Abstract

The invention relates to the technical field of electronic components, in particular to a photosensitive silicon controlled rectifier integrated with a transverse transistor. The photosensitive silicon controlled rectifier integrated with the transverse transistor comprises a silicon controlled rectifier body, a pin body and a connecting plate, the connecting plate is installed at the top of the silicon controlled rectifier body, the pin body is installed at the bottom of the silicon controlled rectifier body, a round hole is formed in the surface of the connecting plate in a penetrating mode,and a protection frame is arranged on the surface of the silicon controlled rectifier body. According to the invention, the protection frame, a heat conduction layer, a fixing plate, support columns,a bottom plate, the pin body, a impact-resistant coating layer, a damping layer and a fixing mechanism are arranged; therefore, the silicon controlled rectifier has an additional supporting structure, has impact resistance protection, is not easy to damage in the impact process, and solves the problems that some existing photosensitive silicon controlled rectifiers are lack of support structures,and are easy to topple over when being subjected to external impact, so that pins are bent and even damaged, the impact resistance is poor, and the silicon controlled rectifiers are easy to damage when being subjected to impact force.

Description

technical field [0001] The invention relates to the technical field of electronic components, in particular to a photosensitive thyristor integrating lateral transistors. Background technique [0002] A transistor is a solid semiconductor device, usually including diodes, triodes, field effect transistors, thyristors, etc., sometimes specifically bipolar devices. Transistors have multiple functions such as detection, rectification, amplification, switching, voltage stabilization, and signal modulation. A transistor acts as a variable current switch, capable of controlling the output current based on the input voltage. Unlike ordinary mechanical switches, transistors use electrical signals to control their own opening and closing, so the switching speed can be very fast. SCR is abbreviated as SCR, which is a high-power electrical component, also known as a thyristor. It has the advantages of small size, high efficiency and long life. In the automatic control system, it can ...

Problems solved by technology

[0004] The object of the present invention is to provide a photosensitive silicon controlled rectifier integrated with lateral transistors, which has an additional supporting structure, and has impact protection, and makes itself not easy to be damaged during the impact process, which solves the problem of some existing photosensitive silicon controlled silicon controlled rectifiers. Lack of support structure, when subjected to an external impact, it is easy to cause the thyristor to fall, which in turn leads to bending or even damage to the pins, and the impact resistance is poor, and the thyristor itself is easily damaged when it is impacted
