PLED Series Open LED protectors provide a switching electronic shunt path when a single 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 watt LEDs that have a normal 350 mA, 3V characteristic, but can extend up to 1000 mA LED applications. The PLED Series is available in two surface mount packages, the DO-214 and the Quad Flat Pak Nolead (QFN™). The QFN's low profile, chip scale package (CSP) is ideal for dense board applications.
