Description
PLED Unidirectional Series (PLEDxxUx Series) open LED
protectors provide a switching electronic shunt path around
a single LED that fails as an open circuit. This ensures
the remaining string of LEDs will continue to function
even though a single LED in the string has failed open.
It also provides reverse battery or reverse power polarity
protection.
PLED Unidirectional Series devices were designed to
enable higher reliability in outdoor LED lighting applications
such as street lighting, outdoor signage, aircraft runway
lighting, roadside warning lights and other applications.
Compatible with one, two and three watt LEDs that have
a nominal 3V forward characteristic, PLED Unidirectional
Series devices are available in two surface mount packages,
the DO-214AA and the Quad Flat Pak No-lead (QFN). The
QFN’s low profile, chip scale package (CSP) is ideal for
dense board applications.
