MMT08B350T3G Circuit Protection

Thyristor, also known as silicone control rectifier (SCR), is a kind of solid-state device. It is mainly composed of four layers of materials with the same conductive type in two opposite directions. The main element of thyristor mainly consists of gate, anode, cathode and PNPN structure layers. It is widely used in various areas because of its features such as delicate control, fast response, small heat conduction coefficient, large electric capacity and high accuracy.

MMT08B350T3G is a kind of Thyristor, with reverse blocking capability of up to 300 V, 1500 W & 10 mA in varying temperatures, and average on-state current IT(AV) of up to 8A (Up to 4A in a steady state). It is usually chosen for applications that need higher voltage, such as solar-generators, electric power tools, household appliances and lighting circuits.

The working principle of MMT08B350T3G Thyristor can be divided into three stages: bi-stable state, turn-on state and turn-off state. When the anode is connected to a certain voltage, and the current of the anode soon passes through the gate current, the thyristor enters a bi-stable state. In this state, the thyristor can either maintain the blocking state or the conducting state according to the magnitude of the anode current. When the gate current is larger than a certain value and the anode current tends to keep increasing, the thyristor enters the conduction state and can remain in the conducting state until the anode current is cancelled. After the anode current is cancelled, the thyristor enters the blocking state and remains in this state until the anode current exceeds a certain value again.

The features of MMT08B350T3G in practice are: high-speed switch control, wide range of on-state current regulation, low forward voltage drop, and low heat conduction coefficient, which make it an ideal choice in various applications. MMT08B350T3G Thyristor is usually used as safety devices preventing over-current and over-voltage parts in various systems, or used in the rectifier of AC direct current electricity. In the switching field, it is mainly used as a switch, and in the charging and discharging field, it is used for quick charge and discharge.

Because Thyristor has many advantages compared to other devices, it is widely used in various electrical engineering fields, such as industrial, residential and commercial applications. In summary, MMT08B350T3G Thyristor is characterized by its high speed switch control, low forward voltage drop, and low heat conduction coefficient, which make it an excellent choice in different application fields.
