BZT52C22W from CBI, 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 | Cathode | passive | Cathode terminal of the Zener diode, shown as pin 1 in the SOD-123 top view; the datasheet gives total device power dissipation of max. 500 mW and junction temperature of 150 °C but no pin-specific limit. |
| 2 | Anode | passive | Anode terminal of the Zener diode, shown as pin 2 in the SOD-123 top view; the datasheet gives a forward voltage of 0.9 V max at IF = 10 mA but no pin-specific limit. |
