WEET: 2017 Annual Semiconductor Sales Increase 21.6 Percent, Top $400 Billion for First Time

We are WEE, We Enhance Efficiency 

Global semiconductor industry posted sales totaling $412.2 billion in 2017, the industry’s highest-ever annual sales and an increase of 21.6 percent compared to the 2016 total. Global sales for the month of December 2017 reached $38.0 billion, an increase of 22.5 percent over the December 2016 total and 0.8 percent more than the previous month’s total. Fourth-quarter sales of $114.0 billion were 22.5 percent higher than the total from the fourth quarter of 2016 and 5.7 percent more than the third quarter of 2017. Global sales during the fourth quarter of 2017 and during December 2017 were the industry’s highest-ever quarterly and monthly sales, respectively. 

Several semiconductor product segments stood out in 2017. Memory was the largest semiconductor category by sales with $124.0 billion in 2017, and the fastest growing, with sales increasing 61.5 percent. Within the memory category, sales of DRAM products increased 76.8 percent and sales of NAND flash products increased 47.5 percent. Logic ($102.2 billion) and micro-ICs ($63.9 billion) – a category that includes microprocessors – rounded out the top three product categories in terms of total sales. Other fast-growing product categories in 2017 included rectifiers (18.3 percent), diodes (16.4 percent), and sensors and actuators (16.2 percent). Even without sales of memory products, sales of all other products combined increased by nearly 10 percent in 2017.  

Annual sales increased substantially across all regions: the Americas (35.0 percent), China (22.2 percent), Europe (17.1 percent), Asia Pacific/All Other (16.4 percent), and Japan (13.3 percent). The Americas market also led the way in growth for the month of December 2017, with sales up 41.4 percent year-to-year and 2.1 percent month-to-month. Next were Europe (20.2 percent/-1.6 percent), China (18.1 percent/1.0 percent), Asia Pacific/All Other (17.4 percent/0.2 percent), and Japan (14.0 percent/0.9 percent).

We are WEE, We Enhance Efficiency

WEET DO-27 SR3100 Schottky Barrier Rectifiers

SR3100 is identical to SB3100
Schottky barrier rectifiers. Some factories take the English abbreviation at the beginning and the middle, and some take the English abbreviation at the beginning and the back. The electrical properties are not different.

Schottky diodes are low-power, high-current, ultra-high-speed semiconductor devices that have been available in recent years. The reverse recovery time is extremely short (can be as small as a few nanoseconds), the forward voltage drop is only about 0.4V, and the rectified current can reach several thousand amperes. These excellent characteristics are unmatched by fast recovery diodes.

Schottky diodes are named after their inventor, Dr. Schottky, short for Schottky Barrier Diode (abbreviated as SBD).
The SBD is not fabricated by the principle of forming a PN junction by contacting a P-type semiconductor with an N-type semiconductor, but by a metal-semiconductor junction principle formed by metal-to-semiconductor contact.
Therefore, SBD is also called a metal-semiconductor (contact) diode or a surface barrier diode, which is a hot carrier diode.

WEET DO-35 1N4148 Silicon Epitaxial Planar Switching Diode

1N4148 is a small high-speed switching diode with fast switching. It is widely used in single-pass isolation, communication, computer boards, TV circuits and industrial control circuits for circuits with high signal frequencies.
75V reverse withstand voltage and 150mA average forward current, very suitable for general rectification in general occasions.
The 4pF junction capacitance and 4nS reverse recovery time are sufficient for most applications.
Very easy to obtain, as well as a small signal high frequency diode that is inexpensive and versatile.

Confirm the parameters of SF18, current 1A, voltage 600V, voltage drop 1.7V, recovery time 35ns (nanoseconds) package DO-41, then we can use SF28 with larger current, SF38 instead of SF18.
Provided that other parameters are consistent except current, and the package is not limited.
If the package is to be selected the same, then it can only be packaged with a larger chip. Please see below for specific parameters.

SF28 current 2A, voltage 600V, voltage drop 1.7V, recovery time 35ns (nanoseconds) package DO-15

SF38 current 3A, voltage 600V, voltage drop 1.7V, recovery time 35ns (nanoseconds) package DO-27

Packing volume size order: DO-27 is larger than DO-15 is larger than DO-41, the larger the volume, the better the heat dissipation effect
