Thyristors - SCRs
Thyristors are a class of electronic semiconductor devices which are made up of multiple layers of semiconductor material, typically working in groups of four, between two terminals. The purpose of a thyristor is to control the flow of electrical current between the two terminals by either allowing or blocking it, depending on certain conditions. One of the most common types of thyristors is the SCR (silicon-controlled rectifier).

The T700083004BY SCR is a fast-intrusion, fast-recovery, low-loss, high performance power switch. It is a four-layer semiconductor device specifically designed to control and manage heavy loads with a wide range of current capabilities and voltage ratings. The main technical specifications of the device are 1000V, 87A, and 800W constant power. The SCR has a low VCE(SAT) (Voltage Collector-Emitter Reverse Saturation) of 0.37 V, a fast turn-off time of 10μs, an efficiency of up to 97% and an on-state resistance of 0.060 ohms. These properties make it suitable for use in power supplies, motor drives, lighting circuits and other heavy-duty applications.

The T700083004BY SCR is mainly used in the industrial automation sector for controlling large power loads. It is typically used to switch heavy loads such as those found in motor drives, 3-phase systems, multiple power supplies and HVAC systems. The device is suitable for a wide range of applications, including DC motors, AC drives, soft starters, programmable logic controllers, lighting systems, welders, and power converters. It can also be used in automotive and aerospace applications as it is highly reliable and able to handle high currents and voltages.

The working principle of the T700083004BY SCR is that it allows or blocks electrical current flow through its terminals depending on the applied voltage. The device can be turned “on” or “off” by applying a voltage difference between the anode and cathode. When the anode is held at a higher potential than the cathode, the SCR will turn “on” and allow current to flow. When the reverse voltage is applied across the two terminals, the SCR will then turn “off” and no current will flow. This type of SCR is known as an “on-off switch” and can be used to control the power of larger electrical devices. It is also useful for protecting electronic circuits from potentially dangerous over-currents and over-voltages by turning the SCR “off” when these conditions are detected. The T700083004BY SCR can be triggered manually or via an electrical signal, making it highly suitable for remote and automated control.

In conclusion, the T700083004BY SCR is a highly reliable and efficient power switch that is well suited to a wide range of different applications, ranging from industrial automation to automotive and aerospace. It offers excellent performance in the form of fast turn-off and on times, low VCE(SAT) and low on-state resistance, while also having the capability to protect circuits from potentially damaging over-voltages and over-currents. With these features and its ability to be manually or remotely triggered, the T700083004BY SCR is a powerful, reliable and versatile device for controlling high-power electrical devices.
