Is there a KiCad symbol and footprint for the CDLL5521D?
Yes. The symbol is Device:D_Zener and the footprint Diode_SMD:D_MiniMELF, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the CDLL5521D?
DO-213AA, with 2 pins. Its footprint is drawn on this page.
Where is the CDLL5521D datasheet?
Microchip Technology publishes it: the Datasheet link on this page opens it.
Where can I order the CDLL5521D?
JLCPCB lists it as part C7228433, with 0 in stock; the sellers' links on this page open their listings.
What can replace the CDLL5521D?
Parts like it in the library: the ZMM4V3 by HXY MOSFET, the ZMM4V3 by JSMSEMI, the ZMM4V3 by YONGYUTAI and the BZV55C4V3 by LGE. Check their datasheets: a part that fits the footprint may still differ in its ratings.
