PLED® Series
RoHS
HF
Description
The open LED protector provides a switching electronic
shunt path when an LED in an LED array fails as an open
circuit. This ensures that the entire array of LEDs will
continue to function even if a single LED in the array does
not. This provides higher reliable lighting functions in
applications such as headlights, aircrafts, aircraft runway
lighting, roadside warning lights, etc. This device is
compatible with one, two and three watt LEDs that have a
nominal 3V forward characteristic. The PLED® is available
in two surface mount packages, the DO-214 and the Quad
Flat Pak No-lead (QFN). The QFN’s low profile, chip scale
package (CSP) is ideal for dense board applications.
