PLED Open LED Protectors PLED5HT SOT 89 Series PLED5HT SOT 89 Series RoHS Description This PLED5HT 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 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. 3) It provides protection in the case of accidental reverse battery or power connection. A Schematic Symbol L 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 PLED5HT. MT2 (Pin 1) PX5H Production Date Code Control Circuit 1 E B YYWW Littelfuse offers over current devices for implementation in power circuits that can also enhance the reliability of circuit operation.
