BZT52-C18S_R1_10001 from PANJIT International, in a SOD-323. 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, marked by the color band on the SOD-323 body; the zener breakdown voltage (VZ, 17.10 to 18.90 V for the BZT52-C18S) is referenced to this terminal. |
| 2 | Anode | passive | Anode, the terminal opposite the color band cathode; it is the non-band end of the SOD-323 package. |
