Diode Arrays Procurement Notes

Verify the specific suffix 'A/P' against the official Vishay datasheet to confirm packaging details and RoHS compliance status. Confirm availability as distribution channels may list this part as obsolete or end-of-life. Ensure the ordering code matches the exact voltage and current ratings required for the target application before procurement.

Diode Arrays Selection Notes

Select this component when a dual common cathode arrangement is required in a compact surface-mount footprint. The 200 V rating and 18 A current capacity make it suitable for low-voltage, high-current power stages. Evaluate the 30 ns reverse recovery time against the switching frequency requirements of the power converter to ensure minimal switching losses.

Diode Arrays Part Context

This part belongs to the UGB series of fast recovery rectifiers from Vishay. These devices are designed for general-purpose high-efficiency rectification in power electronics. The D2PAK-2 package provides a balance between current handling capability and board space efficiency, commonly used in consumer and industrial power adapters.

Diode Arrays Replacement Considerations

Cross-reference with other Vishay UGB series parts such as UGB18DCT/45 for identical electrical specifications. Verify pinout compatibility and thermal resistance values when substituting with equivalent components from other manufacturers to ensure reliable operation.
