ESDZV5-1BU2 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 | I/O1 | passive | Bidirectional ESD-protected line terminal (pin 1, marked by pin 1 mark), with stand-off voltage VRM of 5.5 V max and 6 pF typ (7.5 pF max) line capacitance. |
| 2 | I/O2 | passive | Second terminal of the bidirectional TVS diode (pin 2), which is symmetric with pin 1 and has VRM of 5.5 V max and clamping voltage of 8 V at 8 kV IEC 61000-4-2 contact discharge. |

- Symbol:
ESDZV5-1BU2 - 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)
