TMP235A2DCKR from Texas Instruments, in a SC-70-5. 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 internal connection. This pin may be left floating or connected to GND.
2	GND	power_in	Power supply ground reference.
3	VOUT	output	Analog output voltage proportional to temperature. Slope 10 mV/°C, offset 500 mV at 0°C (TMP235). Drives up to 500 µA and 1000 pF capacitive load; output impedance ~20 Ω at 100 Hz.
4	VDD	power_in	Positive supply input, 2.3 V to 5.5 V (TMP235). Typical operating current 9 µA at 25°C. Recommend a bypass capacitor to GND per power-supply recommendations.
5	NC	unconnected	No internal connection. This pin may be left floating or connected to GND.
