BAS20DWQ-13 from Diodes Incorporated, in a SOT-363. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | A1 | passive | Anode of diode 1. Forward voltage 1.0V max at IF = 100mA. Continuous forward current 200mA per diode; 400mA total when both diodes are paralleled. |
| 2 | A2 | passive | Anode of diode 2. Forward voltage 1.0V max at IF = 100mA. Continuous forward current 200mA per diode. |
| 3 | K2 | passive | Cathode of diode 2. Reverse breakdown 200V min, reverse current 100nA max at TJ = +25°C. |
| 4 | A3 | passive | Third anode terminal shown in the SOT-363 internal schematic (device contains two electrically independent diodes routed to distinct anodes and cathodes on all six leads). |
| 5 | K3 | passive | Cathode terminal per internal schematic. Reverse breakdown 200V min. |
| 6 | K1 | passive | Cathode of diode 1. Reverse breakdown 200V min, reverse current 100nA max at TJ = +25°C. |
