H12VNT2U from hongjiacheng, in a SOT-23. 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 | One terminal of the uni-directional 12V ESD protection diode; junction capacitance measured Pin 1 to Pin 2 is 60pF typ and 90pF max at VR=0V, f=1MHz. |
| 2 | Pin 2 | passive | Other terminal of the uni-directional ESD diode, paired with Pin 1 for the 60pF typ / 90pF max junction capacitance at VR=0V, f=1MHz. |
| 3 | Pin 3 | passive | Shown as a third pin in the function diagram, but the datasheet does not state its function, polarity or connection. |
