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 LSP-Series open LED shunt protectors include four models: LSP0600BJR-S, LSP0900BJR-S, LSP1300BJR-S and LSP1800BJR-S. A maximum level of protection can be obtained by using one LSP0600BJR-S device per LED.
Alternatively, customers can reduce their protection costs by using the LSP0900BJR-S, LSP1300BJR-S or LSP1800BJR-S devices, that are able to isolate groups of two, three or four LEDs respectively. The devices come in an SMB surface mount package and are RoHS compliant.
