Blue and true green LEDs in MiniLED packages
Latest Vishay SMD devices provide high luminous intensity to 2300 mcd
Vishay has introduced new blue and true green surface-mount LEDs in the ultra compact MiniLED package. Measuring 2.2 mm by 1.3 mm by 1.4 mm, the VLMB2332T1U2-08 and VLMTG2332ABCA-08 use ultrabright InGaN chip technology to achieve typical luminous intensity of 440 mcd and 2300 mcd, respectively, which is up to four times higher than previous-generation solutions in PLCC-2 packages.
The LEDs suit 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 525 nm at 20 mA, the VLMTG2332ABCA-0 suits heart rate monitoring applications in fitness trackers and other devices that rely on variations in green light absorption. Offering a typical wavelength of 465 nm at 20 mA, the VLMB2332T1U2-08 is optimised for smoke detectors that use 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 2.9 V typical. The VLMB2332T1U2-08 and VLMTG2332ABCA-08 are categorised, per packaging unit, for luminous intensity and colour.
