UBT32A05L02 from Brightking Elec (TAIWAN), in a SOT-323. 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 | passive | ESD-protected high-speed data line 1, steered by a TVS diode to common pin 3 with 0.8pF typical capacitance to GND, 5V working voltage and 1µA max leakage at VR=5V. |
| 2 | I/O2 | passive | ESD-protected high-speed data line 2, steered by a TVS diode to common pin 3 with 0.8pF typical capacitance to GND, 5V working voltage and 1µA max leakage at VR=5V. |
| 3 | GND | power_in | Common ground connection shared by both TVS diodes, referenced for the ±8kV contact and ±15kV air ESD ratings. |
