Thyristors - SCRs - Modules

The TZ425N08KOFHPSA1 is a components of a type of semiconductor device called thyristor or silicon-controlled rectifier, abbreviated SCR, which is a principle type of solid state power switching device. A thyristor module is a combination of two or more thyristors that are encapsulated into a single package in order to simplify assembly and testing and reduce the overall production cost. Specifically, the TZ425N08KOFHPSA1 is a fast recovery, high voltage thyristor module with a forward blocking voltage capability up to 800 V, reverse blocking voltage capability up 800 V, on-state current of 425 A, and off-state current of 100 mA.

Application of TZ425N08KOFHPSA1

The TZ425N08KOFHPSA1 has a wide range of applications in power switching, phase control and rectification. For example, the thyristor module can be used for voltage regulation in power inverter and AC phase control, as well as in applications such as DC motor control, UPS, HVAC, lighting, solar and wind power systems, etc. The thyristor module can also be used in industrial motor control, rectifier, welding machine, and other applications.

Working Principle of TZ425N08KOFHPSA1

The TZ425N08KOFHPSA1 works in two ways, as a switch and as a rectifier. As a switch, it functions like a transistor, by providing a high resistance path in the off state and a low resistance path in the on state. As a rectifier, it can be used to convert AC power to DC power, or vice versa. The TZ425N08KOFHPSA1 is a combination of two transistors, a PNP and an NPN, combined in a special arrangement. This arrangement allows the thyristor module to control the flow of current by changing the voltage on it. When the voltage is increased, the PNP transistor is turned on and the NPN transistor turned off. This allows the thyristor to control the flow of current. When the thyristor is turned on, the voltage across it drops and a current starts to flow. The thyristor will remain in this on position even when the voltage across it is reduced, but when the voltage across it is increased, it will be turned off again.

The TZ425N08KOFHPSA1 is a popular choice for power switching, phase control and rectification applications due to its high voltage, high current, fast recovery, and low operating power. The thyristor module is also an ideal choice for applications that require tight current control and efficient power control.
