RoHS
PLED(R) Series
Description The open LED protector provides a switching electronic shunt path when an LED in an LED array fails as an open circuit. This ensures that the entire array of LEDs will continue to function even if a single LED in the array does not. This provides higher reliable lighting functions in applications such as headlights, aircrafts, aircraft runway lighting, roadside warning lights, etc. This device is compatible with one, two and three watt LEDs that have a nominal 3V forward characteristic. The PLED(R) is available in two surface mount packages, the DO-214 and the Quad Flat Pak No-lead (QFN). The QFN's low profile, chip scale package (CSP) is ideal for dense board applications.
