SZBZX84C13LT3G 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 (SOT-23 CASE 318 Style 8); the Zener is reverse-biased with the cathode positive relative to this pin. |
| 2 | NC | unconnected | No connection (SOT-23 CASE 318 Style 8). |
| 3 | Cathode | passive | Cathode of the Zener diode, indicated by the polarity band (SOT-23 CASE 318 Style 8). |
