AZ23C16 from Changjing, 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 | K1 | passive | Cathode of zener diode 1 (AZ23C16: Vz 15.3-17.1V at IZT=5.0mA), in a dual common-anode configuration with 300mW package dissipation. |
| 2 | K2 | passive | Cathode of zener diode 2 (AZ23C16: Vz 15.3-17.1V at IZT=5.0mA), with Vz matched to diode 1 within 5%. |
| 3 | A | passive | Common anode of both zener diodes, shared by pins 1 and 2. |
