A key component for automotive body control and passenger safety applications, ambient light sensors allow electronic systems to detect and respond to light in a manner similar to the human eye, eliminating the need for manual adjustments and reducing power consumption.

The TEMD6010FX01 and TEMD5510FX01 use Vishay’s exclusive infrared filtering epoxy technology to match the spectral sensitivity of the human eye with minimal sensitivity to radiation beyond the visible range. For automotive applications, these surface mount ambient light sensing photodiodes are also qualified to the AEC-Q101 standard, a reliability test qualification procedure for discrete semiconductors published by the Automotive Electronics Council. Their automotive applications include rain, light and tunnel sensors; brightness control for dashboard and navigation displays; and automatically turning on the headlights at dusk.

These photodiodes provide the benefit of having a similar response to either incandescent or fluorescent light, for which the TEMD6010FX01 and TEMD5510FX01 deliver excellent response ratios of 1.3 and 1.4 respectively. For comparison, a standard silicon infrared photo diode 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 may allow customers to eliminate calibration steps in their manufacturing process. Competing sensors are unable to match this linear response at temperature extremes, particularly above 85°C.
