Thyristors - TRIACs

A thyristor is an electronics switch, made up of a p-type and an n-type semiconductor region that when triggered, acts like a switch, controlling the current passing through it. When these two regions are brought together, a potential barrier is created, making it difficult for a current to flow across. By applying a certain gate voltage however, this potential barrier can be lowered, allowing current to flow.

A TRIAC is the most commonly used type of thyristor, and consists of two p-n regions that are connected together. It provides bidirectional current flow, meaning currents can flow both directions across it, meaning it can act as two switches in one.

The BT139-600,127 application field and working principle is one of the most common and widely used types of TRIACs. It is rated for an 800 volt maximum and a 0.6 amp mount, and is especially suited to household and small industrial uses where the current and voltage requirements are of a reasonable level. The BT139-600,127 is a three terminal device which can be used as a switch to control either AC or DC current. It is controlled by connecting a gate to the control terminal of the device and providing sufficient voltage to switch it on or off. When the gate receives a voltage higher than the threshold specified by the manufacturer, it switches on and provides a current path between the main AC terminals. When the gate voltage is taken back to a lower value, the current path is shut off.

The BT139-600,127 is widely used for home automation, lighting and other consumer electronic applications. It is also used for many industrial applications such as industrial motor control, heating controls and control panels. The device is especially suited to applications where the current and voltage ratings of a standard TRIAC device would be too low.

The BT139-600,127 is a cost effective solution for controlling AC and DC loads, and is easy to use. The device is essentially a switch, so when the voltage specified in the data sheet is applied to the control terminal, it switches on and current can flow through it. The device can then be taken back to the off state by taking the voltage down again. This makes the device ideal for applications where simple on/off control is required.

In summary, the BT139-600,127 is a three terminal device and is the most commonly used type of TRIAC. It provides bidirectional current flow, meaning it can act as two switches in one, and is rated for a 800 volt maximum and a 0.6 amp mount. It is widely used for home automation, lighting and other consumer electronic applications and is also used in a variety of industrial applications. The BT139-600,127 is a cost effective solution for controlling AC and DC loads, and is easy to use, making it an ideal choice for applications where simple on/off control is required.
