* Question
| What are the identification methods for commonly used Zener diodes? |
* Answer
| The Zener diode is commonly used in the circuit with “ZD” plus a number, such as: ZD5 represents the voltage regulator number 5.1. The voltage regulation principle of the Zener diode: The characteristic of the Zener diode is that after the breakdown, the voltage at both ends remains basically unchanged.Among the three types of faults, the former fault shows a rise in the power supply voltage; the latter two faults show that the power supply voltage goes low to zero volts or the output is unstable.The types and voltage regulation values of commonly used Zener diodes are as follows: Model 1N47281N47291N47301N47321N47331N47341N47351N47441N47501N4751 |
