TDB6HK165N16LOFHOSA1

TDB6HK165N16LOFHOSA1 is a module of Thyristor (SCR) which is popularly applied in various industrial control systems. To understand the application and working principle of TDB6HK165N16LOFHOSA1, firstly it is essential to have a clear knowledge about Thyristors. A Thyristor (also known as silicon controlled rectifier) is a semiconductor device with four layers of alternating P-type and N-type material, consisting of alternating N-type and P-type semiconductors. It is during the “on” state when the gate current is applied, forming what is known as the forward breakover state and it is during the “off” state when the gate current is removed, resulting in the reverse breakover state.

TDB6HK165N16LOFHOSA1 module uses 16 pieces high current SCR and several pins for both control and AC power. As module type thyristor, it has advantages of high input current, high efficiency and long life, so it is widely applicable to the AC circuits with high-voltage, high-current and high-power control and the characteristics of convertor AC motor speed, converter motor control and frequency controlling. TDB6HK165N16LOFHOSA1 is an ideal choice of motor controlling devices and power process.

The primary application and working principle of TDB6HK165N16LOFHOSA1 module is to control the power in the AC and DC circuits. Its working is based on the fact that the SCR has three basic states i.e. forward breakover (on), reverse breakover (off), and forward blocking (tripped) state. In a practical circuit, the forward breakover state is the normal operating condition and the reverse breakover state is usually achieved by shorting the gate to the main terminal. When the gate receives enough current, the SCR will forward breakover providing power to the circuit. While, if the SCR is tripped and the reverse breakover state is reached, the power will be cut off from the circuit.

In short, the main application field of TDB6HK165N16LOFHOSA1 module is in controlling the power in AC and DC circuits. The working principle of this module is based on its SCR components, which has three basic states, the forward breakover, the reverse breakover and the forward blocking state. This module is highly preferred in the areas with high-voltage, high-current and high-power control, such as the motor speed controlling, motor controlling and frequency controlling, due to its high input current, high efficiency and long life.
