Procurement Notes
Verify the specific ordering suffix 'L' indicates the Low Forward Voltage variant, which differs electrically from standard versions in the same series. Confirm the moisture sensitivity level and ESD classification requirements match your assembly line capabilities. Ensure the tape and reel packaging dimensions align with your pick-and-place equipment specifications before finalizing procurement orders.
Selection Notes
Select this component when a 40 V reverse voltage rating and 2 A continuous forward current are required in a small SMA footprint. The 'L' suffix denotes a lower forward voltage drop compared to non-L variants, improving efficiency in low-voltage applications. Verify that the thermal resistance and heat dissipation capabilities meet the ambient operating conditions of the target circuit design.
Part Context
This part belongs to the CD214A-B2xR series of Schottky Barrier Rectifiers designed for portable communications and computing equipment. The series addresses industry demands for miniaturization by providing silicon diodes in compact packages compatible with standard SMD processes. The DO-214AC format allows for space savings on PCB layouts while maintaining robust electrical performance for general rectification tasks.
