This PLED ultra-low holding current series exhibits a low holding current parameter that makes it compatible with LED lighting strings. The series provide a switching electronic characteristics for an fluorescent tube replacement by an LED string. It helps to make the Fluorescent ballast and LED string compatible with each other. This ensures the ballast will be able to activate the LED string; especially for those ballast that need a high voltage output detection during ignition.The PLED ultralow IH makes the LED driver widely used in the output of fluorescent tubes a compatible direct replacement for indoor and outdoor LED lighting strings.

The PLEDxUx Unidirectional Series Open LED Protector provides a switching electronic shunt path when one LED in a string fails as an open circuit. PLED devices are connected in parallel with each LED in a series string. If one LED fails as an open circuit, the PLED connected to it turns on and carries the current that would have gone through the failed LED, so the remainder of the string continues to function. LEDs cannot withstand voltages of reverse polarity; the PLEDxUX Series provides reverse battery/power polarity protection for greater LED reliability.

Automotive PLED Unidirectional Series (PLEDxUx-A) open LED protectors provide a switching electronic shunt path around a single LED that fails as an open circuit. This ensures the remaining string of LEDs will continue to function even though a single LED in the string has failed open. It also provides reverse battery or reverse power polarity protection. This series is designed for automotive applications such as automotive car head lamp, tail lamp, LED indicator protection, aircraft runway lighting and other applications need high reliability requirements.Compatible with one, two and three watt LEDs that have a nominal 3V forward characteristic.

The PLED5HT device is ideal for use in high reliability lighting applications such as traffic lighting, advertising lighting, and runway lighting.The PLED5HT protector provides three methods for increasing the reliability of LED lighting: LED failure protection: If one of the LEDs in an array fails open, the device provides a substitute electronic path so that the array continues to function ESD Protection: 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. Reverse battery and power protection: It provides protection in the case of accidental reverse battery or power connection.

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.

PLED6M Series from Littelfuse is designed to provide a switching electronic shunt path when an LED in an LED string fails as an open circuit. This ensures that the entire array of LEDs will stay illuminated even if a single LED in a string fails. The PLED6M Series is designed for use with one-watt LEDs, nominally 350mA @ 3V, and the low turn-on voltage of 7.5V (max) allows for fast switching after an LED opens. Furthermore, the on-state (bypass) voltage of 1.2V (max) reduces the steady state power dissipation following an LED open failure and is housed in a small form factor Powermite® package.
