Automotive PLED Unidirectional Series (PLEDxUx-A)
Description
Automotive PLED Unidirectional Series (PLEDxUx-A) 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.
This series is designed for automotive applications such
as automotive car head lamp, tail lamp, LED indicator
protection, aircraft runway lighting and other applications
need high reliability requirements.
Compatible with one, two and three watt LEDs that have a
nominal 3V forward characteristic.
