SMF5.0AAE from JUXING, in a SOD-123FL. 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	Cathode	passive	Cathode terminal per the PINNING table (pin 1, top view); the device is a unipolar TVS with a 200 W peak pulse power rating at TA=25°C, and its working peak reverse voltage VRWM should be equal to or greater than the DC or continuous peak operating voltage (Note 6).
2	Anode	passive	Anode terminal per the PINNING table (pin 2, top view); the package is mounted on 5 mm copper pads to each terminal per Note 2 for the stated ratings.
