Toshiba America Electronic Components Inc. (TAEC) has expanded its family of white LEDs with a new device that can provide a typical flux of 30 lumens from a driving current of 250mA. The TL12W01-D surface mount LED is well suited for many residential and commercial lighting applications that have used conventional incandescent bulbs. With dimensions of just 10.5mm x 5mm x 2.1mm, it is also targeted for space-limited applications that require high-brightness LCD backlighting.

Toshiba's TL12W01-D white LED also delivers typical performance of 35 lumens/W as a result of a low thermal resistance package that provides improved heat release characteristics. The forward voltage for the new device is rated at 3.4V (typical) at a forward current of 250mA. A wide operating temperature range of -40C to 100C enables use of these LEDs in a broad range of commercial, residential and industrial applications.

Designed for use with automated Pb-Free production lines, the surface mount device is compatible with reflow soldering processes at temperatures up to 260C.

"Toshiba recognizes the growing need for miniaturization of white LEDs coupled with high brightness and low power consumption. The TL12W01-D meets the requirements of various commercial lighting applications and has favorable power consumption characteristics," said Yoshimichi Sasaki, business development director, optoelectronics for TAEC. Demand for white LEDs is increasing for general lighting applications. White LEDs offer long operating life, low power consumption and compact size compared with incandescent and fluorescent lamps.

Samples of Toshiba's TL12W01-D are available now, priced at $2 each.
