KTH1631FU-ST3

CONNTEK · Hall Switches · SOT-23-3L

KTH1631FU-ST3 from CONNTEK, in a SOT-23-3L. 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 Power supply input; operating supply range is 1.6 V to 5.5 V per the recommended operating range, with an absolute maximum supply voltage of 6 V.
2 OUTPUT output Magnetic switch output that turns on (Low) when the magnetic flux density exceeds BOP and turns off (High) when it falls below BRP, with an absolute maximum output current of 5 mA.
3 GND power_in Ground pin.
