Unidirectional device: LBP01-0803SC5
RoHS compliant
Benefits
Keep LED strings on in case of LED open
mode failure
Reduced maintenance cost
Increase lifetime of the lighting system
Complies with the following standards:
IEC61000-4-2 level 4
±15 kV (air discharge)
±8 kV (contact discharge)
IEC 61000-4-5
±1kV / 24 A
Applications
This device shunts failed LEDs in applications
where LED strings can not be turned-off for safety
reason due to a LED failure. Main applications
are:
Automotive headlights
Traffic lights
Aircraft runaway lights
Emergency lighting systems
Display panel backlighting
Street lighting

Description
The LBP01 series are bypass switches to be
connected in parallel with 1 or 2 LEDs. In case of
LED failure, this allows the current to flow through
the other LEDs.
It also provides an overvoltage protection against
surges defined in IEC 61000-4-2 and
IEC 61000-4-5
Their robust dice also protect LEDs against surge.
These devices are compatible with LEDs up to
1A.
LBP01 are packaged either in SMB or SOT23-5L
