PLED Open LED Protectors PLED Series HF RoHS PLED Series Description The open LED protector provides a switching electronic shunt path when an LED in an LED array fails as an open circuit. This ensures that the entire array of LEDs will continue to function even if a single LED in the array does not. This provides higher reliable lighting functions in applications such as headlights, aircrafts, aircraft runway lighting, roadside warning lights, etc. This device is compatible with one, two and three watt LEDs that have a nominal 3V forward characteristic. The PLED series is 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 Agency Approvals - PENDING applications.

PLED Open LED Protectors PLED 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.)
