Automotive Grade Power LEDs Exploit AllnGaP

Vishay Intertechnology’s two latest series surface-mount Automotive Grade power LEDs in PLCC-2 and ultra compact MiniLED packages employ the latest advanced AllnGaP technology. The VLMx335xx and VLMx235xx series deliver high brightness and maximum drive current up to 50 mA.

 

The AEC-Q101 qualified LEDs combine thermal resistance down to 400 K/W with power dissipation of 130 mW, which in turn enables their high drive current. The 2.3 mm by 1.3 mm by 1.4 mm size of the VLMx235xx's MiniLED package and VLMx335xx's high luminous intensity to 1,400 mcd make them viable for automotive interior and exterior lighting; traffic signals and signs; and indicators and backlighting for audio and video equipment, LCD switches, and symbols for general use.

Offered in super red, red, amber, soft orange, and yellow, the LEDs feature a lead-frame embedded in a white thermoplast, with an inside reflector filled with a clear epoxy. The devices offer a ± 60° angle of half-intensity, forward voltage down to 1.8 V, and a luminous intensity ratio per packing unit of ≤ 1.6, and they are categorized, per packing unit, for luminous intensity and color.

 

RoHS-compliant, halogen-free, and Vishay Green, the LEDs are available in 8 mm tape, offer an ESD-withstand voltage up to 2 kV in accordance with JESD22-A114-B, and are compatible with preconditioning according to JEDEC Level 2a.

 

 

Samples and production quantities of the VLMx335xx and VLMx235xx series will be available in Q4 2018, with lead times of six weeks. Pricing starts at $0.047 per piece. For more details, checkout the VLMx335xx and VLMx235xx datasheets.
