T500047004AQ

Thyristors - SCRs are semiconductors with a control terminal and three electrical terminals. T500047004AQ is a thyristor with a control terminal and three electrical terminals, so it falls into the Thyristors - SCRs category. This specific thyristor is an ultra-fast Triggered SCRs with 4kV blocking voltage, current ratings up to 1.8A, and a maximum trigger voltage of 200V. This thyristor is particularly suitable for use in circuits demanding high speed trigger and surge current capacity.

The main application field by far is power electronics, where thyristors can be used as switches and protectors to convert direct current (DC) to alternating current (AC). This is usually referred to as AC power control, as the thyristors control the current, voltage and frequency of the AC waveform. Thyristors are a possible solution for controlling very large power for industrial applications, and for switching power supplies.

When it comes to the working principle of the T500047004AQ, it is based on the fact that when a positive voltage is applied to the Gate electrode and a positive voltage is applied to anode terminal, a current flow between the cathode and anode begins, and the thyristor remains in an ON condition until the gate potential is reduced below a certain value (the Holding current). The main parameter that defines the behavior of thyristors is its Trigger current, which is the current passing through the Gate electrode at which the thyristor switches from its OFF state to ON (blocking) state. The trigger current determines the speed of the thyristor\'s switching, and the T500047004AQ has an ultra-fast trigger current, allowing it to respond quickly to changes in its Gate voltage.

Overall, the T500047004AQ is an ultra-fast Triggered SCRs with 4kV blocking voltage, current ratings up to 1.8A and a maximum trigger voltage of 200V. It is best used for high speed trigger and surge current capacity circuits, most commonly for power electronics applications where it can control current, voltage and frequency of the AC waveform. The working principle is based on the trigger current and its switching speed.
