Blue and true green LEDs in miniLED package deliver high brightness in a small size

Vishay Intertechnology, Inc. 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 and VLMTG2332ABCA-08 use the latest ultrabright InGaN chip technology to accomplish typical luminous intensity 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 LEDs are the ideal choice for small-scale, high-power products that are expected to work reliably in arduous environments.

In addition, with a typical wavelength of 525nm at 20mA, the VLMTG2332ABCA-08 is ideal 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 optimised for smoke detectors that use short-wavelength blue light to detect small particles.

The LEDs' MiniLED package features a lead-frame embedded in a white thermoplast. The devices provide 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 categorised, per packaging unit, for luminous intensity and colour.

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

Typical applications will include medical light treatment; signal lights for agricultural equipment and energy generation systems; indicators and backlighting for office, entertainment, and telecommunications equipment; LCD switches; and symbols for general use.
