BZX84C3V3W
Yangzhou Yangjie Elec Tech · Zener Diodes · SOT-323(SC-70)
BZX84C3V3W 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 (3.3V nominal, 3.1V to 3.5V at IZT=5mA), connected to the triangle side of the symbol. |
| 2 | NC | unconnected | No internal connection; the package symbol shows this lead with no connection to the diode. |
| 3 | K | passive | Cathode of the Zener diode, connected to the bar side of the symbol; 200mW power dissipation rating. |
