## Technical Overview: CLM2D-RPC-CXAZ0BB3 The **CLM2D-RPC-CXAZ0BB3** is a high-performance Surface Mount Device (SMD) Light Emitting Diode (LED) manufactured by **Cree LED** (formerly part of Wolfspeed). It belongs to the **CLM2D** series, which is specifically designed for high-reliability applications such as automotive signage and architectural lighting. --- ### 1. Key Technical Specifications Below are the primary electronic and optical characteristics for this specific part number: | Parameter | Specification | Details | | :--- | :--- | :--- | | **Color** | Red-Orange | Dominant Wavelength: 612nm - 624nm | | **Luminous Intensity** | 560 - 1400 mcd | Measured at 20mA | | **Forward Current ($I_F$)** | 20 mA (Nominal) | Maximum peak up to 50mA | | **Forward Voltage ($V_F$)** | 2.0V - 2.6V | Typical operating range | | **Viewing Angle** | 120 Degrees | Wide spatial radiation pattern | | **Package Type** | PLCC4 | 4-pin SMT package | | **Operating Temp** | -40°C to +100°C | Industrial/Automotive grade | --- ### 2. Electronic Architecture The "RPC" designation indicates the use of **AlGaInP** (Aluminum Gallium Indium Phosphide) material technology. This material is chosen for red/orange spectrum LEDs because it offers high luminous efficiency and stable performance over a wide temperature range. #### Pin Configuration The device uses a **PLCC4** footprint, but it is important to note the internal circuitry: * **Common Anode/Cathode:** While it has 4 pins, it typically functions as a single-color emitter. * **Heat Dissipation:** The 4-pin design allows for better thermal transfer to the PCB compared to standard 2-pin 0805 or 1206 LEDs. --- ### 3. Application Areas Due to its reliability and specific color point, this part is commonly used in: 1. **Automotive:** Dashboard backlighting, instrument clusters, and interior ambient lighting. 2. **Signage:** Full-color video screens and advertising displays (specifically for the red/orange channel). 3. **Industrial:** Status indicators for machinery where high visibility is required under sunlight. --- ### 4. Part Number Breakdown The suffix `CXAZ0BB3` provides specific binning information: * **C:** Color binning (Red-Orange). * **XA:** Minimum Intensity bin. * **Z0:** Maximum Intensity bin. * **B:** Wavelength range start. * **B3:** Packaging/Reel specifications. ---
