Thyristors, or silicon controlled rectifiers (SCRs) are solid-state, three-terminal electronic switching devices which are used in a wide range of electronic applications. They provide a unique function known as either AC current control, or voltage control. Today’s modern thyristors are an integral part of many industrial and consumer products.

TD251N18KOFHPSA1 is a type of thyristor, also known as a bidirectional thyristor, manufactured specifically as a rugged and reliable device used for AC power control in a variety of applications. It comes with a number of advantages that make it suitable for its purpose, such as low loss, wide operating temperature range, low gate currents, and high noise immunity.

Application Field: TD251N18KOFHPSA1 is most commonly used in AC motor control applications like air conditioners, refrigerators, washing machines, and other large appliances. It can also be used as a general purpose AC power control switch for lights, fans, and industrial equipment.

Working Principle: TD251N18KOFHPSA1 operates on the principle of phase angle control, where the AC power to the load is controlled by varying the phase angle of the AC waveform. This is done by controlling the thyristor\'s conduction angle by controlling the gate current. This is done by applying a custom designed gate drive circuit that provides the desired conduction angle.

The TD251N18KOFHPSA1 can be operated in two modes, the first being continuous conduction mode (CCM) which is used to reduce the average current of an AC load. The second mode is phase cut mode (PCM) which is used to phase shift the AC waveform, resulting in a reduction of power to the load. This allows the load to be controlled in a variety of ways depending on the application.

Overall, the TD251N18KOFHPSA1 is an ideal choice for a variety of AC motor control applications due to its combination of ruggedness, reliability, low loss, wide operating temperature range, low gate current, and high noise immunity. It is a cost-effective solution for controlling AC power to a wide range of industrial and consumer products.
