Utilizing the latest advanced AllnGaP technology, the VLMx234.. series of power MiniLEDs have been made available by Vishay Intertechnology. The power MiniLEDs provides a typical luminous intensity of 3500 mcd and maximum luminous intensity of 4900 mcd at 70 mA while delivering improved thermal performance compared to previous-generation LEDs.

The LEDs provide low thermal resistance junction/ambient of 325 K/W and power dissipation up to 200 mW, which in turn enables high drive currents up to 70 mA. VLMx234.. devices feature a ± 60° angle of half-intensity and a luminous intensity ratio per packing unit of less than 1.6, and are categorized, per packing unit, for luminous intensity and color. Available in 8 mm tape, the LEDs are compatible with IR-reflow soldering processes and preconditioning according to JEDEC Level 2a, and offer an ESD-withstand voltage up to 2 kV according to JESD22-A114-B.

The devices' small size and high luminous intensity make them suited to automotive applications. Offered in super red, red, amber, and yellow, the AEC-Q101-qualified LEDs are ideal for interior and exterior lighting, dashboard illumination, indicators and backlighting for A/V and industrial equipment, LCD switches and symbols, illuminated advertising, and more.

The devices are RoHS-compliant, halogen-free, and Vishay Green. The are available in compact 2.3mm x 1.3mm x 1.4 SMD packages.
