MBRB2045CT-E3/45

Diode Arrays Overview

The MBRB2045CT-E3/45 is a dual common cathode Schottky rectifier manufactured by Vishay General Semiconductor. It utilizes silicon technology and is housed in a D2PAK (TO-263AB) surface-mount package. The device features a maximum repetitive peak reverse voltage of 45 V and provides a total maximum average forward rectified current of 20 A, with 10 A per diode. Key electrical characteristics include a peak forward surge current of 150 A per diode and a maximum instantaneous forward voltage ranging from 0.65 V to 0.84 V depending on the test conditions. The component operates within a junction temperature range of -65 °C to +150 °C.

Diode Arrays Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm compliance requirements. The E3 suffix indicates RoHS compliance and commercial grade status. Confirm that the D2PAK package variant matches the intended PCB layout and thermal management strategy. Ensure the selected component meets the required automotive or industrial qualification standards if applicable to the final assembly.

Diode Arrays Selection Notes

Select this component when a dual common cathode configuration is required for space-constrained designs. The D2PAK package offers efficient heat dissipation compared to through-hole alternatives. Evaluate the forward voltage drop at the expected operating current to ensure system efficiency targets are met. Consider the thermal resistance from junction to case when designing the heatsinking solution for continuous operation.

Diode Arrays Part Context

This part belongs to the MBRB20xxCT series of dual common cathode Schottky rectifiers from Vishay. The series includes variants with different reverse voltage ratings, such as 60 V options. The MBRB designation specifically identifies the surface-mount D2PAK package version, distinguishing it from the through-hole MBRF series. These devices are designed for general-purpose rectification in modern power electronics.
