LED protection diode, PLED18US-A, 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. It is designed for automotive applications such as automotive car head lamps, tail lamps, LED indicator protection, aircraft runway lighting and other applications that require high reliability requirements. Compatible with one, two and three watt LEDs that have a nominal 3 V forward characteristic.
