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.
