TPESD0304C5 from TECH PUBLIC, in a SOT-353. 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 1 with a steering diode pair to the common node and GND; the datasheet gives 0.45 pF typ (0.7 pF max) I/O-to-GND capacitance and 3.3 V max reverse working voltage. |
| 2 | GND | power_in | Common ground connection of the 4-line ESD array, to which all I/O lines are clamped. |
| 3 | I/O2 | passive | ESD-protected I/O line 2 with a steering diode pair to the common node and GND; the datasheet gives 0.45 pF typ (0.7 pF max) I/O-to-GND capacitance and 3.3 V max reverse working voltage. |
| 4 | I/O3 | passive | ESD-protected I/O line 3 with a steering diode pair to the common node and GND; the datasheet gives 0.45 pF typ (0.7 pF max) I/O-to-GND capacitance and 3.3 V max reverse working voltage. |
| 5 | I/O4 | passive | ESD-protected I/O line 4 with a steering diode pair to the common node and GND; the datasheet gives 0.45 pF typ (0.7 pF max) I/O-to-GND capacitance and 3.3 V max reverse working voltage. |
