Thyristors - TRIACs are a type of semiconductor device consisting of three terminals which are semiconductors regions. In general, the BT138X-800E 127 application fields and working principle is one of the most commonly used in the triac devices, and is widely used in many applications.

The BT138X-800E 127 triac is a general purpose, low power, sensitive gate, three quadrant, turn-off triac device. It is suitable for resistive AC flourescent lighting ballast applications, static switch, ac static relays, small motor control, etc., and it also is capable of controlling higher powers than the other triacs devices.

The BT138X-800E 127 has three distinct terminals, the anode, the gate and the cathode, which can be considered as three-terminal controllable switches. It works on the comparative principle, which states that the anode is always more positive than the cathode and the anode detects any potential applied to the gate. If a potential is detected, it then conducts current between the terminals. The gate can also be used to control the current flow with an externally applied voltage to the gate. Once the gate is triggered, it will remain on till either the supply voltage or the load current drops to zero.

Moreover, the BT138X-800E 127 has a very low on-state voltage drop, which is beneficial for power savings. Since it has a gate-controlled design, it does not need a speed up capacitor for the turn off operation. Additionally, the device is RoHS/REACH compliant, which makes it more user-friendly and reduces waste of materials.

The BT138X-800E 127 offers a number of advantages over other typical triac devices, which make it more applicable for various applications. Firstly, it has a very low on-state voltage drop which results in higher efficiency and power saving. Secondly, it has a sensitive gate, which allows it to trigger with a lower gate voltage compared to other triac devices. Thirdly, it offers a three-quadrant operation, which means it can work under both forward and reverse conduction, and can be used in a variety of applications such as AC motor control. And lastly, as it is RoHS/REACH compliant, it can be used without worrying about its waste materials.

Overall, the BT138X-800E 127 triac are very versatile devices with a wide range of applications. It offers an efficient and power saving design, a sensitive gate, a three-quadrant operation, and a RoHS/REACH compliant design. These features make it a superior choice for many applications in comparison to other triac devices. It is ideal for applications such as AC motor control, resistive AC flourescent lighting ballast applications, static switch, AC static relays, and small motor control.
