PLED6M

PLED Open LED Protectors PLED6M Series PLED6M Series RoHS Description The open LED protector provides a switching electronic shunt path when an LED in an LED string 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, aircraft lights, airport runway lighting, roadside warning lights, etc. This device is designed to be used with one watt LEDs, nominally 350mA @ 3V, and is available in POWERMITE®* package (CSP) which is ideal for dense board applications.
