DS18B20-MS from MSKSEMI, 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 pin for the DS18B20 (TO-92 pin 1, 1-Wire bus and supply return). |
| 2 | DQ | bidirectional | Data input/output pin of the 1-Wire bus; it needs an external pull-up (about 4.7 kΩ to 5 kΩ shown in the datasheet) and also powers the chip in parasitic mode, where a strong pull-up is required during temperature conversion and EEPROM copy. |
| 3 | VDD | power_in | Supply pin, 2.5 V to 5.5 V in local-supply mode; it must be connected to GND when the device runs in parasitic power mode. |
