1. Schottky Barrier Diode
Schottky Barrier Diode is a lowpower and ultrahighspeed semiconductor device , which is widely used in switching power supply , frequency converters , drivers and other circuits , as a highfrequency , lowvoltage and highcurrent rectifier diode and protection diode , or as a rectifier diode and a smallsignal detector diode in microwave communication and other circuits.
2. Rectifier Diode
Rectifier Diode is a device that converts alternating current into direct current, which can be used for power supply devices and detecting radio signals. Simply put, it is a device that converts alternating current (AC) into direct current (DC). It has two main functions: first, it changes alternating current (AC) into direct current (DC) and supplies it to the load or inverter after filtering; Second, provide charging voltage for the battery. Therefore, it also acts as a charger.
3. Bridge Diode
Bridge Diode is a part of power supply, which can convert alternating current into direct current. The main application of bridge rectifier is to convert AC power supply into DC power supply. Because the power supply of the power company is AC, unless batteries are used, rectifiers are needed inside the power supply of all electronic equipment.
4. TVS Diode
Transient Voltage Suppressor (TVS) is a diode with high efficiency to protect components. When the two poles of TVS are impacted by reverse transient high energy, the high impedance between the two poles can be changed into low impedance, and the surge power up to several kilowatts can be absorbed, so that the voltage between the two poles can be clamped at a predetermined value, effectively protecting the precision components in electronic circuits from being damaged by various surge pulses.
Because it has the advantages of fast response, large transient power, low leakage current, small breakdown voltage deviation, easy control of clamping voltage, no damage limit and small size, it has been widely used in computer systems, communication equipment, AC/DC power supply, automobiles, electronic ballasts, household appliances, instruments (watt-hour meters) and other fields.
5. ESD Diode
Electrostatic discharge protection devices are anti-static protection elements, which are used to protect sensitive circuits in electronic equipment from the influence of ESD (electrostatic discharge), and their functions are to transfer ESD stress from sensitive elements, so that current can flow through the protection elements instead of the sensitive elements, while maintaining low voltage on the sensitive elements. The ESD electrostatic protector should also have the characteristics of low leakage and low capacitance, which will not reduce the circuit function; It will not damage the high-speed signal, and the function of the protection element will not decrease under the action of multiple stresses. It is mainly used for ESD protection of various communication interfaces, such as USB and HDMI.
6. Small Signal Diode
Small Signal Diode, a kind of Schottky diode, is a low-power and ultra-high-speed semiconductor device, which is widely used in switching power supply, frequency converter, driver and other circuits, or as a small signal detection diode in microwave communication and other circuits.
7. Zener Diode
Zener Diode is a diode with the function of stabilizing voltage, which takes advantage of the reverse breakdown state of PN junction, and its current can change in a large range while its voltage is basically unchanged. The zener diode is classified according to the breakdown voltage. Because of this characteristic, the zener diode is mainly used as a regulator or a voltage reference element. The zener diode can also be connected in series for higher voltage, and a higher stable voltage can be obtained by connecting in series.
8. MOSFET
Metal oxide transistor field effect transistor (MOSFET) can be widely used in analog circuits and digital circuits. MOSFET can be divided into "N-type" and "P-type" according to the polarity of its working carriers. Due to the gradual improvement of the performance of MOSFET components, in addition to the traditional application in digital signal processing such as microprocessors and microcontrollers, there are more and more integrated circuits used in analog signal processing.
