PLED Open LED Protectors High power PLED PLEDxUSWxA Series - Unidirectional, White Body e3 RoHS Description PLEDxUSWxA 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. The devices is designed to enable higher reliability in indoor LED lighting applications such as advertisement lighting and other applications. Additionally, it is 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, PLEDxUSWxA is available in SMB surface mount package. The DO214AA (SMB) low profile package 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.)
