PLEDxSW White Body Open LED Protectors

Open LED protector from Littelfuse enhances reliability of LED strings

Image of Littelfuse's PLEDxSW White Body Open LED ProtectorsThe PLEDxSW series open LED protector from Littelfuse provides an electronic shunt path when an LED in an LED string fails as an open circuit. PLED devices are connected in parallel with each LED in a series string. If one LED fails as an open circuit, the PLED connected to it turns on and carries the current that would have gone through the failed LED. This keeps the rest of the string operating, so only a single LED goes dark rather than the whole string. The PLEDxSW has a molded white body that reflects more light to enhance overall light engine efficiency and is compatible with 1-, 2-, and 3-watt LEDs. Their low-profile, small-footprint package dissipates heat efficiently, so they’re ideal for use in dense board applications.

Features
  • Molded white body open LED protector
  • Electronic shunt / bypass for open LEDs
  • Small-footprint, low-profile DO-214AA package
  • Automatically resets if LED heals itself or the power is cycled
  • RoHS-compliant
Benefits
  • Protector is less visible in the LED fixture; reflects more light to enhance overall light engine efficiency
  • Remainder of LED string can continue to function even if one LED fails as an open circuit
  • Environmentally-friendly product
  • Standard SMB package provides layout flexibility; maximum heat dissipation makes it ideal for dense board applications
  • Low maintenance, high reliability
