Technical description: 5SHX1445H0002 3BHL000387P0101 ABB thyristor semiconductor device

The 5SHX1445H0002 3BHL000387P0101 Thyristor is a semiconductor device, also known as Silicon Controlled Rectifier (SCR). It has controllable on-off and cutoff characteristics, which can realize power control and regulation.

The working principle of the 5SHX1445H0002 3BHL000387P0101 thyristor is based on the PN junction of the semiconductor. When a forward voltage is applied to the PN junction, the current can flow through the PN junction to make the thyristor open. When the reverse voltage is applied to the PN junction, the current cannot flow through the PN junction and the thyristor is shut off.

The on and off state of the 5SHX1445H0002 3BHL000387P0101 thyristor can be achieved by controlling voltage or current. Applying a small control voltage or current to the control end of the thyristor can control the on and off of the thyristor, so as to realize the control and regulation of the power.

5SHX1445H0002 3BHL000387P0101 thyristors are widely used in power electronics, such as AC voltage regulation, DC voltage regulation, motor control, lighting control and so on. It has the advantages of simple control, high reliability and high power density, and is one of the important control devices in power electronics technology.

There are many kinds of circuits based on thyristors, the most common of which is SCR Rectifier Circuit (SCR Rectifier Circuit).

Thyristor rectifier circuit is a kind of circuit which realizes the conversion from AC to DC by using the controllable conduction characteristic of thyristor. It can realize the functions of regulating voltage, rectifying and inverting alternating current. In addition to the thyristor rectifier Circuit, there are SCR Dimming Circuit (SCR Dimming Circuit), SCR Trigger circuit (SCR trigger circuit) and other thyristor as the core of the circuit. These circuits make use of the controllable characteristics of thyristors to realize the control and regulation of power.
