This document provides a comprehensive analysis and interpretation of the YSL-R531K3D-D2 red LED datasheet, expanding upon the limited information initially available. While the original datasheet from Young Sun LED Technology may be sparse, we can infer crucial characteristics and performance parameters based on industry standards, comparable LED models, and the provided context. Understanding these parameters is critical for proper selection and application of this component in various electronic designs.
1. Manufacturer and Product Line:
The YSL-R531K3D-D2 LED is manufactured by Young Sun LED Technology, a Chinese manufacturer specializing in LED components. The "YSL" prefix clearly identifies the manufacturer. The "R" designates the LED as red, and the remaining alphanumeric string likely represents internal part numbering, signifying specific physical dimensions, packaging type, and potentially internal construction details. The "-D2" suffix might indicate a specific binning or quality level, implying consistent performance within a defined range. This is common practice to ensure predictable characteristics across a production batch. Further investigation into Young Sun's product catalog would solidify these assumptions.
2. Physical Characteristics and Packaging:
The datasheet's lack of explicit detail requires us to make informed estimations. Based on the naming convention and common LED packaging, the YSL-R531K3D-D2 is likely a surface-mount device (SMD) in a standard package like a 0603, 0805, or potentially a slightly larger size. These package sizes are prevalent for LEDs, offering a balance between compactness and ease of handling during surface-mount assembly. The exact dimensions (length, width, and height), lead spacing (if applicable), and the type of lens (e.g., clear, diffused, water-clear) require reference to Young Sun's documentation or physical inspection of the component.
3. Electrical Characteristics:
This section attempts to reconstruct the missing electrical parameters, relying on typical values for similar red LEDs. While precise values will differ based on manufacturing tolerances and binning, we can establish expected ranges:
* Forward Voltage (Vf): Red LEDs typically operate with a forward voltage between 1.8V and 2.2V. The YSL-R531K3D-D2 would likely fall within this range, with the precise value dependent on the forward current (If). A higher forward current generally results in a slightly higher forward voltage.
* Forward Current (If): The maximum forward current (If(max)) is a critical parameter. Exceeding this value can lead to LED damage or premature failure. Typical values for small SMD LEDs range from 10mA to 30mA. The datasheet's absence necessitates a cautious approach, starting with lower current values during testing and gradually increasing to determine the optimal operating point. A recommended starting point would be 10-15mA.
