BZT52C18W 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 (pin 1 in the SOD-123 top view and symbol); the datasheet gives no per-pin electrical limits. |
| 2 | Anode | passive | Anode terminal of the Zener diode (pin 2 in the SOD-123 top view and symbol); the datasheet gives no per-pin electrical limits. |
