High-brightness yellow and red SMD LEDs

11 June 2008 Opto-Electronics

Moving to meet the increasing demand for AlInGaP technology, Vishay has released two new series of yellow and red SMD LEDs in the reverse gullwing package that offer high brightness and low power consumption.

Featuring a low profile of 1,9 mm, the new VLRE31.. and VLRK31.. SMD LEDs offer top-down mounting and emit light through the PCB. The devices feature a non-diffused lens that is suitable for coupling to light pipes and backlighting.

The new LEDs are optimised for backlighting and illumination in automotive and transport, consumer, and general applications. Typical end products include handheld mobile devices, such as mobile phones and PDAs; switches and instrument panels; marker lights; audio and video office equipment; and signage and graphics.

The yellow VLRE31.. series offers a luminous intensity range from 112 mcd to 285 mcd, while the red VLRK31.. series features a 71 mcd to 285 mcd luminous intensity range. All devices offer a 30 mA forward current, with a 2,3 V forward voltage and 75 mW power dissipation. The LEDs provide an ESD-withstand voltage up to 2 kV in accordance with JESD22-A114-B.
