Diode Arrays Procurement Notes

Verify the specific suffix configuration against official Vishay documentation to confirm package type and reliability grade. The HE3 suffix indicates high reliability grade compliant with AEC-Q101 standards. Ensure the ordering part number matches the required voltage rating and package variant, as suffixes may denote manufacturing lot or specific compliance variations not always evident in generic listings.

Diode Arrays Selection Notes

Select this component for designs requiring fast recovery speeds and high current handling in a compact surface-mount footprint. The dual common cathode configuration simplifies circuit layout for bridge-less PFC or synchronous rectification topologies. Verify thermal management requirements for the TO-263AB package based on the expected ambient temperature and duty cycle to ensure operation within the specified junction temperature limits.

Diode Arrays Part Context

This device belongs to the UG10BCT series of ultrafast rectifiers from Vishay. It shares the same 10 A current rating and TO-263AB package form factor as other variants in the family but differs in its 200 V blocking voltage rating. This specific voltage class targets applications where intermediate bus voltages or lower input AC rectification levels are required compared to higher voltage counterparts.

Diode Arrays Replacement Considerations

Direct substitutes include other Vishay dual common cathode ultrafast rectifiers with matching 10 A and 200 V ratings in TO-263AB packages, such as the UGB10BCTHE3 or UGB10CCTHE3, provided the voltage rating aligns with the circuit design requirements.
