BZX84C3V3_R1_00001 from PANJIT International, 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 single Zener diode, shown on the package diagram at pin 1 (BZX84C3V3 nominal Vz 3.3V, 3.14 to 3.47V at 5.0 mA). |
| 2 | NC | unconnected | No internal connection; pin 2 is drawn without any connection to the diode in the SINGLE package diagram. |
| 3 | K | passive | Cathode of the single Zener diode, connected to the bar of the diode symbol at pin 3 in the package diagram. |
