MBRB2545CTG

Diode Arrays Overview

The MBRB2545CTG is a dual Schottky barrier rectifier manufactured by onsemi, housed in a D2PAK-3 (TO-263-3) surface-mount package. It features a common cathode configuration with two silicon elements. The device supports a maximum repetitive peak reverse voltage of 45 V and an average forward rectified current of 12.5 A per diode leg. Key electrical parameters include a maximum forward voltage of 550 mV at 12.5 A and a non-repetitive peak forward surge current rating of 150 A. The component operates within a junction temperature range of -65°C to +175°C.

Diode Arrays Feature Summary

• Low forward voltage characteristic designed to minimize conduction losses and enhance overall system efficiency.
• High thermal stability enabled by a wide operating junction temperature range extending up to 175°C.
• Robust surge handling capability provided by a high peak forward surge current rating for transient protection.

Diode Arrays Applications

• Output rectification in switch-mode power supplies
• Power management circuits requiring low loss rectification
• Free-wheeling diodes in DC-DC converter topologies

Diode Arrays Procurement Notes

Verify the specific suffix against official onsemi documentation to confirm package type and compliance status. Ensure the procurement channel provides valid traceability for RoHS and REACH requirements. Confirm that the received components match the specified D2PAK-3 form factor and electrical ratings before integration into production designs.

Diode Arrays Selection Notes

Select this component when a surface-mount solution is required for 45 V applications needing 12.5 A continuous current. The D2PAK-3 package offers superior thermal dissipation compared to smaller SMD packages. Consider the 175°C junction temperature rating for high-temperature environments where standard 150°C devices may fail.

Diode Arrays Part Context

This part belongs to the MBRB series of dual Schottky barrier rectifiers from onsemi. It shares functional similarities with through-hole variants like the MBR2545CTG but utilizes a surface-mount footprint for automated assembly. The series is engineered for general-purpose rectification in power electronics where efficiency and thermal performance are critical design constraints.

Diode Arrays Replacement Considerations

Publicly confirmed substitute part numbers for MBRB2545CTG were not identified in the provided source material. Verify compatibility with alternative manufacturers by matching the 45 V reverse voltage, 12.5 A current rating, and D2PAK-3 package dimensions.
