TPNUP1105LT1G from TECH PUBLIC, in a SOT-23-3. 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 | passive | Line pin of the 2-line uni-directional TVS, with 20 pF junction capacitance to Pin 2 and 70 pF to Pin 3 at VR=0 V, f=1 MHz, and a 24 V reverse working voltage. |
| 2 | Pin 2 | passive | Line pin of the 2-line uni-directional TVS, with 20 pF junction capacitance to Pin 1 and 70 pF to Pin 3 at VR=0 V, f=1 MHz, and a 24 V reverse working voltage. |
| 3 | Pin 3 | passive | Common pin referenced by the 70 pF junction capacitance measurements to Pin 1 and Pin 2 at VR=0 V, f=1 MHz; the extracted text does not state its net name (e.g. GND). |
