Thyristors - SCRs are a type of circuit component that can control the flow of electrical energy by acting as either an on/off switch or a regulator. A TN805-600B-TR is one type of SCR specifically designed for power control and is primarily used for switching high voltage and current loads. What sets it apart from other similar components is its ability to handle high currents and long conduction time. By understanding its application fields and working principle, it can benefit many areas where power needs to be controlled accurately.

Application Field: The TN805-600B-TR, or SCR, is a power-switching device and is commonly used in applications such as motor control, power supplies, inverters, and rectifiers. It is also commonly found in automotive, aviation and consumer electronics consumer goods such as TVs, Hi-Fi systems and gaming consoles. As a result of its high-performance characteristics, the TN805-600B-TR is often used in power grids for distributed power control systems, in emergency lighting operations, and in lighting systems in cars, aircraft and ships.

Working Principle: The TN805-600B-TR has two operational states - on-state and off-state - that are dependent on the gate voltage applied to the SCR. When the gate voltage is not present (no applied voltage), the SCR is said to be in the off-state. On the other hand, when the gate voltage is applied (gate voltage is present), the SCR is in the on-state. When the SCR is in the on-state, current can flow through it, allowing the power control applications to be performed. Conversely, when it is in the off-state, current cannot flow, meaning that no power is being transferred.

The TN805-600B-TR also has a unique feature known as “triac snubber” that allows it to reduce the losses that occur when it is switched off or on. This snubber is fitted with a resistor-capacitor network that is used to reduce current and voltage spikes, which improves the SCR’s ability to withstand high-voltage and high-current switching operations. As a result, the TN805-600B-TR can be used in applications that require handling significant power in an efficient and reliable manner.

Overall, the TN805-600B-TR is a reliable and robust SCR used in power control applications that require the switching of high currents and long conduction times. Its ability to reduce losses by utilizing the triac snubber, as well as its excellent current and voltage handling capacity, makes it an ideal choice for applications in areas such as motor control, inverters, rectifiers, power supplies and distributed power systems.
