Single Diodes Procurement Notes

Verify the specific ordering suffix (e.g., LT3G vs. LT1G) to confirm tape and reel packaging quantities, as these affect logistics handling. Confirm that the 'S' prefix is required if your application demands AEC-Q101 qualification and PPAP documentation. Ensure the selected variant matches the necessary environmental compliance requirements such as Pb-free and Halogen-free status before finalizing procurement orders.

Single Diodes Selection Notes

Select this component when a compact SOT-23 footprint is required alongside high-speed switching performance. The 100 V reverse voltage rating suits moderate voltage signal paths. Consider the 4 ns recovery time for applications demanding minimal switching delay. Verify thermal constraints against the specified junction-to-ambient resistance values for your specific PCB layout and substrate material.
