Thyristors - TRIACs play an important role in developing modern electrical systems, allowing the control of bidirectional current using a solid state semiconductor device. The 2N6073BG is high voltage TRIAC, specifically engineered for applications in power switching, radio and industrial control equipment. In this article, the application field and working principle of the 2N6073BG will be discussed.

Application Field

The 2N6073BG is a high power rugged TRIAC with a maximum current rating of 8A and maximum gate trigger current of 50mA. It is designed for use in applications such as motor speed control, lamp dimming, solid-state relays, and other AC power switching applications. The device is rated for an operating junction temperature range of -65C to +175C, making it suitable for use in a wide range of industrial, commercial, and consumer applications. The high voltage rating of 600V also makes it well-suited for high-power applications.

The 2N6073BG is a conducting device when gate voltage exceeds the gate trigger voltage of 2.5V and the device is turned on. The device can be used either in AC switching applications or in DC switching applications, depending upon the requirements of the application. For AC applications, the device is placed in series with an AC power source and the gate voltage is applied when the device needs to be turned on or off. For DC applications, the device is placed in series with a DC power source and the gate voltage is applied when the device needs to be turned on or off.

Working Principle

The 2N6073BG is a four-layer p-n-p-n structure with a gate electrode. When a positive gate voltage is applied, a layer of holes and electrons are created which cancels out the depletion charge in the base region and allows conduction to occur between the Anode and the Cathode. The device can also be turned off by reducing the gate voltage below the threshold gate voltage. The gate current must be kept to a minimum to avoid device damage due to excessive heating.

The 2N6073BG is capable of high-speed, high-power switching due to its superior construction and materials. The device is capable of controlling both AC and DC loads, making it well-suited for applications such as lighting control, temperature control, and motor speed control. The device also features integrated, temperature-compensated gate-triggering circuitry, allowing for accurate turn-on and turn-off signaling.

In conclusion, the 2N6073BG is a high power TRIAC device that is suitable for a variety of AC and DC switching applications. Its rugged construction and wide temperature range make it suitable for a variety of industrial and commercial applications. The device\'s integrated, temperature-compensated gate-triggering circuitry make it an ideal choice for controlling both AC and DC loads.
