When it comes to the rectification of alternating current (AC) through the use of a diode, two of the most common applications are the Reverse-Blocking Triode Thyristor (RKT) and the Rectifier Three-Phase Diode. Both of these technologies share the same purpose: to transform AC to DC, but they do so in very different ways. Both of these technologies are classified under the same category: Diodes - Rectifiers - Single, but understanding the differences between them is important for making the most optimal decisions for an application.

The RKT is an inversion-protected gate-controlled thyristor with a reverse-blocking triode (RBT). It is a silicon-controlled rectifier (SCR) and it functions as such; when the control gate receives a positive signal, the thyristor opens and allows current to flow. The RBT will also block reverse current. Because of this ability, it is often used in rectifier circuits, protective circuits, and other applications that require overcurrent protection.

The RS3G R7G, on the other hand, is a three-phase rectifier diode. It is primarily characterized by its three separate connections, which are designed such that input AC current will flow through and be rectified by diodes in parallel. As with all rectifiers, the RS3G R7G converts alternating current, to direct current and is popular for applications such as motor drives, UPS, and inverters.

The main difference between these technologies is their working principle. With RBT, the thyristor is opened and closed in response to a signal from the control gate; with the RS3G R7G, the three diodes are connected in a special arrangement to allow current to flow.

In terms of their application field, the RBT is mainly used in rectifier circuits, protective circuits, and other applications requiring overcurrent protection, while the RS3G R7G is mainly used in motor drives, Uninterruptible Power Supplies (UPSs), and inverters. The important thing to note is that the RBT is better at blocking reverse current, whereas the RS3G R7G is better at providing direct current.

In summary, understanding the difference between RBT and RS3G R7G is important for making the most optimal decisions for an application. Although classified under the same category: Diodes - Rectifiers - Single, their working principle and the application field differ from each other. The RBT is mainly used in rectifier circuits, protective circuits and other applications requiring overcurrent protection, while the RS3G R7G is mainly used in motor drives, UPS and inverters.
