Malvern, Pa. Vishay Intertechnology, Inc. says it has introduced the industry's first ambient light sensing photodiodes qualified to the automotive AEC Q101 standard, which is a reliability test qualification procedure for discrete semiconductors published by the Automotive Electronics Council. Automotive applications include rain, light, and tunnel sensors; brightness control for dashboard and navigation displays; and automatically turning on headlights at dusk.
The TEMD6010FX01 and TEMD5510FX01 ambient light sensors 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 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 0.1 lux to 100 klux 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. Vishay says competing sensors are unable to match this linear response at temperature extremes, particularly above +85°C.
The sensors are RoHS compliant, free of halogens, and compatible with lead (Pb)-free soldering.
Pricing: $0.66 for the TEMD5510FX01 and $0.53 for the TEMD6010FX01 for U.S. delivery in quantities of 5,000.
Availability: Samples are available now with lead times of six weeks.
