According to the efficient surface-mounted triode of the invention, the sealing waterproof assembly is adopted, the connecting positions of the pins and the packaging outer shell can be conveniently prevented from being affected with damp and aged; and the heat dissipation assembly is adopted, sothat the efficient heat dissipation of the surface-mounted triode is facilitated.

Description

technical field [0001] The invention relates to the technical field of patch triodes, in particular to a high-efficiency patch triode with a good heat dissipation structure. Background technique [0002] SMD triode belongs to an electronic component. The basic function of SMD triode is to amplify. It can amplify weak electrical signals to a certain intensity. An important parameter of the triode is the current amplification factor β. When a small current is applied to the base of the triode, a current that is β times the injected current can be obtained on the collector, that is, the collector current. And a small change in the base current can cause a large change in the collector current, which is the amplification effect of the SMD transistor. [0003] The existing patch triode has a relatively simple structure, does not have a good heat dissipation structure, and is easily damaged by high temperature inside, so it needs to be replaced frequently, which increases the co...

Problems solved by technology

[0004] The purpose of the present invention is to provide a high-efficiency patch triode with a good heat dissipation structure to solve the problem that the existing patch triode proposed in the above background technology has a relatively simple structure, does not have a good heat dissipation structure, and is easily damaged by high temperature inside. Therefore, it needs to be replaced frequently, which increases the cost of use, and the connection between the pin and the package shell is prone to moisture, which leads to erosion and aging, which affects the service life, and the structural strength and wear resistance are poor, and it is easy to be damaged or cracked.
