PLED Open LED Protectors PLED5 QFN Series RoHS Description This PLED5 Open LED Protector device provides three methods for increasing the reliability of LED lighting: 1) If one of the LEDs in an array fails open, this device provides a substitute electronic path so that the string continues to function. 2) It protects against ESD events up to ± 8 kV for contact discharges and ± 15 kV for air discharges per the IEC 61000-4-2 electrostatic immunity standard. 3) It provides protection in the case of accidental reverse battery or power connection. High reliability of lighting functions such as traffic lighting, aircraft lighting, advertising lighting, and runway lighting demand the use of a device such as the PLED5. Schematic Symbol MT1 Littelfuse offers overcurrent devices for implementation in power circuits that can also enhance the reliability of circuit operation.
