LL103B-GS08 from Vishay Intertech, 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, marked by the black cathode band on the MiniMELF SOD-80 case; LL103B withstands VR = 30 V reverse voltage and 200 mA continuous forward current. |
| 2 | A | passive | Anode of the single Schottky diode, opposite the cathode band; LL103B has forward voltage of 370 mV max at IF = 20 mA and 600 mV max at IF = 200 mA. |
