KTH1601TL-SF5 from CONNTEK, in a SOT-553-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	NC	unconnected	No connection. Leave floating or tie to GND per PCB layout preference.
2	GND	power_in	Ground reference (0 V). Common return for the supply and output driver.
3	NC	unconnected	No connection. Leave floating or tie to GND per PCB layout preference.
4	VDD	power_in	Power supply input, 1.6 V to 5.5 V (6 V absolute max). Recommended 1 µF decoupling capacitor placed close to this pin for noise immunity.
5	OUTPUT	output	Push-pull digital Hall switch output. Drives VOL ≈ 0.05 V (on-state) or VOH ≈ VDD-0.05 V (off-state) at IOUT = 1 mA; maximum output current 5 mA. State toggles based on magnetic flux density relative to BOP/BRP thresholds.
