Integrated UVA and UVB Light Sensor with Filtron Technology

Vishay Intertechnology introduced a new integrated ultraviolet (UV) light sensor for the detection of UVA and UVB light intensity. Featuring Filtron technology for high UV sensitivity and linearity, the Vishay Semiconductors VEML6075 incorporates an IC with five sensitive areas and signal processing in a compact 2.0 mm by 1.25 mm by 1.0 mm surface-mount package while offering an I²C bus interface for simple operation. The device saves space and increases design flexibility by incorporating the circuitry needed for consumer, medical, and industrial applications in one compact unit.

The light sensor released today offers individual UVA and UVB channels with 16-bit resolution and excellent sensitivity of 365 nm and 330 nm, respectively. Designed to convert solar UV light intensity to digital data, the VEML6075 provides a measurement of signal strength and allows for true UVI calculation in smartphones, smart watches, sport bands, notebook computers, and weather stations. The UVI value indicates how much UV radiation will reach human skin when outside, allowing precautions to be taken to avoid sunburns in the short term and skin cancer in the long term.

The VEML6075 delivers excellent performance under long-term solar UV exposure and offers high temperature compensation stability from -40 °C to +85 °C. The device features a shutdown mode that reduces power consumption to 800 nA and an operating voltage range of 1.7 V to 3.6 V — ideal for portable electronics and wearable devices. Offered in a lead (Pb)-free, 4-pin OPLGA package, the VEML6075 is RoHS-compliant, halogen-free, and Vishay Green.

Samples and production quantities of the new UVA and UVB light sensor are available now, with lead times of 12 weeks for large orders.
