BZX84C4V3W from Yangzhou Yangjie Elec Tech, in a SOT-323(SC-70). 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 page 1 internal diagram wired from bottom-left terminal 1 to the diode anode. |
| 2 | NC | unconnected | Not connected internally; the page 1 diagram shows no connection to the diode at this terminal. |
| 3 | K | passive | Cathode of the zener diode (bar side), connected to top terminal 3; BZX84C4V3W has VZ of 4.0 V min, 4.3 V typ, 4.6 V max at IZT=5 mA. |
