ESD24VC2 from UMW, 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 cathode of the first uni-directional TVS diode, with 24V reverse stand-off voltage (VRWM). |
| 2 | I/O2 | passive | Protected line 2 connected to the cathode of the second uni-directional TVS diode, with 24V reverse stand-off voltage (VRWM). |
| 3 | GND | power_in | Common anode of both TVS diodes, shown as the shared pin 3 in the schematic, to be tied to ground. |
