BZV55B11 from LGE, in a SOD-80. 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 | K | passive | Cathode (negative polarity) terminal, marked by the blue color band; BZV55B11 has VZ 10.78 to 11.22 V at IZT = 5 mA. |
| 2 | A | passive | Anode terminal at the end opposite the blue color band; Ptot is 500 mW and forward voltage is 1.0 V max at IF = 100 mA. |
