BZX84B16 from Yangzhou Yangjie Elec Tech, in a SOT-23(TO-236). 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 (BZX84B16: Vz 16 V typ, 15.68-16.3 V at Izt=5 mA), connected to the diode's left side in the package diagram. |
| 2 | NC | unconnected | Not connected internally; the package diagram shows no connection to the diode. |
| 3 | K | passive | Cathode of the Zener diode, which is at the positive voltage in reverse breakdown regulation; power dissipation is limited to 350 mW. |
