3EZ20DE3/TR12 Application Field and Working Principle Diodes are electronic components used to direct current in one direction. Zener diodes are a type of diode that are specifically designed to work in reverse bias and allow current to flow in the opposite direction. The 3EZ20DE3/TR12 diode is one type of Zener diode, manufactured by JUANNJYE Technology Corporation. It is suitable for use in a wide range of applications including power supply, power management, and signal conditioning. This article will discuss the application fields and working principle of the 3EZ20DE3/TR12 diode. The 3EZ20DE3/TR12 is a low-voltage single Zener diode rated for 0.3 W, making it suitable for use in low-power circuits. This diode is typically used in applications that require accurate voltage regulation with minimal power loss. It is commonly used as a voltage reference in power supply designs, or for providing voltage or current limiting in signal conditioning applications. The 3EZ20DE3/TR12 diode also has a low threshold voltage, making it suitable for use in low-voltage applications. The working principle of the 3EZ20DE3/TR12 diode is based on the Zener effect discovered by physicist Dr.Karl Zener in 1934. The Zener diode allows current to flow in the opposite direction when connected in reverse bias. This reverse current is regulated by the Zener voltage, which is determined by the doping concentration of the diode. As the voltage increases, more current flows through the diode. When the applied voltage reaches the breakdown voltage, the current increases exponentially. The 3EZ20DE3/TR12 diode can also be used as a temperature sensor. In this application, the diode operates in reverse bias and the current increases exponentially with rise in temperature. This can be used to measure temperature changes with a high degree of accuracy, making it suitable for use in temperature sensing and regulation applications. To sum up, the 3EZ20DE3/TR12 is a low-voltage single Zener diode that is suitable for a wide range of applications including power supply, power management, and signal conditioning. It works on the principle of reverse bias and allows current to flow in the opposite direction when connected in reverse bias. The Zener voltage of the diode is determined by the doping concentration, and it can also be used as a temperature sensor.
