SC2442SO-N-TR

Semiment · Hall Switches · SOT-23

SC2442SO-N-TR 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 VDD power_in Supply voltage input, specified from 2.5V to 24V, with reverse polarity protection to -28V.
2 OUT output Open-drain output that requires an external pull-up resistor; it can sink up to 20mA.
3 GND power_in Ground connection.
