67-235-YDGBGBC-B01E-ET8-CS

The 67-235-YDGBGBC-B01E-ET8-CS is a multi-chip surface-mount LED from Everlight Electronics’ 67-235 product series. Packaged in a compact PLCC-6 (5050 size, 5.0mm × 5.0mm × 1.4mm) SMD package, this LED integrates three independent LED chips, making it suitable for multi-color or multi-function lighting applications. The PLCC (Plastic Leaded Chip Carrier) construction provides excellent thermal performance through the heat-dissipating lead frame, enabling stable light output and long operating life. With a 120° viewing angle, these LEDs provide wide, uniform light distribution ideal for backlighting and indicator applications. The 67-235 series is designed for fully automated surface-mount assembly and is compatible with standard reflow soldering processes (260°C for 10 seconds). The ET8 packaging suffix specifies 8mm wide tape-and-reel packaging with 800 pieces per reel, optimized for high-volume pick-and-place manufacturing. Everlight’s rigorous quality control ensures tight binning for both color and brightness, ensuring consistent appearance across large production runs. These LEDs are RoHS compliant and lead-free, meeting global environmental requirements. Applications span consumer electronics backlighting, automotive interior ambient lighting, industrial status indicators, LED strip lighting, and display panel indicators.

LEDs (Light Emitting Diodes) are semiconductor devices that emit light when an electric current passes through them in the forward direction. This phenomenon is called electroluminescence. The LED chip is made from a semiconductor material (typically gallium arsenide phosphide, indium gallium nitride, or similar compounds depending on the desired color) doped to create a p-n junction. When forward voltage is applied across the p-n junction, electrons from the n-type region recombine with holes from the p-type region, releasing energy in the form of photons (light). The wavelength and color of the emitted light depend on the bandgap energy of the semiconductor material used. In a multi-chip package like the 67-235 series, three separate LED chips are mounted on a single lead frame within one package, with individual anode and cathode connections for each chip. The PLCC package uses a reflective cavity and encapsulant (typically epoxy or silicone) to efficiently extract and direct the light. The 120° viewing angle is achieved through the combination of the chip placement, reflector cavity shape, and lens/encapsulant geometry. For proper operation, the LED must be forward-biased with the anode at a higher potential than the cathode. A current-limiting resistor or constant-current driver is required to prevent overcurrent and ensure reliable operation.

Important: The 67-235 series contains three independent LED chips with separate anode and cathode connections. The exact pin assignment and chip configuration should be verified from the official Everlight datasheet for part number 67-235-YDGBGBC-B01E-ET8-CS before PCB design and assembly. Always connect a current-limiting resistor in series with each LED chip to control forward current.
