Is there a KiCad symbol and footprint for the STCMB1?
Yes. The symbol is EasyEDA_Cloud:STCMB1TR and the footprint Package_SO:SOIC-20W_7.5x12.8mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the STCMB1?
SOIC-20-300mil, with 20 pins. Its footprint is drawn on this page.
Where is the STCMB1 datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the STCMB1?
JLCPCB lists it as part C472579, with 0 in stock; the sellers' links on this page open their listings.
What can replace the STCMB1?
Parts like it in the library: the UCC3895DWTR by Texas Instruments, the L4981AD013 by STMicroelectronics, the ICE2HS01G by Infineon Technologies and the HR1211GY-0001-Z by Monolithic Power Systems. Check their datasheets: a part that fits the footprint may still differ in its ratings.
