UG2GA from Yangzhou Yangjie Elec Tech, in a SMA(DO-214AC). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	K	passive	Cathode terminal, marked by the cathode line on the package body; the UG2GA blocks up to VRRM 400 V and conducts forward current up to IO 2.0 A.
2	A	passive	Anode terminal at the end opposite the cathode line; forward voltage drop is at most 1.25 V at IFM 2.0 A for the UG2GA.
