Single Diodes Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact package type and delivery mode. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer before placing orders. Ensure thermal management requirements align with the specified thermal resistance values.

Single Diodes Selection Notes

Select this component for circuits requiring fast switching speeds and low reverse recovery charge. Evaluate the thermal resistance and derating curves to ensure adequate heat dissipation under continuous load conditions. Verify that the operating voltage and current ratings exceed the circuit's maximum expected peaks to maintain reliability.

Single Diodes Part Context

This part belongs to the UH(B)10FT series of ultrafast recovery rectifiers from Vishay. The series includes variants such as the UHB10FT, which shares similar electrical characteristics but utilizes a different surface-mount package (TO-263AB). Both variants are designed for high-efficiency power conversion applications.

Single Diodes Replacement Considerations

The UHB10FT-E3/4W is a pin-compatible alternative offering identical electrical specifications in a TO-263AB surface-mount package. Verify footprint compatibility and mounting torque requirements when substituting between through-hole and surface-mount versions.
