LUDZS15BT1G 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 | CATHODE | passive | Cathode, indicated by the polarity band on the package; the Zener regulation voltage VZ is specified with the device reverse-biased from cathode to anode. |
| 2 | ANODE | passive | Anode of the Zener diode; forward voltage is 0.9 V max at IF = 10 mA for all types in this series. |
