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.
Availability The Littelfuse PLED
6 Series open LED protector is now available for order and sample requests
through most authorized Littelfuse representatives and distributors
worldwide. For a listing of Littelfuse representatives and distributors,
