TPESD0304C5

TECH PUBLIC · ESD And Surge Protection (TVS/ESD) · SOT-353

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.
