PESD5V0V4UW-TP from TECH PUBLIC, in a SOT-553. 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 | IO1 | passive | ESD-protected I/O line 1 (steering diodes to GND), rated 5V max reverse working voltage (VRWM) to ground. |
| 2 | GND | power_in | Common ground reference for the TVS array; all I/O pins are rated 5V VRWM to this pin. |
| 3 | IO2 | passive | ESD-protected I/O line 2 (steering diodes to GND), rated 5V max reverse working voltage (VRWM) to ground. |
| 4 | IO3 | passive | ESD-protected I/O line 3 (steering diodes to GND), rated 5V max reverse working voltage (VRWM) to ground. |
| 5 | IO4 | passive | ESD-protected I/O line 4 (steering diodes to GND), rated 5V max reverse working voltage (VRWM) to ground. |
