MBRB1540CT-TP Equivalent & Substitute Parts Reference

Part Overview

The MBRB1540CT-TP is a Schottky diode array featuring a dual common cathode configuration, rated for 40 V reverse voltage and 15A forward current per diode. Its surface-mount TO-263-3, D2PAK package is engineered for high-current, fast-recovery applications. The product is classified as Obsolete, which creates sourcing and availability issues for ongoing designs and maintenance. To maintain functionality and form-factor compatibility, finding substitute or equivalent diode rectifiers is necessary.

Key Parameters

Substitute Part Grouping Explanation

Substitution is performed using a parameter equivalence method. The substitute part must match the MBRB1540CT-TP in package type (TO-263-3, D2PAK (2 Leads + Tab), TO-263AB), mounting type, common cathode configuration, Schottky technology, and similar or higher voltage/current specifications. Key substitution criteria include: Voltage - DC Reverse (Vr), Current - Average Rectified (Io), Voltage - Forward (Vf), Reverse Leakage, speed rating, and device package. Compliance parameters such as REACH Status and ECCN are also matched as provided.

Parameter Comparison

Engineering Selection Recommendations

The MBRB1540CT-TP is classified as Obsolete. Selection of the recommended substitute MBRB1645CT-TP is permitted based on its Active product status, matching mounting and package, and compliance equivalency in REACH and ECCN classifications as provided.
