S8055MTP

Thyristors – SCRs are commonly used in power electronics applications and come in a variety of packages. The S8055MTP is one such thyristor, available in a through hole mounting package. It is an SCR with a trigger current in the range of 3 to 8 milliamp, and its maximum usable voltage ranges from 200 to 600 volts. It is widely used in military and industrial application as it is easy to install and highly reliable. Its power rating is 5 amps, with a peak current of 10 amps.

The S8055MTP is designed for use in high power applications like motor speed controllers, motor starters, and soft start motor controls. It is also used for power transformer protection, power supplies and snubbing. It provides over current, over voltage and over load protection for motor controls, sensing and switching for various power systems.

The most important feature of the S8055MTP is its ability to withstand high temperatures and high frequencies. It is suitable for medium to high power applications where high dynamic response time is required and is suitable for withstanding temperatures up to 150°C in industrial applications. The high peak current and voltage handling capability provide an added level of protection.

The S8055MTP’s working principle is based on the thyristor principle. A thyristor is a four-layer semiconductor device that acts as a switch when triggered. When a trigger current is applied to the thyristor, a self-sustaining current flow is created and the thyristor enters a conducting state. This sustained current flow continues until the trigger current is removed or the circuit is otherwise deactivated.

The S8055MTP has an additional protection feature which is called the ‘active locking’. This feature enables the thyristor to remain in a conducting state even after the trigger current is removed. This feature is essential in applications such as motor starters, to ensure that the motor does not over accelerate and damage itself.

In addition to its characteristics, the S8055MTP is also capable of withstanding high magnetic fields and high frequency noise. Its low thermal resistance, low capacitance and low dissipation coefficient add to its versatility. The S8055MTP is considered a reliable and trustworthy device for many power applications.

The S8055MTP is a reliable and versatile thyristor offering robust performance with high power capability and excellent heat dissipation under extreme conditions. With its wide range of operating voltage, current and frequency handling capacity, the S8055MTP is the ideal choice for high power applications. It is a dependable and long lasting device which can be relied on in industrial and commercial settings.
