### Electronic Overview of CLP6C-RKW The **CLP6C-RKW** is a high-performance, Red, Surface Mount (SMD) Light Emitting Diode (LED) manufactured by **Cree LED** (formerly Wolfspeed/Cree). It belongs to the PLCC6 package family, known for high reliability and brightness. --- ### Technical Specifications The following table outlines the primary electronic and optical characteristics of the CLP6C-RKW: | Parameter | Specification | Unit | | :--- | :--- | :--- | | **Color** | Red | - | | **Dominant Wavelength** | 619 - 624 | nm | | **Luminous Intensity** | 710 - 2240 (Typical) | mcd | | **Forward Voltage ($V_F$)** | 2.1 (Typical) / 2.6 (Max) | V | | **Forward Current ($I_F$)** | 50 | mA | | **Reverse Voltage ($V_R$)** | 5 | V | | **Operating Temperature** | -40 to +100 | °C | | **Viewing Angle** | 120 | degrees | --- ### Key Electronic Features 1. **PLCC6 Package Construction:** * This LED utilizes a **Plastic Leaded Chip Carrier (PLCC6)** design. * Unlike standard 2-pin LEDs, the PLCC6 has **6 pins**. In the CLP6C-RKW, these are typically configured so that the single red chip is connected across multiple pins to improve thermal dissipation. 2. **Thermal Management:** * The 6-pin architecture allows heat to spread more efficiently into the Printed Circuit Board (PCB). * Effective heat sinking is crucial for this model because it operates at a higher current (50mA) compared to standard indicator LEDs (20mA). 3. **Encapsulation:** * It features a water-clear epoxy resin, which ensures high light output and a wide viewing angle of 120°, making it ideal for signage and backlighting. 4. **AllnGaP Technology:** * The semiconductor material used is **Aluminum Indium Gallium Phosphide (AlInGaP)**. This technology is responsible for the high efficiency and stable brightness levels in the red spectrum. --- ### Typical Applications * **Traffic Signaling:** Used in stoplights and pedestrian crossings due to its high intensity. * **Automotive Lighting:** Exterior turn signals, brake lights, and interior dashboard illumination. * **Channel Letters:** Commercial signage where high visibility is required. * **Amusement Lighting:** Decorative displays requiring robust environmental resistance. --- ### Circuit Considerations When designing a circuit for the CLP6C-RKW, ensure the following: * **Current Limiting:** Always use a series resistor to prevent the current from exceeding 50mA. * **Polarity:** Observe the notch on the corner of the package to identify the Cathode. * **PWM Dimming:** This LED is compatible with Pulse Width Modulation (PWM) for brightness control.
