BZX84C3V3A from Shandong Jingdao Microelectronics, 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 (Suffix A), shown connected to the diode in the page 1 schematic. |
| 2 | NC | unconnected | Not connected internally in the Suffix A single-diode schematic. |
| 3 | K | passive | Cathode of the single Zener diode (Suffix A), with a nominal Zener voltage of 3.3 V at 5 mA for the BZX84C3V3A. |
