BCR402UW6Q-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, connected to the internal emitter-follower bias resistor network. |
| 2 | OUT | passive | Regulated output current to the LED string, rated 100mA max and 40V max output voltage; also the heat-sinking lead. |
| 3 | OUT | passive | Regulated output current to the LED string, rated 100mA max and 40V max output voltage; also the heat-sinking lead. |
| 4 | VS | power_in | Supply voltage input, rated 40V maximum relative to GND. |
| 5 | OUT | passive | Regulated output current to the LED string, rated 100mA max and 40V max output voltage; also the heat-sinking lead. |
| 6 | Rext | passive | Optional external resistor pin that, in parallel with the 44 ohm internal resistor, raises output current above the preset 20mA up to 100mA. |
