Diode Arrays Procurement Notes

Verify the specific suffix E3/4W against the manufacturer's latest documentation to confirm compliance with current environmental directives, as suffixes may indicate variations in packaging or material composition. Confirm availability status, as this part number is listed as obsolete in public records. Ensure that any substitute components maintain identical pinout compatibility and thermal performance specifications for the target application.

Diode Arrays Selection Notes

Select this component when a robust surface-mount solution is required for 100 V, 10 A rectification tasks. The TO-263AB package offers superior heat dissipation compared to smaller SMD packages. Consider the 175°C junction temperature rating for high-temperature environments. Verify that the forward voltage drop meets the efficiency requirements of the specific circuit design before finalizing the selection.

Diode Arrays Part Context

This device belongs to the UB20 series of general-purpose diode arrays from Vishay. The series includes variants with different voltage ratings, such as the UB20CCT (150 V) and UB20DCT (200 V), all sharing the same 10 A current rating and TO-263AB package. These parts are designed for high-reliability applications requiring efficient surface-mount rectification solutions.

Diode Arrays Replacement Considerations

Publicly confirmed substitute part numbers include UB20BCT-E3/8W, which shares the same electrical specifications but utilizes a different packaging format.
