Single Diodes Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging quantity and reel diameter specifications. Ensure that the component selection aligns with the required voltage ratings and thermal management constraints for the intended circuit environment before finalizing procurement.

Single Diodes Selection Notes

Select this component when high-frequency switching efficiency and elevated temperature operation are critical requirements. The DO-214AA footprint provides a compact solution for space-constrained designs. Confirm that the 200 V reverse voltage rating exceeds the maximum expected transient voltages in the application circuit to ensure long-term reliability.

Single Diodes Part Context

This part belongs to the UH2B, UH2C, and UH2D series of surface mount ultrafast rectifiers manufactured by Vishay General Semiconductor. The series shares common mechanical and thermal characteristics while differing primarily in their maximum repetitive peak reverse voltage ratings. The UH2D variant specifically addresses applications requiring a 200 V blocking capability.

Single Diodes Replacement Considerations

Direct substitutes within the same series include UH2B-E3/5BT and UH2C-E3/5BT, which offer lower voltage ratings of 100 V and 150 V respectively. Verify that the reduced voltage ratings of these alternatives remain sufficient for the specific circuit operating conditions.
