MBR40040CTL Equivalent & Substitute Parts Reference

Part Overview

The MBR40040CTL, manufactured by GeneSiC Semiconductor, is a Schottky diode module in the diodes, rectifiers category. It features a diode array in a 1 Pair Common Cathode configuration, rated at 40 V maximum DC reverse voltage and 200A average rectified current per diode. With its fast recovery characteristic and chassis mount, Twin Tower package, this module is suitable for high-current rectification applications. The MBR40040CTL is classified as obsolete, making it necessary to identify equivalent or substitute parts for ongoing designs and maintenance requirements.

Engineering Selection Recommendations

Engineering selection among these diode modules is based on product status and compliance information as provided. The MBR40040CTL is obsolete. The 400CNQ040 is active and ROHS3 compliant, with REACH affected status. Selection for ongoing or new applications should prioritize available, active, and compliant part numbers.

Frequently Asked Questions (FAQ)

Q1: What parameters are critical when substituting the MBR40040CTL in a design?
A1: Key parameters include diode configuration (1 Pair Common Cathode), Schottky technology, voltage and current ratings (40 V, 200A), forward voltage, recovery speed, mounting type, and package.

Q2: Is the 400CNQ040 mechanically and electrically compatible with the MBR40040CTL?
A2: The 400CNQ040 matches the main diode configuration, electrical ratings, and chassis mounting. Package differences (Twin Tower vs PRM4) must be considered for direct mechanical fit.

Q3: How does product status affect part selection?
A3: Since the MBR40040CTL is obsolete, preference is given to active parts such as the 400CNQ040 to ensure continued availability and manufacturer support.

Q4: What compliance considerations apply to these diode modules?
A4: 400CNQ040 is ROHS3 compliant and REACH affected. MBR40040CTL compliance status is not specified in the input.

Q5: Do speed, leakage, and temperature range vary significantly between these parts?
A5: Both parts share fast recovery time and similar operating temperature ranges. The reverse leakage current at maximum voltage is higher for the 400CNQ040 (20 mA vs 3 mA @ 40 V).

Q6: Are mounting types equivalent for replacement purposes?
A6: Both diodes are chassis mount, but the mechanical footprint (Twin Tower vs PRM4) must be verified for enclosure and heatsink compatibility.
