Avago introduces high-power LEDs

The ASMT-JC11 and ASMT-AC00 1W LEDs are said to offer high lumens output and high energy efficiency in robust, small footprint packages to boost design flexibility.

This combination of features is ideal for traffic signals and the devices also address sign backlighting and architectural, commercial and decorative lighting applications.

The LEDs offer a footprint of 5mm x 4mm x 1.85mm for the ASMT-JC11 device's six-leaded small outline package (SOP).

Both devices can withstand maximum current of up to 500mA to provide high flux output performance of 58 lumens at 350mA.

The high flux output results in more efficient designs that use fewer LEDs to achieve an application's required lumens.

'Our new cyan LEDs position Avago to address the fast-moving transition from traffic signals using incandescent bulbs to more efficient, durable signals based on high-power LEDs,' said Francis Khor, director of marketing for the Optoelectronics Product Division at Avago.

Both LEDs feature an exposed thermal pad for efficient heat dissipation and low thermal resistance of 10C per watt.

High maximum allowable junction temperatures of 150C for the ASMT-JC11 device and 135C for ASMT-AC00 device enable the LEDs to be driven in stringent operating conditions, providing flexibility and reliability to lighting designs.

The devices offer an Electrostatic Discharge (ESD) resistance of 16kV, making them insensitive to ESD.

As a result, special ESD protection equipment is not required to handle the parts during installation.

The LEDs have an electrically neutral heat sink pad that allows them to be configured in an array using a common metal substrate without fear of electrical shorting, thus simplifying thermal design.
