KTM1301SE-TO3

CONNTEK · Linear Hall Sensors · TO-92S

KTM1301SE-TO3 from CONNTEK, in a TO-92S. 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	OUTPUT	output	CMOS push-pull output that goes low when the field exceeds BOP and high when below BRP, with a maximum output drive current of 5 mA.
2	GND	power_in	Ground pin.
3	VDD	power_in	Power supply input for 1.8 V to 5.5 V operation (6 V absolute maximum), with a 100 nF capacitor placed close to the pin.
