LSPxxxxAJR 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 series 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.

Specifications are subject to change without notice.
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 series 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.
