Is there a KiCad symbol and footprint for the TPD2EUSB30ADRTR?
Yes. The symbol is Power_Protection:TPD2EUSB30 and the footprint Package_TO_SOT_SMD:Texas_DRT-3, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the TPD2EUSB30ADRTR?
SOT(9x3), with 3 pins. Its footprint is drawn on this page.
Where is the TPD2EUSB30ADRTR datasheet?
TECH PUBLIC publishes it: the Datasheet link on this page opens it.
Where can I order the TPD2EUSB30ADRTR?
JLCPCB lists it as part C3011197, with 1,704 in stock; the sellers' links on this page open their listings.
What can replace the TPD2EUSB30ADRTR?
Parts like it in the library: the TPD2EUSB30ADRTR-TP by TECH PUBLIC, the H3V3LD5B by hongjiacheng, the H3V3L10B by hongjiacheng and the LESD8D3.3CAT5G by Leshan Radio (LRC). Check their datasheets: a part that fits the footprint may still differ in its ratings.
