BZT52C22-7-F from Diodes Incorporated, 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 band; the Zener voltage for BZT52C22 is 22V nominal (20.8V to 23.3V) at IZT = 5mA. |
| 2 | A | passive | Anode, the terminal opposite the cathode band; the device dissipates up to 500mW at TL = +75°C. |
