Diode Arrays Procurement Notes

Verify the specific package type required for the design, as the base part number covers both TO-220AB (U16DCT) and TO-263AB (UB16DCT). Confirm that the E3 suffix aligns with consumer grade requirements and RoHS compliance standards. Ensure the ordering code matches the desired delivery mode, such as tube or tape and reel, to match manufacturing processes.

Diode Arrays Selection Notes

Select this component for applications requiring fast switching speeds and low reverse recovery charge. The dual common-cathode configuration simplifies circuit layout for synchronous rectification or bridge applications. Consider thermal management strategies based on the specified thermal resistance and derating curves for continuous operation above ambient temperatures.

Diode Arrays Part Context

This component belongs to the U(B)16BCT through U(B)16DCT series of dual common-cathode ultrafast plastic rectifiers from Vishay. The series offers varying reverse voltage ratings, with the DCT variant providing the highest rating of 200 V. These devices are designed for efficiency in modern power conversion systems where rapid switching and low loss are critical performance factors.

Diode Arrays Replacement Considerations

Direct substitutes within the same voltage and current ratings include the UB16CCT-E3/4W (150 V) and UB16BCT-E3/4W (100 V), provided the lower voltage ratings meet the circuit requirements. Verify pinout compatibility and thermal characteristics when cross-referencing with other manufacturers' ultrafast rectifiers.
