KTH2502QB-ST3

CONNTEK · Hall Switches · SOT-23-3L

KTH2502QB-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 VCC power_in Power supply input; the device operates from 2.7 V to 32 V with no external regulator and withstands reverse supply voltage down to -22 V.
2 OUTPUT output Open-drain NMOS output rated for a sink current of up to 30 mA, with output pin voltage limited to 0 V to 32 V and requiring an external pull-up resistor.
3 GND power_in Ground reference pin for the device.
