A laser diode is a semiconductor device that emits coherent light through the process of stimulated emission. It operates similarly to a light-emitting diode (LED) but produces a focused, monochromatic, and coherent beam of light. The emitted light waves have the same wavelength, frequency, and phase. The laser diode was invented by Theodore H. Maiman, […]
Photodiode is a crucial component in modern electronics, enabling devices to detect and respond to light. From remote controls and light meters to solar panels and advanced optical communication systems, photodiodes play a silent but powerful role in shaping how we interact with technology. In this article, we’ll explore everything you need to know about […]
Constant Current Diode (CCD) (also known as Current Regulator Diodes, or simply CRDs) are unique semiconductor devices designed to maintain a constant current over a wide range of voltages. They are extremely useful in circuits where a stable and predictable current is crucial, regardless of voltage variations. In this article, we will cover the Symbol, […]
The avalanche diode is a specialized type of semiconductor diode designed to operate in the reverse breakdown region without getting damaged. It plays a critical role in protecting electronic circuits from high voltage spikes and is commonly used in voltage regulation and surge protection applications. This article explores the avalanche diode in depth, from its […]
Diodes are semiconductor devices that allow current to flow in only one direction. They are widely used in modern circuits for applications such as switching, rectification, and protection. Among the various types of diodes, the fast recovery diode (FRD) is specifically applicable in high-frequency applications due to its fast reverse recovery time. When a diode […]
The tunnel diode, also known as the Esaki diode, is a type of semiconductor diode that exhibits a unique behavior due to quantum mechanical tunneling. Leo Esaki invented the tunnel diode in 1957, and he received the Nobel Prize in Physics for it in 1973. Its negative resistance region in the current-voltage (I-V) characteristics makes […]
