Device provides space-saving solution for sensing of visible light spectrum

Vishay Electronic : 24 September, 2004  (New Product)
A new miniature silicon NPN planar phototransistor that gives designers a low-cost way to build backlighted displays that respond automatically to changes in ambient light was announced today by Vishay Intertechnology, Inc.
A new miniature silicon NPN planar phototransistor that gives designers a low-cost way to build backlighted displays that respond automatically to changes in ambient light was announced today by Vishay Intertechnology, Inc.

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 measuring 4.0 mm by 2.0 mm, the Vishay Semiconductors TEMT6000 sensor allows designers to save space in or enhance the functionality of these systems.

The TEMT6000 sensor features a peak sensitivity of 570 nm and a wide angle of half-sensitivity of 60. Although the device is highly sensitive to ambient light, it suppresses the infrared spectrum to offer improved 'human eye'-like responsiveness to the visible light spectrum.

The TEMT6000 sensors are rated for an operating temperature range of -40 C to +85 C. These lead (Pb)-free devices are RoHS- and WEEE-compliant and are suitable for lead (Pb)-free IR reflow soldering processes with a solder temperature rating of 260 C.

Samples and production quantities of the new ambient light sensor are available now with lead times of 6 to 8 weeks for larger orders.
