It is also used in over-temperature protection or current limiting applications.

Working Principle

The BT134W-600,135 works by using a single gate voltage to activate multiple thyristors simultaneously. Essentially, it acts as a switch, allowing AC current to flow through the device and becomes open when the gate voltage is removed. This is possible due to the symmetrical gate characteristics of the BT134W-600,135.

In order to use the BT134W-600,135, it needs to be wired correctly. AC current flows into the device through the anode and cathode terminals and the gate voltage is applied to the gate terminal. When the voltage applied to the gate terminal exceeds a certain value, the BT134W-600,135 will start conducting. The current applied to the gate terminal can be used to control the amount of current flowing through the device.

Conclusion

In summary, the BT134W-600,135 is a type of TRIAC that is often used for a variety of AC controlling applications. Notable applications include controlling of AC motors and lamps, driving of high-voltage AC loads, and resistive and inductive AC circuits. The BT134W-600,135 works by using a single gate voltage to activate multiple thyristors simultaneously and can be used in applications that require a switch that can turn AC current on or off. To use the BT134W-600,135 correctly, it needs to be wired with the AC current flowing into the device through the anode and cathode terminals, and the gate voltage applied to the gate terminal.
