S-LBZT52C27T1G from LRC, 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, marked by the polarity band on the SOD-123 package. The datasheet gives the total device power dissipation as 500 mW. |
| 2 | ANODE | passive | Anode terminal of the zener diode, opposite the cathode polarity band on the SOD-123 package. |
