Shunt Protectors for Sensitive LED Lighting Applications
While low power LED string designs may have used zener diodes in this confi guration, high power LEDs would require very large and expensive zener diodes. Placing the Bourns® LSP device across LEDs allows the remaining LEDs in a series string to continue to work when an LED fails open circuit.
Features:
■ Fast switching
■ Automatic reset
■ SMB package
■ Suitable for industrial lighting environments
■ RoHS compliant*
Applications:
■ LED streetlights
■ LCD backlighting
■ Display lighting
■ Intrinsically safe lighting
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.
