Shunt protectors for sensitive LED lighting applications
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.
