PLED Open LED Protectors
PLED Series
PLED Series
RoHS
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.

5 LEDs and 1 PLED in Series 50% Duty Cycle 10kHz
Note:These two graphs show the current magnitude through the LED string with and without the PLED included. There is no noticeable effect on the LED current magnitude when the
PLED is included in the circuit as compared to the LED current magnitude when the PLED is not in the circuit. (The conversion factor for the test measurement in the graphs above is
10mA/mV for the Pearson coil measurement, therefore, the current magnitude in the first figure is 10mA*8.9 = 89mA, while the second figure is 91mA.)
