PLEDxSW Series
PLEDxSW 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
devices are available in SMB surface mount package. The
DO-214AA (SMB) low profile package is ideal for dense
board applications.
