1 Channel 30KV ESD Protection Diode with Low Clamping Voltage
The ESD351DPY is an uncategorised made by Texas Instruments in a DFN2 package with 2 pins. 1 Channel 30KV ESD Protection Diode with Low Clamping Voltage.
PCBKit's library has its KiCad symbol (Diodes:Diode ESD, from CERN's library) and its footprint (ICs And Semiconductors SMD:DFN100X60X50-2N, from CERN's library), ready for a KiCad board. 1 open-source board in 1 repository on GitHub use it.

Yes. The symbol is Diodes:Diode ESD and the footprint ICs And Semiconductors SMD:DFN100X60X50-2N, both drawn on this page. PCBKit places them on a board for you when you design with it.
DFN2, with 2 pins. Its footprint is drawn on this page.
Parts like it in the library: the BAS16LP by Diodes Incorporated, the BAS3010S-02LRH by Infineon Technologies, the ESD5V3L1U-02LRH by Infineon Technologies and the SP0402B-ELC-01E by Littelfuse. Check their datasheets: a part that fits the footprint may still differ in its ratings.
