BCR405UW6-7 from Diodes Incorporated, in a SOT-26. 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 | GND | power_in | Power ground; all voltages are specified relative to GND. |
| 2 | OUT | output | Regulated LED output current, 50mA preset and up to 100mA maximum, with output voltage up to 40V. |
| 3 | OUT | output | Regulated LED output current, 50mA preset and up to 100mA maximum, with output voltage up to 40V. |
| 4 | VS | power_in | Supply voltage input, rated up to 40V relative to GND. |
| 5 | OUT | output | Regulated LED output current, 50mA preset and up to 100mA maximum, with output voltage up to 40V. |
| 6 | Rext | passive | Optional external resistor connection that adjusts the output current from the 50mA preset up to 100mA. |
