LUDZS3.0BT1G from LRC, 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 | K | passive | Cathode of the Zener diode, on the end of the package with the marking band; Zener voltage VZ is 3.01 to 3.22 V at IZT=5 mA. |
| 2 | A | passive | Anode of the Zener diode; the device dissipates at most 200 mW (PD) and operates from -55 to +150 °C. |
