BT138-800,127

A TRIAC is three terminal electronic device which is basically a controllable kind of switch and it is comprised of two SCRs, two gates and one common connection point. The BT138-800 and 127 family of TRIACs have a variety of application areas. The common structure of BT138-800 and 127 TRIACs enables them to be used for a variety of purposes, including as an amplifier for controlling current, voltage, and frequency.

BT138-800 and 127 TRIACs can be used as a sort of power switch. Using an appropriate voltage, the BT138-800 and 127 TRIACs can be used to turn on and off specific electrical currents. They are capable of producing DC and AC currents, depending on the control and application the user wishes to use. In a DC circuit, the TRIACs can be used to regulate the amount of current by changing the voltage level and the amount of resistance in an AC circuit, the TRIACs can be used to control the current and/or frequency.

Additionally, BT138-800 and 127 TRIACs can be used in a variety of other applications, such as switching AC loads, acquiring information from sensors, regulating the speed of motors, or controlling the speed of stepper motors. As the BT138-800 and 127 family of TRIACs are capable of reliably responding in a precise and consistent manner, they are also ideal for use in radio automation, security systems, relays, and analog modulation.

In terms of their working principle, the BT138-800 and 127 family of TRIACs are essentially switches that are triggered through the application of an appropriate voltage. When a voltage greater than the threshold voltage is applied to the gate terminal, the two junctions of the thyristor become forward-biased, allowing the flow of current to either gate. This will turn on the switch and activate the BT138-800 and 127 TRIACs.

The BT138-800 and 127 family of TRIACs is a versatile and reliable type of electronic device that can be used for a wide range of applications. Thanks to their precision and consistency, they are ideal for use in many fields, such as in motor regulation, radio automation, sensing, and analog modulation. Moreover, their working principle is relatively straightforward; the application of a voltage greater than the threshold voltage to the gate terminal will turn on the switch and activate the TRIAC.
