BZX84C33A 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), 33V nominal zener voltage (BZX84C33A), 350mW max total power dissipation. |
| 2 | NC | unconnected | Not connected internally in the Suffix A single-diode version; the internal diagram shows no die connection to this pin. |
| 3 | K | passive | Cathode of the single zener diode (Suffix A), 33V nominal zener voltage, operating and storage temperature range -55 to +150 °C. |
