This PLED5 protector provides three methods of increasing the reliability of LED lighting: - If one of the LEDs in an array fails open, this device provides a substitute electronic path so that the array continues to function - 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. - It provides protection in the case of accidental revers battery or power connection. High reliability of lighting functions such as traffic lighting, advertising lighting, and runway lighting demand the use of a device such as the PLED5.
