BZX84C36 from FOSAN, 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 single Zener diode, shown connected through the diode to pin 3; Zener voltage VZ is 34.0 to 38.0 V (36 V nominal) at IZ=2 mA. |
| 2 | NC | unconnected | Not connected internally; the internal configuration drawing shows pin 2 with no connection to the diode. |
| 3 | K | passive | Cathode of the single Zener diode, connected through the diode to pin 1; power dissipation is 300 mW max at Ta=25℃. |
