BZT52C22 from MDD Microdiode Semiconductor, in a SOD-123. 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 | K | passive | Cathode, the terminal marked by the cathode bar on the SOD-123 body; it goes positive relative to the anode in zener breakdown (BZT52C22: VZ 20.9-23.1 V at IZT 5 mA). |
| 2 | A | passive | Anode, the terminal opposite the cathode bar on the SOD-123 body; the diode symbol shows forward conduction from anode to cathode (VF 0.9 V at IF 10 mA). |
