TMP1075NDRLR from Texas Instruments, in a SOT-563. 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	SCL	input	I2C/SMBus serial clock input. Requires external pullup resistor (typ. 5 kΩ) to V+.
2	GND	power_in	Ground reference for the device.
3	ALERT	output	Overtemperature alert. Open-drain output requiring an external pullup resistor. Asserted when the temperature exceeds the programmed high limit (or per configured comparator/interrupt mode).
4	A0	input	I2C slave address select input A0. Connect to GND, V+, SDA, or SCL to select one of the available I2C bus addresses (up to 4 addresses on TMP1075N DRL).
5	V+	power_in	Positive supply voltage input. 1.62 V to 3.6 V for TMP1075N. A 0.01 µF bypass capacitor to GND is recommended close to the pin.
6	SDA	bidirectional	I2C/SMBus serial data line. Open-drain, bidirectional; requires external pullup resistor (typ. 5 kΩ) to V+.
