Thyristors - SCRs

Thyristors are a subtype of solid state semiconductor devices known as Silicon Controlled Rectifiers or SCRs and are used in a wide range of applications. The name “Silicon Controlled Rectifier” or SCR was coined because the device is a rectifier and is made of silicon. SCRs are four layer devices consisting of a PNPN layer stack where a firing voltage is required to turn the device on, and then it will conduct current until the current flow is stopped or reversed.The SCR C150M is an ideal solution for high current switching applications, such as motor control and contactor control. The C150M provides fast switching, high voltage blocking, high current performance, and high surge capability. The device is able to switch up to 150A peak at 600V and withstand up to 1700V peak surge. The C150M is rated for continuous operation from -40C to +120C.The working principle of the SCR C150M is based on four layers of material put together in a PNPN structure. This structure functions as a voltage-controlled switch, which can be turned on or off by controlling the applied voltage. An SCR can be turned on by applying a positive voltage on the gate with respect to the cathode of the device. This causes a small current to flow, which causes an avalanche breakdown of the PNPN structure.When an SCR is in the on-state, the current flowing from the anode to the cathode can be controlled by altering the voltage drop applied to the gate. This makes an SCR widely applicable to various types of switching and control applications. The current rating of the SCR C150M is limiting; this means that the device will not allow any current flow in excess of the rated value to pass through it.The SCR C150M application field can range from low voltage DC and AC applications, to high voltage AC circuits. Its fast switching capabilities make it an ideal choice for motor control and contactor control. In the power electronics field, the SCR C150M has applications in power factor controllers, switching mode power converters, or in power supplies or UPS systems.SCRs can also be used in over and under voltage protection circuits, providing a latching function. The device will detect a voltage transient condition and latch so that the power is turned off. This feature is very useful in industrial applications, where circuit protection is essential.SCRs are also widely employed in electrical safety switches, used in electronic control systems to ensure user safety and in machines to protect from hazardous conditions such as electric shock. Medical applications of SCRs can include power control for respirators, ventilators, and infusion pumps.In summary, the SCR C150M is an ideal solution for a wide range of applications because of its high current and voltage blocking capabilities, fast switching action and surge capabilities. The device can be used in power factor controllers, power supplies, UPS systems, and in over and under voltage protection circuits. The SCR C150M is also widely used in electrical safety switches in user safety and in machine protection circuits. The device provides a convenient and reliable method for switching current in various types of applications.
