Littelfuse PLED Open LED Protectors

PLED


Littelfuse PLED Series Open LED Protectors provide a switching electronic shunt path when an LED in an LED array fails as an open circuit, ensuring that the entire array of LEDs will continue to function even if a single LED in the array doesn't. PLED Series Open LED Protectors provide higher reliability lighting functions in applications such as headlights, aircraft, aircraft runway lighting, roadside warning lights, and more. These Littelfuse LED protection devices are compatible with 1, 2, and 3W LEDs that have a nominal 3V forward characteristic. Littelfuse PLED devices are available in a variety of package types, including QFN and DO-214 surface mount packages, SOT-89, and the small form factor Powermite® package.

PLED Features
  • Fast Switching
  • Automatically resets after power cycle
  • Available in low profile packages
  • Compatible with industrial lighting environments
  • Compatible with PWM dimming speeds of up to 10 KHz
  • RoHS compliant and halogen-free

PLED 5 QFN


Littelfuse PLED5 QFN protector provides three methods of increasing the reliability of LED lighting: - If one of the LEDs in an array fails open, this device provides a substitute electronic path so that the array continues to function - It protects against ESD events up to ± 8 kV for contact discharges and ±15 kV for air discharges per the IEC 61000-4-2 electrostatic immunity standard. - It provides protection in the case of accidental revers battery or power connection. High reliability of lighting functions such as traffic lighting, advertising lighting, and runway lighting demand the use of a device such as the PLED5.

PLED 5 QFN Specific Features
  • Reverse Battery / Power Protection
  • Surge Capability >24 A (8/20 µS)
  • ESD, IEC 61000-4-2, ±8kV contact, ±15 kV air
  • Open LED bypass up to 500 mA
  • Resets After Power Cycle
  • Low Turn-On (Trigger Voltage)
  • Ideal for MR16, PAR type lamps

New! - PLED6M


Littelfuse PLED6M LED Protector 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.

PLED6M Specific 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
  • 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 maintenance are required
  • Environmentally friendly, RoHS compliant construction

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

PLEDxSW Series - White Body


Littelfuse PLEDxSW Open LED Protectors offer a switching electronic shunt path when an LED in an LED string fails as an open circuit. PLEDxSW Open LED Protectors ensure the remaining string of LEDs continues to function even if a single LED does not. These devices automatically reset if the LED heals itself or the power is cycled.

Designed using white materials for less visibility in the LED fixture, the devices feature white molding to reflect more light and improve overall light engine efficiency. Compatible with one, two and three watt LEDs that have a nominal 3V forward characteristic and PWM frequencies up to 30 kHz, PLEDxSW Series devices are available in SMB surface mount package.

With a DO-214AA (SMB) low profile package, the PLEDxSW Open LED Protectors are ideal for dense board applications such as indoor lights, aircraft / runway lights, advertisement lighting, and other indoor LED lighting applications.

PLEDxUx


PLED Unidirectional Series (PLEDxUx Series) open LED protectors provide a switching electronic shunt path around a single LED that fails as an open circuit. This ensures the remaining string of LEDs will continue to function even though a single LED in the string has failed open. It also provides reverse battery or reverse power polarity protection.

PLED Unidirectional Series devices were designed to enable higher reliability in outdoor LED lighting applications such as street lighting, outdoor signage, aircraft runway lighting, roadside warning lights and other applications.

Compatible with one, two and three watt LEDs that have a nominal 3V forward characteristic, PLED Unidirectional Series devices are available in two surface mount packages, the DO-214AA and the Quad Flat Pak No-lead (QFN). The QFN's low profile, chip scale package (CSP) is ideal for dense board applications.
