TMP100NA from Texas Instruments, in a SOT-23-6. 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	Serial clock input for the I2C/SMBus/Two-Wire interface. Open-drain; requires an external pullup resistor to V+. Supports fast mode (400 kHz) and high-speed mode (up to 2 MHz).
2	GND	power_in	Ground reference. Also serves as the primary thermal path since it is directly connected to the metal lead frame.
3	ADD1	input	Address select pin 1. Connect to GND, V+, or leave floating to set one of three logic levels used to encode the I2C slave address. Sampled at power-up and latched.
4	V+	power_in	Positive supply voltage input, 2.7 V to 5.5 V. Absolute maximum 7.5 V.
5	ADD0	input	Address select pin 0. Connect to GND, V+, or leave floating to set one of three logic levels used to encode the I2C slave address. Sampled at power-up and latched.
6	SDA	bidirectional	Serial data line for the I2C/SMBus/Two-Wire interface. Open-drain output; requires an external pullup resistor to V+.
