PLEDxUSW 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. It is designed to enable higher reliability in outdoor LED lighting applications such as street lighting, outdoor signage, aircraft runway lighting, roadside warning lights and other applications. Additionally, it is molded from white material to make it less visible in the LED fixture and the white molding also reflects more light to improve overall light engine efficiency. Compatible with one, two and three watt LEDs that have a nominal 3V forward characteristic, PLEDxUSW is available in SMB surface mount package. The DO-214AA (SMB) low profile package is ideal for dense board applications.
