Ambient-Light Sensing for Automotive Applications

The TEMD6010FX01 and TEMD5510FX01 ambient-light sensing photodiodes are qualified to the Automotive Electronics Council' s AEC-Q101 standards.

These photodiodes use Vishay’s exclusive infrared-filtering epoxy technology to match the spectral sensitivity of the human eye with minimal sensitivity to light beyond the visible range. They also provide a similar response to either incandescent or fluorescent light, for which the TEMD6010FX01 and TEMD5510FX01 deliver response ratios of 1.3 and 1.4 respectively. For comparison, a standard silicon infrared photodiode has a response ratio of 10.

The TEMD6010FX01 and TEMD5510FX01 provide a linear response to illuminance from 0.1lux to 100klux with good lot-to-lot repeatability over the extended operating temperature range of -40°C to 100 °C. Lot-to-lot repeatability eliminates calibration steps in the manufacturing process. Competing sensors are unable to match this linear response at temperature extremes, particularly above 85°C.

Ambient light sensors are a key component for automotive body control and passenger safety applications. They allow electronic systems to detect and respond to light, eliminating the need for manual adjustments and reducing power consumption.
