Thyristors are a type of semiconductor device usually used in power switching applications. They are often referred to as silicon-controlled rectifiers, or SCRs. The C184M, or four-quadrant bidirectional thyristor, is used in applications that require power switching in both directions.

The C184M is engineered with two SCRs that are electrically connected in parallel, each with its own independent gate. The device is available in both insulated and non-insulated packages, with the insulated packages designed to handle higher power loads.

In terms of application field, C184M is used in high-power bridge configurations as well as in many other circuits where bidirectional power handling is necessary. It has high capacitive and inductive load-handling capabilities, particularly in AC switching applications. The device is also suitable for power control systems, including those that require critical timing and die-level integration.

In terms of working principle, C184M works similarly to the single-directional thyristor, but with two additional components in the circuit – an anode and a negative base electrode. When the gate current reaches a certain level, the SCR begins to conduct, allowing current to begin flowing between its anode and cathode.

The two additional electrodes (the base and gate) control the gate current and therefore the duration during which the SC R is activated and deactivated. When deactivated, the negative base current keeps the gate voltage at more negative levels, acting as a signal for the SCR to stay shut off.

The C184M can reverse current flow from anode to cathode and back, depending on the base and gate voltages. This bi-directional switching capability is quite useful in the field. For instance, the device can be used to switch load or power supplies, or to provide adequate protection against overload currents in a circuit.

It is also important to note that the C184M can be used in circuits with a wide range of conditions, including high-power AC, pulse signals, and DC. This makes it a versatile device that is used in numerous applications.

Overall, the C184M is a four quadrant thyristor that has a wide range of uses in power switching applications. Its bi-directional flow capabilities, together with its high capacitive and inductive load-handling capabilities, make it a highly versatile device suitable for use in a variety of circuit designs.
