TMP300BIDCKR from Texas Instruments, in a SC-70-6. 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	TSET	input	Temperature set pin. External resistor RSET (=10·(50+TC)/3 kΩ, with TC in °C) between TSET and GND programs the trip-point temperature.
2	GND	power_in	Ground reference (0 V) for the device.
3	OUT	output	Active-low open-drain trip output. Asserts low when the measured temperature exceeds the programmed trip point. Requires an external pull-up resistor to V+ (max V+ + 0.5 V, sink 5 mA typical, VOL ≤ 0.3 V).
4	HYSTSET	input	Hysteresis select input. Tie to GND for 5°C hysteresis or to V+ for 10°C hysteresis. Logic thresholds: LOW ≤ 0.4 V, HIGH ≥ VS − 0.4 V.
5	VTEMP	output	Analog temperature output. 10 mV/°C sensitivity, ~750 mV at +25°C. Source impedance ≈ 210 kΩ; drive high-impedance loads only (buffer for ADC input).
6	V+	power_in	Positive supply voltage, 1.8 V to 18 V. Quiescent current 110 µA (max). Bypass to GND with a local ceramic capacitor.
