TMP6131LPGM from Texas Instruments, in a TO-92-2. 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	-	passive	Negative terminal of the thermistor. Must be held at a lower potential than pin 2 (+) to maintain correct forward bias for normal operation. Absolute maximum voltage across the device is 6 V; recommended VSns is 0 to 5.5 V.
2	+	passive	Positive terminal of the thermistor. Must be held at a higher potential than pin 1 (-) to maintain forward bias. Typical sense current ISns is up to 400 µA (absolute max 450 µA).
