Shunt Protectors suit sensitive LED lighting applications.
February 16, 2011 -
By shunting current around inoperable LED in light string, LSP-Series enables unaffected lights in string to remain illuminated. Models LSP0600BJR-S, LSP0900BJR-S, LSP1300BJR-S, and LSP1800BJR-S are capable of isolating 1, 2, 3, and 4 LEDs, respectively. Available in SMB surface mount packages, RoHS-compliant devices are suited for light bulbs, lighting fixtures, and backlighting systems.

Bourns Announces New Line of Shunt Protectors Designed Specifically for Sensitive LED Lighting Applications
Bourns® LSP-Series Devices Innovatively Shunt Current Making LED Applications More Robust for Improved Reliability and Lower Costs
RIVERSIDE, Calif., - Bourns, Inc., a leading manufacturer and supplier of electronic components, today announced a new line of open LED shunt protection devices designed specifically for LED lighting applications. Designated the Bourns® LSP-Series, the new shunt protector family enables LED lighting applications configured in strings to be more robust and reliable. Most LED designs include solid-state lighting luminaries configured in series strings of 20 or more LEDs. In this configuration, an open LED can cause the entire LED string to go dark, resulting in reduced performance and possible maintenance calls and costly warranty returns. Adding a Bourns® LSP-Series shunt protector to an LED design allows the unaffected lights in the string to remain illuminated by shunting current around the inoperable LED. The new LSP-Series of open LED shunt protectors are an optimal solution for a variety of LED lighting applications including light bulbs, lighting fixtures and backlighting systems.
"LED lighting applications are exploding in volume," said Ian Doyle, product line manager of semiconductor products at Bourns, Inc. "Bourns' new LSP-Series of open LED shunt protectors address the failure rates of early LED designs. Incorporating a Bourns® LSP device into the design of LEDs improves reliability and helps eliminate costly downtime."
The Bourns® LSP-Series of open LED shunt protectors include four models: LSP0600BJR-S, LSP0900BJR-S, LSP1300BJR-S and LSP1800BJR-S. Customers can maximize the level of protection by selecting Bourns® model LSP0600BJR-S and using one device per LED. Alternatively, customers can reduce their protection costs by selecting Bourns® models LSP0900BJR-S, LSP1300BJR-S or LSP1800BJR-S that are able to isolate groups of two, three or four LEDs respectively. Bourns' new device family comes in an SMB surface mount package and is RoHS* compliant. Product samples are available now through Bourns' distribution partners. As a pricing example, Bourns® LSP0600BJR-S is priced at $.30 each in 10K piece quantities.
