SZBZX84C8V2ET3G from onsemi, 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 | ANODE | passive | Anode of the Zener diode; the cathode is identified by the polarity band on the package. |
| 2 | NO CONNECTION | unconnected | No connection on this pin (datasheet pinout: 2-No Connection). |
| 3 | CATHODE | passive | Cathode of the Zener diode, marked by the polarity band on the package. |
