Kingtronics managed to reduce production cost for SOT-23 package diodes and transistors recently.
Would you like to share inquiry to check our latest best support ? 

As we all known, material supplies for diodes, bridges and transistors were unstable. The prices kept increasing accordingly.

Here is a good news to share with all our new and regular customers. :-)

Nowadays, we reached an agreement with material suppliers to provide special better offer some values with below packages based on considerable quantities.

Please take this opportunity to share us your request to cost down !

In 2021, we cannot support some of our standard values of diodes and transistors because of material shortage, especially SS, SK, MBR, SR series Schottky Barrier Rectifier and transistors.
Meanwhile, there was long lead time for other diodes & transistors.

It was a bit inconvenience for all of us.
Nowadays, the supplies for some material resume normal gradually recently.
We can support some previous invalid values now.
Which is delighted that the lead time for rectifiers is improved now.

Welcome to share us your demand !

1. Fast recovery diode
Fast recovery diode, FRD for short, is a semiconductor diode with good switching characteristics and short reverse recovery time. It has unidirectional conductivity like ordinary diodes. It is mainly used in electronic circuits of switching power supplies, pulse width modulators, inverters, etc. It is mainly used as high-frequency rectifier diodes, freewheeling diodes or damping diodes.

2. Schottky Barrier diode
The Schottky Barrier diode, abbreviated as SBD, is not made by using the principle of PN junction.
It is a semiconductor made by using metal as the anode and N-type semiconductor as the cathode, using the barrier formed on the contact surface of the two with rectification characteristics. A semiconductor device is
a kind of hot carrier diode.
Schottky diodes are mainly used in circuits as rectifier diodes, freewheeling diodes, protection diodes, etc., and are mainly used in low-voltage, high-current circuits, such as switching power supplies, Frequency converter, inverter, microwave communication.

3. Features of fast recovery diodes and Schottky Barrier diode
a. The reverse recovery time of fast recovery diodes is several hundred nanoseconds, while Schottky Barrier diode are faster than it, even several nanoseconds;
b. The reverse breakdown voltage of fast recovery diodes is high, generally higher than 200V, or even several thousand volts, while the reverse breakdown voltage of Schottky Barrier diodes is very low, generally below 100V, and some will be higher;
c. The power consumption of fast recovery diodes is relatively large, while Schottky Barrier diodes have short reverse recovery time, low loss and low noise.

Although the advent of the new coronavirus epidemic has hit the global economy, the home office and online teaching caused by the home epidemic prevention measures in various countries around the world have increased rapidly.
Whether you are working from home or studying online, you need to connect to the data center and public cloud services.
Connectivity becomes as important as water and electricity.
It drives the demand for the computer and server market.

In this disastrous Q1 2020, some chip manufacturers realized revenue growth...

According to the statistics of market research organization Omdia, the overall semiconductor industry revenue showed a slight decline in the first quarter of 2020, but the total revenue of the top ten chip suppliers in the world still achieved a growth of about 2%; including Intel , Samsung, Micron and other leaders, in the first quarter of 2020 revenue totaled 63.6 billion US dollars, an increase of 1.4 billion US dollars from the previous quarter.

When there is a challenge, there is a chance for electronics component field.
