PESD3V3U1UT-TP from TECH PUBLIC, in a SOT-23. 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 | IO1 | passive | ESD-protected I/O line 1 (TVS diode to pin 3), 3.3 V reverse working voltage, 0.7 pF max to pin 3 and 0.35 pF typical to pin 2 at VR=0, f=1MHz. |
| 2 | IO2 | passive | ESD-protected I/O line 2 (TVS diode to pin 3), 3.3 V reverse working voltage, 0.7 pF max to pin 3 and 0.35 pF typical to pin 1 at VR=0, f=1MHz. |
| 3 | GND | power_in | Common cathode/return node of the two TVS diodes, connected to ground; the diagram shows pin 3 as the shared connection to both diodes. |
