An ambient temperature sensor is provided that may be coupled to a PCB. The ambient temperature sensor includes a package including a first cap and an insulating structure. The insulating structure is formed of thermally insulating material, and the first cap and the insulating structure delimit a first cavity. A semiconductor device is included and generates an electrical signal indicative of a temperature. The semiconductor device is fixed on top of the insulating structure and arranged within the first cavity. The package may be coupled to the PCB so that the insulating structure is interposed between the semiconductor device and the PCB. The insulating structure delimits a second cavity, which extends below the semiconductor device and is open laterally.
