New LED delivers typical luminous intensity levels of 1500mcd from a drive current of only 20mA. They provide twice the brightness of Toshiba's previous generation devices and are among the brightest white LEDs in the industry.

Toshiba America Electronic Components, Inc., (TAEC)* today announced new compact high-efficiency white light emitting diodes (LEDs) that provide twice the brightness of Toshiba's previous generation devices and are among the brightest white LEDs in the industry 1 available in this form factor. Developed by Toshiba Corp. (Toshiba), the new TLWK1100B LED delivers luminous intensity levels of 1500 millicandelas (mcd) from a drive current of only 20mA (typical value). The robust design makes it suitable for automotive lighting designs, LCD backlighting, panel indicators, and the replacement of incandescent bulbs in certain lighting applications.

The TLWK1100B is available in a standard PLCC2 surface-mount package that measures 3.2mm x 2.9mm x 1.9mm. The LED's high brightness white light output is a result of a combination of a blue InGaN (indium gallium nitride) LED and yellow-emitting phosphor. The device offers efficient operation with maximum power dissipation of just 114mW and typical forward voltage (VF) of 3.2V. Operating temperature ranges from -40°C to 100°C.

Toshiba TLWK1100B White LED Specifications:
Chromaticity coordinates: Cx : 0.3 Cy : 0.3
Luminous Intensity: 1500 mcd (typ). @ If = 20mA, 2000mcd (max.)
Viewing angle, typ.: 120 degrees
Pricing and Availability

The Toshiba TLWK1100B white LEDs are available now, with samples priced at $0.60/each.
