MBRB3045CTTRR

Diode Arrays Overview

The MBRB3045CTTRR is a dual common-cathode Schottky rectifier manufactured by Vishay General Semiconductor. It features two silicon diodes in a TO-263AB (D²PAK) package with the cathode connected to the heatsink tab. The device supports a maximum average forward current of 15 A per diode and offers reverse voltage ratings of 35 V or 45 V. Key electrical parameters include a maximum instantaneous forward voltage of 0.60 V at 20 A and a peak forward surge current capability of 200 A. The component operates within a junction temperature range of -65 °C to +150 °C.

Diode Arrays Procurement Notes

Verify that the ordering suffix matches the required packaging configuration, such as tape and reel quantities versus tube counts. Confirm whether the E3 suffix is necessary for lead-free compliance or if the HE3 suffix is required for automotive-grade reliability standards. Ensure the specific part number corresponds to the desired voltage rating variant within the product family.

Diode Arrays Selection Notes

Select this component when designing low-voltage, high-frequency rectification circuits requiring efficient power conversion. The dual common-cathode configuration allows for use in full-wave rectifiers or synchronous rectification topologies. Consider the thermal resistance characteristics and mounting requirements associated with the TO-263AB package for effective heat dissipation in high-current applications.

Diode Arrays Part Context

This component belongs to the MBR(F,B)3035CT & MBR(F,B)3045CT series from Vishay General Semiconductor. The series includes variants in TO-220AB, ITO-220AB, and TO-263AB packages. The MBRB3045CTTRR specifically denotes the TO-263AB surface-mount version with a trailing roll packing code.

Diode Arrays Replacement Considerations

Cross-reference with other Vishay Dual Common-Cathode Schottky Rectifiers in the same series. Verify pinout compatibility and thermal performance metrics before substituting.
