BZX84C4V7Q 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 (per the page 1 internal diagram); 4.7V nominal Zener voltage (4.4V min to 5.0V max at IZT=5mA) for the BZX84C4V7Q. |
| 2 | NC | unconnected | Pin 2 has no internal connection in the page 1 diagram (not wired to the diode). |
| 3 | K | passive | Cathode of the Zener diode (per the page 1 internal diagram); maximum power dissipation 350mW and maximum forward voltage 0.9V at IF=10mA. |
