SP0201B-ULC-01UTG from Littelfuse, 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 | Terminal 1 of the bidirectional 0201 DFN TVS diode as shown in the bottom-view pinout; the datasheet gives no pin function label, and the device-level bidirectional reverse working voltage is -7.0 V to 7.0 V. |
| 2 | 2 | passive | Terminal 2 of the bidirectional 0201 DFN TVS diode as shown in the bottom-view pinout; the datasheet gives no pin function label, and the device-level bidirectional input capacitance is 0.13 pF max. |

SP0201B-ULC-01UTG - 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)
