marine electronis lesson 4

When we talk about a characteristic curve in electronics, we mean a graph showing the current (I) and voltage (V) behavior of the studied element. Therefore, here we observe the behavior of a diode. In other words, when the applied voltage changes, we see what happens to the current passing through it. In forward bias: Real diodes need a voltage higher than approximately 0.2V AND 0.6V for Germanium (Ge) and Silicon (Si) diodes, respectively, to operate. These voltages are also known as threshold voltages. Regardless of the current passing through them, diodes have a constant voltage drop across them, which is approximately 0.3V and 0.7V for Germanium (Ge) and Silicon (Si) diodes, respectively. In reverse bias: Standard diodes are designed to work in forward bias and do not allow current to flow in reverse bias. At very high reverse voltages, diodes experience breakdown, meaning that even a small change in voltage leads to a sharp increase in current. Standard diodes cannot reach this breakdown region as they are destroyed before reaching it. There is a special category of diodes called Zener diodes that are designed to operate in this breakdown region. Zener diodes are used as voltage reference sources in electronic circuits. 🔍 Book Preview (Google Books): 📖 https://books.google.com.cy/books/abo... 🛒 Buy the Book (Amazon): 🔗 https://a.co/d/2Z9vzE0 📥 Download the Full Book Now (PDF): 🔗 https://www.paypal.com/cgi-bin/webscr...
