TSMBJ0309C-130

TVS - Thyristors

The simplicity and robustness of thyristors have made them a popular choice for power switching applications in the electricity sector. Today, new technologies are emerging that allow even faster switching and better efficiency when compared to their predecessors (such as IGBTs).

One such device is the TSMBJ0309C-130 thyristor. This device features a reverse blocking voltage of up to 1300V, a forward surge current of up to 30A, and a maximum gate forward current of 2.2mA. In addition, this device has an on-state voltage drop as low as 1.5V and an on-state resistance of only 0.25Ω.

Due to its high-voltage reverse-blocking capability and solid-state reliability, the TSMBJ0309C-130 is a popular choice for a variety of applications, such as DC-to-AC conversion, speed control in motors, welding inverters, and other power switching applications.

The working principle of this device is simple yet effective. Basically, the device utilizes a thyristor design in which three terminals are connected to the gate, cathode, and anode, respectively. When a certain amount of current is applied to the gate terminal, this charge is passed through the gate to the anode and cathode, creating a forward current flow between the two terminals. This forward current flow is a result of the electric field created by the difference in voltages between the two terminals (also known as the PN-junction).

When the gate current is reversed (or removed entirely), the forward current flow is also stopped due to the reverse voltage drop between the two terminals. This is known as reverse breakdown, and it is one of the primary advantages of using a thyristor over other power switching components. In addition, the low on-state voltage drop and low on-state resistance of the TSMBJ0309C-130 make it suitable for a myriad of applications.

In conclusion, the TSMBJ0309C-130 thyristor is a reliable and cost-effective solution for power switching applications. Its reverse blocking voltage of up to 1300V, forward surge current of up to 30A, and low on-state voltage drop and on-state resistance make it suitable for a wide range of applications including DC-to-AC conversion, speed control in motors, welding inverters, and other power switching applications. The device utilizes a thyristor design to allow for a forward current flow between the two terminals when a certain amount of current is applied to the gate terminal, and the reverse breakdown feature makes it more efficient than other types of power switching components.
