SJ6004DS2TP

Thyristors - SCRs form one of the main components of power electronics, playing an invaluable role in the reliable transmission and control of electric power. Come in a variety of types, SCRs are semiconductor systems equipped with multiple terminals, which when energized turn on, thus passing current in the forward direction and tending to remain on even after the energizing current is removed. The SJ6004DS2TP is one such SCR and is used in applications ranging from motor drive controls, resistive heating and photovoltaic inverters, to active power filter controls, automobile battery chargers, welders and boiler applications, among other industrial and commercial applications.

Application Field

The SJ6004DS2TP is typically used for applications that require a High DC-Link Voltage, where currents up to 600A with short surges up to 750A can be sustained. These applications include:

• Motor Drive Controls
• Welders
• Boiler Applications
• Variable Speed Drives
• Machine Tools
• Photovoltaic Inverters
• Electric Vehicle Chargers
• Power Conditioners
• Industrial Heating
• Active Power Filters
• Battery Chargers

In addition, the SJ6004DS2TP has passed the specified requirements of UL5085-1:2013 for photovoltaic inverters, UL508C:2014 for industrial control panels, and UL627:2011 for boilers. As such, it can be safely used in the mentioned applications.

Working Principle

The SJ6004DS2TP is an SCR, a type of thyristor, which is a three-terminal semiconductor device in which a gate signal is used to switch on current flow through the device. When positioned in a circuit, the gate voltage needs to be applied to turn on the thyristor, followed by trigger current through the gate, before current can be allowed to flow in the forward direction. This process is known as commutation, and is what allows the thyristor to “switch” the current on or off, depending on the application. It is this commutation process that makes the thyristor such an essential power-control tool in modern electronics.

In the given case of SJ6004DS2TP, its maximum operating voltage is 600V with a maximum current load of 600A, and surge currents up to 750A. The device also includes a high-voltage pulse generator to provide rapid turn-off, particularly for hobbyist electronics projects.

Conclusion

In conclusion, the SJ6004DS2TP is a powerful SCR that can be used in applications ranging from motor drive controls, welders, and boiler applications, to active power filter controls, vehicle chargers, and more. It is a reliable device that has passed the UL safety standards for photovoltaic inverters (UL5085-1), industrial control panels (UL508C), and boilers (UL627). Its working principle is based on the commutation process, which allows the device to switch current on or off, depending on the application.
