PLED6M Series - Open LED Protectors

This series is being discontinued. Not recommended for new designs. 

PLED6M Series from Littelfuse is designed to provide a switching electronic shunt path when an LED in an LED string fails as an open circuit. This ensures that the entire array of LEDs will stay illuminated even if a single LED in a string fails.  The PLED6M Series is designed for use with one-watt LEDs, nominally 350mA @ 3V, and the low turn-on voltage of 7.5V (max) allows for fast switching after an LED opens.  Furthermore, the on-state (bypass) voltage of 1.2V (max) reduces the steady state power dissipation following an LED open failure and is housed in a small form factor Powermite® package.

Features:

  • Electronic shunt/bypass for open LEDs, allowing LED strings to keep functioning, even if one LED in the set fails as an open circuit
  • Automatically resets if the LED heals itself or the power is cycled
  • Low profile, small footprint POWERMITE® package provides maximum heat dissipation and greater layout flexibility
  • Supports high-brightness, outdoor LED applications where high reliability and low maintenacnce are required
  • Environmentally friendly, RoHS compliant construction

Applications:

  • Street, subway, runway, and tunnel lighting
  • Vehicle headlights
  • Roadside warning lights
  • Outdoor signage
