BZX84C56 from Yangzhou Yangjie Elec Tech, 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 zener diode, shown on the pin-1 side of the symbol on the SOT-23 outline; BZX84C56 has a nominal Vz of 56V (53V to 59V). |
| 2 | NC | unconnected | Pin 2 is drawn in the SOT-23 package diagram with no connection to the diode. |
| 3 | K | passive | Cathode of the zener diode, shown on the pin-3 side of the symbol; BZX84C56 has a nominal Vz of 56V (53V to 59V) and a maximum power dissipation of 350mW. |
