Product Overview NUD4700: LED Shunt For complete documentation, see the data sheet Product Description 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 1W LEDs (nominally 350mA @ 3V). Features • • • • • A Simple Two Terminal Device Automatically Resets Itself if the LED Heals Itself or is Replaced ON-State Voltage Typically 1 V OFF-State Current less than 250 µA This is a Pb-Free Device Applications • • • • End Products LEDs where Preventive Maintenance is Non Practical LEDs with High Reliability Requirements Crowbar Protection for Open Circuit Conditions Overvoltage Protection for Sensitive Circuits • LED Headlights Part Electrical Specifications Product Compliance Status NUD4700SNT1G Pb-free Active Channel Polarity V(BR)DSS Min (V) ID Typ (A) 5.5 0.0001 Halide free For more information please contact your local sales support at www.onsemi.com Created on: 6/30/2016 rDS(on) Max (mΩ) PD Max (W) Package Type 1.56 POWERMITE-2
