PESD3V3S1UB-TP

TECH PUBLIC · ESD Protection Devices · SOD-523

PESD3V3S1UB-TP from TECH PUBLIC, in a SOD-523. 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 K passive Cathode of the 1-line uni-directional TVS diode, connected to the protected power or I/O line (VRWM 3.3V max, VBR 4.5V min at 1mA).
2 A passive Anode of the uni-directional TVS diode, connected to ground (reference) for ESD protection of ±30kV air/contact per IEC 61000-4-2.
