Diode Arrays Procurement Notes

This component is officially classified as obsolete and is no longer in production by onsemi. Verification of availability requires checking distributor stock levels or approved substitute part numbers. Procurement should focus on compatible replacements rather than original units. Ensure that any alternative components meet the same electrical ratings and thermal requirements for successful integration.

Diode Arrays Selection Notes

Select this component only if legacy compatibility is required or if it is available from secondary markets. For new designs, consider modern equivalents with similar current and voltage ratings but improved thermal performance or availability. Verify that the TO-247AC package fits the PCB layout constraints. Confirm that the 45V reverse voltage rating provides sufficient margin for the specific application's peak inverse voltage conditions.

Diode Arrays Part Context

The MBR3045WTG belongs to the MBR series of Schottky rectifiers from onsemi, designed for high-efficiency power conversion. It is part of the SWITCHMODE family, which emphasizes low forward voltage drop to minimize power losses. This series is commonly used in industrial and consumer electronics where efficient rectification is critical. The TO-247AC package provides robust thermal dissipation capabilities suitable for medium to high-power applications.

Diode Arrays Replacement Considerations

Available substitutes include DSA60C45HB from IXYS. When replacing, verify that the substitute matches the 30A current rating, 45V voltage rating, and dual common cathode configuration. Ensure the replacement package is compatible with the existing footprint or allows for necessary design modifications.
