PESD3V3L4UG

TECH PUBLIC · ESD Protection Devices · SOT-353

PESD3V3L4UG 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 line 1 with a steered diode path to the common pin 2, rated for ±20 kV air and ±15 kV contact discharge per IEC 61000-4-2 and 0.45 pF typical (0.7 pF max) capacitance to GND.
2 GND power_in Common ground connection shared by all four protection diodes, with a 3.3 V maximum reverse working voltage on the I/O lines relative to it.
3 I/O2 passive ESD-protected line 2 with a steered diode path to the common pin 2, rated for ±20 kV air and ±15 kV contact discharge per IEC 61000-4-2 and 0.45 pF typical (0.7 pF max) capacitance to GND.
4 I/O3 passive ESD-protected line 3 with a steered diode path to the common pin 2, rated for ±20 kV air and ±15 kV contact discharge per IEC 61000-4-2 and 0.45 pF typical (0.7 pF max) capacitance to GND.
5 I/O4 passive ESD-protected line 4 with a steered diode path to the common pin 2, rated for ±20 kV air and ±15 kV contact discharge per IEC 61000-4-2 and 0.45 pF typical (0.7 pF max) capacitance to GND.
