LED protection diode, PLED18Q12, LITTELFUSE
The open LED protector provides a switching electronic shunt path when an LED in an LED string fails as an open circuit. This ensures that the remaining string of LEDs will continue to function if a single LED does not. The device was 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. Compatible with one, two and three watt LEDs that have a nominal 3 V forward characteristic.
