BZX84C75 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; the SOT-23 diagram on page 1 connects pin 1 to the diode's triangle side, with forward voltage max 0.9 V at IF=10mA. |
| 2 | NC | unconnected | Pin 2 is shown on the SOT-23 diagram with no internal connection to the diode. |
| 3 | K | passive | Cathode of the zener diode; pin 3 connects to the bar side, with nominal Zener voltage 75V (70V min to 79V max) at IZT=2mA and power dissipation 350 mW. |
