SC25891SE-A
Semiment · Hall Switches · SOT-23
SC25891SE-A from Semiment, 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 | VCC | power_in | Power supply input, specified from 3.3 V to 24 V (operating voltage), with absolute maximum 28 V and reverse supply voltage -18 V. |
| 2 | NC | unconnected | Not internally connected; the datasheet recommends connecting this pin to GND. |
| 3 | GND | power_in | Ground reference terminal for the device; supply and output voltages are referenced to this pin. |
