Description
PLED 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.
PLED 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 applictions.
Compatible with one, two and three watt LEDs that have
a nominal 3V forward characteristic, PLED Series devices
are available in two surface mount packages, the DO-214
and the Quad Flat Pak No-lead (QFN). The QFN’s low
profile, chip scale package (CSP) is ideal for dense board
applications.
