PLEDxSW Series - White Body
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.

6 LEDs in Series 50% Duty Cycle 10kHz
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.)
