SD103ATW from Changjing, in a SOT-363. 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 | K1 | passive | Cathode of diode 1 (paired with pin 6); each diode is rated 40 V VRRM/VR, 350 mA continuous forward current. |
| 2 | K2 | passive | Cathode of diode 2 (paired with pin 5); each diode is rated 40 V VRRM/VR, 350 mA continuous forward current. |
| 3 | K3 | passive | Cathode of diode 3 (paired with pin 4); each diode is rated 40 V VRRM/VR, 350 mA continuous forward current. |
| 4 | A3 | passive | Anode of diode 3 (paired with pin 3); forward voltage max 0.37 V at IF=20 mA and 0.50 V at IF=100 mA. |
| 5 | A2 | passive | Anode of diode 2 (paired with pin 2); forward voltage max 0.37 V at IF=20 mA and 0.50 V at IF=100 mA. |
| 6 | A1 | passive | Anode of diode 1 (paired with pin 1); forward voltage max 0.37 V at IF=20 mA and 0.50 V at IF=100 mA. |
