BZT52-B18_R1_00001 from PANJIT International, 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, identified by the package polarity diagram (pin 1 = Cathode, pin 2 = Anode). |
| 2 | Anode | passive | Anode terminal of the Zener diode, identified by the package polarity diagram (pin 2 = Anode, pin 1 = Cathode). |
