Smallest LED packaging aims at wearable-product designs

March 27, 2014 // By Graham Prophet
Plessey’s smallest-packaged MaGIC LED (Manufactured on GaN-on-Si I/C) is intended to meet the needs of the wearable electronics market.

The PLW138003 is a white LED in a 1005 SMT package designed specifically for the demand for ever smaller LED components producing highly collimated light. The dotLEDs weigh 0.2 milligrams and have a profile of 0.2mm.

The 1005-size (1.0mm x 0.5mm) is a standard electronic component size, handled by the common surface-mount machines used in high volume consumer electronics. The dotLED is 0.2mm in height and designed specifically for applications that demand low profile electronic components.

PLW138003, delivering up to 0.7 lm of white light with a 130deg viewing angle from a 5 mA drive current. A blue version, the PLB138003 is also available. Further additions to the dotLED family will be colour variants and a series in the larger 1608 footprint. Plessey also provides a range of blue LED dice for customers needing a further reduction in size: the PLB030003 ultra-thin die is just 200 x 200 x 75 µm.

Plessey's LEDs are produced using its proprietary MaGICtechnology, that uses standard silicon semiconductor production techniques
