8T210B35BA Application Field and Working Principle

The 8T210B35BA is a high power sharing vehicle-mounted semiconductor switch designed for use in railway communications, industrial control, military and other harsh environments. This switch features fast on/off switching, up to 25A current output, and a share voltage capacity of up to 60V.

The 8T210B35BA\'s main use is in applications that require a high current switching capability through a wide voltage range, such as railway signal control systems. This type of switch can be used to control both power and signal flow within a closed loop system. This can be done in a single switch, as opposed to multiple smaller switches, with both current and voltage control.

The 8T210B35BA has a compact design, which helps to reduce its size and minimize the cost of production. It is also built with military-grade components like aluminum casing, permanent wave solder, and high copper contact points. This makes it especially suitable for use in harsh environments, where high reliability and endurance are important.

The switching principle of the 8T210B35BA switch is based on a semiconductor-controlled pressure sensitive mechanism. It has two different contact points which originate from separate thermal pressure-sensitive resistors. When the voltage is applied to the top contact point, it will cause the thermal pressure-sensitive resistor to increase in temperature, forcing the contact points to close. The current flow will then be switched on or off, depending on the setting of the thermal pressure-sensitive resistor.

The 8T210B35BA is designed to be used with a special controller, such as a power source or an interface board. These controllers can be programmed to adjust the switch\'s output current and voltage settings. This allows for greater flexibility and control in the application.

In summary, the 8T210B35BA switch is a versatile, high current-sharing device that can be used in a wide variety of applications where a reliable and powerful switching option is needed. Its compact design and military-grade components make it especially suitable for use in harsh environments. It has two contact points that control the current and voltage output, allowing for greater flexibility and control over the application.
