The **KRTB-2AB-SSLASHQ** is a high-performance, surface-mount (SMD) **RGB LED** manufactured by **OSRAM Opto Semiconductors**. It belongs to the *Multi CHIPLED* family and is specifically designed for high-resolution displays, interior lighting, and status indication. --- ### 1. Technical Specifications The following table outlines the key electrical and optical characteristics for each color channel within the component: | Characteristic | Red (R) | True Green (T) | Blue (B) | | :--- | :--- | :--- | :--- | | **Material** | AlGaInP | InGaN | InGaN | | **Wavelength (typ)** | 623 nm | 525 nm | 465 nm | | **Luminous Intensity** | 180 - 450 mcd | 450 - 1120 mcd | 90 - 280 mcd | | **Forward Voltage (typ)** | 2.1 V | 2.9 V | 2.9 V | | **Max Forward Current** | 30 mA | 25 mA | 25 mA | --- ### 2. Physical Construction & Design The "SSLASHQ" suffix often refers to the specific binning and packaging configuration. Key physical features include: * **Package Size:** Typically **1.6 mm x 1.6 mm** (1616 footprint) with a low profile height of approximately 0.7 mm. * **Common Anode/Cathode:** It features a 4-pin or 6-pin configuration (depending on the specific sub-variant) allowing independent control of the three colors. * **Encapsulation:** Clear silicone or epoxy resin is used to provide a wide viewing angle (typically **120°**). * **Black Surface:** Many versions in this series feature a black package body to improve contrast ratios in video walls and display screens. --- ### 3. Key Electronic Features * **Individual Addressability:** Because it contains three separate chips (Red, Green, Blue), the color can be mixed to create any spectrum, including white, by using **PWM (Pulse Width Modulation)** on each channel. * **ESD Protection:** Most modern OSRAM CHIPLEDs include integrated ESD protection diodes (up to 2kV) to protect the sensitive InGaN (Blue/Green) chips. * **Thermal Management:** The small footprint requires careful PCB heat sinking if all three channels are driven at maximum current simultaneously. --- ### 4. Common Applications 1. **Full-color Video Walls:** Used in indoor LED billboards due to the high contrast and small pitch. 2. **Automotive Interior:** Ambient lighting in dashboards or door panels. 3. **Consumer Electronics:** Backlighting for buttons, status indicators on smart home devices, and wearable tech.
