KBAT43W-7-F from KUU, 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 of the diode; the datasheet's absolute maximum ratings give a Repetitive Peak Reverse Voltage (VRRM) of 30 V and a Forward Continuous Current (IFM) of 200 mA. |
| 2 | Anode | passive | Anode terminal of the diode; the datasheet's absolute maximum ratings give a Repetitive Peak Reverse Voltage (VRRM) of 30 V and a Forward Continuous Current (IFM) of 200 mA. |
