MBRF2045CT-LJ

Diode Arrays Overview

The MBRF2045CT-LJ is a Schottky Barrier Rectifier manufactured by Diodes Incorporated, designed for commercial applications. It features a dual common cathode configuration with two independent legs housed in a TO-220AB package. Each leg supports a peak repetitive reverse voltage of 45V and an average rectified output current of 10A, totaling 20A for the device. The maximum forward voltage drop is 0.64V at +25°C, with a leakage current of 0.1mA. It withstands a non-repetitive peak forward surge current of 180A and operates within a temperature range of -55°C to +150°C.

Diode Arrays Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging details, as standard tubes contain 50 pieces per tube. Confirm RoHS compliance and Halogen-free status requirements. Ensure the selected variant matches the required thermal resistance and mounting specifications for the intended circuit design.

Diode Arrays Selection Notes

Select this component for circuits requiring low forward voltage drop and high efficiency in switching applications. Consider the 45V reverse voltage rating and 10A per leg current capacity when designing power supplies or free-wheeling circuits. Evaluate thermal management needs based on the junction-to-case thermal resistance values provided in the datasheet.

Diode Arrays Part Context

This part belongs to the MBR2045CT/MBRF2045CT series of 20A Schottky Barrier Rectifiers from Diodes Incorporated. The 'F' designation indicates the TO-220AB plastic package.
