Since 2018, the price hike of semiconductors has been rising from silicon wafers, passive components, MOSFETs to resistors, aluminum electrolytic capacitors, and now diodes continue to rise in price, and the price increase far exceeds expectations. In 2019, after the price surge of components last year subsided and even the price began to fall, it also ushered in a wave of diode price increases...

According to media reports, diodes price of international IDM manufacturers continued to rise in the first quarter of 2019. Manufacturers such as ON Semiconductor and Vishay are almost all rising.

In addition to the price increase of diodes, the delivery of bridge rectifiers, schottky diodes, transient voltage suppression, rectifiers, switching diodes, etc. has been extended to 16-40 weeks, the longest even 52 weeks.

At present, the demand for new energy electric vehicles and vehicle electronics in the market has risen sharply. For example, the advanced driver assistance system integrates blind spot detection, lane departure warning and parking assistance, and the number of diodes is several times higher than in the past.

It’s time to contact Kingtronics for various cost-effective solutions. Our L/T and price are even better than before, your order schedules will be easily to be fulfilled.

In second half of 2018, we met tough challenge with SOT-23 package diodes and transistors raw material supplies.
The prices increased and lead time was much longer than ever before.

Fortunately, SOT-23 package support is resumed normal in late Jan, 2019.
We even have chance to offer better prices than the original ones for some values with big quantity now.
