MY18B20LD10 from Mysentech, in a TO-92L. 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	GND	power_in	Ground reference for the device. Connect to system ground.
2	DQ	bidirectional	1-Wire single-bus digital data I/O. Open-drain / three-state, requires an external pull-up resistor (typ. 10 kΩ, or 1 kΩ for long-cable / multi-drop configurations). Carries all command, ROM ID and temperature traffic; can also parasite-power the device on short lines.
3	VDD	power_in	Supply voltage input, 1.8 V to 5.5 V (recommend ≥3.3 V for long-cable or multi-drop operation). Typical standby current 0.2 µA @5 V; average 5 µA @1 Hz sampling.
