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).
