Thyristors, also called silicon controlled rectifiers (SCRs), are a type of semiconductor that acts as a switch, letting electric current flow through them when triggered by an external signal.Modules are electrical systems that are typically composed of several electronic components and are used in circuit designs.The DT430N22KOFHPSA1 is a thyristor - SCR - module designed as an Over-Voltage Trip/Protection device, which is used to protect power supplies from overvoltage damage.

Application field

The DT430N22KOFHPSA1 thyristor - SCR - module is most often used as an overvoltage trip/protection function in power supplies.It is used to protect power supplies from damage due to overvoltage.It is suitable for electronic ballast, LED lighting, solar panel, LED drivers, telecommunications and other electronic systems.

Working Principle

The working principle of the DT430N22KOFHPSA1 thyristor - SCR - module is based on the basic thyristor on-off principle.When the voltage on the main gate exceeds the trigger voltage of the thyristor, it will turn on and allow current to flow through it.The thyristor - SCR - module has two other terminals, the auxiliary (Aux) and cathode (C), which act as an additional control over the device.

The Aux terminal is set to a much higher voltage level than the main gate, so the thyristor can only turn on when both the main gate and auxiliary voltages reach a certain level.When this occurs, the device will conduct current between the main gate and the auxiliary terminal.When the voltage on the main gate drops back below the trigger voltage of the device, the device will turn off.

The cathode terminal works similarly to the auxiliary terminal, but is set to a much lower voltage level than the main gate.When the voltage on the main gate falls below the threshold voltage of the device, the device will turn off and not allow current to flow through it.

The DT430N22KOFHPSA1 thyristor - SCR - module is designed to be used in device protection applications, as it limits the maximum and minimum voltage on the main gate, which acts as protection against over-voltage and under-voltage conditions.The device also has a built-in thermal protection feature which prevents the device from overheating when it is used for extended periods of time.

In addition to its protection functions, the DT430N22KOFHPSA1 can also be used as an on/off switch in electronic circuits.It is an ideal choice for power control applications as it can provide reliable switching performance with minimal power losses.
