PLEDxN
PLEDxN Series
Description
The open LED protector provides a switching electronic
shunt path when a single LED in an LED string fails as
an open circuit. This ensures the entire LED string will
continue to function even if a single LED in the string
does not. This provides higher reliable lighting functions
in applications such as headlights, aircraft lights, airport
runway lighting, roadside warning lights, etc. This
component is compatible with one watt rated LEDs with a
nominal 350 mA current at 3V. The SOD-123FL package is
one of the lowest height profiles (1.1 mm) packages offered
in the industry.
