery =< 500ns, > 200mA (Io)
• Mounting Type: Chassis Mount
• Package / Case: Must match application requirements as provided

Substitution is strictly performed based on matching these parameters. No additional electrical, mechanical, or compliance data beyond those listed are considered.

Parameter Comparison

Engineering Selection Recommendations

Selection of VS-400CNQ045PBF as a substitute component is based on the product’s active status and the matching parameters as specified. The main part, MBRTA80045, is classified as "Obsolete," making substitution necessary for continued design support and inventory fulfillment within systems requiring these defined characteristics. All substitute relationships are strictly limited to components with explicitly provided matching electrical and mechanical parameters.

Frequently Asked Questions (FAQ)

Q1: What are the most critical parameters for substituting MBRTA80045?
A1: Diode configuration (1 pair common cathode), Schottky technology, reverse voltage rating (45 V), current rating (400A), speed (fast recovery =< 500ns), mounting type (chassis mount), and package are the critical criteria.

Q2: Is package equivalence mandatory when selecting a substitute?
A2: The substitute part must meet application requirements for mounting type and package/case. Both MBRTA80045 and VS-400CNQ045PBF are chassis mount, but utilize different package styles (Three Tower vs. TO-244AB), which must be verified for form, fit, and function compatibility based strictly on provided parameters.

Q3: Are there electrical performance differences between MBRTA80045 and VS-400CNQ045PBF?
A3: The voltage - forward (Vf) @ If and reverse leakage current @ Vr differ as specified in the comparison table. Evaluation for compatibility should be made strictly on these explicit values.

Q4: Why is substitution required for MBRTA80045?
A4: MBRTA80045 has an obsolete product status, necessitating the use of substitute parts with equivalent electrical and mechanical specifications within the Diodes, Rectifiers category.

Q5: How does product status affect engineering selection?
A5: Only active status components should be considered to ensure supply continuity beyond existing obsolete inventory.
