PESD0201B12 from YFW, in a 0201. 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	1	passive	Bi-directional ESD protection terminal, connects to the signal line to be protected (12.0 V max continuous operating voltage, 15 kV air / 8 kV contact IEC 61000-4-2).
2	2	passive	Bi-directional ESD protection terminal, connects to ground in the typical application; the device is symmetric and either terminal may be used (12.0 V max continuous operating voltage).

Symbol: PESD0201B12
Footprint: Diode_SMD:D_0201_0603Metric
3D model: 0201, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.3 mm nominal 01005 height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
3D model files: pesd0201b12-etched.step / pesd0201b12-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); pesd0201b12.step / pesd0201b12.glb are the bare package body.
