It maintains string continuity if an LED fails open, preventing the entire string from turning off.

Engineered protection for high-reliability LED lighting systems
What are Lighting Protection components?
Lighting protection components, such as LED shunt protectors, ensure system continuity by bypassing failed LEDs in a series string. They prevent open-circuit conditions that would otherwise disable the entire lighting array, critical for automotive and industrial reliability.
How to Choose Lighting Protection Components
Selection depends on the string configuration and the failure mode you need to mitigate.
String Voltage
Ensure the protector's breakdown voltage exceeds the operating voltage of the LED string.
Current Handling
Match the shunt current rating to the nominal forward current of your LED array.
Package Thermal
Verify the package can dissipate heat during a sustained bypass event.
Response Time
Fast response is critical to prevent driver damage during rapid transient events.
Failure Mode
Determine if you need a latching or non-latching protection mechanism.
