MBRF2045CT-E3/45

Diode Arrays Overview

The MBRF2045CT-E3/45 is a dual common cathode Schottky rectifier manufactured by Vishay General Semiconductor - Diodes Division. It utilizes an ITO-220AB package and features a maximum repetitive peak reverse voltage of 45 V with a total average forward rectified current of 20 A (10 A per diode). The device exhibits a low forward voltage drop, reaching a maximum of 0.80 V at 10 A and 25 °C, alongside a high peak forward surge current capability of 150 A per diode. Operating junction temperatures range from -65 °C to +150 °C.

Diode Arrays Feature Summary

Diode Arrays Procurement Notes

Verify the specific ordering suffix against official documentation to confirm compliance requirements. The E3 suffix indicates RoHS-compliant commercial grade material categorization. Confirm that the ITO-220AB package matches the intended mechanical footprint and thermal management strategy for the target assembly process.

Diode Arrays Selection Notes

Select this component when a dual common cathode configuration is required for synchronous rectification or free-wheeling paths. Ensure the 45 V reverse voltage rating accommodates system transients. Evaluate thermal resistance characteristics relative to the heatsink interface, as the ITO-220AB package relies on case temperature for derating calculations.
