Shenzhen Sacco Micro Semiconductor Co., Ltd.

2021This year is an opportunity but also a crisis for the semiconductor industry. Due to the U.S. sanctions against China, there is a shortage of chips in the semiconductor industry this year. There was a "core shortage" for a time, which triggered 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 materials for electronic manufacturers, there will be a sharp decline in sales. In this situation of large market fluctuations, Sacco Micro SemiconductorSLKORThe ability to remain independent is due to the long-term vision of Mr. Song Shiqiang, the general manager of Sacco Micro, and Mr. Zheng Zhangbiao, the vice president. As the old saying goes, "Be born in sorrow and die in happiness." In the rush to buy, we did not limit ourselves to immediate interests, but made decisions based on the long-term, which made Sacco Micro SemiconductorSLKORAfter the rush to buy, stable sales can still be maintained.

Sacco Micro SemiconductorSLKORBeing able to maintain stable sales is inseparable from Sacco Micro's product quality and product diversification. Sacco Micro SemiconductorSLKORThere are more than ten product series:

one,Zener diode

Sacco Micro SemiconductorSLKORZener diodes (also known as Zener diodes) are mainly used in surge protection, TV overvoltage protection, arc suppression, and series voltage stabilizing circuits. They are widely used in relays, TVs, and industrial high-power electromagnetic control circuits.

When the voltage regulator tube 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 operating current, the smaller the dynamic resistance, and the better the voltage stabilization performance. When the reverse voltage is greater than the breakdown voltage, the current flowing through the diode increases sharply, but the voltage across it remains basically unchanged. This can be used to stabilize the voltage.

Schottky diode base barrier height ratioPNThe junction barrier height is low, and the forward conduction threshold voltage and forward voltage drop are also lower thanPNJunction diode low. Schottky diode is a majority carrier conducting device and does not have problems such as minority carrier lifetime and reverse recovery. The reverse recovery time of the Schottky diode is just the charging and discharging time of the Schottky barrier capacitor, which is completely different fromPNJunction diode reverse recovery time. Because the reverse recovery charge is small, Schottky diodes switch extremely quickly and have minimal switching losses, making them particularly suitable for high-frequency applications.

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

Switching diodes have the characteristics of fast switching speed, small size, long life and high reliability. They are widely used in switching circuits, detection circuits, high-frequency and pulse rectification circuits and automatic control circuits of electronic equipment.

A diode is an electronic device with two electrodes that allows current to flow in only one direction. Many uses are for its rectifying function, and varactor diodes are used as electronic adjustable capacitors. The current directionality possessed by most diodes is called“rectifier”Function. The most common function of a diode is to only allow current to pass in one direction, which is called forward bias, and to block it in the reverse direction, which is called reverse bias.

The Darlington tube is two triodes connected together, and the polarity only recognizes the front triode. The specific connection method is as follows, taking two triodes of the same polarity as an example. The collector of the front triode is connected to the collector of the rear triode, and the emitter of the front triode is connected to the base of the rear triode. The power of the front triode is generally smaller than that of the rear triode. The base of the front triode is the base of the Darlington tube, and the emitter of the rear triode is the emitter of the Darlington tube. The usage is the same as that of the triode. The amplification factor is the product of the magnification of the two triodes. It is widely used in high-power switching circuits, motor speed regulation, inverter circuits, driving small relays, etc.
