Is there a KiCad symbol and footprint for the SESR70?
Yes. The symbol is EasyEDA_Cloud:CD143A-SR70 and the footprint Package_TO_SOT_SMD:SOT-143, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SESR70?
SOT-143, with 4 pins. Its footprint is drawn on this page.
Where is the SESR70 datasheet?
SEMIWARE publishes it: the Datasheet link on this page opens it.
Where can I order the SESR70?
JLCPCB lists it as part C720028, with 0 in stock; the sellers' links on this page open their listings.
What can replace the SESR70?
Parts like it in the library: the CD143A-SR70 by Bourns, the SR70 by TECH PUBLIC, the BSR70 by BORN and the SR70.TCT by SEMTECH. Check their datasheets: a part that fits the footprint may still differ in its ratings.
