Introduction to T9K7340803DH

T9K7340803DH is a 800V, 3.4A, 12A/13A SCR module developed and produced by American Power Devices Corporation (APDC). It is designed in an ultra low loss, high temperature, hermetically sealed ceramic carrier package that provides protection to the silicon controlled rectifier (SCR) and anode passivation against corrosion and potential junction failure. It is a robust solution for switching power applications in harsh environments.

Application Field and Working Principle of T9K7340803DH

Thyristors, or SCRs for short, are a type of semiconductor component that allows current to flow only in one direction, just like a diode. SCRs are commonly used in many applications, especially in power controls, such as motor speed control, light dimmers, power supply controls, and more. The main application of the T9K7340803DH is in motor speed control and more.The T9K7340803DH works by allowing current to flow when a certain voltage is applied on the anode. As soon as the voltage is applied, the SCR acts as a switch and allows current to pass through. The current flows until it is interrupted by either turning off the voltage supply or disconnecting the circuit. It is important to note that the current can only flow in one direction and this is determined by the direction of the internal bridge electrodes of the SCR.The T9K7340803DH is a robust solution for controlling the power in applications that have high temperatures and corrosive environments. It has an optimal operating temperature of up to +150ºC and an anode corrosion protection feature for enhanced reliability. The module also features a low-loss design and a fast switching time.

Conclusion

The T9K7340803DH is an SCR module designed and manufactured by APDC and is designed for applications in power control, motor speed control, light dimmers, and power supply control. The module works by allowing current to flow when a certain voltage is applied on the anode. It has an optimal operating temperature of +150°C and a corrosion protection feature, as well as a low-loss design and a fast switching time.
