NS18B20-QTOS from NOVOSENSE, in a TO-92. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Ground reference pin for the device. |
| 2 | DQ | bidirectional | Open-drain 1-Wire data input/output that requires a weak pull-up resistor on the bus and also supplies power to the device in parasite power mode. |
| 3 | VDD | power_in | Optional supply pin for 2.7 V to 5.5 V external power, which must be grounded for operation in parasite power mode. |
