UAT36A03L05 from YAGEO, in a SOT-363. 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 | Protected high-speed data line input with a low-capacitance steering diode pair (0.5 pF max between I/O and GND at 0 V, 1 MHz) and ±8 kV contact / ±15 kV air ESD protection. |
| 2 | GND | power_in | Ground connection at the anode of the TVS diode, the return for the steering diodes. |
| 3 | I/O2 | passive | Protected high-speed data line input with a low-capacitance steering diode pair (0.5 pF max between I/O and GND at 0 V, 1 MHz) and ±8 kV contact / ±15 kV air ESD protection. |
| 4 | I/O3 | passive | Protected high-speed data line input with a low-capacitance steering diode pair (0.5 pF max between I/O and GND at 0 V, 1 MHz) and ±8 kV contact / ±15 kV air ESD protection. |
| 5 | VP | power_in | Protected power line connection at the TVS diode cathode, with 3.3 V reverse stand-off voltage (VRWM). |
| 6 | I/O4 | passive | Protected high-speed data line input with a low-capacitance steering diode pair (0.5 pF max between I/O and GND at 0 V, 1 MHz) and ±8 kV contact / ±15 kV air ESD protection. |
