NUP2105LT1G-N from BORN, 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/O1 | passive | Protected line 1 connected through a bidirectional avalanche TVS diode to common pin 3, with 24.0 V reverse stand-off and 26.7-34.0 V breakdown at 1 mA. |
| 2 | I/O2 | passive | Protected line 2 connected through a bidirectional avalanche TVS diode to common pin 3, with 24.0 V reverse stand-off and 12-15 pF junction capacitance at 0 V, 1 MHz. |
| 3 | COMMON | passive | Common node shared by both bidirectional TVS diodes, typically connected to ground or the reference rail of the protected circuit. |
