BZX84C3V0T-7-F from Diodes Incorporated, in a SOT-523. 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, shown at the bottom-left terminal of the device schematic. |
| 2 | NC | unconnected | No internal connection; the bottom-right terminal in the device schematic is not connected to the diode. |
| 3 | K | passive | Cathode of the Zener diode, shown at the single top terminal of the device schematic (3.0V nominal, 2.8V to 3.2V at IZT = 5mA). |
