Vishay Intertechnology releases its new ultraviolet (UV) light sensor featuring the Filtron UV technology for high UV sensitivity and linearity. The Vishay Semiconductors VEML6070 is designed for converting solar UV light intensity to digital data for consumer, medical and industrial applications, incorporates a photo-pin-diode and signal processing IC in a compact 2.35mm x 1.8mm x 1mm surface-mount package. It also offers an I2C bus interface for simple operation.

The device released is optimised for UV detection in smartphones, health monitoring and fitness products, flame detectors, and weather stations. The sensor saves space by incorporating the circuitry needed for these applications in one compact unit. A robust refresh rate setting lowers costs and simplifies designs by eliminating the need for an external RC low pass filter. The VEML6070 offers high dynamic detection resolution and excellent performance under long-term solar UV exposure, while an active acknowledge (ACK) feature with threshold window settings sends out UVI alert messages under strong solar conditions.


The VEML6070's built-in photo-pin-diode offers spectral sensitivity from 280nm to 400nm, with a peak sensitivity wavelength of 355nm. The sensor provides fluorescent light flicker immunity, a software shutdown mode to reduce power consumption to less than 1?A, and excellent temperature compensation stability from -40C to 85C. The device features an operating voltage and I2C bus voltage range of 2.7V to 5.5V and is offered in a lead (Pb)-free OPLGA package. The VEML6070 is RoHS-compliant, halogen-free, and Vishay GREEN.

Samples and production quantities of the new UV light sensor are available now, with lead times of six to eight weeks for large orders.
