MBRB1545CT

Diode Arrays Overview

The MBRB1545CT is a dual common cathode Schottky rectifier manufactured by Vishay General Semiconductor. It features a D2PAK (TO-263) surface-mount package with the base connected to the common cathode. The device provides a maximum average forward current of 15 A and a maximum repetitive peak reverse voltage of 45 V. Key electrical characteristics include a maximum forward voltage drop of 0.84 V at 15 A and 25 °C, and a maximum instantaneous reverse current of 15 mA at 125 °C. The component supports junction temperatures up to 150 °C.

Diode Arrays Feature Summary

• Optimized for low reverse leakage current at elevated temperatures using proprietary barrier technology
• Guard ring structure designed to enhance ruggedness and ensure long-term reliability under overvoltage conditions
• High purity, high temperature epoxy encapsulation provides enhanced mechanical strength and moisture resistance

Diode Arrays Applications

• Switching power supply converters
• Freewheeling diodes in inductive load circuits
• Reverse battery protection systems

Diode Arrays Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact package type and reel orientation. The datasheet indicates that suffixes such as 'TRL' denote left-oriented tape and reel packaging for the D2PAK case, while 'TRR' denotes right-oriented. Confirm lead-free status requirements if applicable, as suffixes like 'PbF' or 'P' specify this attribute. Ensure the selected variant matches the required mounting configuration.

Diode Arrays Selection Notes

Select this component for applications requiring efficient high-frequency rectification with minimal forward voltage drop. The D2PAK package offers a thermal resistance of 3.0 °C/W from junction to case per leg, suitable for moderate power dissipation without extensive heatsinking. Verify that the circuit's peak reverse voltage does not exceed the 45 V rating and that the average forward current remains within the 15 A limit at the expected operating case temperature.

Diode Arrays Part Context

This part belongs to the MBRB15..CT series of center tap Schottky rectifiers from Vishay High Power Products. The series includes variants with different voltage ratings, such as the 35 V rated MBRB1535CT. The MBRB1545CT specifically utilizes the D2PAK surface-mount footprint, distinguishing it from the through-hole TO-262 packaged MBR1545CT-1 variant within the same product family.

Diode Arrays Replacement Considerations

The MBR1545CT-1 serves as a pin-compatible alternative within the same Vishay family, utilizing a TO-262 through-hole package instead of the D2PAK surface-mount form factor. Cross-referencing with other manufacturers requires verifying identical current, voltage, and thermal specifications.
