BZX84C30Q-7-F from Diodes Incorporated, 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 | A | passive | Anode of the zener diode, the bottom-left terminal in the top-view device schematic, which runs to the zener junction. |
| 2 | NC | unconnected | No internal connection; the bottom-right terminal in the device schematic is drawn with no connection to the diode. |
| 3 | K | passive | Cathode of the zener diode, the single top terminal in the device schematic, connected to the cathode (bar) side of the zener, which is the 28.0V to 32.0V VZ side at IZT = 2.0mA for the BZX84C30. |
