Vishay launches 440mcd blue and 2300mcd true green surface-mount LEDs in MiniLED package

Vishay Intertechnology Inc of Malvern, PA, USA has introduced new blue and true green surface-mount LEDs in the ultra-compact MiniLED package. Measuring 2.2mm x 1.3mm x 1.4mm, the Vishay Semiconductors VLMB2332T1U2-08 blue and VLMTG2332ABCA-08 true green LEDs utilize the latest ultra-bright indium gallium nitride (InGaN)-on-sapphire chip technology to achieve typical luminous intensities at 20mA of 440mcd and 2300mcd, respectively, which is up to four times higher than previous-generation solutions in PLCC-2 packages.

With their high brightness and small size, the new LEDs are suitable for small-scale, high-power products that are expected to work reliably in arduous environments. Typical applications include medical light treatment; signal lights for agricultural equipment and energy generation systems; indicators and backlighting for office, entertainment and telecoms equipment; LCD switches; and symbols for general use.

In addition, with a typical wavelength of 525nm at 20mA, the VLMTG2332ABCA-08 is suitable for heart rate monitoring applications in fitness trackers and other devices that rely on variations in green light absorption. Offering a typical wavelength of 465nm at 20mA, the VLMB2332T1U2-08 is optimized for smoke detectors that utilize short-wavelength blue light for the detection of small particles.

The MiniLED package features a lead-frame embedded in a white thermoplast. The devices offer a ±60° angle of half-intensity, a wide viewing angle of 120° for homogenous illumination and backlighting, and forward voltage of 2.9V typical. The VLMB2332T1U2-08 and VLMTG2332ABCA-08 are categorized, per packaging unit, for luminous intensity and color.

RoHS-compliant, halogen-free and Vishay Green, the LEDs are available in 8mm tape, offer an ESD-withstand voltage up to 2kV in accordance with JESD22-A114-B, and are compatible with pre-conditioning according to JEDEC Level 2a, IR reflow soldering according to J-STD-020, and automatic placement equipment.

Samples and production quantities of the VLMB2332T1U2-08 and VLMTG2332ABCA-08 are available now, with lead times of 12 weeks.
