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.

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.)
