PLEDxN Series Open LED Protectors from Littelfuse Ensure Remaining LEDs Stay Lit if a Single Device Fails
2017-04-24 | ReturnTheir small-footprint SOD-123FL package housing has one of the lowest height profiles (1.1 mm) of any device of this type, making it ideal for dense board applications that demand high layout flexibility.
Typical applications for PLEDxN Series of Open LED Protectors include street, subway, runway, and tunnel lighting, as well as headlights, roadside warning lights, and outdoor signage where high reliability and low maintenance are required.
“When compared with other open LED protection solutions such as Silicon Controlled Rectifiers (SCRs) and Zener diodes, the PLEDxN Series enables higher reliability and lower maintenance,” said Meng Wang, product manager, Open LED Protectors at Littelfuse. “That makes them ideal for applications like outdoor LED lighting or signage applications where durability is essential.”
PLEDxN Series Open LED Protectors offer these key benefits:
。Electronic shunt/bypass for open LEDs allows LED strings or arrays to continue to function even if one LED fails as an open circuit.
。The small-footprint SOD-123FL package provides high layout flexibility, making them ideal for dense board applications.
。Device resets automatically if the LED heals itself or is replaced, resulting in lower maintenance and higher reliability.
Availability
Surface mount PLEDxN Series Open LED Protectors are available in tape and reel packaging in quantities of 3,000. Sample requests can be placed through authorized Littelfuse distributors worldwide. For a listing of Littelfuse distributors, please visit Littelfuse.com.
