Shenzhen sacaowei Semiconductor Co., Ltd(www.slkormicro. com)In recent years, it has developed more and more rapidly. It has become a well-known brand instead of domestic power devices, serving more and more customers, and its products are exported to home and abroad. Sacco micro semiconductorSLKOROur technology comes from Busan, South Korea. Under the leadership of Mr. Song Shiqiang, general manager“slkor”After years of development in Greater China, brands and products have realized the transformation from design to designIPTo the localization of key links such as wafer flow and packaging test sales. Sarkozy microSLKORWith strict control over quality, the product quality has been widely recognized by customers at home and abroad, and the sales volume of products at home and abroad has doubled compared with last year.



Shenzhen sacaowei Semiconductor Co., Ltd


two thousand and twenty-oneIt was an opportunity but also a crisis for the semiconductor industry in. Due to the sanctions imposed by the United States on China, there was a shortage of chips in the semiconductor industry this year, which once led to a "core shortage", which led to a large number of purchases by various electronic product manufacturers. This is an opportunity for the semiconductor industry, but opportunities and risks coexist. With the saturation of electronic manufacturers' materials, Ushered in a substantial decline in sales. In this case of large market fluctuations, Sacco micro semiconductorSLKORIt is thanks to the long-term vision of Mr. Song Shiqiang, general manager of Sacco micro, and Mr. Zheng Zhangbiao, deputy general manager. As the old saying goes, "born of hardship and died of happiness", in the rush buying tide, Sacco micro semiconductor is not limited to immediate interests, but makes decisions in the long runSLKORAfter the rush buying tide, it can still maintain stable sales.




Sacco micro semiconductorSLKORThe ability to maintain stable sales volume is inseparable from the quality and product diversification of Sarkozy micro semiconductorSLKORThere are more than ten product lines:

When the voltage regulator is connected in reverse, when the reverse voltage is less than the breakdown voltage, the reverse current is very small and the dynamic resistance is very large. Generally, the larger the working current is, the smaller the dynamic resistance is, and the better the voltage stabilizing performance is. When the reverse voltage is greater than the breakdown voltage, the current flowing through the diode increases sharply, but the voltage at both ends is basically unchanged. This can be used to stabilize voltage.

The time of switching diode from off (high resistance state) to on (low resistance state) is called on time; The time from conduction to deadline is called reverse recovery time; The sum of the two times is called the switching time. Generally, the reverse recovery time is greater than the on time, so only the reverse recovery time is given in the service parameters of the switching diode. The switching speed of switching diodes is quite fast. For example, the reverse recovery time of silicon switching diodes is only a few nanoseconds, and even germanium switching diodes are only a few hundred nanoseconds.

The Darlington transistor is two triodes connected together, and the polarity only recognizes the front triode. The specific connection method is as follows. Take two triodes with the same polarity as an example. The front triode collector is connected with the rear triode collector, and the front triode emitter is connected with the rear triode base. The power of the front triode is generally smaller than that of the rear triode. The front triode base is the Darlington base, and the rear triode emitter is the Darlington emitter, The usage is the same as that of a triode.
