Vishay Intertechnology, Inc. of Malvern, Pennsylvania USA, introduced two new series of surface-mount automotive grade power LEDs. The LEDs come in PLCC-2 and ultra-compact MiniLED packages. The LED chips use advanced aluminum indium gallium phosphide (AlInGaP) technology in what Vishay says is the smallest chip size available. The VLMx335xx and VLMx235xx series boasts high brightness and a maximum drive current up to 50 mA for automotive, industrial, and consumer applications.
The AEC-Q101 qualified LEDs feature a thermal resistance as low as 400 K/W with a power dissipation of 130 mW, which enables their high maximum drive current. According to Vishay, the tiny 2.3 mm by 1.3 mm by 1.4 mm size of the VLMx235xx’s MiniLED package and its high luminous intensity of up to 1400 mcd make the LEDs perfect for automotive interior and exterior lights; traffic signals and signs; and backlighting and indicators for audio and video equipment, LCD switches, and symbols for general use.
Packed LEDs Come in Yellow, Soft Orange, Amber, Red, and Super Red
The VLMx335xx and VLMx235xx LEDs come in yellow, soft orange, amber, red, and super red, and they feature a lead-frame embedded in a white thermoplast with an inside reflector filled with clear epoxy. The devices provide a ± 60° angle of half-intensity, and provide a luminous intensity ratio per packing unit of 1.6, and they operate with a forward voltage as low as 1.8 V. The company categorizes the LEDs per packing unit for color and luminous intensity.
RoHS-compliant, halogen-free, and Vishay Green LEDs are available in 8 mm tape. They reportedly 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.
Vishay says it will make available samples and production quantities of the VLMx335xx and VLMx235xx series in the fourth quarter of 2018, with lead times of six weeks. Pricing for U.S. delivery starts at just $0.047 per piece.
