PL IA NT CO M *R oH S Features Applications ■ Fast switching ■ LED streetlights ■ Automatic reset ■ LCD backlighting ■ SMB package ■ Display lighting ■ Suitable for industrial lighting environments ■ Intrinsically safe lighting ■ RoHS compliant* LSPxxxxBJR Series LED Shunt Protector General Information Bourns® LSP Series protectors are electronic shunts that provide a current bypass when an LED element in an LED string fails open circuit. This ensures the remaining string of LEDs will continue to function. There are many cases where high reliability of the LED lighting must be maintained, such as LCD backlighting, transport lighting, avionics, intrinsically safe and low maintenance lighting.

Customers should verify actual device performance in their specific applications. Note: The interaction between the Bourns® LSP device and the power supply for the LED string dictates the power supply architecture. Proper care must be taken in the design of the power supply architecture to ensure that the Bourns® LSP devices operate as intended and the design maintains integrity.
