The **AAAF3529VBDSEJ3ZGS** is a high-performance, surface-mount (SMD) **Tri-Color (RGB) LED** manufactured by Kingbright. It is designed to provide high-intensity light output across three primary colors within a single compact package. --- ## 1. Technical Specifications This LED integrates three independent chips (Blue, Red, and Green) that can be controlled separately to produce any color in the visible spectrum. | Parameter | Blue (InGaN) | Hyper Red (AlGaInP) | Green (InGaN) | |:---|:---|:---|:---| | **Wavelength (typ.)** | 470 nm | 625 nm | 525 nm | | **Luminous Intensity** | 150 - 300 mcd | 120 - 250 mcd | 400 - 700 mcd | | **Forward Voltage (typ.)** | 3.3V | 2.1V | 3.3V | | **Viewing Angle** | 120° | 120° | 120° | | **Lens Type** | Water Clear | Water Clear | Water Clear | --- ## 2. Pin Configuration and Internal Logic The device typically uses a **6-pin configuration** (common in the 3528/3529 metric footprint), allowing for independent anode and cathode control for each color. This is essential for Pulse Width Modulation (PWM) dimming. ### Internal Layout: * **Pins 1 & 6:** Blue Anode/Cathode * **Pins 2 & 5:** Red Anode/Cathode * **Pins 3 & 4:** Green Anode/Cathode *(Note: Always verify the specific polarity marking on the datasheet's mechanical drawing before PCB layout.)* --- ## 3. Key Features * **SMD Package:** 3.5mm x 2.8mm footprint (Standard 3528 size). * **ESD Sensitivity:** The Blue and Green chips are InGaN-based and sensitive to static; proper ESD precautions (HBM Class 1C) are required. * **Moisture Sensitivity:** Rated at **MSL 3**, meaning it requires vacuum packaging and controlled storage to prevent damage during reflow soldering. * **RoHS Compliant:** Lead-free and environmentally friendly. --- ## 4. Common Applications Due to its high brightness and small profile, this component is frequently used in: 1. **Backlighting:** Icons, switches, and control panels. 2. **Status Indicators:** Multi-color signaling for smart devices. 3. **Decorative Lighting:** Ambient lighting in automotive interiors or consumer electronics. 4. **Full-color Displays:** Small-scale matrix boards. ---
