DS18B20Z

UMW · Temperature Sensors · SOIC-8

DS18B20Z from UMW, in a SOIC-8. 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 N.C. unconnected No Connection pin; the datasheet lists it as not connected.
2 N.C. unconnected No Connection pin; the datasheet lists it as not connected.
3 VDD power_in Optional supply pin; VDD must be grounded for operation in parasite power mode.
4 DQ bidirectional Open-drain 1-Wire data input/output that also provides power to the device when used in parasite power mode.
5 GND power_in Ground reference for the device.
6 N.C. unconnected No Connection pin; the datasheet lists it as not connected.
7 N.C. unconnected No Connection pin; the datasheet lists it as not connected.
8 N.C. unconnected No Connection pin; the datasheet lists it as not connected.

CAD (KiCad official)

  • Symbol: DS18B20Z
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: ds18b20z-etched.step / ds18b20z-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ds18b20z.step / ds18b20z.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: UMW datasheet (31 pp, sha256 a032e7e0ab6e3df7, retrieved 2026-11-04, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-haiku-5-5 (text), consensus claude-sonnet-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
