SMD power LEDs exceptionally bright

7 May 2003 Opto-Electronics Products & Solutions

Four exceptionally bright, surface-mount, power LEDs featuring luminous intensity up to 1250 mcd at a 50 mA drive current have been released by Vishay Intertechnology. They complete Vishay's advanced TLMx33xx series with brilliant red, super red, soft orange, and yellow LEDs for automotive and outdoor applications. Built on high-efficiency AllnGaP technology, the TLMx33xx series devices are able to handle forward currents up to 50 mA in a standard PLCC-2 package outline measuring 3 X 2,8 mm. The new red (617 nm), soft orange (605 nm), and yellow (588 nm) LEDs are available in luminous intensity ranges of >200 mcd, 250 mcd to 640 mcd, 320 mcd to 800 mcd, and 400 mcd to 1250 mcd. Super-red (630 nm) LEDs are offered in intensity ranges of >160 mcd, 160 mcd to 400 mcd, and 250 mcd to 800 mcd. The TLMx33xx LEDs are luminous intensity, colour, and forward-voltage categorised per packing unit, ensuring even lighting. All four devices feature a 120° angle of half intensity and a lead-frame package embedded in a white thermoplast. The interior reflector is filled with a clear epoxy and operating temperature range is -40 to +100°C.
