Thyristors - SCRs (Silicon Controlled Rectifiers) are power semiconductor devices that can be utilized for a number of applications. A CR05AM-16A#B00 is an example of an SCR, specifically characterized as a bidirectional, four-quadrant programmable gate turn off thyristor. This type of device is appropriate to use in applications that require logic control, gating and motor braking when utilizing alternating current.An SCR can be described as a four-layer semiconductor device, totally encapsulated and constructed of two P-type layers sandwiching a layer of two N-type layers and devices that respond to the gate control signals by controlling the movement of a current between the two electrodes.When no gate control signal is applied, the SCR is `on’ and allows current to flow between the two electrodes; when a gating voltage is applied, the SCR is turned ‘off’. The main purpose of an SCR is to provide a programmable switching control in alternating current motors. Since SCRs are easily programmable, they can be used in single or multiple winding configurations and applications, such as for controlling the speed and direction of pumps, fans, machine tools and industrial conveyors.An SCR or a CR05AM-16A#B00, can handle a nominal voltage of up to 1600V and a nominal current of up to 16A. Along with its high performance, this type of SCR can achieve up to 825 Amps peak non-repetitive current and up to 5500 Amps peak repetitive current. The device’s maximum forward trigger current can range from 0.18A to 0.27A, while its reverse trigger voltage has a range of 4.5 volts to 6 voltsThe working principle of a CR05AM-16A#B00 is based on the fact that the device remains off until a low voltage is applied to its gate. As the gate controls current flow into the SCR, it must be kept at a certain voltage, which is considered to be high enough to turn the SCR on. Once the voltage is applied, a small current flows through the gate, creating a channel between the two N-type layers. The SCR is then turned on, allowing current to flow from the anode to the cathode. When the control current, applied at the gate, is removed, the SCR turns off. This is because the small current passing through the gate is no longer sufficient to flow from the anode to cathode. As a result, the channel breaks down and the flow of current is cut off.In summary, the CR05AM-16A#B00 is a bidirectional, four quadrant programmable gate turn-off thyristor (SCR) specifically designed to be used in applications involving alternating currents. With a voltage range of up to 1600V and a current range of up to 16A, its main purpose is to provide programmable switching control. The SCR works by turning on after a low voltage is applied to its gate and turning off when the control current applied at the gate is removed. Overall, SCRs are versatile and highly efficient devices appropriate for a variety of applications requiring reliable logic control and motor braking.
