PLED Open LED Protectors PLEDxSW Series RoHS PLEDxSW Series - White Body 41325 03/26/2020 PLED series Description PLEDxSW Series open LED protectors provide a switching electronic shunt path when an LED in an LED string fails as an open circuit. This ensures that the remaining string of LEDs will continue to function if a single LED does not. PLEDxSW Series devices were designed to enable higher reliability in indoor LED lighting applications such as advertisement lighting and other applications. Additionally, they are molded from white material to make them less visible in the LED fixture and the white molding also reflects more light to improve overall light engine efficiency. Compatible with one, two and three watt LEDs that have a nominal 3V forward characteristic, PLEDxSW Series Agency Approvals devices are available in SMB surface mount package. The DO-214AA (SMB) low profile package is ideal for dense Agency Agency File Number board applications.
