CPDH3V3UP-TP

TECH PUBLIC · ESD Protection Devices · SOD-523

CPDH3V3UP-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 uni-directional TVS diode, shown on the bar side (left) of the top-view symbol; connect to the protected line, working reverse voltage 3.3V max, breakdown 5V min at 1mA.
2 A passive Anode of the uni-directional TVS diode, shown on the triangle side (right) of the top-view symbol; typically connected to ground.
