Vishay
Intertechnology, Inc. unveiled two series of surface-mount, automotive-grade
power LEDs in PLCC-2 and ultra-compact MiniLED packages. The VLMx335xx and VLMx235xx series
deliver high brightness and a maximum drive current up to 50 mA
thanks to the latest advanced AllnGaP technology and smallest chip size
available, according to the company, targeting automotive, industrial, and
consumer applications.

The
AEC-Q101-qualified LEDs
offer low thermal resistance down to 400 K/W with power dissipation of 130 mW,
enabling the high drive current, said Vishay. The
devices offer an ESD-withstand voltage up to 2 kV in accordance with
JESD22-A114-B and are compatible with
preconditioning per JEDEC Level 2a.

The
VLMx235xx’s MiniLED package
(2.3 × 1.3 × 1.4 mm) and the VLMx335xx’s luminous
intensity of 1,400 mcd make them well-suited for a variety of applications, including
traffic lights, automotive
lighting (interior and exterior), LCD switches, and indicators and backlighting
for audio/video equipment.

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

The LEDs, available
in 8-mm tape, are RoHS-compliant, halogen-free,
and Vishay Green, a company designation in response to global
environment-related directives.

The VLMx335xx and VLMx235xx series will be available in the fourth quarter of 2018 with a lead time of six weeks. Pricing for U.S. delivery starts at $.047 per piece.
