Is there a KiCad symbol and footprint for the MB8S?
Yes. The symbol is Diode_Bridge:MB8S and the footprint Package_SO:OnSemi_751EP_SOIC-4_3.9x4.725mm_P2.54mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the MB8S?
MBS, with 4 pins. Its footprint is drawn on this page.
Where is the MB8S datasheet?
MDD publishes it: the Datasheet link on this page opens it.
Where can I order the MB8S?
JLCPCB lists it as part C53079, with 16,813 in stock; the sellers' links on this page open their listings.
What can replace the MB8S?
Parts like it in the library: the MB8S by Chongqing Pingwei Tech, the MB8S by Jiangsu Changjing Electronics Technology (CJ), the MB8S by LangJie and the MB8S by Yenji Elec. Check their datasheets: a part that fits the footprint may still differ in its ratings.
