Single Diodes Procurement Notes

Verify the specific ordering suffix to confirm packaging orientation and lead-free status. Standard production units are available in tubes, while tape and reel options exist in left or right orientations. Confirm that the component meets RoHS directives and halogen-free requirements before finalizing procurement specifications.

Single Diodes Selection Notes

Select this component for applications requiring high-frequency operation and low forward voltage drop. Ensure thermal management allows for case temperatures within limits defined by the duty cycle. Verify that the 80 V reverse voltage rating accommodates system transients and that the D2PAK footprint matches the PCB layout constraints.

Single Diodes Part Context

This part belongs to the 8TQ...S series of Schottky rectifiers from Vishay High Power Products. The series includes variants with different voltage ratings, such as the 8TQ100S. These devices are designed for general-purpose high-power applications requiring robust performance under varying thermal conditions.

Single Diodes Replacement Considerations

The 8TQ100S serves as a direct substitute offering identical current and package specifications with a higher 100 V reverse voltage rating. Ensure the application voltage does not exceed the original 80 V limit if substituting with lower-rated alternatives.
