MSNUP2105LT1G 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: the TVS diode steers surges to common pin 3, with VRWM 24 V, VBR 27 V min at 1 mA and 25 pF typical capacitance. |
| 2 | I/O2 | passive | Protected line 2: the TVS diode steers surges to common pin 3, with VRWM 24 V, VBR 27 V min at 1 mA and 25 pF typical capacitance. |
| 3 | COMMON | passive | Common pin shared by both TVS diodes, normally tied to ground or the reference rail; the datasheet drawing does not name it. |
