New power SMD LEDs in thermally enhanced PLCC-4 package
Vishay Intertechnology announced the release of a new series of power
surface-mount LEDs that deliver a significant advance in heat
dissipation and brightness. The new VLMx32.. devices feature a PLCC 4
package with a lead frame optimized to provide very low thermal
resistance down to 290 K/W and power dissipation up to 200 mW, which in
turn enables high drive currents up to 70 mA for twice the brightness
of Vishay’s high-intensity SMD LEDs in the PLCC 2 package. For
automotive applications, the VLMx32.. devices are automotive qualified
per AEC-Q101.
Available in amber and yellow, these new high-intensity LEDs are
intended for traffic signals and signs; interior and exterior lighting;
automotive interior and exterior lighting; indicators and backlighting
in audio and video, telecommunications, and office equipment; and flat
backlighting for illuminated advertising, LCDs, switches, and symbols
in general use.
Built on AllnGaP technology (ESD class 2), the LEDs released today
provide a high luminous intensity of 1400 mcd to 2850 mcd, with
dominant wavelengths of 610 nm to 621 nm for the amber devices, and 585
nm to 594 nm for the yellow devices. All VLMx32.. LEDs feature a
60° angle of half-intensity and a luminous intensity per packing
unit of less than 1.6, and are categorized, per packing unit, for
luminous intensity, color, and forward voltage, so they provide even
color and brightness.
The lead (Pb)-free and RoHS-compliant devices are available in 8 mm
tape and are suitable for lead-free reflow soldering according to CECC
00802 and J-STD-020B, and preconditioning according to JEDEC Level
2a.
