TPNUP2105LT1G 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 | I/O 1 | passive | Protected line 1 of the bi-directional TVS pair, connected through the back-to-back diodes to pin 3, with 25pF typical junction capacitance between pin 1 and pin 2. |
| 2 | I/O 2 | passive | Protected line 2 of the bi-directional TVS pair, connected through the back-to-back diodes to pin 3, with reverse working voltage of 24V max. |
| 3 | Common | passive | Common node joining both TVS diode branches (pin 1 and pin 2 each connect to it), with ESD rating of ±30kV air and contact per IEC 61000-4-2. |
