ESDZV18-1BF4
Public Made by Adomby adom
STMicroelectronics ESD And Surge Protection (TVS/ESD), 0201. Unpolarised two-terminal part: the datasheet prints no pin numbers, so pins 1 and 2 follow the library convention, KiCad symbol/footprint/3D.
Made with kicad-footprint-generator 10.0 · KiCad file format 20260206

ESDZV18-1BF4 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 | IO1 | passive | Bidirectional TVS terminal marked by the dot (pin 1) that connects to the protected line; the device triggers above 18 V min VTrig and has 3 pF typical line capacitance. |
| 2 | IO2 | passive | Second bidirectional TVS terminal, connected to ground or the opposite side of the protected line, with stand-off IRM of 100 nA max at VRM = 16 V. |
