BZX84C10W-7-F from Diodes Incorporated, 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, shown as the bottom-left lead in the device schematic; the 10V Zener (VZ 9.4V to 10.6V at IZT = 5mA) is reverse-biased at this pin relative to pin 3. |
| 2 | NC | unconnected | Bottom-right lead in the device schematic, drawn with no internal connection to the diode. |
| 3 | K | passive | Cathode of the Zener diode, shown as the single top lead in the device schematic; it goes positive for Zener regulation at 10V nominal. |
