What is a Constant current diode?

A Constant Current Diode (Current Regulator Diode) is a semiconductor device that allows a consistent current to flow regardless of external circuit conditions. It is designed with an internal structure to regulate a fixed current and is typically used in series with a load. These diodes are commonly used for supplying constant current to LEDs, sensors, and actuators. By maintaining stable current despite variations in power supply voltage, they simplify circuit design and enhance efficiency.
Due to their compact size, lightweight nature, and high reliability, constant current diodes are widely used in portable devices, battery-operated systems, and for protecting analog circuits. They are particularly effective in preventing overcurrent, safeguarding circuits from overload conditions.
