BZX84C16A from Shandong Jingdao Microelectronics, 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 | Zener diode anode (Suffix A single-diode version, connected to pin 3 through the diode); forward voltage 0.9 V at IF = 10 mA. |
| 2 | NC | unconnected | Not connected internally in the Suffix A single-diode version; no internal connection is shown in the package diagram. |
| 3 | K | passive | Zener diode cathode (BZX84C16A: 16 V nominal zener voltage, 15.68 to 16.32 V range for the ±2% grade); max power dissipation 350 mW. |
