White LEDs double brightness from compact package

The Toshiba TLWK1100B is supplied in a standard PLCC2 surface mount package which measures just 3.2mm x 2.9mm x 1.9mm. Potential applications for the new device include panel indication, LCD backlighting and the replacement of incandescent bulbs in certain lighting applications. A robust design and an operating temperature range of -40°C to 100°C also make the TLWK1100B ideal for automotive lighting designs.
The new LED has employed a combination of a blue InGaN LED and yellow-emitting phosphor to provide the high brightness white light output. The device offers efficient operation with maximum power dissipation of just 114mW, and typical forward voltage (VF) is 3.2V.
