May 14, 2025 /SemiMedia/ — Vishay Intertechnology, Inc. recently introduced the industry’s first AEC-Q100 qualified rectangular ambient light sensor. The Vishay Semiconductors VEML4031X00 features an ALS and highly sensitive IR photodiode in an opaque 4.38 mm by 1.45 mm surface-mount package with a low 0.6 mm profile. Offering half the width of previous-generation solutions, the device allows for easier integration into space-constrained designs, such as bezel-less center control displays.

Highly accurate measurements are supported due to the spectral sensitivity of the Automotive Grade sensor released today, which matches that of the human eye, while its IR channel allows for light source differentiation. With an ambient light range from 0 lx to 172 000 lx, the VEML4031X00 will not saturate in daylight, while its high sensitivity of 0.0026 lx/ct allows the device to be placed behind dark cover glass.

Offering a high operating temperature range from -40 to +110 °C, the VEML4031X00 will be used for display backlight controls, infotainment systems, rearview mirror dimming, interior lighting control systems, and heads-up displays. The sensor supports the easy to use I²C bus communication interface for these applications and offers an interrupt function.

The VEML4031X00 features a supply voltage range of 2.5 V to 3.6 V, I²C bus voltage range of 1.7 V to 3.6 V and low shut down current consumption of 0.5 μA typical. RoHS-compliant, halogen-free, and Vishay Green, the device offers a Moisture Sensitivity Level of 2a and a floor life of four weeks in accordance with J-STD-020.

Samples and production quantities of the new ambient light sensor are available now, with lead times of 14 weeks. For more information, please visit https://www.vishay.com/en/product/80348/.
