MBRB3045CT-M3/I

Diode Arrays Overview

The MBRB3045CT-M3/I is a dual common cathode Schottky rectifier manufactured by Vishay General Semiconductor. It utilizes the D2PAK (TO-263AB) surface-mount package and features a guardring for overvoltage protection. The device supports a maximum repetitive peak reverse voltage of 45 V and provides a total maximum average forward rectified current of 30 A, with 15 A per diode. It exhibits a low forward voltage drop of 0.60 V at 20 A and 125 °C, alongside a high forward surge capability of 200 A per diode. The component operates within a junction temperature range of -65 °C to +150 °C.

Diode Arrays Feature Summary

• Guardring structure designed for enhanced overvoltage protection
• Low forward voltage drop contributing to high efficiency and reduced power loss
• High forward surge current capability suitable for demanding transient loads
• AEC-Q101 qualified for automotive reliability standards

Diode Arrays Applications

• Low voltage, high frequency rectification in switching mode power supplies
• Freewheeling diodes in DC/DC converter circuits
• Polarity protection applications

Diode Arrays Procurement Notes

Verify the specific ordering suffix against official documentation to confirm compliance status. The M3 suffix indicates RoHS-compliant, halogen-free commercial grade material that meets JESD 201 class 1A whisker test requirements. Confirm the delivery mode matches the required quantity, as this variant is supplied in tape and reel packaging.

Diode Arrays Selection Notes

Select this component when a dual common cathode configuration is required for synchronous rectification or polarity protection. Ensure the application voltage does not exceed the 45 V rating and verify thermal management capabilities, as the device dissipates heat through the exposed pad. Consider the 150 °C maximum junction temperature limit for high-temperature environments.

Diode Arrays Part Context

This part belongs to the MBRB series of Dual Common Cathode Schottky Rectifiers from Vishay. The series is characterized by its Power Pack construction and suitability for high-frequency operation. The MBRB3045CT specifically targets applications requiring robust performance in compact surface-mount footprints.

Diode Arrays Replacement Considerations

Vishay offers the HM3 variant (MBRB3045CT-HM3/I), which shares identical electrical specifications but meets AEC-Q101 qualification and passes the JESD 201 class 2 whisker test.
