LED die expands scope for wearable products

The colour choice of dotLEDs from Plessey Semiconductors has been expanded. The selection, includes red, green and blue for the die which has a footprint of 0.2 x 0.2mm, a suitable low profile for wearable devices, says the company.

The white dotLED is available in a 1005 SMT package (1.0 x 0.5mm), which is a standard electronic component size that can be handled by standard surface-mount machines used in high volume, consumer electronics manufacturing. Delivering up to 1.0Lm of white light with a 130° viewing angle from a 5mA drive current, the PLW13D003 meets the demand for ever smaller displays. A blue version, the PLB13D003 is also available in a variety of wavelengths from 460 to 480nm.

The company has developed its first chip scale package, which will be sampling in September, with a selection of temperatures and colours.
