Ensure Longevity and Reliability of LED Arrays with the New PLED®6 Family of Protectors

Protect Critical LED Lighting Applications

Like all electronics, LEDs are vulnerable to failure due to surges and other transients conditions. These failures can result in the loss of LED lighting strings, which can be dangerous in critical applications such as street, airport or emergency lighting. The new Littelfuse PLED 6 Series is an electronic shunt which offers a current bypass in the case of a single LED going into an open circuit condition.

Littel Fuse, the leaders 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.

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.

Features:

• RoHS compliant
• Chip Scale Package (CSP)
• Small footpring (QFN)
• SIDACtor® brand technology
• Compatible to industrial lighting environments
• Compatible with switching speeds up to 10kHz
• Automatically resets after power cycle
  

The PLED6S Open LED Protector Switching Thyristor comes in a DO-214AA package.
