Thyristors - SCRs are a class of electronic components that are increasingly present in various applications today. In particular, a type of Thyristor-SCR, the TN805-600H, is increasingly being used across many applications. This article will discuss the TN805-600H in terms of its application field and working principle.

As for its application field, the TN805-600H is commonly used in the field of power regulation and electrical systems, such as power supplies, motors and current control. Specifically, the TN805-600H is useful in applications with high power and voltage requirements up to 600V and 60A respectively. Moreover, due to its low switching loss and its low turn-on and turn-off times, it is also suitable for ultra-fast current applications, such as aircraft instrumentation, industrial instrumentation and railway radio systems where rapid turn-on and turn-off of a high power current is often beneficial.

Aside from its application field, it is also important to understand the TN805-600H’s working principle in order to gain insight into its uses and advantages. To begin, the TN805-600H is a three-terminal Thyristor-SCR, or rather a silicon controlled rectifier. It is made of semiconductor material and is used to control electrical power based on the external applied voltages. Specifically, the TN805-600H consists of two layers: the main thyristor layer and the control gate layer. The main thyristor layer is formed from a junction of PN-type material with its anode on the positive end and its cathode on the negative end. The control gate layer is then placed onto the main thyristor layer, where the control signal is applied to the gate terminal. When the voltage across the anode and cathode is above the TN805-600H’s holding current, the Thyristor-SCR will switch to an on state allowing a current to flow from the anode to the cathode. In contrast, when the voltage across the anode and cathode drops below the TN805-600H’s current, the connection between the anode and cathode is broken, turning it off.

As a result of its high voltage and power requirements, the TN805-600H has become an increasingly popular solution for high power applications. Furthermore, its low load losses and the ability to rapidly turn-on and turn-off current makes it now an attractive option for power controls. As such, it is expected to continue to gain in popularity and be used in a variety of applications in the future.
