The STS4xA is Sensirion’s highly reliable, automotive-grade digital temperature sensor series. The series currently consists of two versions: STS41A-AD1B and STS41A-AW1B, with the latter offering optional wettable flanks packaging to support automated optical inspection (AOI). Moreover, the integrated on-chip heater enables advanced on-board diagnosis (OBD).

The sensor platform is based on Sensirion’s CMOSens® Technology and extensive experience in temperature sensing, and it therefore benefits from the company’s well-established engineering expertise. The cost-efficient STS4xA features an I²C interface and provides a wide supply voltage range of 2.3–5.5 V. Thanks to its small size and the four-pin dual-flat no-leads (DFN) package, the STS4xA can easily be integrated into a variety of automotive applications. Moreover, it meets relevant industry requirements, such as 85°C/85%RH accelerated life tests.
