Thyristors are a type of semiconductor current switch. Triacs, also known as bidirectional thyristors (BTTs), are a specific type of thyristor that is widely used in many types of electronic devices. The BT137S-800G,118 is a type of Triac from STMicroelectronics.

In general, Triacs are constructed out of four layers of semiconductors. These layers are called the anode, cathode, gate, and finder electrodes. The anode and cathode electrodes control the current flow direction, and the gate electrode is responsible for turning on or off the Triac’s switching action. The finder electrode is responsible for blocking leakage currents.

The BT137S-800G,118 is an 800V triac. It has a maximum current of 119A, and a maximum on state current of 800mA. It is suitable for use in a variety of applications, such as motor control, power control, and home appliances. It has several features that make it suitable for these applications, such as a low on-state voltage drop and a short turn-on time.

The BT137S-800G,118 is a dv/dt turn-on device, meaning that it will turn on when the voltage across it increases rapidly. It is designed to turn on at a maximum of 1A/us which makes it suitable for high speed applications. It also has an integrated static dv/dt and current limiting features for even better protection.

The proper working of the BT137S-800G,118 depends on the gate to provide a triggering pulse. This pulse must have the appropriate voltage, timing, and duration to turn the Triac on. When the gate receives a positive pulse, the Triac will turn on and will remain on until the current drops to zero. At that point, the gate pulse must be reversed to turn the Triac off. This makes the BT137S-800G,118 ideal for AC applications.

The BT137S-800G,118 is designed for a wide range of applications, including home appliances and industrial motor controllers. It is well-suited for external triggering as well as for internal triggering applications. Its low on-state voltage drop, fast switch-on time, and integrated static dv/dt and current limiting features make it a great choice for many applications.
