Remain in light

Vishay Intertechnology, Inc has announced the release of a new family of high-intensity low-current, single-digit, seven-segment displays that can be read in direct sunlight.

The new Vishay Semiconductors TDSR series displays, utilising AllnGaP technology in the colour red, reportedly offers ‘best-in-class’ performance for very low-power applications, delivering a typical luminous intensity of 1500 µcd while being driven with 1 mA of current.

Featuring a wide viewing angle, the new displays will be used in panel meters, test and measurement equipment, point-of-sale terminals, control units, and battery-operated systems requiring very low power consumption.

The six TDSR displays are said to offer designers a choice of common anode (TDSRxx50) or common cathode (TDSRxx60) versions with minimum and maximum luminous intensity ratings from 180 µcd to 3600 µcd respectively, enabling operation in direct sunlight or in “black front” designs using tinted filter glass. A maximum forward current of 10 mA is allowed for an ambient temperature range of -40 degrees C to +85 degrees C without current derating.

Package dimensions for the new displays are 7.4 mm by 9.9 mm by 9.1 mm deep (TDSR0750 and TDSR0760), 9.7 mm by 12.8 mm by 10.7 mm deep (TDSR1050 and TDSR1060), and 12.25 mm by 17.5 mm by 10.6 mm deep (TDSR1350 and TDSR1360) with a grey package surface.

Samples and production quantities of the new seven-segment displays are available now with lead times of four weeks.
