Malvern, Pa. A new miniature silicon NPN planar phototransistor from Vishay Intertechnology gives designers a low-cost solution for building backlit displays that respond automatically to changes in ambient light. The new miniature ambient light sensor, packaged in a 4 x 2-mm footprint, offers peak sensitivity of 570 nm.
Constructed with Vishay's PCB mold technology, the TEMT6000 surface-mount sensor is a low-cost device capable of serving as a daylight sensor for backlight dimming in mobile phones, notebook computers, PDAs, cameras, video cameras, dashboards, and plasma televisions. With an ultra-small footprint, Vishay Semiconductors' new sensor allows designers to save space or enhance the functionality of these systems.
The TEMT6000 sensor features a wide angle of half-sensitivity of ±60°. Although the device is highly sensitive to ambient light, it suppresses the infrared (IR) spectrum to offer improved "human eye"-like responsiveness to the visible light spectrum, said the company. The operating temperature range of the device is -40°C to 85°C.
The lead (Pb)-free TEMT6000 sensor is RoHS- and WEEE-compliant and is suitable for lead (Pb)-free IR reflow soldering processes with a solder temperature rating of 260°C.
Pricing for U.S. delivery is $35.00 per 100 pieces in quantities of 50,000. Samples and production quantities are available now with lead times of six to eight weeks for large orders.
