ESD9N12BA-ES from ElecSuper, in a DFN1006-2L. 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 | bidirectional | Connects to the IO1 line to be protected; the device is a bi-directional ESD protector, so either pin can be the signal line. |
| 2 | IO2 | bidirectional | Connects to the IO2 line to be protected; the device is a bi-directional ESD protector, so either pin can be the signal line. |
