BZX84C30A 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), connected through the diode to pin 3 (cathode); Ptot max 350 mW, Tj/Tstg -55 to +150 °C. |
| 2 | NC | unconnected | Not connected internally in the Suffix A single-diode version; the package drawing shows no internal connection to this pin. |
| 3 | K | passive | Cathode of the single zener diode (Suffix A); BZX84C30A zener voltage is 30 V nominal (28 V to 32 V) at IZT = 5 mA. |
