BZX84C15W from Changjing, in a SOT-323. 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 (pin 1 in the symbol on page 1); forward voltage is 0.9 V at IF = 10 mA. |
| 2 | NC | unconnected | No connection; pin 2 is shown as an open, unconnected terminal in the page 1 symbol. |
| 3 | K | passive | Cathode of the zener diode (pin 3 in the symbol on page 1); nominal zener voltage is 15 V (13.8 V to 15.6 V) at IZT = 5 mA. |
