LMSD103AT1G 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, identified by the cathode band on the package; the datasheet gives no pin-specific limits, so the device maximum ratings (for example 40 V VRRM and 350 mA forward current for the LMSD103AT1G) apply. |
| 2 | ANODE | passive | Anode terminal; the datasheet gives no pin-specific limits, so the device maximum ratings and forward characteristics at 25 °C apply. |
