ESDAULC45-1BF4 from STMicroelectronics, 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 | Pin 1 | passive | Pin 1 is marked by the bar on the package and is the orientation reference for placement, per the footprint and marking figures; the datasheet gives no separate electrical function or limit for this terminal. |
| 2 | Pin 2 | passive | Pin 2 is the second terminal of this bidirectional single-line ESD protection diode shown in the 0201 footprint; the datasheet gives no separate electrical function or limit for this terminal. |

CAD (KiCad official)
- Symbol:
ESDAULC45-1BF4 - 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)
