TVS - Thyristors

Thyristors are a class of semiconductor device with three or more terminals, two of which are anode and cathode. They are devices with a bi-directional electrical switch and are used in many applications. The thyristor can be triggered into the on state by a relatively small voltage, and with a wide variety of types and characteristics, thyristors are used in a multitude of applications. The MMT05B310T3G is a Programmable Switch Mode Thyristor (PTMT) which is widely used in switched-mode power supplies (SMPS), adjustable speed drives (ASDs) and DC motor control and power supplies.

MMT05B310T3G Application Field

The MMT05B310T3G is a programmable thyristor for high frequency switching operation. It is used in many different applications in order to control the power output, including SMPSs, adjustable speed drives, DC motor control and power supplies.The MMT05B310T3G is also used in power supplies for industrial automation systems, electronic ballasts, switching regulators and RF amplifiers. It is ideal for these applications because of its low forward voltage drop, ability to switch over a wide range of frequencies, and its extremely low on-state voltage.

MMT05B310T3G Working Principles

The working principle of the MMT05B310T3G is to use a small voltage to switch the thyristor on, and a gate current to switch it off. The small voltage is known as the gate trigger voltage, and the gate current is known as the gate current limit.When the voltage or current that exceeds the gate trigger voltage and current limit is applied to the gate of the thyristor, the device turns on. This causes the current to flow through the device. As the current flows, it causes a voltage drop across the device, thus providing the desired effect, which can be an output voltage, a controlled current, or a signal.When the gate current limit is reached, the device switches off automatically, thus providing protection for the circuit.The MMT05B310T3G has several advantages over traditional thyristors, such as its ability to provide extremely low forward voltage drops, improved surge protection and improved ESD capability. It is capable of operating over a wide range of frequencies, and can provide a fast switching time.

Conclusion

The MMT05B310T3G is a Programmable Thyristor (PTMT) which is widely used in many different applications, such as switched-mode power supplies, adjustable speed drives, DC motor control and power supplies. Its main advantages include its ability to provide extremely low voltage drops, improved surge protection and improved ESD capability. It is capable of operating over a wide range of frequencies, and can provide a fast switching time.
