NUD4700

LED Shunt

The NUD4700 is an electronic shunt which provides a current bypass

in the case of a single LED going into open circuit. LEDs are by nature

quite fragile when subjected to transients and surge conditions. There

are also many cases where high reliability of the LED lighting must be

maintained such as headlights, lighthouses, bridges, aircraft, runways

and so forth. In these cases the low cost addition of the NUD4700 will

provide full assurance that an entire string of LEDs will not extinguish

should one LED fail. NUD4700 is also applicable to other loads where

circuit continuity is required. This device is designed to be used with

1 W LEDs (nominally 350 mA @ 3 V).
