Single Diodes Procurement Notes

Verify the specific ordering suffix against official documentation before procurement. Confirm that the component meets RoHS compliance and halogen-free requirements as specified in the datasheet. Ensure the delivery mode matches the required tape and reel quantity. Validate thermal resistance characteristics against the application's heat dissipation needs.

Single Diodes Selection Notes

Select this component when a low forward voltage drop is critical for minimizing power losses in high-frequency applications. Consider the 20 A average current rating and 45 V reverse voltage limits relative to the circuit design. Evaluate the thermal performance using the provided junction-to-case and junction-to-ambient thermal resistance values to ensure reliable operation within the specified temperature range.
