QX7135E35 from QX Micro Devices, in a SOT-89. 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 | LED | passive | LED output pin that connects to the LED cathode and sinks the constant LED current (100mA to 380mA range, 500mA absolute maximum, 7V maximum voltage). |
| 2 | GND | power_in | Power ground. |
| 3 | VDD | power_in | Power supply input with 2.7V to 5.5V operating range, 7V absolute maximum, and a recommended ~4.7uF filter capacitor placed close to the pin. |
