UBT26A05L03 from Brightking, in a SOT-23-6L. 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 | I/O1 | bidirectional | ESD-protected data line with 5 V working voltage (reverse stand-off VRWM 5.25 V max), 1 µA max reverse leakage at 5.25 V, and IEC61000-4-2 protection rated ±8 kV contact / ±15 kV air. |
| 2 | GND | power_in | Ground reference for the protection clamp; off-state junction capacitance of 3.5 pF max is specified between the I/O pins and GND. |
| 3 | I/O2 | bidirectional | ESD-protected data line with 5 V working voltage (reverse stand-off VRWM 5.25 V max), 1 µA max reverse leakage at 5.25 V, and IEC61000-4-2 protection rated ±8 kV contact / ±15 kV air. |
| 4 | I/O2 | bidirectional | ESD-protected data line with 5 V working voltage (reverse stand-off VRWM 5.25 V max), 1 µA max reverse leakage at 5.25 V, and IEC61000-4-2 protection rated ±8 kV contact / ±15 kV air. |
| 5 | VBUS | power_in | Pin labelled VBUS in the pin configuration; the datasheet gives no separate electrical limit or function for it beyond the USB application diagram on page 3. |
| 6 | I/O1 | bidirectional | ESD-protected data line with 5 V working voltage (reverse stand-off VRWM 5.25 V max), 1 µA max reverse leakage at 5.25 V, and IEC61000-4-2 protection rated ±8 kV contact / ±15 kV air. |
