T10A140E

TVS (Thyristors) are solid-state semiconductor devices commonly used in applications including motor control and protection circuits. They are typically used in applications requiring a high current capacity, such as switching power supplies. The T10A140E is a popular thyristor used in these types of applications.

The T10A140E is a unidirectional thyristor with a nominal blocking voltage of 140V. It has an on-state current of 10A and an off-state leakage current of 1mA. The on-state voltage drop is 0.4V. It comes in a TO-220 power package and can be mounted on a heat sink to dissipate heat.

The T10A140E can be used in a range of applications. These include motor, fan, solenoid, heater and other control and overload protection circuits. It can also be used in automated process control systems to provide reliable switching. It can be used in switching power supplies due to its high current capacity and low on-state voltage drop.

The working principle of the T10A140E is relatively simple. When a positive voltage (referred to as the “gate” voltage) is applied to the thyristor’s gate, it turns on. This allows current to flow through the thyristor. When the gate voltage is removed, the thyristor turns off and the current flow stops. The thyristor can also be turned off by reversing the current through it. This is known as “breakover”.

In conclusion, the T10A140E is a unidirectional thyristor that can be used for motor, fan, solenoid, and heater control and protection circuits. Its on-state voltage drop is 0.4V and it has a blocking voltage of 140V. Its working principle is based on the application of a positive voltage to the gate in order to turn it on, and the removal of the gate voltage, or the reversal of the current, to turn it off.
