Happy Moon Festival ! 
Kingtronics sales team

In order to express our appreciation to all valued customers, we have launched a new gift--diode M7 Bookmark Clip. 

Our previous souvenir mutil-tool knife is not available any more, but the bookmark clip has been endowed more Kingtronics characteristics. It is specially designed based on our M7 diode, including the color, appearance. Of course, Kingtronics logo and website can be also found on the bookmark clips. Hoping the new souvenir can win your affection! 

Please feel free to contact us and get them for free! Thanks!

Different types of diodes have different parameters.We must understand the following main parameters:

4. Reverse Current

Diode reverse current is at a temperature and a predetermined maximum reverse voltage is applied, current flows through the diode reverse. The smaller the reverse current, the conductive performance of the tube in one direction, the better. It is noteworthy that the reverse current and temperature are closely related, the temperature is increased by about 1 0 ℃, the reverse current increases doubled. For example 2APl type germanium diode, at 25 ℃, the reverse current of 250μA, the temperature rises to 35 ℃, reverse current will rise to 500μA, at 75 ℃, its reverse current has reached 8mA, not only lost a single direction of the conductive characteristics, the tubes will overheat and damage. Than the germanium diode silicon diode has good stability at high temperatures.

5. Reverse Recovery Time

From the forward voltage becomes a reverse voltage, ideally instantaneous cut-off current can, in fact, there are generally a little time delay. Determine the amount of current cut-off delay, that is the reverse recovery time. Although it directly affects the switching speed of the diode, but not necessarily say that this value is small enough.

6. Maximum Power

Maximum power is applied across the diode voltage multiplied by the current flowing. This limit is especially important parameter for regulator diodes.

About

Kingtronics International Company was established in 1995 located in Dongguan City of China to handle all sales & marketing for factories located in Chengdu, Sichuan and Zhaoqing, Guangdong, China. In 1990, we established the first factory to produce trimming potentiometer and in 1999 we built up new factory in Zhao Qing, Guangdong. Now with around 850 workers, Kingtronics produce trimming potentiometers, dipped tantalum capacitors, multilayer ceramic capacitors, and diode & bridge rectifier. We sell good quality under our brand Kingtronics, and Kt, King, Kingtronics are our three trademarks. All our products are RoHS compliant, and our bridge rectifier have UL approval. Please visit our Products page, you could please download all our PDF datasheet and find cross reference for our Trimming Potentiometer and capacitors.
