ESD12VS2UT-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 | 1 | passive | Protected line 1 connection of the two-line TVS array, shown in the package diagram as the terminal of one diode, with a 12V maximum working voltage (VRWM) and 13.3V minimum breakdown at 1mA. |
| 2 | 2 | passive | Protected line 2 connection of the two-line TVS array, shown in the package diagram as the terminal of the second diode, with a 12V maximum working voltage (VRWM) and 13.3V minimum breakdown at 1mA. |
| 3 | 3 | passive | Common terminal joining both diodes in the package diagram, shared by lines 1 and 2; the datasheet does not label it as ground or give its function by name. |
