How to Read Zener Diode Code

Many professionals do not know how to read a code Zener diode. There are many types of code that are fixed on the body. Appearance and shape of a Zener some time scanning to be wrong be a sign of a normal diode. To distinguish, seeks the code number on the body if it is a Zener diode, or LED. Thank you for producers that their main boards are printed with the word ZD , which refers to the Zener and D : a diode. But my experience printed circuit marked D can also represent Zener diode. It is an illusion to believe in a Zener diode is a technique. We as a technician or engineer must know or be sensitive to the mark. The only way to know is in reference to the code number printed on the body of the semiconductor element of a book of data. Without data book is very difficult to know the real tension of the Zener diode. If you do not produce data, you can go to the Google search engine and enter the following code and we hope you can answer this question! A Zener diode replacement in May led his team and sometimes malfunctions, and even helping his team. Time and money are lost because of lack of knowledge by finding the right Zener voltage. If you do not find the code, and you do not need to worry because this newsletter is there to guide you on how to read the code Zener diode. 5-1 = 5.1Volt Zener 5V1 Zener 5.1Volt = 12 = 12 Volt Zener 12V = 12 Volt Zener BZX85C22 = 22Volt 1 Watt Zener diode (see ECG Philips Semiconductors MASTER GUIDE REPLACEMENT) BZY85C22 = 22Volt 1 / 2 Watt Zener diode (see ECG Philips Semiconductors MASTER GUIDE REPLACEMENT) Note: There is also a room number, which BZVXXXXX where you have to find ECG book semiconductors. 1N4746 = 18 volts to 1 Watt Zener diode (see ECG Philips Semiconductors MASTER GUIDE REPLACEMENT) 6C2 = 6.2 volts Zener diode. (If you look at the Zener code is written in 6C2 reading from top to bottom) will not play at the top or bottom of the value you get is 2C6 you can not find the book! I think many wonder how will I live to the code of 6C2. They relate to the ECG book, you have to look for part numbers Hz That the average temperature instead of finding 6C2, HZ6C2 research and get the answer! The reduction of tension Zener that I found was 2.4 volts and the highest was 200 volts 5 watts. Conclusion be alert when control of part of a series of Zener diodes. Do not always think that a small diode signal is always a Zener diode. Look closely at the mark of the main card and read a portion of the Zener figures refer to book semi-conductors, preferably semiconductor book ECG data can be retrieved from local electronics. With this knowledge in mind, you can find success with the correct voltage of a Zener diode. Jestin Yong is an electronic workshop and a writer.
