What are the characteristics of ss14 Schottky diodes and how to detect them?

ss14 Schottky diode is a relatively common diode. The detailed information is: Schottky diode ss14 SMA 1A 40V. This type of Schottky diode is characterized by large current and fast working speed, but the reverse withstand voltage is small, and the reverse withstand voltage is 40V.

The ss14 Schottky diode uses a metal silicon junction, majority carrier conduction, low power consumption, high efficiency, and is widely used in surface mount applications. ss14 Schottky diodes can be used in low-voltage, high-frequency inverters, as well as free sliding and polarity protection applications.
 
Since the reverse withstand voltage of the ss14 Schottky diode is only 40V, it cannot be directly replaced with a general rectifier. For example, the 1N4007 rectifier tube has a large current and a slow speed, but its reverse withstand voltage is 1000V. If the two are used interchangeably, it is very easy to cause the SS14 to be broken down.
 
Many friends asked Meirui Electronics how to detect the quality of ss14 Schottky diodes. Today I will share with you the detection method of ss14.
 
Adjust the normal multimeter to the ohm Rx1K block, and measure the resistance of the ss14 Schottky diode. The forward resistance is in the range of tens to hundreds of ohms, and the reverse resistance is in the thousands of ohms, indicating that there is no problem with the quality of the ss14; The measured resistance values ​​are very large, which means that the ss14 Schottky diode is open or broken down; if the resistance values ​​are very small, it means that the ss14 is internally short-circuited.
 
The above is a brief introduction to the ss14 Schottky diode. If you want to know more detailed information, please call the contact number in the upper right corner, and Meirui Electronics will serve you wholeheartedly.
