Vishay Intertechnology, Inc. has announced the release of the industry’s first AEC-Q100 qualified rectangular ambient light sensor. The Vishay Semiconductors VEML4031X00 integrates an ambient light sensor (ALS) and a highly sensitive IR photodiode into a compact, opaque surface-mount package measuring just 4.38 mm × 1.45 mm × 0.6 mm. With a width half that of previous-generation devices, it enables easier integration into space-constrained applications, including bezel-less center control displays.
Engineered for high accuracy, the sensor’s spectral sensitivity closely aligns with that of the human eye, while the integrated IR channel supports differentiation between light sources. With a broad detection range of 0 lx to 172,000 lx, the VEML4031X00 resists saturation even in daylight. Its high sensitivity of 0.0026 lx/ct allows placement behind dark cover glass without compromising performance.
Designed for harsh environments, the sensor operates across a wide temperature range of -40 °C to +110 °C, making it ideal for display backlight control, infotainment systems, rearview mirror dimming, interior lighting control, and heads-up displays. The device supports the I²C communication interface for easy system integration and includes an interrupt function for efficient operation.
The VEML4031X00 operates with a supply voltage of 2.5 V to 3.6 V and an I²C bus voltage of 1.7 V to 3.6 V, with a typical shutdown current of just 0.5 μA. It is RoHS-compliant, halogen-free, and designated Vishay Green, offering a Moisture Sensitivity Level (MSL) of 2a and a four-week floor life per J-STD-020 standards.
Samples and production quantities of the VEML4031X00 are available now, with standard lead times of 14 weeks.
