PLED Open LED Protectors PLED5HT SOT-89 protector 31-12-2018 LFPCN41214 PLEDxN RoHS PLED5HT SOT-89 Protector Description This PLED5HT Open LED Protector component provides three methods for increasing the reliability of LED lighting: 1) If one of the LEDs in an array fails open, this component provides a substitute electronic path so that the array 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. A 3) It provides protection in the case of accidental reverse L battery or power connection. Schematic Symbol High reliability of lighting functions such as traffic lighting, MT1 (Pin 1) aircraft lighting, advertising lighting, and runway lighting PX5H B E K YYWW demand the use of a component such as the PLED5HT.
