## SC08-11YWA Electronic Component Overview The **SC08-11YWA** is a high-efficiency Yellow LED numeric display manufactured by Kingbright. It is widely used in digital clocks, instrument panels, and electronic appliances. --- ### 1. Key Technical Specifications The following table outlines the fundamental electrical and physical characteristics of the SC08-11YWA: | Parameter | Specification | | :--- | :--- | | **Display Type** | 7-Segment Single Digit | | **Circuit Configuration** | Common Cathode | | **Color** | Yellow (GaP/GaP) | | **Character Height** | 0.8 inch (20.32 mm) | | **Peak Wavelength** | 590 nm | | **Forward Voltage (Typ)** | 2.1 V | | **Forward Current (Max)** | 30 mA | | **Luminous Intensity** | 3000 - 7000 µcd | --- ### 2. Physical Construction The device is designed for durability and visibility: * **Segment Material:** Gallium Phosphide (GaP) on a Yellow substrate. * **Surface Finish:** Usually features a grey face with white segments to provide high contrast when the segments are off. * **Package Type:** Through-hole (DIP) with standard pin spacing for PCB mounting. --- ### 3. Pinout & Internal Circuitry The "SC" prefix indicates a **Common Cathode** configuration. This means all the negative terminals (cathodes) of the individual segment LEDs are tied together to a single pin (or pins), while the anodes are controlled individually. #### Segment Layout Standard 7-segment labeling applies: * **A-G:** The seven segments forming the digit. * **DP:** Decimal Point. * **Common Pins:** Connected to the ground (GND) of the circuit. --- ### 4. Typical Application Example To drive this display using an Arduino or Microcontroller, you must use current-limiting resistors to prevent burning out the LEDs. ```cpp // Example: Displaying a '1' on SC08-11YWA (Common Cathode) // Pins B and C must be HIGH, others LOW. void setup() { pinMode(2, OUTPUT); // Segment B pinMode(3, OUTPUT); // Segment C } void loop() { digitalWrite(2, HIGH); digitalWrite(3, HIGH); } ``` --- ### 5. Features * Low current operation. * High light output. * Excellent character appearance. * Mechanically rugged. * RoHS compliant.
