TPD3V3F4U6S from TECH PUBLIC, 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 | ESD-protected I/O line with steering diodes to the VCC and GND rails, rated for 3.3V reverse working voltage and 0.8pF max capacitance to GND. |
| 2 | GND | power_in | Ground pin connected to the anode of the internal TVS zener and the lower steering-diode rail, used as the reference for I/O clamping. |
| 3 | I/O2 | passive | ESD-protected I/O line with steering diodes to the VCC and GND rails, rated for 3.3V reverse working voltage and 0.8pF max capacitance to GND. |
| 4 | I/O3 | passive | ESD-protected I/O line with steering diodes to the VCC and GND rails, rated for 3.3V reverse working voltage and 0.8pF max capacitance to GND. |
| 5 | VCC | power_in | Positive rail pin connected to the upper steering-diode rail and TVS zener cathode, with a clamping voltage of 12V typ at Ipp=8A (VCC pin to ground). |
| 6 | I/O4 | passive | ESD-protected I/O line with steering diodes to the VCC and GND rails, rated for 3.3V reverse working voltage and 0.8pF max capacitance to GND. |
