DS18B20T from XBLW, 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; under parasite-power mode VDD must be floated, not tied to ground. |
| 2 | DQ | bidirectional | Data input/output pin for the 1-Wire bus, pulled up to Vpu (2.6V~5.5V) through a 3kΩ resistor in the block diagram. |
| 3 | VDD | power_in | Power supply pin, 2.6V to 5.5V operating range (absolute maximum 6V); must be left floating, not grounded, in parasite-power mode. |
