PRTR5V0U2AX from Nexperia, in a SOT-143. 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 | GND | power_in | Ground reference pin; the input/output-to-ground and supply-to-ground capacitances in the datasheet are measured to this pin. |
| 2 | I/O 1 | bidirectional | Input/output 1 is one of the two high-speed data or signal lines protected by the device, with 1.8 pF typical input/output-to-ground capacitance (f = 1 MHz, V(I/O-GND) = 0 V, Tamb = 25 °C) and ESD protection up to 12 kV per IEC 61000-4-2 level 4. |
| 3 | I/O 2 | bidirectional | Input/output 2 is the second high-speed data or signal line protected by the device, with 1.8 pF typical input/output-to-ground capacitance (f = 1 MHz, V(I/O-GND) = 0 V, Tamb = 25 °C) and ESD protection up to 12 kV per IEC 61000-4-2 level 4. |
| 4 | VCC | power_in | Supply voltage pin tied to the integrated additional ESD diode between ground and VCC, which prevents charging of the supply; supply-to-ground capacitance is 16 pF typical at VCC = 0 V. |
