TPESD3V3U1UB 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 | Pin 1 (diode terminal) | passive | One terminal of the uni-directional 1-line TVS diode; the datasheet references Pin 1 to Pin 2 for junction capacitance (0.5 pF typical, 0.9 pF maximum at VR = 0 V, f = 1 MHz). |
| 2 | Pin 2 (diode terminal) | passive | Other terminal of the uni-directional 1-line TVS diode; the datasheet references Pin 1 to Pin 2 for junction capacitance (0.5 pF typical, 0.9 pF maximum at VR = 0 V, f = 1 MHz), with a 3.3 V reverse working voltage and 14 V clamping voltage at Ipp = 4 A (8/20 µs). |
