NUP2105LT1G-MS from MSKSEMI, 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 to the steering/TVS diode structure, with reverse working voltage VRWM of 24 V, breakdown voltage VBR of 27 V at 1 mA, and ±30 kV IEC 61000-4-2 ESD rating. |
| 2 | I/O2 | passive | Protected line 2 connected to the steering/TVS diode structure, with reverse working voltage VRWM of 24 V, breakdown voltage VBR of 27 V at 1 mA, and ±30 kV IEC 61000-4-2 ESD rating. |
| 3 | COMMON | passive | Common node shared by both protection diode pairs, shown as pin 3 on the package drawing; the datasheet does not label it as ground. |
