PLED6UQ12 | Littelfuse

LED protection diode, PLED6UQ12, LITTELFUSE

The open LED protector provides 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 to open. It also provides reverse battery or reverse power polarity protection. The devices were also 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.
