ESD24VU1UT-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 of the two lines, with a diode to the common pin 3; 24V max working voltage (VRWM), 26.7V min breakdown at 1mA, 1.5pF max capacitance. |
| 2 | I/O2 | passive | Protected line 2 of the two lines, with a diode to the common pin 3; 24V max working voltage (VRWM), 26.7V min breakdown at 1mA, 1.5pF max capacitance. |
| 3 | COMMON | passive | Common node joining the two protection diodes of pins 1 and 2 in the package diagram; the datasheet does not name it as ground. |
