PESD3V3L1UA-P from TECH PUBLIC, in a SOD-323. 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 | IO | passive | Protected data or power line connection (cathode side of the unidirectional TVS), 3.3V max reverse working voltage, 4.8V min breakdown at 1mA, 15V max clamping at 20A (8/20µs). |
| 2 | GND | power_in | Ground reference (anode side of the TVS diode) for the protected line, shown on the right of the terminal diagram. |
