OPTEK develops 1W LED package with longer leads for improved stability on printed circuit boards

MUNICH, Germany, Providing lighting design engineers with a new package option for their high brightness surface mount 1-watt LED, TT electronics OPTEK Technology has developed a 1W surface mount LED package with longer leads than its original OVTL01LGA Lednium device.

Designated the OVTL01LGAxS Series, the new design allows the LED package to be mounted flat on a printed circuit board.

According to Richard Saffa, vice president of OPTEK Technology’s Visible LED Business Unit, the original 1W Lednium package design required an indentation in the PC board for the device to be mounted flat.  “The OVTL01LGAxS package features longer leads which allow the device to sit flatly on the printed circuit board,” Saffa explained.  “By not having to drill or alter the board, this new design saves engineers time and manufacturing cost, while improving the stability of the LED package on the PC board.”

The surface mount LED package offers high luminance, a full 140° viewing angle, features water clear lenses, and is available in amber, blue, green, red, cool white (7000K) and daylight white (5500K).   The device is ideal for a wide variety of solid-state lighting applications, including automotive interior and exterior lighting, architectural lighting, electronic signs and displays.

The OVTL01LGAxS Series LEDs exhibit DC forward current of 0.35A, with a peak pulsed forward current of 1A.  Typical forward voltage characteristics range from 2.0V to 3.3V (color-dependant), and reverse voltage for all devices is 5V.  Maximum allowable junction temperature is 130°C and the device features an ultra-low thermal resistance of 2°C/W.  Operating temperature range is -50°C to +85°C.

The OVTL01LGAxS Series packages measure just 6.00mm x 5.10mm x 1.56mm.

Typical pricing for the OVTL01LGAxS Series devices starts at $1.30 each in quantities of 10K pieces.  Production quantity lead times, if stock is not available, are from 8 to 10 weeks.
