PLEDxN series LED open circuit protector

The small SOD-123FL package is the lowest of its kind (1.1mm) in the same type of device, making it ideal for compact circuit boards with high layout flexibility requirements.

Typical applications for the PLEDxN series LED open circuit protector include street, subway, aircraft runway and tunnel lighting, as well as front lights, roadside warning lights and outdoor billboards that require high reliability and low maintenance rates.

"The PLEDxN series offers higher reliability and lower maintenance requirements than other LED open circuit protector solutions (such as thyristors (SCRs) and Zener diodes." Litwelfuse LED open circuit protector product manager Meng Wang Said. "This makes it ideal for outdoor LED lighting or sign applications that require extremely high durability."

PLEDxN series LED open circuit protectors have the following key advantages:

• The electronic shunt / bypass for the LED open circuit allows the entire LED string or array to continue operating when a single LED has an open circuit fault.

The small SOD-123FL package offers high layout flexibility and is ideal for dense board applications.

After the LED is self-healing or replaced, the device can be reset automatically, reducing maintenance costs and improving reliability.
