亚博提款要一倍流水the global fet market size in 2019 is about 8 billion us dollars (55 billion yuan). as the sino-us trade war has raised tariffs, the price of imported fets has risen, and the us ban on huawei has prompted the country to accelerate research and development and investment in this area. it is expected that the localization rate will continue to increase in the future. the well-known domestic fet brand shenzhen tongshunda technology plans to use this market situation to increase research and development, and will provide more domestically produced replacement devices for the market.
let's talk about the difference between a triode, a three-terminal regulator, and a fet:
field effect transistor, referred to as field effect transistor. there are two main types and metals - oxide semiconductor fets. conductors are involved in majority conduction, also known as unipolar transistors.
亚博提款要一倍流水it belongs to a voltage controlled semiconductor device. it has high input resistance (107~1015ω), low noise, low power consumption, large dynamic range, easy integration, no secondary breakdown, wide safe working area, etc. it has become a powerful bipolar transistor and power transistor. competitor.
the triode, the full name should be a semiconductor triode, also known as a bipolar transistor, a crystal triode, is a semiconductor device that controls current. its function is to amplify the weak signal into an electrical signal with a large amplitude value, and also as a contactless switch. . the crystal triode is one of the basic components of semiconductors and has a current amplification function, which is the core component of electronic circuits.
亚博提款要一倍流水the triode is made up of two closely spaced pn junctions on a semiconductor substrate. the two pn junctions divide the monolithic semiconductor into three parts, the middle part is the base area, and the two sides are the emitter area and the collector area, and the arrangement is pnp. and npn two.
a three-terminal zener diode is a semiconductor device that has a very high resistance until a critical reverse breakdown voltage. when the voltage regulator is in reverse breakdown, within a certain current range (or within a certain power loss range), the terminal voltage is almost constant, showing a voltage regulation characteristic, and thus is widely used in a regulated power supply and a limiting circuit. among them.
