MBR2045CT-G1

Diode Arrays Overview

The MBR2045CT-G1 is a high-efficiency dual Schottky rectifier manufactured by Diodes Incorporated, designed for switch mode power supplies and medium voltage applications. It features a common cathode configuration with two independent diode legs housed in a TO-220-3 package. Each leg supports an average rectified forward current of 10A, totaling 20A. The device withstands a peak repetitive reverse voltage of 45V and offers a maximum instantaneous forward voltage drop of 0.65V at +25°C. It operates up to a junction temperature of +150°C and includes a guard-ring structure for stress protection.

Diode Arrays Procurement Notes

Verify the specific ordering suffix G1 confirms RoHS compliance and halogen-free status as defined by the manufacturer. Confirm the package variant matches the required thermal resistance and mechanical dimensions. Ensure the component is sourced from authorized channels to guarantee authenticity and adherence to quality standards.

Diode Arrays Selection Notes

Select this component for medium voltage, high-frequency circuits requiring low switching losses and minimal noise. Evaluate thermal management requirements based on the specified junction-to-case thermal resistance. Consider the 45V reverse voltage rating relative to the circuit's peak operating conditions to ensure adequate safety margins.

Diode Arrays Part Context

This part belongs to the MBR2045C series of high-efficiency power Schottky rectifiers. It is available in both standard plastic (TO-220-3) and flat (TO-220F-3) case configurations. The series is engineered for applications demanding low forward voltage and high reliability in power conversion environments.

Diode Arrays Replacement Considerations

Consult official substitution lists for equivalent dual Schottky rectifiers with matching 45V ratings and 10A per leg current capabilities. Verify pinout compatibility and thermal performance characteristics before implementation.

Diode Arrays FAQ

What is the maximum non-repetitive peak surge current?

The maximum non-repetitive peak surge current is 150A under half-wave, single-phase, 60Hz conditions.

Is the device suitable for automotive applications?

Standard versions are not automatically qualified for automotive use. Automotive-specific parts require qualification to AEC-Q101 and PPAP capability.

What is the typical reverse leakage current at rated DC voltage?

The maximum reverse leakage current is 0.1mA at +25°C and 15mA at +125°C when tested at the rated DC blocking voltage.
