The **C5SME-RJS-CS0U0BB2** is a high-brightness, through-hole LED manufactured by **Cree LED** (formerly Wolfspeed/Cree). It belongs to the Screen Master® series, specifically designed for outdoor video screens, digital signage, and traffic signals. --- ### 1. General Specifications This part is a **Red (628nm)** LED housed in a 5mm oval package. It is engineered to provide excellent light distribution and high durability in outdoor environments. | Parameter | Specification | | :--- | :--- | | **Color** | Red | | **Dominant Wavelength** | 624nm - 634nm | | **Luminous Intensity** | 770 mcd - 2130 mcd | | **Package Shape** | 5mm Oval | | **Viewing Angle** | 110° (Horizontal) / 50° (Vertical) | | **Lens Appearance** | Tinted & Diffused | | **Mounting Type** | Through-hole | --- ### 2. Key Electrical Characteristics Below are the typical operating parameters for this component: | Characteristic | Typical Value | Maximum Rating | | :--- | :--- | :--- | | **Forward Current ($I_F$)** | 20 mA | 50 mA | | **Forward Voltage ($V_F$)** | 2.0 V | 2.6 V | | **Reverse Voltage ($V_R$)** | - | 5 V | | **Power Dissipation** | - | 130 mW | | **Operating Temp** | -40°C to +100°C | - | --- ### 3. Application & Design Use-Cases * **Outdoor Signs:** Used in variable-message signs (VMS) on highways. * **Video Walls:** Ideal for full-color outdoor displays due to its specific viewing angle which minimizes "hot spots." * **Reliability:** The epoxy used is UV-resistant, preventing the lens from yellowing or becoming brittle when exposed to direct sunlight. --- ### 4. Part Number Breakdown The suffix **CS0U0BB2** defines the specific binning for this production run: * **CS0:** Part of the intensity and color bin grouping. * **U0:** Minimum Luminous Intensity (approx. 770 mcd). * **BB2:** Specific wavelength/color range and packaging (likely Ammo Pack or Bulk). ---
