Vishay Intertechnology has introduced new blue and true green surface-mount LEDs in the compact MiniLED package.

Measuring 2.2 x 1.3 x 1.4mm, the Vishay Semiconductors VLMB2332T1U2-08 and VLMTG2332ABCA-08 utilise the latest ultrabright InGaN chip technology to achieve typical luminous intensity of 440mcd and 2,300mcd, 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 perfect choice for small scale, high power products that are expected to work reliably in arduous environments. 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.

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 utilise short wavelength blue light for the detection of small particles.

The LEDs' 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 categorised, per packaging unit, for luminous intensity and colour.

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 preconditioning 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.
