BZX84B9V1 from POPPULA, 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 9.1 V zener (nominal Vz 9.1 V, 8.92 to 9.28 V at IZT = 5 mA); connects to the diode symbol via the left bottom pin in the top-view drawing. |
| 2 | NC | unconnected | No internal connection; the right bottom pin in the top-view pin configuration drawing is not wired to the diode symbol. |
| 3 | K | passive | Cathode of the zener diode, the single top pin in the top-view drawing; 350 mW power dissipation, -55 to 150 °C operating and storage temperature. |
