PLED Open LED Protectors PLED Unidirectional Series PLED Unidirectional Series (PLEDxUx) RoHS Description PLED Unidirectional Series (PLEDxUx 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 Agency Approvals Series devices are available in two surface mount packages, the DO-214AA and the Quad Flat Pak No-lead (QFN). The Agency Agency File Number QFN’s low profile, chip scale package (CSP) is ideal for dense board applications.

PLED Open LED Protectors PLED Unidirectional Series 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.)
