Single Diodes Procurement Notes

Verify the specific ordering code suffix to confirm packaging configuration, as the '-18' designation indicates units per reel. Confirm AEC-Q101 qualification status if automotive grade reliability is required, as this may necessitate a different part number. Ensure the selected component matches the required tape and reel dimensions for automated assembly equipment.

Single Diodes Selection Notes

Select this component when a low forward voltage drop and rapid reverse recovery are critical for circuit performance. The SOD-123 package offers a compact footprint suitable for space-constrained designs. Consider the thermal resistance values when designing heat dissipation strategies for high ambient temperatures or dense PCB layouts.
