Is there a KiCad symbol and footprint for the ZMM5.1?
Yes. The symbol is Diode:ZMMxx 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 ZMM5.1?
SOD-80C, with 2 pins. Its footprint is drawn on this page.
Where is the ZMM5.1 datasheet?
DIOTEC publishes it: the Datasheet link on this page opens it.
Where can I order the ZMM5.1?
JLCPCB lists it as part C212781, with 0 in stock; the sellers' links on this page open their listings.
What can replace the ZMM5.1?
Parts like it in the library: the ZMM5V1 by HXY MOSFET, the ZMM5V1-MS by MSKSEMI, the ZMM5V1PF-M by STMicroelectronics and the ZMM5V1 by Slkor. Check their datasheets: a part that fits the footprint may still differ in its ratings.
