Open LED Protector increases LED lighting array reliability.October 31, 2008 -
Available in DO-214 or QFN SMT package, PLED® 6 Series provides switching electronic shunt path when single LED in LED array fails as open circuit. This ensures entire array of LEDs will continue to function, even if one LED in array does not. In addition to built-in surge immunity, protector has 4-layered thyristor structure that automatically resets if LED heals itself or is replaced. Featuring current range of 300 mA to 1.0 A, RoHS compliant unit has on-state voltage of 1.5 V.

New Littelfuse Introduces Reliable, Low-Cost Open LED Protector
New PLED® 6 Series open LED protector adds high-reliability to LED lighting, and is available in a DO-214 or QFN surface-mount package.
DES PLAINES, IL - October 21, 2008 - Littelfuse, Inc. (NASDAQ/NGS:LFUS) the leader in circuit protection, has introduced the PLED 6 Series, an open LED protector that provides a switching electronic shunt path when a single LED in an LED array fails as an open circuit. This ensures that the entire array of LEDs will continue to function even if a single LED in the array does not.
The Littelfuse PLED 6 Series open LED protector helps LED lighting manufacturers design for critical-reliability, hostile-environment applications such as automotive headlights, traffic lights, bridge lighting, and aircraft runway lighting. In these applications, light replacement is costly; open LED protection preserves the advantages of long-life LED technology and helps end users avoid high maintenance costs.
The new LED open circuit protector features a current range of 300mA to 1.0A, the highest current range on the market. It also features a low on-state voltage of 1.5V and low off-state current which lowers power dissipation and reduces the impact of heating on LEDs, which are delicate solid-state devices and can be easily damaged by current surges and transients. Such protection is especially important in a growing LED market that reached $4.2 billion in 2006 and is expected to grow to upwards of $9 billion by 2011.
The PLED 6 Series open LED protector uses a 4-layered thyristor structure that automatically resets if the LED heals itself or is replaced and also features built-in surge immunity. Its environmentally friendly package is RoHS compliant and halogen free as well.
The PLED 6 Series open LED protector is available in two surface mount packages, the DO-214 and the Quad Flat Pak No-lead (QFN). The QFN's low profile, chip scale package (CSP) is ideal for dense board applications as well as strings of LED lighting.
