UDT23A05L02 from UMW, in a SOT-23. 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 with 5V reverse stand-off voltage (VRWM), 0.8pF max junction capacitance to GND and 12V max clamping voltage at IPP=1A. |
| 2 | I/O2 | passive | ESD-protected high-speed data line 2 with 5V reverse stand-off voltage (VRWM), 0.8pF max junction capacitance to GND and 12V max clamping voltage at IPP=1A. |
| 3 | GND | power_in | Common ground return node of the TVS array, to which both I/O clamp diodes connect (capacitance is specified between I/O pins and GND). |
