Thyristors are solid-state electronic switches that are used in a variety of applications, including control, switching, and rectification. The C390P is a three-terminal, three-phase, SCR-type thyristor. It is widely used for power control applications and has many advantages over other kinds of thyristors.

The C390P is a reverse-blocking triac thyristor with a high current rating, low On-state voltage drop, and fast switching time. The C390P has a maximum load current rating of 200A, an On-state voltage drop of 0.5V and a switching time of 50ns, allowing it to handle large currents and high power. It is also designed to provide high noise immunity, allowing it to be used in noisy environments without interference.

The C390P is primarily used in power applications, such as motor control, light dimming, and AC/DC converters. It can also be used in AC phase control applications, such as heating elements, electric hot plates and space heaters. In addition, it can be used in line or load commutations for power factor correction and peak current control for power supplies.

The C390P’s working principle is based on the SCR (silicon-controlled rectifier) principle. An SCR is an electronic device that consists of two P-type and one N-type semiconductor layers. A DC gate voltage is applied across the anode and gate, which causes the current to flow from the cathode to the anode. The SCR can then be triggered into a conductive state by a brief, positive voltage pulse.

When the C390P is in the OFF state, no current flows through the device and the gate voltage is blocked. When a gate voltage is applied, the C390P switches to the ON state and the gate voltage is allowed to pass through the device. When the gate voltage is removed, the C390P switches back to the OFF state and the gate voltage is blocked. The C390P can be triggered into its ON state by a short positive pulse of the gate voltage.

In summary, the C390P is a three-terminal, three-phase, SCR-type thyristor. It is widely used for power control applications and is designed to provide high noise immunity. It has a high current rating, low On-state voltage drop, and fast switching time. The C390P’s working principle is based on the SCR principle and it can be triggered into its ON state by a short positive pulse of the gate voltage.
